Students investigate the magnitude of Earth's magnetic field using PASCO. In this physics lesson, students describe the features of the magnetosphere. They explain how atmosphere layers protect the Earth.

Clever! Earth science learners construct a model of a planet containing a magnetic core. The planet, Terrabagga, is made out of a paper grocery bag, magnets, a dead D battery, and rubber bands. Pictures of each step of the construction...

Fifth graders, in groups, create paper bag "globes", complete with magnetic poles. They use compasses to determine and label various locations (N. and S. Poles, Prime Meridian, Equator, etc.) and finish it by drawing in the continents...

Physical or earth science pupils prepare a magnetometer by inducing magnetism into a pair of straight pins. As the pins hang from a thread, they can be used to detect the magnetic field or poles of a magnet. They could also be used as a...

Third graders solve a cryptogram by decoding a message written with wingdings.  In this decoding lesson, 3rd graders solve a message related to magnetism.  Students have notes about magnets once they've finished.

This interesting science lesson is about the compass. Students make a compass out of a magnet, sewing needle, cork, and a glass dish. The lesson includes both a pre and post-test for the students to take, and some very good links to...

Review the difference between rocks and minerals using this resource. Learners identify and investigate the physical properties of these objects. They create a Venn diagram to compare and contrast types of rocks. This is a motivating way...

Students create a paper model to illustrate sea-floor spreading.

Students build their own compass following a given procedure. In this technology lesson, students explain how a compass is used in navigation. They trace the history of its development.

Students construct their own galvanometer. In this physics lesson, students explain how it is used to detect electric current. They conduct an experiment to measure how much electricity flows through the circuit.

In this clock construction instructional activity, students use a pencil, compass, and sun clock diagram to construct a homemade sun clock. A very interesting instructional activity on combining images with text.

Learners explore the different parts of the Cassini spacecraft. In this space science lesson, students create a model of the spacecraft using food products. They compare and contrast their model with the real one and evaluate its...

Learners explore why Antarctica is so important to the planet. They investigate the physical characteristics. Students create their own unique treaty of governance for Antarctica and discuss how laws are enforced in Antarctica.

Students work in pairs to construct a simple stereoscope.
