Opposites Attract

Why do some magnets attract while others repel? Scholars use clearly labeled permanent magnets to explore the attractive question. They compare the behavior of like versus opposite poles to find the answer.

Students investigate physics by conducting a science experiment. In this magnetism instructional activity, students define a list of vocabulary terms associated with force and complete a worksheet based on magnet attraction and repel....

Young electrical engineers use balloons, cereal, and PVC pipe to test how positive or negative charged particles can attract or repel each other. First they attract Rice Krispies with a static-charged balloon, and then they use two...

Delve into the differences among solids, liquids, and gases with this PowerPoint. It is both applicable and attractive. Large, colorful diagrams display the molecular arrangement of each state of matter and their properties are arranged...

Whether they pull together or push away from one another, magnets are sure-fire pupil pleasers! Take their study of magnetism to a new level with a fun interactive. Individuals control the polarity of two spheres to observe attractive or...

Students brainstorm background knowledge and any questions they may have about magnetic fields. They investigate the role that William Gilbert had in laying the groundwork for modern experimental science. Students observe magnetic fields...

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?

Like all electricity, static electricity flows at the speed of light, or 186,282 miles/second. The interactive simulation shows how like charges repel like charges and opposites attract. The user can choose either one or two balloons, a...

Young scholars research all the ways people seek their soulmates. The question if opposites attract or those with similar attractions is studied in depth. Compile all the many steps a scientist must often take to answer what looks like a...

Can you get the puck into the goal using only electric charges on the ice? Scholars experiment with electrostatic forces as they determine which charges pull the puck and which repel it. Multiple levels reinforce different related...
