1. Resource #2: Forests Natural Resource Mini Unit

2. Resource #2: Forests Forests are renewable resources Forests are valuable to hikers, campers, painters, cross-country skiers, etc. Economic Value: supplying building materials, paper, even food (walnuts, maple syrup) and medicine (in some tropical trees) Three types of forest logging methods... (on the next three slides)

3. 1.Selective cutting: harvesting only mature trees, no seedlings required

4. 2.Shelterwood Cutting:clear-cut smaller areas, leaving small patches untouched so the remaining trees can regenerate a more natural forest

5. 3. Clear-cutting: cutting all trees in a large area, new seedlings of a fast-growing tree are planted for future logging

6. Forests: Discussion Which logging method do you think is the best? Why? Selective Cutting Shelterwood Cutting Clear-cutting Consider our Town Hall. Who would prefer the above methods and why?

8. Resource #3: Fish Natural Resource Mini Unit

9. Resource #3: Fish Who? Fish are a renewable resource Where? Most fish are located along the continental shelf (shallow zone of water along the edge of continents) What’s the problem? Worldwide resource depletion because of over-fishing, pollution of fish habitats and commercial fishing in oceans

10. Fishing Technology New technologies allow big international fleets to take enormous hauls. Here is how it is done: –Electronic sonar and GPS to locate fish –Ships cross the area, dragging huge nets (trawling) at the right depth –Usable catch is often cut, packaged and frozen right on board “factory ships” –Ships can remain on ocean for several weeks before returning home

11. Problems? Huge nets take everything (including dolphins, sharks, sea turtles, immature fish, etc.) Results in millions of tonnes of waste every year Fish populations can’t renew themselves because so many young fish are caught Nets destroy sea bottom when dragged

12. Fish: Discussion How is the new fishing technology similar to clear-cutting forests?

14. Resource #4: Minerals Natural Resources Mini Unit Can you name the minerals in the pictures?

15. RECAP: Natural Resources Where we’ve been and where we’re going... 1.Water (renewable and flow) 2.Forests (renewable) 3.Fish (renewable) 4.Minerals (non-renewable) 5.Fossil Fuels (non-renewable) 6.Energy (renewable and flow options)

16. Minerals Fuel Minerals = fossil fuels (oil, coal, natural gas, etc.) Non-Fuel Minerals = metallic minerals (gold, silver, copper, nickel, zinc, etc.)

17. Mineral Production / Mining Canada is among the leading nations of the world in mineral production Gold Rush –B.C. 1856 –Yukon 1898 Igneous Intrusives: magma flows that have intruded into surrounding rock and often contain mineral rich veins of gold, silver, copper and other metals

21. Textbook Exploration Pg. 162 – 164 (class read aloud while creating a class note together - include 3 definitions) Rest of the textbooks are in Ms. Mullins room

22. Fossil Fuels: Video http://www.history.com/topics/oil- industry/videos#black-gold (black gold - oil, 3 mins)http://www.history.com/topics/oil- industry/videos#black-gold Finish early? Start into Resource #6 (longer one).

23. Resource #6: Renewable Energy Natural Resources Mini Unit

24. What is Renewable Energy? Renewable Resource: a resource that can be replaced fairly quickly, such as forests and animals Energy (used for work) can be extracted from: –Non-Renewable Resources: Fuel Minerals / Fossil Fuels (oil, coal, etc.) –Renewable/Flow Resources: Wind, Solar, Hydropower, Geothermal, Biomass Renewable Energy: energy that comes from resources which are continually replenished

25. Five Types of Renewable Energy Can you name the types in the pictures?

26. 1. Wind Summarize how each type works. Choose three key points for each.

27. 2. Solar Summarize how each type works. Choose three key points for each.

28. 3. Hydro 1.A dam blocks water from moving where it wants to naturally 2.Instead, the water flows through a pipe to a turbine, then back out on the other side of the dam 3.Turbines spin by force of water and rotate a generator 4.Generator produces electricity and sends to power lines, bringing electricity to homes and businesses Summarize how each type works. Choose three key points for each.

29. 4. Geothermal 1. The Earth's hot core creates magma and heats the Earth's crust which is made up of rocks and water. 2.A well drilled two miles deep into the Earth's surface captures the rising hot water and steam. 3.The hot steam rises to the surface and pushes a turbine, which rotates a generator. 4.Generator produces electricity and sends it to power lines, which bring electricity to homes and businesses. Summarize how each type works. Choose three key points for each.

30. 5. Biomass 1.Wood scraps, sawdust and crop waste are collected from farms or manufacturing plants 2.The waste is burned to heat water and create steam 3.Steam is sent to a turbine, which spins to power a generator 4.Generator creates electricity and sends to transmission lines Waste produced by cows or other farm animals creates a gas called methane, which can be captured to produce electricity. Summarize how each type works. Choose three key points for each.
