Advanced Activities

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.
An Ice Lens Almost every optical instrument, from binoculars to cameras to eyeglasses, contains lenses that were made by opticians. You can discover basic lens-making techniques in this activity.
Diffraction Between Wax Blocks Diffraction is the bending of a wave around an obstacle. Try this activity out to see what happens when we add wax blocks to a ripple tank.
Interference in a Ripple Tank What happens when waves collide? Try out this activity to see how waves in a ripple tank behave when they cross paths.
Perspectives: Powers of 10 In this activity, learners complete a series of drawing activities to explore scale and powers of 10. Use this activity to introduce learners to how scientists use specialized tools to study small things.
Shimmering Lenses In this activity, learners use Jell-O to explore lenses and different angles of light entry.
Total Internal Reflection When light hits an interface between two different media, it can behave in two different ways. Typically, the light partially refracts (bends) and partially reflects. The refractive index of the material is what determines how fast light travels in a material. Light travels about one and a third times faster in air than in water. Learn about total internal reflection in this activity.
