All The Colours Of The Rainbow

This week my son & I have been working on learning colours & making rainbows. Here are 2 of the science/ sensory activities we did:

Make a Rainbow

What you need:

-Shallow dish

-1 cup of whole milk

-Red, blue & yellow food colouring

-Liquid Dish Soap

What to do:

-Pour 1 cup of milk into the bowl. 

-Add 3 drops of red food colouring to one edge of the bowl 

-1/3 of the way away, add 3 drops of blue food colouring

- 1/3 of the way away add 3 drops of yellow don't mix or jiggle the bowl. 

-Squeeze a drop of dish soap in the center of the bowl and watch what happens!

What happens: The dish soap does not mix with the milk. Instead it floats on top and spreads over the surface. As it spreads, it grabs the food colour we dropped into it. Where the colours meet, they combine to form new colours.

 My son loved this activity. He kept saying "Wow!" & his eyes were big. He was so amazed watching the colours.

Muffin Tin Mixing

What you need:

-Muffin tin

-Food Colouring

-Medicine dropper

-Water

What to do:

-Fill the muffin tin 3/4 full of water

-Add food colouring to the water 

(I made one red, one blue & one yellow. The rest I didn't add colouring to)

-Using the dropper mix different colours together

 As you can see K loved this activity too. I worried it might be a bit too hard for a 17 month old but he figured out how to use the dropper & we mixed colours together. K loved watching the colours change & learned the words "een" (green) & red. We did this for nearly an hour which is crazy considering his usual time span for any activity is a max. of 2 minutes on any given day.

Just be warned, there will most likely be tears when you try & pack it away & you'll probably have to do it over & over & OVER again. Oh..& careful with the blue colouring....I may have inadvertently coloured K's hands green. Just getting in the spirit of St. Patricks day right?
