The price of production is vital when obtaining nonrenewable and renewable raw assets. Engineers concentrate on each the science and economics behind buying natural sources. Engineers do price-benefit analyses to make accountable selections about how to acquire the resources. They give the impression of being to maximize earnings whereas additionally considering how the surroundings- the nearby air, land and water-is perhaps impacted by way of mining by (hopefully) choosing the least destructive mining methodology. For instance, floor mining and underground mining have very difference costs and ways in which they impression the lithosphere.
Before the Activity
– Make copies of the Cookie Mining Worksheet, which is an easy revenue and loss statement template.- Write the Cookie Mining Reference Sheet info (also below) on the classroom board OR make copies as a handout.
Cookie Mining Reference Information
Startup costs: Before mining timing starts:
Land Cost
1 cookie = $1,200
Land area = squares on graph paper (partial squares = 1 full square)
Tools Cost (select at the least 2)
1 paperclip = $500
1 spherical toothpick = $300
1 flat toothpick = $one hundred
After mining timing ends:
Revenue from Sale of Chocolate Ore
Chips that fall off of the graph paper = “lost”
Whole, clear chip = $500 each
“Dirty” chip = chips which have cookie remains on them = $200 every
Partial chip (should be combined to kind quantity of ore in a single chip) = $a hundred each
Labor Cost (Time)
Ongoing mining operation = $50 per minute
Land Reclamation Cost
Original land (cookie) = $30 per sq.
Additional land (circles) made during reclamation = $50 per sq.
With the scholars
1. Ask the category the pre-exercise questions, as described in the Assessment section.
2. Present to the category the Introduction/Motivation content to kick-off the activity.
3. Give every student a chunk of graph paper and one chocolate chip cookie.

1. With the class, go through the cookie mining reference data. Have students determine on their tools, mechanical steel realizing that tools are one value of production that may figure into their closing income.
2. Before timing starts, have college students trace their cookies on the graph paper and count the squares inside.
3. If you have any kind of inquiries about where as well as the way to make use of mechanical structural steel [darcvigilante.site], mechanical steel you possibly can contact us from our own page. Place the cookie back inside the circle. Explain that from this level on the cookie will not be touched with their fingers. Direct students to start out mining while noticing the clock so as to maintain monitor of how much time the whole class spends at cookie mining (labor cost tracked by minutes).
4. Have college students dig out as many chocolate chips as they can utilizing only their instruments.
5. After college students have mined their cookies, they start reclamation through the use of solely their instruments.
6. Once as lots of the remaining cookie items are positioned back contained in the circle, steel pipe have college students draw extra circles around the crumbs that are not placed inside the primary cookie circle.
7. Tell the students: When all mining and reclamation is complete and you are able to promote your chocolate ore, arrange them in such a way that they could also be simply counted, and increase your hand. For every pupil, note the amount of minutes they spent cookie mining.
Profit-loss statement: Have students fill out the worksheet, which guides them through tabulating the costs of land (cookie), mining equipment, labor/time, mining operations, and land reclamation, as well as calculating the mining revenue and profit (net income).
Cost-benefit analysis: Discuss with college students the variations in costs among their friends along with how their cookies are examples of different sorts of mining. For example surface mining wherein students destroy the cookie in the process vs. underground mining by which the cookie (land) remains largely intact.
8. Conclude by way of a class dialogue, asking students the put up-activity questions, as supplied in the Assessment part.
