Take a Candle Carousel for a Spin

Science Fair Project Idea

Scientific Method

Have you ever ridden on a carousel, or a merry-go-round, at an amusement park? On a carousel, you usually get to take a seat on a wooden horse or other animal that spins around and around as the carousel is turned on and powered by electricity. Another smaller type of carousel that people can have in their homes is a candle carousel, which is powered by heat from candles. In this science project, you will get to make your own candle carousel and investigate how the spinning speed of the… Read more

Not only can wind move objects with air, you can do it, too—as long as the objects are not too heavy! You can, for example blow on something—or you can… Read more
