Chemistry for Kids: Fishing for Ice

This Fishing for Ice project shows kids how chemistry works in everyday life. Get your kids interested in STEM → science, technology, engineering, and math with nothing more than ice, water, salt and string. You'll lower the freezing point of water and catch some ice!

Science Lab Supplies

• Free printable lab notebook with full instructions (available in the free printable library)

The lab book contains three easy science experiments for kids and contains areas to record your notes and observations. You can print it on card stock or plain paper and assemble it with ring clips or staples. It would be perfect for a science party.

 

Fishing for Ice Supplies

• Water
• A clear jar or glass
• Table salt, 1-2 tsp
• Food coloring (optional)
• String

 

Fishing for Ice Experiment Instructions

• Stir a drop or two of food coloring into the salt to create colored salt crystals. You can skip this step, but it makes the string easier to see.

 

• Fill the jar about three quarters full with water.
• Add a few ice cubes.
• Sprinkle eat ice cube with a few pinches of salt.

 

• Lay the string across the ice cube and salt.

 

• Wait for 1-2 minutes.
• Carefully lift the string out of the water and see how many ice cubes are attached.

 

Experiment Follow-Up

Complete the lab notes section of the printable lab notebook (available in the free printable library) with your kids. Have them record their predictions and observations. Try the experiment with more ice then less ice. Record the results.
