Forces

Forces--those that push and pull on objects--are a critical concept in the elementary science classroom. For learners to truly understand this physics topic, they need to see forces in action. This well-designed book takes an up-close look at forces, exploring essential themes such as gravity, magnetism, and friction, through at-level and engaging text that leads into a related high-interest activity, such as making balloon rockets and hovercrafts as well as testing whether objects sink or float. Colorful images accompany both the main information and the step-by-step instructions.
