The purpose of this activity is the show how temperature affects the molecule bonds in water. As water heats up, the molecule bonds expand, this is why water travels up the straw when submerged in hot water. When water cools the molecule bonds become smaller, which is what happens when we place the bottle back into cold water. Use this activity as an opportunity to work on the children’s’ observational skills. Ask them to describe what they see in detail. Take note of what they say and look for opportunities to extend the conversation based on what they describe.
