The lever lifter
Explorers (Foundation), mission E5 Grab & Lift, lesson 2 of 6.
Hook
Can a tiny push lift a heavy thing? Let’s move the pivot and see.
Fair test
Put the pivot near the load, then near your hand. When is lifting easiest?
Bonus challenge
Lift a teacher’s mug (empty!) with just one finger.
The build
Lever Lifter: A long beam on a movable pivot with a cup at one end. Slide the pivot and feel the push get easier or harder.
