What would happen if a person who is wearing a heavy winter jacket were to place a thermometer inside the jacket next to his or her skin? Students will investigate the phenomenon of placing two spoons, one metal and one nonmetal, into a mug of hot water. This explanation, called "pressure melting", originated in the 19th century. The water formed between the edge of the skate and the ice surface provides a nearly frictionless movement so the skater flies across the ice. Guidance: Now that students have built some direct experiences and begun to wrestle with ideas about thermal energy and temperature, you will want to support them in obtaining and making sense of some scientific information. My understanding of ice skating is that it has to do with the pressure of the skate, melting the ice and you skate on the melted water. These products attract moisture to themselves to form a liquid brine solution, which can generate heat and melt the ice. Students engage in science and engineering practices to make sense of science ideas about energy. Read through the probe with students or give them time to read through it. Excellent drainage is key to keeping ice melt dry; distributors do not want water pooling underneath the pallets. Ice melts under pressure. Today’s task, Why does the ice melt faster?, provides an opportunity for students and their families notice and wonder about a related phenomenon - ice cubes melting at different rates on two different household objects from the same room in the house. COMING IN APRIL 2021; NOW AVAILABLE FOR PREORDER The Daily Do is one of the ways NSTA is supporting teachers and families with this endeavor. Figure 2 Making Sense of the Investigation: Use the following prompts to help students make sense of the investigation. Students should record observations (“I see…”), possible explanations of the phenomenon (“I think…”), and questions that they would like to investigate (“I wonder…”). Adult supervision and careful handling should be employed to reduce the risk of burns. When this melting action slows, adding more compound has no impact on lowering the eutectic temperature, thus, the ice melts no faster. Say to students, “We noticed the blocks’ temperatures were the same at the start of the investigation. Group A object (one from the following list), *copper, cast iron, aluminum or steel (includes nonstick-coated cookware), Group B object (one from the following list), thermometer, optional (infrared, [aquarium] liquid crystal strip, or meat thermometer). ... btw u can stop ice from melting if u keep light away from it. Students might use words, pictures, and/or symbols. 1840 Wilson Boulevard, Arlington VA 22201 Select two ice cubes as close as possible to the same size and shape. and are dedicated to helping students and their families find balance between learning science and the day-to-day responsibilities they have to stay healthy and safe. What is the temperature in this room? If you are using a thermometer, then now is a good time to call students’ attention to the fact that the room temperature and the temperature of both spoons are all the same. The energy gained from the hot chocolate caused the particles in the spoon to move faster. Guidance: Investigation 1 allowed students to experience and explore the ice melting phenomenon first-hand. External forces, such as pressure and friction, can melt the ice. How do I fix this? That is why you can ice skate. The amount of ice that is melted by a given quantity of ice-melt compound will decrease as the temperature of the mixture is lowered. You can use ice melt to keep sidewalks from forming ice and to melt ice that has accumulated. the same) the water changes to a liquid. (ice seems to melt faster on metal objects than on nonmetal objects, ice seems to melt faster on objects that felt “cooler” to the touch, the starting temperatures of the objects were the same, etc.). Namely, energy is spontaneously transferred out of hotter objects to colder ones and when two objects interact, and energy can be transferred from one object to another through collisions (even when those objects are molecules). Early attention before a storm will help prevent the formation of ice. Share the “Hot Spoons” probe with your students. You can find additional prompts in STEM Teaching Tools Practice Brief 41: Prompts for Integrating Crosscutting Concepts Into Assessment and Instruction. You can use the discussion questions from the lesson to help students summarize the new information they obtain from the lesson. Then have students share their responses and thinking. What would happen if we took the same jacket, after it had been hanging in a closet, and placed a thermometer inside? The lowest melting point of the water and ice-melt compound solution is termed the “eutectic” temperature. A glacier can exert a sufficient amount of pressure on its lower surface to lower the melting point of its ice. Join 102,227 other online Players! Its already starting to cut in there, it's amazing. As adults we may be tempted to give students the questions we feel might be important to explore, however we need to refrain from this and allow our students to practice asking their own questions. Three-Dimensional Learning Ice melt typically has a two-year shelf life if stored properly. Microwave (Alternatively, you can use a kettle or small pot to heat water on a stove or an electric kettle.). Keep these key points in mind when using ice melt: It’s important that your organization assess your needs for application of ice-melt compounds. Guidance: In the absence of melting blocks, students will use household materials to help them figure out why the ice melts faster on one block than the other. – Though a variety of commercial ice melting products is used nowadays that contain complex combinations of salts and act very fast, of the common salts, calcium chloride is known to melt fastest, even at temperatures as low as -25 o F (-32 o C). 