Chemical A: A white, powdery, solid (corn starch)
Chemical B: A yellow colored liquid

Oobleck was white and gooey. It was also a physical change since the powder and liquid combined changed it into a solid/liquid goo.

I think that the oobleck was a solid and liquid, it all just mattered on how much liquid was put in it and also where it was. If it was on the table sitting it would turn hard and dry but when u would hold it in your hand you could see that the top of it looked wet so it was a liquid.

Oobleck helped me see how physical change works and also how it could be 2 states at the same time, having both properties of a solid and liquid.

Ammeter 1= 220
Ammeter 2= 220

Bulb 1= 1.2
Bulb 2= 1.1

Battery= 3.0

The current stayed the same in ammeter 1 and 2. The voltage in the bulbs are different by 0.1. The voltage of bulb 1 and 2 combined are different to the batteries voltage by 0.7. The current and voltage change depending on how many ammeters or voltmeters there is.

I learned lots from experimenting with the Van De Graaf. I learned that it was able to bend water and pick up materials. I found it interesting on how we were able to make a human chain and it could shock people.

The combination that worked best was the white plastic stick and fur. We were able to make one full rotation and I learned how friction causes static electricity.
