Curated OER
Using Fulcrums
Students engage in a lesson that concentrates on the use of a lever and fulcrum. They define how a lever is used to lift a load. The lesson has background information to justify it. Students demonstrate how to use the lever while lifting...
Curated OER
Positioning the fulcrum in class one levers
Students explore the relationship between force and the distance of the load from the fulcrum. In this experimental activity students get into groups and make a lever and record the force that is needed to move it, they then try this...

See Saw
Can a mother who weighs five times more than her child really be held in the air on a see saw by the child? A simple simulation demonstrates how this is possible through altering the distance from the fulcrum. Scholars can adjust the...

Secrets of Lost Empires II-Pharaoh's Obelisk
Young scholars identify and analyze how levers work by raising a brick with a shish kebab skewer. Students present their work, explaining what did and did not work, including illustrations of the lever lift from different angles. Young...
Curated OER
Secrets of Lost Empires I
Students investigate how levers can be used to lift objects. They participate in hands-on activities to explore the distance a load is lifted when comparing the amount the lever arm was pushed down. Students discover the how placement...
Curated OER
Work Made Easy
Second graders maneuver placement of the fulcrum on the lever to see how to lift weight most easily. They role-play as archaeologists with the task of lifting a heavy rock from the dig site. They write in science journals about what...
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
Can You Find the Difference?
Students create their own balance to determine a difference in the weight (and composition) of cents made in different years.

Helping Hand
Sometimes we all need a helping hand. Scholars get together to lend a hand in creating an assistive device that must be able to grab a hard-to-reach object. Now that's some help we could all use!
Curated OER
Lifting a Load
Students experiments with levers to determine if the amount of force needed to lift a load is always the same. In this physics lesson plan, students use Lab-Pro data collector as they experiment with the fulcrum placement to measure the...

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.
Curated OER
Make Work Easier!
Pupils work in pairs to design a lever. They conduct experiments using a penny and nickel to explore the uses of a 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.
