My students were doing a Science experiment today. We're looking at chemistry and I found some great action inquiry stuff using M&M's. However, I have peanut allergies in my class so we're using Skittles instead. Today they had to predict whether the colours of the skittles would collide or combine. Most predicted that they would combine but as you see in the pictures they collided. The kids were pretty excited about the results. I had left my camera downstairs (how convenient) so I used my handy dandy iPhone. The pictures aren't as sharp as I'd like but they show the reactions clearly. Oh, the fun!
