Corn Starch.

What happened when you held it, let it drip, squeezed it, punched it, poked it and scooped it?
When I held it dripped and when I dripped it was like slime and when I punched it turned into a solid when you poke it, it just go through and when I scoped it, it just go out of your hands.
What happened when there was too much water? When there wasn't enough water?
When there was too much water it was just liquid and if there was tool little water it was a solid.
Did the substance change after time?
After some time the water goes out and it turns into corn starch.
How did your hands react to this mixture?
They reacted by feeling very weird
What further inquiry (questions or tests) could you do? What tests could you run next time or which ones did you run today that would provide evidence to your conclusion of whether it is solid or liquid material?
I want to try to see if creating a tower with that is possible.

What materials could you use at home to test the differences between white powders?
Water I just mix water with them and see what happens.
Why is corn starch so special when it is only mixed with water?
It is special because it turns into a solid and a liquid
Is this new material a liquid or a solid? What are the properties of each and how can you determine them?
It is both because it is corn which is a solid and starch which is powder and water which is a liquid.
What are your final thoughts of today's experiment and investigation?
It is so fun and awesome you can play with it so much and there are so many thing you can d

  1. I'm glad that you paid attention to the questions that were on the Grade 6 post, but I would like you to work on elaborating more on your answers. These were very basic and you made many more observations than you expressed here.
