Science with Anne G....
Putting bicarb soda on plates, and then mixing the primary colours with vinegar, the children took turns squeezing the dropper to fill it with a vinegar mix before squeezing it onto the bicarb soda.
We watched as the combination mixed and reacted by frothing up before finally settling down. With a primary colour on each plate, we then mixed yellow and red vinegar, then blue and red and finally yellow and blue introducing the children to the secondary colours.
