Engineering Design, Bobsled Activity
My bobsled was supposed to be fast. I had a a material under my bobsled that didn't allow it to slide well so i should have removed that. Also i should have put all the weight in the front instead of the back.
Fantastic Forces
The fantastic forces was very interesting. I liked learning how certain forces cancel out the laws of others. For example F=MA. This also works with pulling a cloth out from under dishes or a glass. The last thing i really enjoyed was when she put a pencil through wood, with enough force. Also, the friction of air is enough to slow things down.
Lightning show
Watching the lighting show i learned that lightning, while can be loud and bright., is actually silent and invisible. We can see this by rubbing a balloon on someone with long hair. Also, during a lighting storm, never just lay down on the ground. Find a grounded place, either a car or a house. To get rid of your electrical charge, touch someone with a negative charge to balance it out.
Archimedian Excogitation
This was very interesting to see how one thing can lead to another. While there was not really any introduction to this, it was still lots of fun to watch it play out and see how all the pool balls need each other in order to keep the next one going.
