Fossils!

Coal = ancient trees & plants

Oil/Natural Gas = tiny marine animals


2. Where do they form?

Deep underground = sediments buried with many layers, which caused heat & pressure

Allowed remains to fossilize

Coal = ancient swamps, now mountainous areasOil/Gas = off shore/ in pockets of sedimentary rocks

3. Name one advantage and one disadvantage of using fossil fuels to produce energy.

Do Now 3. Name one advantage and one disadvantage of

using fossil fuels to produce energy.

+ traditional, we know how to use them

+ abundant

+ cheap (compared to the cost of installing new and renewable technologies)

Do Now 3. Name one advantage and one disadvantage of using

fossil fuels to produce energy.

- causes air pollution

- hurts environment when drilling for resource

Turn to your neighbor & give examples of this negative effect on environment

GN Expectation

• Heads Up

• Follow along with the notes

• Raise hand for questions

• Silently Listening

Political Connection!COAL FORMATION1. Ancient trees and plants died in swamps and sank to the bottom and formed peat.

2. Over millions of years sand, clay and other sediment covered the peat, forming sedimentary rock.

3. Pressure from the rock squeezed out the water. Over time it fossilized and turned into coal.

Political Connection!OIL AND NATURAL GAS FORMATION1. Animals in ocean died and sink to sea floor. Remains become covered in sediment.

2. As layers of sediment settled, pressure and heat turned the remains into oil and gas.

3. As earth’s surface changed, pockets of oil and natural gas became trapped in the rock.

Political Connection!OIL AND NATURAL GAS FORMATION

•Mining is used to get the coal used to burn coal in power plants. Mining is also used to get the uranium used to make nuclear energy.

Political Connection!OIL AND NATURAL GAS FORMATION

•As a result of mining, acids are released into the water supply. This can harm plants and animals.

•Methane is released. Methane is a greenhouse gas (more on this in a few days!)

Political Connection!OIL AND NATURAL GAS FORMATION•Strip mining, or surface mining of coal completely eliminates existing vegetation, destroys the genetic soil profile, displaces or destroys wildlife and habitat, degrades air quality, alters current land uses, and to some extent permanently changes the general topography of the area mined

Political Connection!OIL AND NATURAL GAS

FORMATION•Soil removal from the area to be surface mined alters or destroys many natural soil characteristics, and may reduce its productivity for agriculture or biodiversity.

Political Connection!OIL AND NATURAL GAS

FORMATION• After mining is over, the company must complete the process of reclamation. Reclamation is returning the land to its original condition. This includes the material replacement (making the land LOOK the same), as well as replacing vegetation and the type of soil on top.

Political Connection!COOKIE MINING Lab Today, you will be a coal miner.

Your goal is to make the most profit possible.

This means you must minimize costs, while getting the most coal possible out of your mine.

• STEP 1: Question How can coal miners be profitable while minimizing the

effect on the environment? • This is a hands-on activity to help you understand how

mining affects the environmentThe parts:1. Research 2. Decision making3. Data collection via observations4. Cost analysis 5. Evaluation 6. RERUN

• STEP 2: ResearchUse your guided notes & partner to answer 1 & 21.Outline how coal is formed.2. Describe the process of reclamation.

• STEP 2: Research3. Why is reclamation important?

Mining has many negative effects on the environment. It is our job as miners to fix our impact.

• STEP 2: Research4. Who enforces reclamation?State & federal government regulate mining

companies. If it does not look the same- fines are mandated.

This is incompliance with the federal government’s “Surface Mining Control and

Reclamation Act of 1977.”

Lets look @ procedure

• Read for thirty seconds• Turn and summarize with partner

Demonstration• So we know exactly what to do in this lab activity,

we will have two students be volunteers and we will walk them through the procedure.

• Each student is expected to be following along in the procedure

• Expectations:– Listening quietly– Reading procedure– Raise hand for questions

Expectations

1. Stay seated- safety is important

2. Raise your hand if you have a question

3. Talk with your neighbors quietly

4. If you eat your cookie then you will get a zero for the lab and a phone call home

What should this classroom look like during this lab activity?

