These couple weeks in science class we’re learning about energy. Today we learned about energy transfers (how energy can change or transfer) and we got to play with toys (yay), but we also had to record in ways how energy transfers (aww). The way we recorded is we got a booklet of pieces of paper with five empty circles that we explain what happens and we connect the circles by one of the eight different types of energy. We got two minutes to play and two minutes to record the information. We had five stations and we rotated from station to station in small groups so the process took roughly 25 minutes.
The domino station is where, well, we got dominos. I’m a big fan of dominos so this was one of my favorite stations. The first thing my partner, Dina, and I did was line up the dominos so that they could knock each other over when we push one domino. We recorded that as motion energy (when the dominos move), gravitational energy (when the dominos fall down), and sound energy (dominos make noise when they fall down).
Another great station was the toy car station. We got mini, multicolored cars (the type that if you pull the backward and let go they run by themselves). I was pretty fun making the cars run into each other and “accidently” making them fly of the table. Dina and I recorded pulling the cars back as elastic energy when we let go of the cars it was motion energy and when they bumped into or fell off of something it was sound energy.
The most annoying, noisy and round toy is the Magic Ball. You might think that is literally “magic” but it is just a ball. But there are a lot of things happening in this white object. You put your fingers on the metal strips and it will make the most annoying sound that you have ever heard and a red light will flicker on and off. This works because there are two batteries in the ball and the metal strips are electrons making a circuit with your body. The battery is connected to RASS (Really Annoying Sound System) and the red light bulb. This could not be possible without energy. When you put your fingers on the metal strips it will make a circuit which is electric energy, then the batteries starts that is chemical energy, RASS turns on, sound energy. And the light turns on, that is Light energy. That is who the “Magic Ball” works.
What is that in the air? Well those things are the frog jumpers. They jump up to 1 foot! Just push the frog and up, up and away! This works because there is a suction cup connected to the frog. On the suction cup you will find a spring, that is because then the frog will jump. But energy is always there. You push the frog down which is Elastic energy, then the frog jumps Motion energy, the frog falls that is gravitational energy!
When you think of a generator you think of a gigantic electric thing. But what we played with was not like that at all!!!! It was a tiny generator. When you turn the handle sound comes out of it but you are also making it move so that means it is Sound and Motion energy. The engine goes on producing heat and electric energy! Then the light bulb goes on, that is light energy.
