Today we made our class roller coaster. Yesterday, we talked about the differences between rollers and spinners. We figured out that spinners rotate around an axis and rollers rotate around themselves. We also noticed that spinners can rotate in one position, but rollers move from one place to another. Next we got some Styrofoam tracks and we rolled marbles in it. We found out that the starting point had to be higher than the ending point. Then we connected a couple of tracks together and we made hills and guess what? We made loops. Someone came up with the idea of connecting all the tracks and making a roller coaster. Wow! We created many different ways to finally find the one track that the marble would roll all the way to the ending point. Our roller coaster had two loops!
This weekend you can also make your own roller coaster by clicking on the sight below. Have Fun!