2. How does the energy flow in this investigation compare to the energy flow in Investigation 1? © 2021 NSTA, Crosscutting Concepts-Disciplinary Core Ideas-Is Lesson Plan-NGSS-Physical Science-Science and Engineering Practices-Three-Dimensional Learning-Middle School-6-7-8. There are more hydrogen bonds between the molecules of ice than in water. Consider using the following guidance to support students in developing an initial model to explain their observations in Investigation 1. Your model should also show how the parts of the system interact. In addition to the original phenomenon, this video shows the initial temperature of the blocks and shows how the blocks interact with heat-sensitive liquid crystal sheets. Then tell them to save their models/put them away until later. Luckily for us, liquid water is most dense at about four degrees Celsius. |, HOMEOWNERS ARE LIABLE FOR ICE AND SNOW REMOVAL, Ice-melt compounds are only effective down to a specific temperature, The temperature of the air, pavement, and the type of ice-melt compound used will affect the rate at which snow and ice melts, Where around your facility to use ice melt, Whether the area has access to traffic and sunlight, which affects the overall effectiveness of ice-melt compounds. Please subscribe to my channel and feel free to comment - Odie would love to hear from you. The water formed makes the skates slide easily over the ice, reducing friction. Be sure that you are incorporating ideas from Investigation 2 and from the interactive lesson. Give students an opportunity to revise or add to their models. Contact Kissner Milling Company Ltd. today for all of your Ice Melter needs. How do these patterns help you explain why the ice melts faster on some objects than on others? https://www.kissner.com › ice-melt-101-what-you-need-to-know-about-ice-melt The ice cube radiates heat to your hand.D. The template shows the object and the ice cube. Yet, why does the same fan warm an ice to make it melt faster? You might use the following script. Log in Register. You can't skate on a smooth rock surface, or glass, at Earthly temperatures and pressures, because no liquid lubricant can be produced. Which type of salt melts ice the fastest? You can prompt students’ thinking about heat by using the, Uncovering Student Ideas in Physical Science, Volume 3, Predict, Observe, Explain: Activities Enhancing Scientific Understanding, You can learn more about using formative assessment probes by reading the. Does it make sense to investigate this question next?”. However, to be picky, the blade doesn't melt the ice. Visit the NSTA homepage. How did these patterns compare to your predictions? You can use the following question to prompt students’ thinking as they view and process the video. Look at the phase diagram of the water. Revisit the “Hot Spoons” probe. Where have the spoons been? ", You might say, “Many of us are wondering what the temperature of the blocks are before you put the ice on them. Use the “zoom-in circles” to show what you would see at the microscopic level if you had a special tool that allowed you to do so. Ice-melting compounds lower the freezing point of water. The second law of thermodynamics puts constraints on how energy flows in a system. Pet-Friendly Ice Melt. Keep in mind that even if it is the ideal crystal blue, you’ll still want to stay off the ice if it’s less than 15 centimetres thick. Heat is the transfer of thermal energy, in this case by conduction.) Teacher background: The best answer is Jamal’s: “I think heat from the hot chocolate moves through the spoon to my hand.” (It is thermal energy that is transferred from the spoon to Jamal's hand. However, one particularly warm winter, I went to an outdoor ice rink and the ice did melt. Investigation 2 engages students with an investigative phenomenon that will help them make sense of the transfer of thermal energy (heat). Guidance: Now, you will want to help students transfer their learning from the investigations and interactive lesson to revise their model of the ice melting phenomenon. 1. The only hard ice is on the surface. The NSTA Daily Do is an open educational resource (OER) and can be used by educators and families providing students distance and home science learning. Saturday: Closed Your model should show all the parts of the system. I have known the reason why skate can slide over ice is that water's melting curve in terms of pressure and temperature has a negative slope. It cools you off because it helps the moisture on your skin evaporate faster. Play Now. Is Lesson Plan The weight on the blade creates sufficient pressure where it contacts the ice to lower the melting point, causing the ice to melt at the contact point. Your hand transfers temperature to the ice cube. So, when you are skating, you’re skating on a thin film of water, which acts like lubricating oil. When snow starts falling, the ice melt will create a brine solution, helping to prevent ice from bonding to the surface. (If you haven't noticed, give it a try!) It's the pressure on the ice