The cost of manufacturing is vital when acquiring nonrenewable and renewable raw assets. Engineers concentrate on each the science and economics behind buying natural sources. Engineers do value-profit analyses to make accountable decisions about how to obtain the sources. They give the impression of being to maximise income while also contemplating how the atmosphere- the close by air, land and water-could be impacted via mining by (hopefully) selecting the least destructive mining technique. For example, floor mining and underground mining have very distinction costs and ways that they influence the lithosphere.

Before the Activity
– Make copies of the Cookie Mining Worksheet, which is an easy profit 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 prices: Before mining timing starts:
Land Cost
1 cookie = $1,200
Land space = squares on graph paper (partial squares = 1 full square)
Tools Cost (choose not less than 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 every
“Dirty” chip = chips which have cookie stays on them = $200 each
Partial chip (should be combined to type quantity of ore in a single chip) = $a hundred every
Labor Cost (Time)
Ongoing mining operation = $50 per minute
Land Reclamation Cost
Original land (cookie) = $30 per square
Additional land (circles) made during reclamation = $50 per square
With the scholars
1. Ask the class the pre-activity questions, as described in the Assessment part.
2. Present to the category the Introduction/Motivation content to kick-off the activity.
3. Give every scholar a bit of graph paper and one chocolate chip cookie.

1. With the category, undergo the cookie mining reference data. Have students decide on their instruments, realizing that instruments are one cost of manufacturing that can determine into their remaining profits.
2. Before timing begins, have college students hint their cookies on the graph paper and count the squares inside.
3. Place the cookie back contained in the circle. Explain that from this point on the cookie will not be touched with their arms. Direct students to begin mining while noticing the clock in order to maintain monitor of how a lot time the entire class spends at cookie mining (labor value tracked by minutes).
4. Have students dig out as many chocolate chips as they can using solely their instruments.
5. After college students have mined their cookies, they begin reclamation through the use of only their tools.
6. Once as many of the remaining cookie items are positioned again inside the circle, have college students draw additional circles across the crumbs that are not placed inside the principle cookie circle.
7. Tell the scholars: When all mining and reclamation is full and mold steel you’re able to sell your chocolate ore, arrange them in such a approach that they may be simply counted, tool steel tube and elevate your hand. For each pupil, notice the quantity of minutes they spent cookie mining.
Profit-loss statement: Have students fill out the worksheet, which guides them by tabulating the costs of land (cookie), mining tools, seamless steel tube supply labor/time, mining operations, and land reclamation, as well as calculating the mining income and profit (net income).
Cost-benefit evaluation: Discuss with college students the variations in prices amongst their peers together with how their cookies are examples of different sorts of mining. For instance surface mining by which students destroy the cookie in the method vs. underground mining in which the cookie (land) stays largely intact.
