To test how light rays work.

Aim: To come up with

an experiment to make

a rainbow.

Prediction: I believe this experiment

can go as a sucessful project because

i have seen rainbows in the sky,waterfalls,

and etc..

Equipment:

* A bit of water

* A cup

* 1 sheet of paper

* Sunlight

Fair Test:

We kept the cups,water and paper amount the same.

We changed the sunlight.

Method:

First we filled the cup with the appropriate amount of water

Secondly someone held the cup in front of the sunlight and kept it there so nothing goes wrong.

Finally we put paper ontop of the cup and looked underneath/bottom of the cup and... THERE WAS A RAINBOW!!!!

Results: We saw a rainbow underneath the cup and knew that our scientific experiment was successful.

Conclusion: Light travels in straight lines however when it hits the liquid aka water it bends, which is known as refraction consequently it splits seven different colors which are the colors of the rainbow!
