This week we are exploring the forces of motion. We talked about gravity and tried to jump as high as we could to see how gravity feels when we “fall” back down. We played with our marble run, which has sections that allow the marbles to fall straight down and observed that they go really fast. Then there are the other pieces that make the marble go around in a circle, a squiggly line, make something spin, and even do a loop!
We observed that the marbles can travel at different speeds through those pieces of the marble run, which is very interesting. This is called friction. We wondered what else can cause friction to slow down a marble. Since we have paint readily available, we decided to test out how the paint would affect the motion of the marble, and turn this experiment into art!
Stay tuned for tomorrow’s extension: applying magnetic force to marble painting!
