In this section you will find experiments that will help you understand the physics of light impress your friends with your new ability to manipulate light and color using nothing but a few gumballs and a shoebox. Best of all, you will probably get to make a big mess all in the name of science.
Who knows you may even make a new scientific discovery of your own and get to wear your hair like Albert Einstein.
These experiments explore the basic concepts of light and color. They will help you understand how light travels and how color and light interact with each other to produce amazing results. Activities in this section are suitable for scientists five and older.
Light bends when traveling through various substances, can be scattered depending on what it hits, and the colors white and black are not as simple as black and white. The experiments in this section are recommended for scientists 10 and older.
You are ready to take it to the next level. You have mastered all the other experiments and need a challenge. Try your hand at these experiments, recommended for scientists 15 and above.
Hands-On Optics (HOO) is an education program that brings together optics experts, teachers and parents to enlighten students about science, technology and the field of optics.
Activity of the Moment
We know that when light reflects off a plane mirror, the image appears left/right reversed. Once
you bring in another mirror and change the angle between them, it is much harder to keep track
of what orientation each image will have. In this activity, students will use the letter R – a letter
which is neither horizontally nor vertically symmetric. When the letter R is reflected several
times, this lack of symmetry helps us figure out how it has been reflected.
