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
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.
Curated OER
Exploring Levers
Students examine the parts of a lever system and their functions. In this simple machines lesson students study the different classes of levers and what they are used for.

Levers - An Interactive Lesson
Seventh graders identify the different parts of a lever. In this physics lesson, 7th graders draw a lever and label the different parts. They use the interactive board to create their own lever.
Curated OER
Three Classes of Levers
Eighth graders research the three classes of levers and create a Power Point presentation showcasing the fulcrum, effort arm, and resistance arm in each class. They then write a paper explaining real life applications of the levers.
Curated OER
The Gear Game
Students discuss that the conservatin of energy states that the energy imput must equal the energy output. They then figure out how can a machine help you to perform task otherwise considered impossible? Students discuss the six simple...
Cornell University
Catapult
Studying levers couldn't be more exciting! Learners build their own catapults and test the results as they make adjustments to the fulcrum. They compete against other groups to create the most accurate apparatus.
Curated OER
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
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.
Curated OER
Who's the Frog Jumping Champion?
Students use a simple machine (a lever) to launch a plastic frog. students determine who is able to make their frog "jump" the farthest and graph the results.
Curated OER
It's So Simple
Students use basic materials to create four simple machines. In this introduction to simple machines lesson, students are given four different scenarios that require a simple machine in order to solve. The students use devices such as a...
