The Perfect Rainbow Challenge Science 9

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

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!

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.

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. Explanation
