Solid Gas
Frozen: Let’s Explore Ice Poems to Share
Solid A solid’s a solid. It doesn’t change shape. It can’t move around. It stays in one place Your desk is a solid And so is your chair .Just look in your classroom. Wow! They’re everywhere!
Gas Air is a gas. We can’t see it, that’s true. But often we feel it in things that we do. It keeps up a kite.
Air fills up a bubble Without it to breathe, We would be in big trouble
Liquid A liquid moves smoothly. We say that it flows From one place to another-how quickly it goes. We know that most liquids are easy to see. With no shape of their own, they’re not like you and me
What is Matter? Everything around us is made of matter. Matter is anything that takes up space and has mass (the stuff inside an object) Matter is in three forms: Gas, Liquid and Solid Gas: particles are far apart and move around a lot, they can change volume to fill a container
Liquid: particles are pretty close together and move around, can take the shape of the container but do not change volume Solid: particles are close together and don’t move, they stay in their own shape and do not change volume
Ice Treasures The day before you do this experiment, freeze some toys inside a variety of containers bowls or plastic deli containers etc. Fill the containers half-way with water, freeze for a couple of hours, then add small toys or objects and the rest of the water. You will also need: Some non-sharp tools for the students to chisel with. Spoons, craft sticks, toothbrushes
This day is designed to give the students some basic hands-on experience with ice. Put your frozen blocks into a tub or plastic bin and ask children to chip away at the ice until they get the toys out. This could take a while, depending on the size of the ice block. As the students work, some things they may notice:
Ice turns into water when it melts
Ice melts faster when it is touched with their hands
Larger blocks of ice take longer to melt
Ice is COLD and HARD!
Which is heavier? (Ice or water) Freeze 1 bottle of water the day before 1.
Ask the students to predict which they think is heavier, ice or water
2. Put the frozen water bottle on one size of the scale and the un-frozen bottle on the other side. Observe 3. Talk about what happened. 4. Ask the students what they think will happen when the frozen water bottle melts. Will the results of the experiment change or stay the same? Leave the bottles on the scale for the day and see what happens.
What Makes Ice Melt Faster? 1. 3 bowls with ice 2. Timer 3. Sand 4. Salt 5. Marker What to do: Fill the bowls with ice and label one bowl ICE, one SAND, and one SALT Place the salt on the ice marked salt, Place the sand on the ice marked sand. Set your timer for 10 minutes, observe your ice every 10 minutes
Why? Salt dissolves in water easily. This means that salt breaks down into tiny particles that mixes with water. This mixture has lowered the freezing point compared to standalone water. So when salt is the top of wet ice the salt dissolves in the water-like surface layer of the ice causing the ice to melt faster. Mostly the salt water does not refreeze. Now you know why road workers and other people sprinkle salt on icy roads and steps and sidewalks.l
Ice Excavation Ice cube tray, small objects that will fit in each ice cube (M&Ms, dried beans etc.l) Eye droppers, small bowls or cups, paper plates and a Timer Each group of 2 students will need 3 ice cubes, an eye dropper, a small bowl and a paper plate ( Pour a small amount of water in ice tray and freeze, add 1 small object to each cup in ice tray and cover it with water, return to the freezer) Working in partners, one child will be the melter the other the timer. Using the eye dropper drop cold water on top of the ice cube to melt the ice, continuing until she is able to remove the object from the ice. The “timer” keeps track of how many minutes passes from the start until the object is free and removed. Repeat using room temperature water and then warm water. Record the Minutes for each in their Science Journal or on a recording sheet you have provided.
The Science behind this experiment The freezing temperature of water in 32 degrees Fahrenheit. We know that cold water is not that cold because it is still liquid. So when cold water is dropped on top of the ice, it warms the temperature of the ice enough to raise it above the 32 degrees causing the ice to melt. Dropping warm water on the ice causes the temperature of the ice to change more quickly, making it melt faster.
Baggie Ice Cream Supplies: 2 zip-lock sandwich bags 1 gallon zip-lock bag ½ cup half and half ½ teaspoon vanilla 1 Tablespoon sugar Add the sugar, vanilla and half and half to a sandwich size bag Carefully squeeze out most of the air and zip the top Place the bag into the second sandwich bag and zip the top Put the double bag in the gallon size bag. Add the iced and sprinkle the salt on top Carefully squeeze out most of the air and zip the top to close it Vigorously shake the bag for about 8-10 minutes, taking turns Take the baggie in the middle out, Carefully open the baggie and put the ice cream into a bowl to eat ENJOY
Salt lowers the freezing temperature of water so when you add the salt to the bag of ice, the freezing point drops below 32 degrees. In order to melt, it needs to absorb heat and so the salt-ice mixture grabs the heat from the cream and air around it and drops below 32 degrees. Because the cream does not have added salt, its freezing point remains the same, and begins to freeze
