 Electricity
Burn with Electricity trailer
Watch trailer.
Burning Things with Electricity and Oil Lamps -- Students discover how certain materials glow when electricity flows through them. They then try burning different kinds of oils to see which one makes the best oil lamp. This relates to electricity, voltage, amperage, resistance, heat, light, combustion, and materials. Difficulty: High
Capacitors trailer
Watch trailer.
Capacitors (Teen class) -- Students experiment with several different sizes of capacitors to discover how electrical charge can be stored and released, and what happens if you short out a capacitor. This relates to electricity, voltage, amperage, resistance, heat, capacitors, leyden jars, static electricity, and storing charge. Difficulty: Medium
Foam Cutters trailer
Watch trailer.
Foam Cutters -- Students build a simple device that uses electricity to cut patterns in foam. This relates to electricity, voltage, amperage, resistance, heat, and materials. Difficulty: High
Fog and Static trailer
Watch trailer.
Fog & Static Electricity -- This lesson is a variation of our "Dry Ice" lesson that also includes part of our "Static Electricity" lesson. Students explore the properties of dry ice, including making fog. They also get to "magically" disperse the fog with static electricity by simply pointing their finger at it. This relates to solids, liquids, gases, sublimation, condensation, dew point, freezing point, vibrations, clouds, greenhouse effect, respiration, and static electricity. Difficulty: High
Hand Crank trailer
Watch trailer.
Hand Crank Electricity -- Students make electricity with their own muscle power and use it to run motors, fans, and doorbells. This relates to electricity, magnetism, energy, electromagnets, torque, vibrations, and sound. Difficulty: High
Static Electricity trailer
Watch trailer.
Static Electricity -- Students learn about thunder, lightning, and electrons. They discover how to separate a mixture of salt and pepper, lightning safety, and with one hair-raising experience, they discover the nature of static electricity. This relates to weather, lightning safety, electrons, positive and negative charges, voltage, lightning bolts, and cloud formation. Difficulty: High. (You can present an Easy version of this lesson by omitting the Van de Graaf generator section.)
