1) Pass white light through a prism to divide its spectrum and produce a rainbow.
2) Pass light through a convex/concave lens to show the effect.
3) Show how different color surfaces reflect/absorb dirfferent colors of light.
4) Show how light "bends" through different density materials (look at a straw in a glass of water and is appears bent/shifted).
5) Show how fiber optics works by using different density materials and passes light due to density shifts, not reflection.
6) Use a CCD camcorder to show how they "see" the infrared light produced by a TV remote control.
7) Use two pieces of polarized lens (sunglasses or the polarizing filters used in LCD displays) to show how light will not pass through two polarized filters when they're 90 degrees off-axis frem each other.

Get the Young's double slit expt at home using a piece of thin tough card . Carve out two very narrow slits in it , very near each other (about 0.05 of an inch)parallel to each other and see thru these two slits toward a white lamp (preferrably a tube) .You should see beautiful colored fringes ; the interference bands . You may have to do 2/3 trials without cutting your finger and while seeing use the open eye keeping the other eye closed !! good luck . Show it around to your friends and teacher , parents and all.

Well, here's one from my university days.
Try using varios colored fabrics and objects with differently colored lights. This way you can see what colors are absorbed by different objects and which are reflected.
I vaguely recall that our professor used a red rose and a series of red green and blue lights, along with yellow. When they were all on the rose, you could see the entire rose stem, the petals, etc, but when you took certain colors out, the stem disappeared but the petals could be seen, or taking away red, the stem could be seen, but the petals/flower completely disappeared.
This obviously has to be done in an otherwise darkened room. Quite interesting. But you can do it pretty easily with colored lights, and different objects. :)

Youngs double slit experiment. This is classical experiment and only proof we have that the light behaves like wave. Conduct this experiment both in vacuum and in non vacuum. study the result

Use it for a purpose of significant activities like chating and significant replace and communities,apps like issues. do not spend extra time in the back of that. fix a particular time for that. Spend in common words in that diverse time. Later decrease the time for a week days

Try lighting different substaces on fire with focused sunlight. just don't use gas, really bad idea. trust me.
