The kids were amazed when I mixed two clear liquids together to make this bouncy ball. The most amazing part? After we left it for a day it flattened out and took the shape of the bag it was in. So it had the properties of a solid and a liquid. Everyone wanted to take this one home.
We also spent a lot of time exploring the properties of different white powders. We are using six different powders: salt, sugar, powdered sugar, corn starch, plaster, and baking soda. We'll be using these same powders to do different experiments. The important things we did this week was describing each of them in a way to tell them apart from all the others. We also mixed a little water and vinegar in each to see what happened. Make sure to check back to see what else we do with our six white powders.
When I was showing the kids how to use a hand lens they laughed because I looked like I had a huge eye when I was using it the wrong way. So Timothy wanted to give it a try and use them as glasses.
We have also been working on writing a how to paper. Our topic, How to Blow a Bubble. I can't wait to show you the end product for this project. The kids have been writing and sharing with each other. We should be able to wrap this up next week for you to see.
STUDENTS: I wasn't at school Thursday when you mixed each powder with water and vinegar. I would like for you to tell me about what you did and what reaction you remember the most. Make sure to write at least 3 sentences for this response.
