Mixing the Primary Colours
Junior and Senior Infants enjoyed exploring what happens when you mix the primary colours (red, yellow and blue). We used six glasses of water, tissue and red, blue and yellow food dye to conduct our experiment. We put the red, blue and yellow food dye into three glasses of water and placed another three glasses of water between each of these primary colours. Some of the children rolled up kitchen towel and placed them in the glasses. We left the experiment to work its magic throughout the day and we observed the colour mixing and changes that took place. The children discovered that when you mix the primary colours together, they create the secondary colours (orange, green and purple).
- A clean 16 ounce plastic soda bottle
- 1/2 cup hydrogen peroxide liquid (Ms. South was in charge of this 🙂 )
- 1 Tablespoon (one packet) of dry yeast
- 3 Tablespoons of warm water
- Liquid dish washing soap
- Food coloring
- Small cup
- Safety goggles
What we did!
- Put on safety goggles while Ms. South carefully poured the hydrogen peroxide into the bottle.
- Add 8 drops of yellow food coloring into the bottle.
- Add about 1 tablespoon of liquid dish soap into the bottle and swish the bottle around a bit to mix it.
- In a separate small cup, combine the warm water and the yeast together and mix for about 30 seconds.
- Pour the yeast water mixture into the bottle (a funnel helps here) and watch the foaminess begin!
