Experiments with Levers
Students investigate levers. In this simple machine lesson, students study levers and the mechanical advantage of using levers. They will collect data and illustrate their systems for eight different tests.
Curated OER
Levers 1
In this levers worksheet, students follow directions to making levers with a ruler, weights, pennies, and more. Students then see how much force is needed when adding more weights.
Curated OER
Levers 2
In this levers instructional activity, students conduct an experiment on lifting levers including materials such as pennies, stickers, pencils, and weights. Students then answer 2 questions about what they found.
Curated OER
Levers: Machines at home
In this levers worksheet, students try to find levers in their home or class. Students find 10 levers and record them in this levers list.

Simply Machines
In this machines activity, students draw a "Rube Goldberg" style machine which uses 3 different types of simple machines to complete one task.
Curated OER
Levers
Young scholars brainstorm if they think that any lever would use the same amount of paperclips. They break into small groups and use a data sheet as well as a lever, Lego person, fulcrum, and some paperclips and prove what they think by...
Curated OER
Simple Machines/Technology/ Force
Third graders study and define force. They determine that the cause of movement is pushing or pulling which are the types of force used when operating simple machines. They experiment to determine which object requires the most amount of...

Levers: Catapults
Students construct a catapult that shoots a cotton ball at least two meters using Legos, rubber bands, and plastic spoons. They discuss how the catapult works, and identify any problems they had with their experiment.
Curated OER
Torque Me Off
Students investigate the lever and the mathematics associated with levers. They determine the conditions necessary to balance a system of forces around a fulcrum.

Fulcrums in Our Body
Second graders discuss fulcrums and levers and identify at least two fulcrums and levers on their bodies. They also identify fulcrums and levers on animal bodies.
Curated OER
Levers
Students compare and contrast the three different types of levers. In this physics lesson plan, students hypothesize how ancient Egyptians use them to build structures. They construct their own lever after teacher approves their design.
