Mining

Hypothesis:

It what hypothesized that some amounts of ore are more valuable than others. For the cookies, it was predicted that the Smart Choice Chocolate Chip cookie will have more chips, therefore representing more minerals than the Voortmans Chocolate Chunk Cookie.

Materials:

• Cook Tools Tooth Picks
• Voortman Chocolate Chunks cookie
• Smart choice Chocolate Chip cookie
• Brown paper towel
• Ruler (30cm)
• Ziplock large plastic bag
• Text

Experimental Design:

A ruler (cm) was chosen to measure the amount of chocolate in the cookie.

Procedure:

1. A Voortman Cookie was placed onto a brown paper towel.
2. Notes and text were then cleared off the desk.
3. A Cook Tools Tooth Pick was used to pick out pieces of chocolate chips.
4. The chips were then placed aside on another paper towel.
5. Next, the cookie was crushed in search of hidden chips.
6. The final chips were placed aside, as were the left over crumbs in a separate pile.
7. The chips were then placed in a line and measured with a ruler. The results were then recorded.
8. A Smart Choice cookie was then placed on a new paper towel.
9. Steps 3-7 were repeated.

Observations:

It was observed that the Smart Choice cookie had lots of chips; more than the Voortman cookie. The Voortman cookie had more cookie than the Smart Choice.

Results:

Conclusion:

Overall, we discovered that some ores are more valuable than others.

Application:

In reality, an ore can be more valuable than the next. This was shown because the cookie represented the ore, and the chips represented the minerals found inside. One of the cookies had more chips than the other, this proving ores can be more valuable than others.

Questions

• 3 a It is easier to retrieve the cookie from the top because part of the chip is already touching the outside. The toughest place to find the chip is in the middle because it's surrounded by the cookie. It's not as accessible.
• 4 a

  Voortman Chocolate Chunk	1/11 of the cookie is chocolate chips
  Smart Choice Chocolate Chip Cookie	1/8 of the cookie is chocolate chips

• 5 a The second cookie overcomes the first cookie because the second has a greater amount of chips than the first cookie.
• 6 a The second cookie, the Smart Choice Cookie has more chocolate in it. (difference of 7 cm)
• 7 a The results support the hypothesis because the Smart Choice cookie has more chips than the first. (If it were an ore, it would have more minerals than that of the first ore).
• 7 b Two chocolate chip cookies were mined instead of one, to show the difference of chips (ore) found in two different spots.
• 7 c The investigation was a fair test between the two cookies because each brand represents a different mining area. Every brand is unique so it relates to the different ores.

Making Connections

• 1a Geologists should take several samples because if one piece of ore has less purity, another ore sample may have more purity. Or incidentally, you might have obtained a different mineral. If they did take more samples, they would be able to detect the different mineral, and collect the right samples instead.
• 1 b Geologists should vary the distance when taking samples, because more pure ore might not be found in the same area, but could be found far apart.
• 2 a The Smart Choice Cookie would have the greater value because it has more grams of chocolate.
• 2 b The Smart Choice Cookie is more valuable because there are more chocolate chips in it.
• 3 a No, it wasn't easier for us to obtain the chips from either cookie.
• 3 bIf it is very difficult to obtain, it may get damaged if it is forced out. It could get scratched or scrape up, which would be decreasing the value of the ore.

Exploring:

A wire gauze would be fixed in place halfway through a tub acting as a sifter. The cookies would then be placed on top of the wire gauze. Next, the tub would be filled with luke-warm water. Placing the cookie in a tub of luke-warm water will let the crumbs turn to mush, while the chocolate stays intact. The tub would then be shaken, so it would sift the cookie crumbs and they would fall to the bottom, leaving only the chips on top.
