Activities to be prepared

Material preparation: 1. There is a transparent bottle filled with half a bottle of water, and the inside of the bottle cap is coated with red, yellow and blue pigments respectively.

2. Music tapes and red, yellow and blue markers are fixed on plastic baskets respectively.

Experience preparation: familiar with the law of color change.

Activity process
