Centripetal Force

I told my fourth grade astronomers that when I think of space, I think of force, motion, energy, and balance. Centripetal force is the force that keeps an object moving in a circular path. Satellites in orbit around a planet is an example of this force, but there are many examples in everyday life. We performed several investigations to see this force in action. Friction and gravity were also at play.

Snowflakes

My daughter lives in Detroit. She captured this snowflake as it hit her car window. All snowflakes, which are made from ice crystals, have six sides. Each snowflake is unique.

Scientists of all ages will enjoy cutting their own snowflakes on this fun site:  Click here.
