These and other
fun activities await you in the four lessons that are included here. Each
lesson includes Read Abouts, Hands-on Activities, and Experiments to help
you master each topic.
Read Abouts
are non-fiction articles about people or scientific ideas about light. Look
for the Before, During, and After Reading Helps along the way.
Hands-on
Activities show you how to make cool scientific stuff (like a pinhole
camera) and play around with it to learn new things.
Experiments
give you the chance to be a real scientist and conduct some of the same
investigations that geniuses (such as Thomas Edison and Lewis Latimer)
used to invent things we use every day (such as light bulbs).
 When
you're finished learning about the science, technology, math, and history
of light, you'll be ready to put your knowledge to work with the GE
Lighting Audit (GELA). GELA will help you and your classmates find
out how much your school is spending to light your classroom, cafeteria,
gym—your whole school building. It will also show how you and your
parents, friends, teachers, and school administrators can work together
to save energy and reduce the cost of lighting your school.
Hmm… maybe you could save enough for new computers or books or field
trips or….
