The teamwork was amazing today! We compared nonrenewable to renewable energy and then broke into teams to explore the different types of renewable energy. Each team became an expert on their topic and presented it to the group by creating a poster! Way to go S.T.E.M club members!
Thank you to Mrs. Stoops and Dean Baker for brining a hot air balloon to Jamaica! The S.T.E.M. club got a special presentation and members were able ask questions and learn all about the science behind hot air balloons. The fog made the experience even more magical!
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)
We also demonstrated the hex nut drop, stick release experiment, and pendulum catch experiment! |
