Hot and Cold Molecule Craft (Available to download for free below) The hot water balloon should get larger as the air expands as it gets warm and the cold water balloon should shrink as the air inside condenses.Īfter the balloon test we used our thermometer to measure the water temperatures and then we wrote the temperature on our Hot and Cold Molucule Craft (See below). We used a pink balloon for the hot water and the blue balloon for the cold water.
Place one in cold water and one in hot water. They may have heard before that hot air rises and cold air sinks, now they can visualize it.įill small balloons with some air. This is because cold water (and air) is more dense compared to regular temperature water and will sink in warmer water. The ice should float and the blue water that melts from the ice cube should sink. Fill a container with room temperature water and place the blue ice inside. Fill an ice tray with the blue water and put it in the freezer until the ice is solid. The blue food coloring should move slower through the water compared to the red food coloring because the water molecules in the hot water have more energy and move faster then the water molecules in the cold water.įill a pitcher with water and add drops of blue food coloring. Technically you could use whatever color food coloring you have but since red and blue help to reinforce the difference in temperatures we used those colors. Have child drop a few drops of red food coloring in the hot bottle and blue food coloring in the cold water and watch (this experiment is very fast so don’t look away). The frozen line should be above the water line because when water freezes it expands because the hydrogen bonds in the water that form are more spread out then when it is in liquid state.įill one tall container with ice cold water and another tall container with hot water (not boiling).
Have children look at the new water lever (ice level). Put them in the freezer until they are completely frozen. Mark the water line with a marker or I used a rubber band because we use our water bottles a lot.

Learn about Hot and Cold Temperature Science ExperimentsīECAUSE ALL ACTIVITIES ARE BETTER WITH A BOOK!Ĭlick photos: Affiliate links to more information on these books we love! ? I think that my favorite activity was watching the food coloring disperse in hot and cold water–such a simple activity and yet so pretty to watch! They were so eager to check everything out and best of all their understanding of temperature grew.
I loved watching my kids try out these science experiments. Each of these activities are super simple to set up, mainly because most of the supplies come straight from your kitchen faucet. We have a free printable activity to go along with all the hands on activities so your little scientists can have fun understanding more about the world around them.
We did 6 different science activities to learn about temperature and the difference between hot and cold.
