Learners test solutions of water, sugar, salt, and hydrochloric acid for electrical conductivity. They immerse leads from a lighting device (a battery pack connected to an LED) into each solution.

In this activity, learners compare and contrast different forms of luminescence by observing how chemiluminescence, phosphorescence, and fluorescence produce or emit light.

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.

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

In this activity, learners explore the principles of magnetism by observing how various materials interact with magnets and superconductors.

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.

Learners are challenged to create solutions that conduct electricity and make a buzzer buzz (or an LED light up).
