Fourth graders learn how six simple machines, from the ramp to the lever to the pulley, make everyday work easier by changing how we push, pull, and lift, and check what they know.
Students will be able to…
Rolling a box up a ramp is easier than lifting it straight up, even to the same height. How do simple machines make everyday work easier?
Project this and answer each question about the six simple machines and how they help — read the explanation after each one.
Tap any phase to open the teacher moves and student actions.
