Experiments are a hands-on way to teach elementary school students about scientific concepts. This winter, celebrate the colder season by incorporating ice into your experiments, whether it’s to teach how matter changes or how ice forms. Here are a few simple and fun experiments to try with your students.
3 Ice Experiments to Try in Science Class
1. How to Grow Ice
Teach your younger students how to make ice grow. Place a bottle of water in the freezer for about two and a half hours to get it cold enough without completely freezing. Fill a small plastic tub or cup with ice. When you slowly pour the cold water into the cup, the ice will grow taller.
2. Conduct an Ice Excavation
Fill a set of plastic cups with water and drop a small plastic toy in each. Store them in the freezer until they are completely frozen. The aim of the experiment is to excavate the figures from the ice with different melting methods. You can test this with variables like rock salt, sugar, and warm water.
3. Melt Colorful Ice
Use watercolors for another experiment to demonstrate how ice melts. Fill big trays or bowls with water and store them in the freezer. Once frozen, place them on a tray in the center of the table. Allow your students to add salt to begin the melting process, then add food coloring or liquid watercolors to the ice as it melts to create a swirl of mesmerizing hues.
