STEM Experiment: Comparing Different States of Matter

Introduce your child to the fascinating world of matter and its different states with this exciting STEM experiment. Through hands-on exploration, they will learn to understand and compare solids, liquids, and semi-solids using a range of everyday materials and homemade cornstarch quicksand. This experiment is fun, educational, and uses only safe substances.

Ingredients:

• Cornstarch
• Water
• Various solid materials such as stones, plastic toys, fruit, etc.
• Different types of liquids like oil, milk, water, etc.

Instructions:

1. Start with solids: Explain to your child that solids have a definite shape and volume. Let him/her touch and feel the solid materials you're using. Ask what differences they notice between the different solids. Discuss why certain solids can't change their shape.
2. Move onto liquids: Now, explain that liquids take the shape of whatever container they're in, and that they can flow. Have your child pour the liquids you have gathered into different containers and observe how they change shape but not volume.
3. Create cornstarch quicksand: This is essentially a non-Newtonian fluid – a substance that behaves as both a solid and a liquid. Mix 2 cups of cornstarch with 1 cup of water. Let your child touch it and play with it. If they touch it gently, it'll behave like a liquid. But if they hit it hard, it'll feel like a solid. This will help them better understand the diverse states of matter.

This hands-on experiment not only helps children learn about different states of matter but also encourages them to observe and question - key skills in STEM education.
