1. Unit 2: Energy Conservation and Transfer Day 1 Focus: energy introduction 10-16-17
On a sticky note, write down a word that comes to mind when you hear the word “energy”. Bring the sticky note up and place it on the dry-erase board.

2. Plan for the Day ***Begin Unit 2 Energy -Discussion -Notes -Video
-Group activity

3. Homework
“Resources and World Trade” reading passage and worksheet

4. Essential Question: page 1–COPY WHAT IS IN PARENTHESES: what are some implications (future consequences) of depleting (using up) our natural resources?

5. engage:
Let’s look at the words you came up with when you hear the word “energy” and see if we can categorize them.

6. Energy is the ability to do work. There are different forms of energy:
Kinetic
Potential
Mechanical
Chemical
Thermal
Electrical
Nuclear
Gravitational
Light/sound

7. In this unit, we will focus on natural resources that are used for making electricity (electrical energy)…or energy resources.
Why do you think it is important to study about energy resources? Why do they matter in our everyday lives?

9. 1. Energy resources Energy: any source of usable power/electricity.
What are these sources?
Fossil fuels
Nuclear
Solar
Wind
Water (Hydroelectric)
Geothermal
Biomass
Hydrogen fuel cells

10. 1. Energy resource
Def. -any __________ of usable ________________/ __________________________.
A.D. 1 –examples:
___________________
Fossil fuels
Wind
Geothermal
Biomass
____________ fuel cells

11. There are 2 categories of natural/energy resources.
Renewable
Nonrenewable
A natural resource that CANNOT be replaced at the same rate at which it is consumed.
A natural resource that CAN be replaced at or near the same rate at which it is consumed.

12. Let’s see what prior knowledge you have about energy resources by sorting them.
../Unit 2 Energy th Science/renewable and nonrenewable energy sort.notebook

13. 2. Renewable
Def. -A natural resource that CAN BE REPLACED at about the same rate at which it is consumed.
A.D. 1- Simply put…the Earth will NOT RUN OUT of it . but we still have to practice CONSERVATION with some of them.
A.D. 2 – they are:
1. SOLAR
2. WATER/HYDROELECTRIC
3. WIND
4. BIOMASS
5. GEOTHERMAL
6. HYDROGEN FUEL CELLS

14. 2. Renewable
Def. -A natural resource that ______ ____ _________ at the same rate at which it is consumed (used).
A.D. 1- Simply put…the Earth will ____ _____ _____ of it . but we still have to practice _______________________ with some of them.
A.D. 2 – they are: 1. 2. 3. 4. 5. 6.

15. 3. Nonrenewable
Def. -A natural resource that CANNOT be replaced at the same rate at which it is consumed.
A.D 1 - Simply put…once you use it, you lose it….for millions of years. SO, we must practice conservation.
A.D. 2 - Modern societies are dependent on some of these and will have difficulty functioning without them.
A.D. 3 – They are:
1. Coal, oil (petroleum), natural gas AKA Fossil Fuels
2. Uranium AKA Nuclear

16. 3. Nonrenewable
Def. -A natural resource that ____________ ____ ____________ at the same rate at which it is consumed.
A.D 1 - Simply put…once you use it, you ______ ____….for millions of years. SO, we ________ practice conservation.
A.D. 2 - Modern societies are _____________ on some of these and will have difficulty functioning without them.
A.D. 3 – They are: 1. 2.

17. What energy sources do we Use in the U.S.?
Predictions?
What do you notice?
What problems do you perceive?
Let’s fill in your notes.

18. **Why should we be concerned about this?**
4. U.S. Energy Consumption
A.D. 1 – Percentage of energy that comes from renewable resources?__________ Which do we use in the greatest amount? _____________
A.D Percentage of energy that comes from nonrenewable resources? __________ Which do we use in the greatest amount? _____________
**Why should we be concerned about this?**
____________________________________________________________________________________________________
10%
hydroelectric
90%
Petroleum/oil
Nonrenewables, once depleted (used up), will be GONE! We are most dependent on them.

19. **Why should we be concerned about this?**
4. U.S. Energy Consumption
A.D. 1 – Percentage of energy that comes from renewable resources?__________ Which do we use in the greatest amount? _____________
A.D Percentage of energy that comes from nonrenewable resources? __________ Which do we use in the greatest amount? _____________

20. How has the human population changed?
Why do you suppose developing (3rd world) countries have a faster population growth?
At this rate, what will happen to the human population in the future? Think about this one!
what do you think the quality of life will be for people who live on Earth 200 years from now?
Supply and Demand?

21. What about north Carolina???
Let’s see what energy sources are used by us in Harrisburg, NC and the rest of the US!

25. What do you think about this cartoon?

28. North Korea's invisibility cloak is due to mandatory power cuts at night, part of the country's struggle to conserve its precious energy.
the Soviet Union has limited N.K. access to inexpensive, Communist- approved fuel.
Limited/no trade with other countries also limits their energy availability. They are almost self- sufficient in energy.
Have Coal and Hydroelectric
Import small amount of oil

29. Why are there no lights above India?

30. Where do you see a lot of electricity use?
Why do these areas generate more electricity?

31. Why are we studying this unit?
At the current rate we are using (consuming)energy, we won’t have enough resources to support our growing population of people! We are reaching our carrying capacity.

32. 5. Carrying Capacity
Defin. -The maximum number of organisms that can be supported by the resources of an environment.
Organisms = humans
The environment = Earth
Ex. If your mom makes dinner for your family of five people, and you invite 3 friends over without asking her (so 8 people), you will have exceeded the carrying capacity for dinner. There would not be enough dinner for everyone to eat and be full.

33. More Realistically….
Our carrying capacity should increase as we …..improve technology and conservation efforts.
But are we doing enough?
As carrying capacity increases, what happens to human population? What does the carrying capacity appear to be doing to human population in this graph?

34. What happens to the population when the carrying capacity is exceeded?
What happens to the carrying capacity?

35. 5. Carrying Capacity (cont.)
A.d.1 -Carrying capacity generally keeps the population in check.
A.d.2 -If population exceeds (goes over) the carrying capacity, the population will decline rapidly, then slowly rebound/increase.
A.d. 3 -If population exceeds carrying capacity, the carrying capacity will decline/decrease, then slowly rebound/increase.

36. 5. Carrying Capacity
Def. -The maximum number of _______________ that can be ________________ by the ________________ of an environment.
A.D. 1-Carrying capacity generally keeps the population ____________________________________.
A.D. 2 -If population exceeds (goes over) the carrying capacity, the population will ___________________________________________________________, then____________________________________________________________.
A.D. 3 -If population exceeds carrying capacity, the carrying capacity will ____________________________________________________________, then____________________________________________________________.

37. Sounds great, right???? Everything will eventually straighten itself out, right????
What problem do you see?

38. Problems our future may hold if we don’t change what we do today:
Resource depletion – using up our resources
pollution, acid rain, deforestation
Food shortages
Increases in prices
Poor water and air quality
Poor Health
Wars over resources (food, water, medicine, space)
Climate change
Extinction (plant, animal and possibly human)

39. If you were elected president of the United States….
What new laws would you put in place (no more than 3) to try and prevent energy problems we may face in the future?
Work with your group
Write down the laws AND tell why/how they will help.
