"Hello, my name is Omar Adahir from group 3H, and the name of the experiment I'll be conducting is "Heat Transfer by Convection". The materials we'll need for this experiment are: a sheet of paper, a skewer, a candle, a needle, a lighter, and modeling clay. First, we'll create a base with the modeling clay and place the skewer with the needle attached, so that the spiral can be placed on it. Next, we'll cut the paper into a spiral shape and place it on the needle. Then, we'll place the candle next to the spiral and light it, and you'll see the effect. In conclusion, this happens because the lit candle heats the air around it. The hot air is less dense than the cold air, so it rises in a convection current. The rising hot air hits the paper spiral, pushing it and making it spin on its axis. And that's my experiment! Thank you for your attention!"
