DAY 103

GOALS: SWBAT...

● Be able to describe the relationship between energy and temperature. 

● Be able to describe in words and pictures how energy is transferred between two objects at different temperatures and explain when and why this process stops. 

● Be able to plan an investigation to produce data to support a model of how the system of a hot object and a cold object will change with time. 

● Use Google Drawing tools

WARM-UP

1. Describe how a thermometer works, using high school level academic language, and including a description of what's happening at the ATOMIC LEVEL. Look it up if you need to 

2. Go to Schoology. Open 103B: Temperature and Energy Student Handout

CLASSWORK

103A: Review CW/HW from yesterday

Review Phases and Changes Lab

103B: Temperature & Energy Activity

    1. Read the Handout on Schoology

    2. https://phet.colorado.edu/sims/html/energy-forms-and-changes/latest/energy-forms-and-changes_en.html

HOMEWORK

1. 103B: Temperature and Energy Student Handout due Sunday 11:59pm

    Need help? Video! —> https://youtu.be/ngwVGkvaPME

2. Lab 2: Crash Barrier due Monday 11:59pm

Goals:

1. Define heat

2. Define temperature in relation to KE

3. Explain how a thermometer works

WARM-UP

1. Imagine a Fourth of July sparkler. Does it hurt if a spark hits you? Why/why not?

2. What about walking across a bed of hot coals. People do it. How? Does it hurt?

3. One more. Can you move your hand through the flame from a lighter or match? Does that hurt?

CLASSWORK

103A: Thermodynamics Conceptions

Which of these statements are correct?

1. Metals attract, hold, or absorb cold.

2. Conductors conduct heat more slowly than insulators.

3. Insulators conduct heat fast and heat leaves so insulators don’t feel hot.

4. Insulators absorb/trap heat.

5. Wool warms things up

6. There are two types of heat: hot heat and cold heat.

7. Heat is a material substance.

8. Temperature is an extensive quantity. (meaning, it depends on the amount of substance)

9. Temperature of boiling water can exceed 100 °C during boiling.

10. Temperature is a measure of heat.

103B: Understanding Heat and Temperature

Think back to our Phases & Changes Lab from Friday.

• 1. What happened to the ice? Why?

  2. Why did some water leave it’s liquid state, and convert to a gas (to make steam) and then turn back into a liquid to make condensation?

To answer these questions, we need to understand the concepts of temperature, and heat.

Our activity to do that is here: https://docs.google.com/document/d/1Xq2agFM48XOy4XieMn_ldA1bqstgPhXZjoDTnOnuBLQ/edit?usp=sharing
