An excellent activity awaits your young scientists! In it, learners are invited to explore the world of pulleys, levers, and planes; simple machines that make lifting heavy things much, much easier. They watch video, and engage in...

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...

Seventeen pages of material leave you well-prepared to carry out this lesson on levers and pulleys. Photos and diagrams make the instructions clear; resource links provide additional information. The missing aspects of this teacher's...

Young scholars study the three different types of levers and develop a simple machine. In this levers and simple machines lesson, students look at different types of levers, and experiment with a ruler and a marshmallow to determine how...

Students investigate how levers help to lift heavy loads. They view and discuss examples of levers, explore various websites, experiment with the levers brought to the class, and watch the video for the book "Mike Mulligan and His Steam...

In this levers instructional activity, 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.

In this levers worksheet, 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.

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.

In this lever worksheet, students read and do the 8 detailed steps in an investigation about levers. Students answer 2 essay questions and record their data on a chart.

In this machines worksheet, students draw a "Rube Goldberg" style machine which uses 3 different types of simple machines to complete one task.

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...

Fourth graders choose a simple machine and write about they way they believe it will work. Students experiment, write down procedures used and record observations. They will find a picture of the machine and add it to their report.

Students investigate the lever and the mathematics associated with levers. They determine the conditions necessary to balance a system of forces around a fulcrum.

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.

Third graders investigate levers and the concept of work.