that causes it to melt. Ice begins to melt when its temperature exceeds 0 degrees Celsius and hydrogen bonds between water molecules break. Based on our models, most of us are wondering why the blocks’ temperatures changed at different rates. Has either of the spoons been heated or cooled? Is one of the blocks heated? Ice melt plays an essential role in many winter safety programs. If you're an NSTA member, you can add this collection to your library by clicking ADD TO MY LIBRARY located near the top of the page (at right in the blue box). The underlying water will be forced up by the weight and pressure of the snow in-between the liner and the ice, turning the snow into slush on top of the skating surface. If you have a thermometer, record the room (air) temperature. At this point, you want to press students to use evidence from the investigation to justify their explanations. Each weekday, NSTA will share a sensemaking task teachers and families can use to engage their students in authentic, relevant science learning. Prompt students to clarify their thinking, but be careful not to give away the explanation at this point. Disperse ice melt properly. Using too much product can damage surfaces and harm the environment. This can be the blade of an ice skate, the sole of your shoe, or the tire of a car. The ice doesn’t melt because the rink is designed to stay cold enough so that such a thing does not happen. its common vanilla knowledge breh. Find or locate the coolest part of your backyard. Give students time to reread and respond to the probe. Opaque white ice is isn’t quite as strong, while grey or black indicates that there’s water present; the ice may be melting or have air pockets. In making ice rink, you should always consider the temperature where you will put or place the rink. NSTA has created a Why does the ice melt faster? And I don't mean because the ice has melted! Whether this community of learners is made up of classmates or family members, students and adults build and refine science and engineering knowledge together. You might choose to put students into small groups and share their models. Can you explain why you feel warm when you are standing near a campfire? As I understand it, skating involves creating a thin layer of liquid water. Access the entire collection of NSTA Daily Dos. A fan cools you on a hot day. What patterns did you observe? Moisture is the biggest culprit in damaging these products. “Leave no alternative science idea unchallenged!” could be the slogan of this second edition o... National Science Teaching Association Ask students to record their answer and explain their thinking. Share As ice melts, the air around it becomes colder. Some students may also benefit from writing things down first before they share. Ice is the solid form that liquid water takes when it is cooled below 0 degrees Celsius (32 degrees Fahrenheit). Have students use their models to explain why the ice melts faster on one block than the other, and have them infer the type of material for each block. Why does the ice cube melt when you hold it in your hand?A. Students engage in science and engineering practices to make sense of science ideas about energy. Server IP » mc.hypixel.net. Use the zoom-in circles to show what might be happening at the microscopic level that can help you explain your observations. The underlying water will be forced up by the weight and pressure of the snow in-between the liner and the ice, turning the … How do they feel compared to the temperature of the room? Then ask them to develop an initial model to explain why the ice melted faster one object than another object. Students do science and engineering through the science and engineering practices. Answer: Air from a fan is not really colder, it just feels cold. If it gets colder, more water becomes ice. Say, "Think about what causes ice to melt and why it might melt faster on some materials than others. Are there any other components that you need to include? Students will investigate the phenomenon of placing two spoons, one metal and one nonmetal, into a mug of hot water. Revisit the original phenomenon by watching this extended, Teacher background: You can find an explanation of the ice melting blocks in the, Investigation 1: Melting ice on two different kitchen objects, STEM Teaching Tools Practice Brief 41: Prompts for Integrating Crosscutting Concepts Into Assessment and Instruction, “Why is my shadow always changing?” Daily Do, Investigation 2: Temperature of two different kitchen spoons in hot water, Middle School Chemistry Lesson 2.1 on Heat, Temperature, and Conduction, Flinn ChemFax Lesson Plan: Ice Melting Blocks. However, it can be taught as part of an instructional sequence in which students coherently build science ideas about water's ability to absorb, store and release large amounts of energy. If that does happen, Shariff says you just need to wait until the temperature rises. Select one object from Group A and one object from Group B. Optional: Thermometer - A meat thermometer or a surface thermometer would work equally well for this investigation. Make a prediction about what will happen when you place an ice cube on each object (simultaneously). The quantity of ice-melt compound needed to lower the freezing point of ice to the eutectic temperature is called the “eutectic concentration.” At this lowest temperature, the rate at which ice melts is very slow. Does it make sense to investigate this first?”