Grade 4 forces and motion
Pushes and pulls, simple machines, magnets and building strong structures. Here is what we have for Grade 4.
Lessons
Grades K–5Science
Build It, Launch It
Egg drops, paper planes and balloon rockets, done properly at home. Three engineering challenges where kids build, test, fix and explain the pushes and pulls behind what happened.
Grades 4–5Science
Forces at Work: Gravity, Resistance, Levers and Pulleys
Do heavy things really fall faster? Why are fast swimmers shaped like torpedoes? How can a small push lift a big load? Three hands-on lessons on gravity, air and water resistance, friction, levers and pulleys, measured in newtons with homemade and simple tools.