Land Acquisition • Montana CANDY Cookies -- $3;

• Pennsylvania CHUNKY CHIP cookies -- $5;

• Kentucky SOFT & CHEWY -- $7

• STEP 3: Hypothesis If choose _____________ type of cookie, then I

predict my profit will be high and my costs of reclamation will be low

Related to procedure:Choose a cookie (land) – Costs represents how easy

the coal is to mine$3 - Montana (Candy Chip)$5 - Pennsylvania (Big Chunk)$7 - Kentucky (Soft ‘n Chewy)

Calculating CostAnswer the following questions

• How much did your land cost? _________

• How much did your equipment cost? ____

• How much did you labor cost? _________

• How much did the government charge you for penalties? _________

• *Add these costs together to get your overall cost = _________

Equipment costs• Round toothpick (number) x $4 = $____• Paper clip x $6= $_____• Total equipment costs $________

While you are waiting to get your equipment, write down three observations about your cookie.

Do not begin mining until instructed to do so

We will get our cookies in groups• First = candy chip • Second = chunky• Third = chewyWhen you come up you need to get your suppliesLimit of 3 toothpicks and 2 paper clips

Return to your seat & read procedure

do NOT begin mining

Observations• Place your cookie on the graph paper.

• Trace around your mine so you know how big your mine is at the beginning.

Observations• Make 3 observations, describe what your

mine looks like before mining

–EXAMPLE: Candy chip cookie looks rigid, 4 observable chips, crumbly texture, bridle

Mining/Excavation costs (chip removal)• Number of minutes ______x $1 = $____• Total excavation costs $_____________

ONCE FINISHED MINING- make 3 observations, describe what your mine looks like after mining:

Example: Crumbly, messy, small pieces, larger area, quarter craved out, chips missing, broken, chipped, flaked

Using observations, describe what your mine looks like after mining:

Example: Crumbly, messy, small pieces, larger area, quarter craved out, chips missing, broken, chipped, flaked

Calculate ProfitProfit: Mining valuation

Number of whole chips mined __ x $2 = ___

Total profit $_____________________

RECLAIMATIONAfter the mining is over you must return the land to

its original condition. The land must look the same, and you must replant all of the vegetation (plants, trees, etc.) that are removed in the mining process.

You have 1 minute to reclaim your land. The government will fine you if your land is not returned to its

original position. You will be fined $4 for every square outside your original circle that has cookie in it. Make it look like it did before you started!

AND NO HANDS!!!!

RECLAIMATIONYou have 1 minute to reclaim your land. The government will fine you if your land is not returned to

its original position. You will be fined $4 for every square outside your original circle that has cookie in it. Make it look like it did before you started!

AND NO HANDS!!!!

Make 3 observation, describe what your mine looks like after

reclaiming the land

• Example: Closer to original state, still lots of pieces, not one whole, more mountainous, chunks missing from side, not one whole circle, takes up larger area than before

Calculating ProfitAnswer the following questions

• How many chips did you mine? _________

• How much money did you make from mining? ________

Calculating Overall ProfitAnswer the following questions

• Subtract Profit from Costs = ________

• STEP 3: Hypothesis If choose _____________ type of cookie, then I

predict my profit will be high and my costs of reclamation will be low

Were you profitable??

Clean Up – Stay Seated• You may now EAT the cookie

• I need all crumbs & chips picked up! – You are 1 of 90 students in this room all day

• There will be 2 helpers coming with trash bags

• Toothpicks & paper clips must be thrown away in the trash

• We are not leaving until this room is picked up! “LEAVE NO TRACE”

What should the classroom look like...

• During a lab?• During partner work?

What should the classroom look like?

• Everyone facing the board• Only 2 students per table• Stay seated (safety)• Talking quietly with peers near you

Analysis Questions• Must answer in COMPLETE SENTENCES for full credit

• Begin working on questions while clean up is happening

• Stay seated

• Talking quietly

Example of complete sentences-

1. My mine was very profitable because I spent a lot of money on my land.

2. If I were to do it again I would buy a paper clip, rather than just toothpicks

Conclusion Paragraph • I will help you with this• NO Talking• Listening & raising hands

RERUN• Recall what you did! • What was your PROCEDURE?• What physical ACTIONS did you do?

EX- I chose ______ cookie to mine for chocolate chips

RERUN• Explain your purpose• Connect to OBJECTIVE + Energy

EX- I acted as a coal miner today so I can see the difficulty of mining coal

RERUN• Results• What was your hypothesis??

EX- I can accept my hypothesis because the I made more profit than I had costs.

RERUN• Uncertainity • Error• When did you not follow the procedure word for

work?EX- A potential error in my experiment could be when

we...
