The second graders learned about balance and different types of motion.They balanced various two and three-dimensional objects and learned the key terms such as counterweight, center of gravity etc. in the process. The students conducted various experiments to observe the effects of mass and friction on speed and motion. For design and construction they made twirly birds to observe how air resistance varies by altering the wing span of the twirly birds. They also built spinning tops and zoomers.
