Aim: To observe convection in real life.
Equipment: Lighters, Matches, Tea bags, Heatmat,
Steps:
1- Get a tea bag and cut the top off.
2- Tip out the inside of the tea bag.
3- Stand the tea bag up on the heat mat.
4. Carefully light the top off it with the lighter/matches.
5- Watch it float up in the air.
Conclusion: I saw that as soon as the flame got to the bottom of the tea bag, and i watched it convect and increase in size. Convection is when something heats up it floats in the air, and when it cools down it goes back down.
Awesome Paige! Why does it float up when it is hot? what has happened to the particles?
