Big Question:  How do we design a 

Why does a swing slow down and stop?

To continue our investigation on swings we paired up and each got a different length string and created a class graph from our results. This was a great visual that really solidified our understanding of pendulums, and how the length of the string is the determining factor of the speed of the pendulum. We also continued our investigation on energy in motion. To see what happened to the energy in the pendulums, we used a simulation to factor in potential, kinetic energy, and air resistance. We also got the chance to design a playground surface using an experiment with an egg. Our basis was to create a surface soft enough for an egg to not crack after being dropped. We were given the option between four different materials to mix and make a landing for the gg. My partner and I chose a combination of sand and hay. We put the sand on the bottom and hay on top, and we were able to successfully drop it and keep the egg safe from 1 meter on our first attempt. After we attempted two meters, and due to human error/interference it was not successful.
