with Sally Zeiner
Working with marbles on smooth and rough surfaces, we explored the concepts of mass, inertia, and friction in class this week. Mass, on earth, is how much something weighs. We learned that inertia is like wanting to keep playing Legos rather than being interrupted to do our school work. Friction acts on a soccer ball when it rolls across a grassy field. Once we discussed and understood these concepts, we conducted experiments and recorded our observations.
We tested the large and small marbles on the smooth table top, a towel, and a bath mat. We also did the final "just for fun" experiment -- hitting the marbles against each other.

Please discuss the results with your child, and review the material on pages 46-48 together, writing up the final experiment together at home.
Have a great week!
