1. The Perfect Rainbow Challenge
Science 9

2. Your Challenge
You will use the concept of DENSITY to devise a procedure to get the perfect 4- 5 colour rainbow in a cup

3. Your Supplies Plastic cup Water Sugar Scoopula
Food colouring (5 colours)
You may also use, hot plates, fridge, eyedroppers, beakers etc. Ask and you might receive!

4. Evidence of Inquiry
Define Density and then explain how that relates to the rainbow cup
Write a hypothesis.
Make detailed procedure of EXACTLY what you do for each trial i.e. masses, volumes, heating cooling, methods of application.
For your FINAL correct trial, you are to create an iMovie TRAILER, comic, slide show, poster etc to show the procedure for PERFECTION!!!!
Take pictures
Piece them together
Add text to show EXACT measurements
WRITE A CONCLUSION THAT EITHER SUPPORTS OF REFUTES YOUR HYPOTHESIS.

5. Hypothesis
A testable proposal used to explain an observation or to predict an outcome of an experiment.
Often written as an if……. Then …… statement
Example
I have observed that mixing colors makes new colors. If I mix red and yellow in equal parts, then I will see orange because the light reflecting to my eye will be a combination of both colors.
