Today with Mr. McWiz we worked on an experiment to see if a car travels further with more or less dry ice in the “tank”. I got to help design the entire experiment.
We looked at the straw diameter as a variable and I proved the smaller diameter produced more thrust to launch the car. Then we looked at the quantity of dry ice. I got to use the triple beam balance to determine the weight of the dry ice. I made sure things like water temperature and amount of water were controlled. Mommy played a science secretary and kept great records.
After the fun and experiment, I wanted to mix soap, dry ice, water and food coloring. I love the tactile hands on reward at the end of a long morning of thinking scientifically,
What a fun science lesson as always with Mr. McWiz!
