All of them created experiments and learned about different types of reactions.

Eric lighting a student built light bulb. The filament is graphite from a pencil.
Thanks Uncle Chris for the opportunity.
Mr. Dempsey has Stephen in discovery and I have him in science. Last year he was given the opportunity to work on a 20% time project with Don and Melissa. During this time he created fishing lures. Which then turned into an online business. Right now he is working on a new bait. He designed a fish using tinkercad.com a free web based design tool.
In this picture there was warping of the plastic and the clamp that he used crushed the mold. The real story behind this was the conversations afterwards:
Stephen: Yeah, it was really weird. It cooled at the two ends but not in the middle.
Me: Why do you think that was the case?
Stephen: Well its thinner there and its away from the pouring source.
Me: What are the molds normally made out of?
Stephen: Metal normally. That's why I need a cnc machine.
Me: What are you going to do next?
Stephen: Well I think we need to print the fish out. Then I can make a plaster of paris mold from it.
Failure didn't stop him. It gave him answers. It directed him to new solutions.

Yesterday and today we set up several chemical reactions. Students were looking for:
A color change
A temperature change
A gas evolving
A precipitate forming
Bromethyl Blue and Carbon Dioxide- color change

Today we talked about the difference between physical and chemical changes. Kids first did a free sort and then a guided sort.

I cut up a piece of paper into paper dolls. Physical
I then burned them. Chemical

It's amazing to see all these kids making.
Trebuchet- in case we get attacked by gnats. Which has a good possibility of happening in my room.
