states of matter- bag bomb! LIQUID - Pour 1/4 cup of warm water into a ziploc bag. Next, add 1/2 cup of vinegar to the water (food coloring optional). SOLID - In a tissue, dump 3 tsp. of baking soda. Fold the tissue up like a square.Zip it up, let go of the pouch, and watch the bag expand - GAS! Soon the bag will look like a giant bubble. Hold it up and look what's happening inside, an acid-base reaction, creating CO2!
This would be a beneficial activity for our lesson plan because it describes the atom spacing for each state of matter. This goes with our science part of the lesson, which will then build up to how money is made and the different states of matter it goes through.
