polymers and monomer structure

Answer 3

What about floating vs sinking. Using common house hold objects like a rock, penny, small plastic bottle, and anything else you can find. Then drop them into a bucket of water and time how long it takes them to sink. Its easy and you won't have to buy supplies.

Answer 4

put one white flower in a vase with 5 cups of water and one white flower in a vase with 5 cups of water with food coloring (red green blue yellow or any color) for one week.
make sure you take pictures and write a few sentences on what you noticed (since he's only in kindergarten it won't be much)
Make sure you measure the amount of water, minutes in the sunlight, and how long you have been growing them, those will be the controlled variables.
