Experimental Rainbows

I decided to try out a little science experiment with Arlo after seeing the idea float around Pinterest and this captured his attention for an hour – a parenting win!

You will need:

  • Food colouring
  • Bicarbonate of soda
  • Vinegar
  • Baking tray
  • Pipettes

To prepare all you need to do is add a few drops of colouring to each section of the baking tray and then cover with powder. I provided three pipettes with vinegar in a little bowl and only had to demonstrate what to do once.

First of all Arlo was happy to see the bubbles begin to emerge as soon as the vinegar touched the baking soda. I wasn’t quite sure how much I would need so used rather a lot and the colours didn’t appear at first.

As soon as the colours began to emerge Arlo’s interest peaked and this offered a new aspect to the activity – Arlo was using two pipettes at a time to make bigger explosions and find more colours.

It didn’t take too long for Arlo to figure out that the colours could be mixed and this bought us even more time to play with this tray of magic!

I consider this activity as a success HOWEVER … next time we will be doing this outdoors because the smell was extremely overpowering but we need more vinegar to make bigger bubbles! I’ve also heard that adding washing up liquid might create a better effect so we’ll be trying this out too!

Chase the rainbow Scavenger hunt

This is another super simple scavenger hunt, printed from the amazing Twinkle

Arlo really enjoyed hunting for bugs the first time we tried this on our daily exercise. I don’t have many bugs indoors but our home is full of random little objects so I needed a new idea.

Scavenger hunts help develop observational skills and build problem solving skills too. Along side looking for objects this is helping reinforce his knowledge of colours.

This time I laminated the colours work sheet to tick off and then I also created a treasure box – using an old egg carton – dabbing the colours in to the compartments so that any found objects could be saved and then discussed.

We have used this at home with random bits and bobs including buttons and Lego pieces, and also in the garden with flower petals which then inspired another variation to this simple idea.

Arlo always says that his favourite colour is “rainbows” and so we are going to use our daily exercise to chase rainbows and our task is to find something in every colour to bring home.
