The theme of today was that things in our world basically come in 3 states- solid, liquid and gas. When we add heat or cold, or mix things together, our objects can change. That is what we played with on Chemistry day!
To get their brains going on this morning, I gave them a squiggle, and asked them to turn it into something to do with Science. It was a super quick and easy activity and I loved the results!

Shrinky Dinks!
The favourite activity of the day was making our own Shrinky Dinks.
Milk Art! Another favourite was mixing homogenized milk, food colouring and just a dab of soap on the end of a toothpick. The liquids don't blend, and it creates a colourful kaleidoscope that is continually moving. (Don't stir them - just poke with the toothpick).
Chemical Reactions!
I have some special paper from SteveSpanglerScience that reacts when it comes in contact with a base. I believe it has the spice turmeric in it. When we dipped a Q-tip in a baking soda/ water solution, it turned the paper bright red

| It's hard to tell in the picture, but the difference between the boys and girls in this activity was... interesting! One group was quiet, sitting, drawing nice pictures. The other was making huge messes and haphazardly colouring most of their papers red. But both were totally engaged! |
Ice tunnels!
I tried a few different ways, but the best way we found was to pour rock salt on top of the ice blocks (previously frozen in 500mL yogurt containers), and then add food colouring on top. As the salt melts the ice (by lowering its freezing temperature) it forms tunnels in the ice. Adding the food colouring allows you to see the various tunnels in the ice. Not as much of a "wow factor" as all the other things we did this week, but some kids really enjoyed it. A great lazy afternoon activity to keep 'em busy for a while.
Equal parts soap, paint and a bit of water. Blow bubbles and then place a piece of paper overtop to make a print of the bubbles. We tried the paper underneath, too, which can get really watery and it takes away the bubble prints completely. But if you leave them to dry with the bubbles on top of them, (see pics below) the bubbles will eventually pop and the paint will dry in cool patterns.

| Disclaimer- We were so busy having fun that I forgot to take pictures. I stole this pic from the internet. Ours weren't as dark as this. |