. This is because the water expanded as it froze. The proper coverage rate is about one cup per square yard. What information would you need in order to predict whether transfer of thermal energy would occur when two objects or materials interact? This helps to prevent snow from becoming hard-packed on surfaces. (Is one block hotter than the other? As the ice melts, the compound solution’s concentration is reduced and the freezing point of the water starts to increase until such time that more ice-melt compound is spread on the ice and water. How is each part of the system affecting other parts of the system? Have students place the two spoons into the hot water and let them sit for 5 minutes. For each object you tested in Investigation 1, revise your initial model to explain why the ice melted faster or slower on that object. Safety Note: Students will be working with hot water. You might ask students to turn to a partner and share their ideas. If you have a microwave available, then microwave 6 ounces of water in a microwave-safe mug for 90 seconds. Contrary to popular opinion, using large amounts of ice melt does not affect the speed which ice and snow melts. Students can use this additional evidence to support their explanations. Kitchener, Ontario Start a Discussion, Crosscutting Concepts How do the objects feel temperature-wise compared to each other? (T) 703.243.7100 (F) 703.243.7177 Now, you will want to help students transfer their learning from the investigations and interactive lesson to revise their model of the ice melting phenomenon. If ice were denser than water, you’d never get to go skating on frozen ponds or lakes. This coverage will fan out and undercut the ice, so that you can shovel the walkway clear. Magnesium chloride works down to 5°F while calcium chloride works down to -20°F. Guidance: It is important to allow time for thinking. During a thaw in ice less than three inches thick, grain boundary melting can take place in a couple hours in warm conditions, especially in the spring when the sun is strong and the days are long. (both objects were the same starting temperature but one felt colder than the other, the objects that felt cold had/caused the biggest changes - fast melting ice cube/highest temperature change). What might be happening at the microscopic level that helps us explain this? Select the right ice melt and apply correctly to reduce the chance for slips and falls this winter. An image of an ice crystal. Investigative questions are common questions kids may ask after they are introduced to the phenomena. When used correctly, ice melt is a powerful tool that can help keep ice from forming and reduce the risk of slips and falls. Using evidence from data collected in those investigations, students develop a model to explain their observations of the ice on each of two blocks. Middle School NGSS Teachers and families across the country are facing a new reality of providing opportunities for students to do science through distance and home learning. Let’s look at our thermostat. You don't need to melt the ice to skate on it, or need a layer of water as a lubricant to help slide along the ice. When the ionic compound salt is added to the equation, it lowers the freezing point of the water, which means the ice on the ground can’t freeze that layer of water at 32 °F anymore. The ice that my ice minions generate is melting and not allowing them to generate ice. Use an infrared heat gun to determine the surface temperature. If it gets warmer, more ice becomes water. Making Sense of the Investigation: Use the following prompts to help students make sense of the investigation. It may be helpful to watch the video multiple times and to revisit the see-think-wonder chart. Why does a carpeted floor feel warmer to bare feet than tile or wood even though all surfaces are the same temperature? 148 Manitou Drive, Suite 301, Kitchener, ON N2C 1L3, Phone: 1-800-434-8248 | Fax: 1-877-434-8250, Monday to Friday: 8am to 5pm We've probably all experienced the phenomenon of stepping from a carpeted floor to a bare floor and noticing our feet feel colder. Van Leeuwen explains that the tiny liquid layer is the reason why skates can start moving instantaneously on ice. Apply in advance of a winter storm. Observe the ice cubes and record how long it takes each ice cube to melt and anything else you noticed as the ice cubes melted. Heat from the ice cube is transferred to your hand.C. If the ice was weak yesterday from thaw conditions but feels hard and strong in the morning it may be an illusion. At this limiting eutectic temperature, solutions of the ice-melt compound aren’t effective and the melting action on the ice will cease. Tell students, “We are going to try this out, but with a twist. The ice cube which was solid has turned into the liquid water because the air temperature is warmer than the freezers. Which means the ice particles gather heat energy from the warmer air. The ice … Ask them, "What could we do to figure out some things about why one ice cube melted faster than the other? Students should have noticed that metal objects consistently feel “cooler” than nonmetal objects like the plastic/wooden spoon. Therefore the ice particles have enough energy to break apart (melt)into smaller particle arrangements. If you are concerned for the safety of your pet, you can choose a 100% organic, all natural, salt free ice melter, such as Safe Step “Sure Paws”. Y. After all the questions have been asked, we want to prompt our students to express their own ideas