DAY 100

Essential Question: How does thermal energy flow?

Goals:

1. accurately collect data using a thermometer

2. state how increasing the amount of water affects the rate of temperature change

3. state why the temperature of a object changes

WARM-UP 100 (4 min)

Don't look up answers. At this point, there is no wrong answer.

1. What is heat? 

2. What is temperature? 

3. Give three examples of things with thermal energy.

4. If thermal energy is continuously added to a solid object, describe the changes in that object over time. 

5. Does ice have thermal energy?

100B: Does Thermal Energy Transfer? (12 min)

Read over the Launch Lab below.

    - Safety

        - glass

        - water

    - Thermometer

        - from what perspective should you view the thermometer?

        - Use Celsius degrees

Complete the task. Write your answers in your notebook

Exit Questions

1. From what perspective should you measure temperature on a thermometer?

2. If you did this again, but decreased the amount of water in your beaker, how would that change the rate of temperature change?

Learning at Home (HW)

If necessary, complete 100A and B. Remember, don't look up the terms or questions for the knowledge inventory. We what to know what YOU know.
