We also demonstrated the hex nut drop, stick release experiment, and pendulum catch experiment!
We had a great time learning about energy today! First we introduced physics, inertia, gravity, potential energy, kinetic energy, and acceleration using Newton's Beads Experiment! The fountain of beads flowing from the container was a great science demonstration. The science behind Newton's Beads centers around the principle of inertia. According to Isaac, inertia is the tendency of all matter in the universe to remain motionless if not moving, or, if moving, to continue moving until acted on by an outside force. Lifting the container into the air added potential energy (or stored energy to the motionless beads. The tug you gave the beads to start them flowing was all that was needed to overcome gravity and convert the stored energy into kinetic energy (the energy of motion). As the speed of the moving beads increased, you probably notice that the string actually lifted above the rim of the container a little bit. This was due to the inertia of now fast-moving , falling beads. Newton stated that an object will continue moving in the same direction until a large enough force acts on it (the arcing motion of the beads is caused by the downward force of gravity) to change its speed and/or direction. The beads are now falling at a much faster speed than you downward tug. (www.sickscience.com/go/14nb025)

Great job on the website! Looking forward to the upcoming meetings. I learned a lot about energy and solar power. We have great stem teachers and very intelligent kids. I cant wait to learn more and build a solar robot!

Wow! Awesome website! I built my robot yesterday and it turned out great. Thank you for supplying the robots. Also, thank you to the professors and students at ASU.

I had some much fun last year and am having a lot this year to! It is such an appreciation to be apart of it last year and this year. just wanted to say thank you to our stem teacher!
