Week 5

 This week in lab we finished up our swing investigation by looking at a pendulum simulation, and answering related questions. Next we looked at our final investigation question, "How can we design a safe and durable playground surface?" My group created a multi layered base including sand, rubber chunks, straw, sand, and plastic wrap.  We then proceed to drop an egg from 1 meter, which did not break the egg, and then again from 2 meters, which also did not break the egg. 

As we continued the lab , we looked at the forces and energy that were displayed during this activity. This was shown by looking at two eggs that were dropped at identical times. The egg that was on tile cracked within one frame, while the one on the foam side did not crack at all. After this, we watched a video of two cars continuing to run into each other. No matter what they changed or disrupted about the two cars, the circles on front always retracted in equal distances. This is explained by Newton's Third Law, objects exert forces on each other that are equal in magnitude and opposites in directing. We can connect this to chapter 9 of our pressbook as we learned about Newtons Laws of Motion. From this we can recognize what forces are acting on different actions.
