"What happens to paint when we add water?"
Predictions:
- The paint colour will go thinner and lighter
- The paint will go runnier.
First we painted a strip with red paint.
Than we added 25mls of water and stirred the paint to paint the next strip. We kept going like this until all the strips were done.

Can you see what happened to the paint?
We found out that some strips were almost the same but mostly that we were right about the paint going thinner and lighter.
Heres a hint...think about the model that Joy showed us with the rice (that were the water molecules) and the blocks (which were the paint molecules).
Fletcher asked the question: What is the right amount of water to create paint that will spread enough and colour the paper?
Good question...I wonder how we could find out?
"wow" that looks cool because I did not know all of that stuff
ReplyDeleteIt got lighter
ReplyDeleteCause there was a heap of water in with the paint witch made it lighter.
ReplyDeleteWe stained our back steps. We started to run out of stain. So we watered it down. When we applied it - it looked dark. As it dried it looked slightly less dark. But over time the watered down section has worn away much more than the thicker areas. We recommend against watering down paint and stain - especially when you are half way through.
