1. Mixing different water: We mixed amounts of water at different temperatures to see what the final temperature would be
Here we predicted it would be the average of the two temperatures if the two amounts were equal
Now doubling the size of one of the amounts, we came up with an equation to predict the final temperature
This graph demonstrates the temperature change of two different amounts of water at different temperatures being mixed together. Since the larger amount had a colder temperature, you can see that the final temperature is closer to the colder temperature
2. Fire bubble: Here we lit a bubble on fire that was filled with gas that originally floated up
As we predicted, the bubble continued up on fire. We did not predict that it would spread to the sides though, which it did.
3. Can conduction: Here we repeated #1, where we took the same amount of water at different temperatures and mixed, but with one inside a can before being placed in the other
The same results occurred with the final temperature being between the two initial ones. The material between them, still conducts the heat. Our picture at the bottom right shows cold water and hot, with hot molecules having 3 tails and cold with 2. Our representation of the final temperature is just to the right, with both molecules having the same amount of tails, 2, the average between both.
4. Heater in mug: Here we placed a water heater in a mug of room temperature for 20 seconds
From here we made several graphs with LoggerPro to demonstrate several different relationships
