Task: Modeling Temperature Change Part 1: Conducting Heat with Spoons 1. Describe a time when you had a hot drink that had to go in a specific cup. ● What was the drink? ● What kind of cup did it go into? ● Why did the drink have to go in that kind of cup? 2. Imagine a bowl of hot water that has three spoons. One spoon is made of metal, one is made of wood, and one is made of plastic. If the spoons are allowed to sit in the hot water for five minutes, which spoon do you think will be warmest? Explain your answer. ● Prediction: I think the spoon made of out ___________ will be the warmest because… Except where otherwise noted, this work developed as part of the ClimeTime initiative is licensed under a Creative Commons Attribution License.

The circles in the models below represent particles of water. What can we add to the model to show the difference in the amount of thermal energy the particles have in room temperature compared to boiling water?

The At Time = 0 model shows the thermal energy of the water particles using “motion lines”. 1. Add “motion lines” to the particles in the spoon in the At Time = 0 model to show the relative thermal energy of the metal particles. 2. Draw arrows in this model to show the direction of thermal energy transfer.

How many units of thermal energy would the water particles have after 5 minutes? How many units of thermal energy would the spoon particles have after 5 minutes? Color in the energy bars beneath the model to show your answer. 2. Add “motion lines” to the water particles and the spoon particles in the model to show the relative thermal energy of the particles. 3. Draw arrows in this model to show the direction of heat transfer.

The Comparing Materials model shows particle models of wood and metal. Based on your knowledge of thermal energy transfer, why does the metal spoon heat up faster than the wood spoon? 2. Draw or describe a particle model of the plastic in the plastic spoon. Explain your model.
