In this activity, learners examine fingerprints. Learners leave a hidden print on a surface and then make their own print detecting powder from graphite (found in pencils).

In this activity, learners investigate the behavior of magnets. Learners create a "wonder wand" with a magnet so they can move a skater around.

In this electrochemistry activity, learners will explore two examples of electroplating.

In this activity, learners investigate various appliances and electronics, discovering how much energy each uses and how much carbon dioxide (CO2) is released to produce that energy.

In this activity, learners explore how various energy sources can be used to cause a turbine to rotate.

In this activity, learners build a simple qualitative conductivity tester with a battery, bulb and foil.

In this activity, learners simulate the process of DNA fingerprinting by using electricity to separate colored dyes.

In this activity on page 10 of the PDF, learners detect the amount of energy that can flow through a sodium chloride electrolyte solution with a light sensor.

In this activity about magnetism (page 17 of the pdf), learners experiment with magnets, exploring the concept of diamagnetic materials by seeing how a grape reacts to a magnetic field.

Learners observe an electrochemical cell constructed from a small jar containing zinc and copper strips immersed in separate solutions. The strips are connected to a motor that turns a small fan.

In this electrochemistry activity, young learners and adult helpers create a battery from a potato to run a clock.

In this activity, young learners investigate magnets. Learners discover that some magnets are stronger than others and that magnets have north and south poles.

In this activity, learners discover how a piece of fruit can act as an electrolyte, conducting electricity between two different metals.

In this physics activity (page 8 of the PDF), learners will make their very own working compass.

In this physics activity (page 4 of the PDF), learners will explore how similar magnetic poles repel one another. They will rely on linear induction to race magnets around a simple course.

In this activity, learners make an electromagnet motor to demonstrate the most basic method of changing electrical energy into mechanical energy.

In this physics activity (page 6 of the PDF), learners will explore how static electricity affects surrounding objects.

In this activity, learners make a model of a power plant that uses steam. Learners use simple materials like foil, a tin can, and a pot of water to model a geothermal power plant.

Learners build a simple one-cell battery and use an ammeter to measure the flow of current.

In this activity, learners create an electrical circuit and investigate how some dissolved substances conduct electricity.
