Title: Discovering the Changes in Saturation in Different Colors While Underwater

Problem Statement: How does the saturation of the colors red, yellow, and blue, compare at depths of 0, 5, 10, and 15 feet?

Method and Materials:

Materials:

- One large boogie board
- One spool of kite string wrapped up marked at 5-foot increments
- One waterproof clipboard
- Laminated sheets (size 81/2 inches by 11 inches) of red, yellow and blue paper
- Duct tape
- One 5 foot long piece of wood
- Two binder rings
- One underwater camera
- One computer with Hyper Studio
- Scuba gear

Method:

1. Take the 5-foot stick and tape it perpendicularly to the clipboard.
2. Tape the waterproof camera on to stick, parallel to the clipboard.
3. Open the binder rings.
4. Take the boogie board and tape the open binder rings 4 inches apart on the back of the boogie board.
5. Put the spool of string in between the binder rings and close the rings.
6. Tie the end of the string to the clipboard. (the final contraption should look like the one below)
7. Take a picture of the three laminated pieces of paper (red, yellow and blue).
8. Put the boogie board and every thing attached to it in the water. The boogie board will float.
9. Pull the clipboard down to 5 feet in the water. You will be able to measure by the markings on the string.
10. Put the red sheet in the clipboard and take a picture.
11. Put the yellow page in the clipboard and take a picture.
12. Put the blue sheet in the clipboard and take a picture.
13. Move clipboard down to 10 feet and repeat steps 10-12.
14. Move clipboard down to 15 feet and repeat steps 10-12.
15. Get the pictures developed and ask the developer not to make any adjustments to the pictures.
16. Take the developed photos and scan them into a computer with Hyper Studio.
17. Open the pictures in Hyper Studio.
18. Using the eye dropper click on the color.
19. Double click on the color that appears next to the eye dropper icon.
20. Click on the HSV Picker.
21. Check the saturation of the color.
22. Record the results.

The experiment should work like this...

 

Hypothesis: We think that the red's saturation will have the most significant decrease, then yellow and lastly blue. See graph and chart below for exact numbers.
