In Science class, we just finished up a unit on balance and motion. We learning how to balance a pencil on the sharpened tip, using a counterweight. We took cardboard crayfish and balanced them in a variety of different ways. We created zoomers and spinners. We built roller coasters - both physical and virtual. But by far the most popular activities were the ones involving tops. Students loved creating, building and spinning tops!
Vocabulary we learned during this unit includes: counterweight, counterbalance, air resistance, stable, slope and rotational motion.
