DAY 98
Due to a last minute notification from administration, I need to adjust the curriculum, and postpone the beginning of the thermodynamics unit until Tuesday.
If you missed the exam yesterday, you'll need to take it now.
WARM-UP
1. We spent the past four weeks (hopefully) increasing your understanding of momentum and collisions
2. What activity and/or concept you learned stands out the most?
3. On a scale of 0 to 4, rate your knowledge of momentum prior to starting the unit
4. On a scale of 0 to 4, rate your knowledge of momentum right now
5. If you didn't complete the warm-up from Day 97, do it today
CLASSWORK
1. 098A: Momentum Post-Learning Knowledge Inventory
- The Inventory is on Schoology.
- There are 14 questions.
- At the end of the period, we will go over the answers, and assess your results.
2. 097B: Continue working on your Crash Barrier Lab
- the template is on schoology.
- add title, purpose, procedure, etc.
- we will work on data analysis tomorrow in class
HOMEWORK
If you didn't complete the warm-up from Day 97, do it now.
Essential Question: What is Heat?
WARM-UP 98
Don't look up answers. At this point, there is no wrong answer.
Read the instructions listed in classwork 101A. Make the graphic organizer, then answer the first five questions to the best of your ability.
CLASSWORK
98A: Knowledge Inventory
Make a four column organizer with the following columns (see board for example)
This will take about 60 lines of paper - about 3 pages.
Number, copy, and answer the questions below in your organizer
Rate your understanding of each concept, from 1 (no understanding) to 4 (mastery understanding)
Remember, don't look up the terms or questions for the knowledge inventory. We what to know what YOU know.
| Pre-Learning answer |Rate| Post-Learning |Rate|
1. What is heat? (2 lines)
2. What is temperature? (2 lines)
3. Give three examples of things with thermal energy (2 lines)
4. If thermal energy is continuously added to a solid object, describe the changes in that object over time. (3 lines)
5. Does ice have thermal energy? (2 lines)
6. Why is it relatively safe to walk across hot coals, often called “fire walking”? (2 lines)
7. How, and in what units, is temperature measured? (2 lines)
8. How, and in what units, is heat measured? (2 lines)
9. How does a refrigerator remove thermal energy from your food? (3 lines)
10. Describe the First Law of Thermodynamics (2 lines)
11. Describe the Second Law of Thermodynamics (2 lines)
12. Compare and contrast a heat pump and a refrigerator. (3 lines)
13. Describe how thermal energy can be removed from a cold object and given to a warm object. (4 lines)
14. Describe how a thermometer works and what it measures. (3 lines)
15. Describe what effects the amount of thermal energy an object has. (3 lines)
16. When thermal energy is removed from an object at that material’s condensing or freezing point what will happen to the average kinetic energy of
its particles? Explain. (4 lines)
17. What is entropy? (2 lines)
18. How does the phase that an object is in relate to its level of entropy? (3 lines)
19. List each of the six (6) phase changes and describe them. (6 lines)
20. List each of the six (6) phase changes and determine if they release or absorb energy. (6 lines)
98B: Does Thermal Energy Transfer?
Read over the Launch Lab on page 326/958. You can use the slider bar to move quickly, or the arrows to move slowly. The magnifying glass zooms.
Complete the task. Write your answers in your notebook
Learning at Home (HW)
If necessary, complete 98A and B. Remember, don't look up the terms or questions for the knowledge inventory. We what to know what YOU know.
ESSENTIAL QUESTION: Momentum - Is It Conserved?
Goals: SWBAT...
1. solve a variety of momentum problems
2. ask questions when help is needed
3. work together effectively
Warm-Up 98 (5min):
Solve the following:
A 5,000 kg railroad car moving at 5 m/s collides into a stationary car with a mass of 45,000kg. If they couple together after the collision, what will be their combined velocity immediately after impact?
