Hot molecules move fast and cold molecules move slow.- Ethan E.
When water gets hot enough, it starts to steam and it boils because the molecules are moving fast.- Najlah, Robert, and Khelis
If you have 2 cups of the same temperature water and combine it, the temperature stays the same.- Destiny
If you have 2 beakers of different temperature water and combine them, the temperature will be in between the 2 temperatures.- Amare
If there is a small surface area, heat that is inside the cup will stay hot longer because the all the molecules are trying to get out and it will take time because it is not wide.- Madison and Julius
If there is a lot of surface area the molecules can get out faster because there is a wide space. The liquid that is inside will get colder.- Aeisha and Tomi
If you want something to stay hot or warm, you should use the best insulator.- Alaya
An insulator is a material that you use to cover the cup so the drink can stay hot. Insulators stop the hot molecules from traveling.- Eva, Geah, and Elijah M.
When you start with an ice cube and you don't want it to melt, you can use an insulator. The insulator will block the heat from coming inside the cold ice cube.- Elisabeth and Kerrisa
