Experimenting with Magnets

Have you ever wondered what roundworms are like? Or what they don't like? Explore the sensory preferences of C. elegans through this controlled chemotaxis experiment. Biology class members brainstorm what substances might attract—or...

Everyone loves playing with magnets and iron filings. Here, young scientists first observe and then participate in an activity demonstrating magnetic fields. After completing their observations, they apply this knowledge...

Learners explore the properties of magnets by designing a device that can move as far as possible using only magnets to move it, and design a machine that will stay in motion for the greatest period of time.

Teach your class about magnets and electromagnets with a reading passage. After reading the passage, learners respond to five related questions.

A thorough investigation of magnetic levitation; this activity has four parts. First, physical scientists play with a wooden dowel and three disc magnets to review polarity and repelling action. Then they experiment with...

Here is a very good lesson on magnets, magnetism, and magnitic fields that is chock full of great activities for you to implement with your young scientists. Learners discover the properties of magnets, look at the forces of attraction...

Six simple images pull your class into magnets. Most of the pictures show magnetic fields as revealed by iron filings. Concepts are explained in print along the bottom of each slide and include magnetic force, force fields, poles,...

In this magnetism activity, students investigate why magnets attract certain objects and how the magnets can attract or repel each other by participating in a classroom activity. Students will observe, question, and investigate how the...

Have your young scientists create electroscopes and conduct an experiment using various types of materials (some conductors, some insulators). What happens to the electroscope when each object is passed through its plastic pieces?

Students investigate solar energy and color. In this solar energy lesson, students assess the benefits of solar energy. Students discover that solar energy is attracted to darker colors and conduct an experiment using colored...
