A class created a terrarium using soil, grass seeds, charcoal, gravel, landscaping fabric, and water. They placed their terrariums in the sunlight and gave them water every other day. Every week, the students measured the height of the grass. Create a hypothesis about their terrarium experiment.
Answers will vary. I believe that the grass will grow 4 cm a week.

Ball A: 50 cm in diameter weighs 20 pounds. Ball B: 50 cm in diameter and weights 5 pounds. Both of the balls were dropped off a building 100 feet in the air at the same time. Ball B reached the ground first. Draw a conclusion from this experiment and explain.
My conclusion is that, a lighter ball travels faster in the air because it hit the ground before the heavier ball.
