Students explore motions, forces and magnetism. They investigate magnetism as a force and examine the construction of a magnet. Students examine the force that magnetism produces.

Learners study the chemistry of ammonium nitrate and consider the advantages and disadvantages of this compound. They compare different fertilizers and calculate the molar mass and percent nitrogen in the different fertilizers.

Students list four ways to identify trees. For this tree identification instructional activity, students use tree identification techniques such as leafs, bark, wood grain, soil type, and climate to create tables and graphs.

Students investigate the effect that fins have on rocket flight. They construct two paper rockets that they can launch by blowing through a straw, one with fins and one with wings, and observe and record the results of the rocket flights.

Young scholars familiarize themselves with the proper names of muscles and bones and where they are located.

Students explore air through guided discovery. In this air lesson, students will observe three demonstrations about air. They will answer leading questions as they observe how air displaces and takes up space, how air has weight, and how...

Student measure mass to discover how pennies have changed in their composition. In this measurement lesson, 8th graders investigate through an open-ended problem to discover how the US pennies composition changed in the 1980's.

Fifth graders construct their own electromagnet out of copper and nails. They discover what objects could be used for magnets. Finally, 5th graders discuss how electric currents are formed.

Fifth graders are introduced to the concept of circuits and how electricity works. In groups, they design their own subdivision with houses in which they have inside and outside light sources. To end the lesson plan, they make the...

In this physics/engineering activity students physically make an arch by pushing on each other with arms outstretched over head. As long as the pair of students balance each other's force their arch will stand, although it will be weak....

This guide focuses on everyday substances and how we can change their properties by adding heat or cold, physically manipulating them, or mixing them together.

A Java applet on vector addition. Users drag two or more vectors to be added together. Clicking a button shows the resultant of the vectors.

An experiment to test what happens to water when salt or sugar is added and it is then frozen into ice cubes. Students also explore the ice's physical properties by rubbing cubes on sandpaper and dropping a heavy object on each type.
