Here are a few experiments you can try at home! The explanations for the results of each experiment is on the next page.`````
Lab #1 Experimenting with States of Matter
Materials: cornstarch, water, cup, stir stick
Place 15 mL of cornstarch in a cup. Add 30 mL of water and stir well. Place some of the mixture on a table. Touch it with your fingertips. Is it a liquid or a solid?
Lab #2 Experimenting with Physical Changes
Materials: salt, water, cup
Place 30 mL salt in a cup. Add 30 mL of water. Stir until all of the salt is dissolved. Place the cup in a sunny window. After a few days, check on the cup. What was left in the cup?
Lab #3 Experimenting with Chemical Changes
Materials: 30 mL baking soda, 60 mL vinegar, 100 mL water, cup, popcorn kernels.
Mix the vinegar and water together in the cup and add the baking soda. Immediately add 5 popcorn kernels. Observe what happens for the next five minutes.
Lab #4 Experimenting with Chemical Changes 2
Materials: steel wool, vinegar, cup
Place the steel wool in the bottom of a cup. Add 50 mL of vinegar. Wait for 15 minutes. What evidence is there that a chemical change has taken place?
