Step into Dirtmeister's Science Lab and help him answer the challenge question: "How can you lift four times your weight?" Learn about levers, make your predictions and then do the experiment.

Step-by-step illustrated instructions for an experiment investigating how a lever works. An explanation of the science involved is given at the end.

This resource details a cooperative learning activity on experimenting with levers. Offers eight different tests students can engage in. A student data sheet is also provided for students to record their findings. This resource is in PDF...

Build a miniature basketball court, and use a spoon lever to shoot balls into the basket. Experiment with different materials to see which one works the best.

This site contains a scientific experiment in which students build a lever by using a wood plank and brick.

Simple machines are devices with few or no moving parts that make work easier, and which people have used to provide mechanical advantage for thousands of years. Students learn about the wedge, wheel and axle, lever, inclined plane,...

In this structured inquiry, students will investigate a catapult system. Having previously explored and identified the variables of the catapult system (length of lever, mass of shot, angle of catapult), students will conduct controlled...

A lesson plan site that contains activities designed to give grades 3 and 4 experiences in using simple machines.

By the end of this project, learners will be familiar with the 6 different simple machines and will be able to identify how these machines are used in products and tools they use on a daily basis. They will investigate how mechanical...

Extensive site for teachers provides some helpful resources that pertain to plant and animal cells. Includes a microscope diagram as well as plant, animal and pond labs. Also contains links to structures and mechanisms, matter and...

This site, in German, offers numerous apps that illustrate common physics principles. Apps are organized into categories: mechanics, oscillations and waves, electrodynamics, optics, thermodynamics, the theory of relativity, physics of...