of how to figure out the answers to their questions. Grades 6-8. We are going to observe what happens when both a metal and nonmetal spoon are placed in hot water. Interested in learning about other ways NSTA is supporting teachers and families? If the pressure due to our mass increases sufficiently high, the ice starts to melt. Disciplinary Core Ideas Heat is transferred from your hand to the ice cube.B. Listed below are two groups of common kitchen objects. Students can learn more by exploring the animations and student reading from the Middle School Chemistry Lesson 2.1 on Heat, Temperature, and Conduction. Ice melt works by interacting with water and ice to form a liquid brine that in turn generates heat that melts the ice. The frozen water would become denser than the liquid water and sink below the surface. And again, don’t worry if you don’t have any thermometer, at all. The reasoning is that due to the high pressure the skates put on the ice, it will melt at temperaturs below 273 K and thus provide a thin film of liquid on which we can skate. You might have students use the following questions to organize their ideas from the investigations and interactive lesson: Now, prompt students to revisit their models for the ice melting phenomenon. Ask students to choose the student whose answer they think best explains why the metal spoon gets hot when placed in hot chocolate. is a stand-alone task. Observe the ice cubes and record how long it takes each ice cube to melt and anything else you noticed as the ice cubes melted. Use a mechanical spreader for accurate coverage. The other answers express common misconceptions about thermal energy and its movement. One, now more widely accepted, invokes friction: the rubbing of a skate blade or a shoe bottom over ice, according to this view, heats the ice and melts it, creating a slippery layer. What do you think might be happening at the microscopic level that would help you explain the patterns you observed? At 1 atm, the water is solid, but at higher pressures (keeping the temp. Warmer objects transfer energy to cooler objects, not the other way around. Ice melts due to the chemical properties of water. Investigation 2 engages students with an investigative phenomenon that will help them make sense of the transfer of thermal energy (heat). If you have just filled your rink and it froze over with a little ice and you get a big snow storm, the weight of the snow on the ice will force the ice downward. Think about these questions. Share the model scaffold with students or ask them to refer to the scaffold pictured below and draw their initial models on blank paper. – Epsom salt does melt ice, but it takes longer than table salt. This probe is based on the “Cold Spoons” probe from Uncovering Student Ideas in Physical Science, Volume 3 and on the “Hot Spoons” task from Predict, Observe, Explain: Activities Enhancing Scientific Understanding. Use the following prompts to help students make sense of the investigation: What patterns do you observe in the data from both investigations? Sunday: Closed, 148 Manitou Dr, Unit 301 Guidance: Students will observe the phenomenon through the Amazing Ice Melting Blocks video (see above). Many students have ideas and questions but need time to formulate their idea or question into words. It becomes less dense when it becomes a frozen solid. Teacher background: You can find an explanation of the ice melting blocks in the Flinn ChemFax Lesson Plan: Ice Melting Blocks. ), Google what the blocks and/or ”ice” cubes are made of, Measure the temperature of the blocks before you put ice on them, Measure how fast the blocks’ temperatures change, Measure the temperature of the ice cubes before you put them on the blocks, metal* pot, pan, cookie sheet or mixing bowl (copper, cast iron, aluminum, or steel), glass or ceramic pot, pan, cookie sheet or mixing bowl. collection of resources to support teachers and families using this task. For example, tossing table salt (sodium chloride) onto ice when it's 0°F won't do anything more than coat the ice with a layer of salt. Remind students their models don't need to be perfect - they will have a chance to revise them after collecting additional evidence. Physical Science Place one ice cube on each object and start a timer/record your starting time. How does this help us understand the ice melting investigation? The Science: Applying pressure to ice has the effect of lowering its freezing point, which means it will melt to form liquid water above a certain temperature. What do you think is the same or different about the blocks? Did you ever stop to wonder how two floors in the same home (on the same level or story) could feel like they were at two different temperatures? It says the room is 72 degrees. Although questions may vary, many students will be curious about the ice melts at different rates on the two blocks even though they appear to made of the same material. Thermal energy from the hot chocolate heats the metal spoon, which is a good conductor, and the energy is then transferred from the spoon to Jamal’s hand. It was then mentioned as fun fact that you could ice-skate on a planet with lakes of frozen dioxide because that gas has the p (T) -curve the other way round. ), Are the blocks the same? Will Epsom salt melt ice? Ask students to note similarities and differences between their models. If a student is committed to an explanation other than Jamal’s, then press them to revisit the evidence from the investigation.
