Paleontology, Feb 13th, 7th Period

"Okay, today, we're going to practice digging fossils out of rock. Don't worry if you've never done it before- and I suspect that probably none of you have- we'll be doing this exercise at least once more, so I can see your progress. Everyone choose a rock and get to work!"

On the table at the front of the classroom are seven rocks of various sizes, plus hammers, chisels, and brushes.

"And don't forget to hand in your homework as you leave. No presentations today, because let's face it, the assignment was sort of boring."

[ooc: comment in the Discussion thread with whether you took a large, small, medium-sized, whatever, rock, and then whether you managed to free your fossil with no problems, or possibly chipped or broke it.]

Discussion/Assignment!

Work on your fossil here. Or talk to your classmates.

Rory took a small rock and began to meticulously poke at it with her chisel, pausing occasionally to brush at it.

Eventually, she freed what she was pretty sure was a fossil, only chipping it very slightly on one edge.

Perfectionist.

Molly took a large rock and cracked it in half the first time she hit it with the hammer.

"Oops."

A loud cracking sound prompts Tommy to look in Molly's direction.

"'Oops' is right," Tommy says, examining one half of the rock and pointing out the cross section (http://www.geo.ucalgary.ca/~macrae/t_origins/carbbones/dino_bone7.jpeg) of bone. "Do you want to try and get the halves out from the rock? It might be easier now that you can see exactly where the fossil is."

Rose takes a small rock and works at it with her chisel and hammer, pausing occasionally to brush it off.

Janet took a medium rock and worked at it carefully until she freed the fossil. Which she didn't chip. Showoff.

After selecting a larger rock and chipping bits off, Sharon glanced over at Janet's perfection. And huffed before throwing a handful of chips at her fellow student.

Whether her aim was on or not was entirely up to the chips.

Meanwhile, the fossil began to emerge.

Janet snickered at Sharon and tossed a couple of chips of rock back at her. "I've been working on very small sections of the fossil at time," she said. "And being careful to brush off the rock every minute or two." And the player is totally pulling this out of her ass based on the fossil lab exhibit at the Field.

Janet peered at Sharon's fossil. "What do you think you have there?"

Re: Discussion/Assignment!

[sharon-valerii.livejournal.com]

"I think it's a fish." Sharon made a face. Fish were a bit too fishy for her. Absently, she brushed a chip off her cheek before continuing to methodically uncover the fossil.

"I suppose we'll find out at the end of class," she said. "Are you looking forward to the field trip?"

Homework!

Hand it in here.

*hands in assignment, complete with stick figures and precise calculations*

1. 150 pounds.

2. 120x5 = 600 pounds. 600 + 100 + 20 + 150 = 870

3. 4 x 870 = 3480

4. 150 + 200 + 20 + 20 = 390 + 400 = 790 + 3480 = 4270 - total truck capacity: 4200 pounds. The answer is no. The jackhammer stays. Capacity without jackhammer: 3870.

5. *stick figures*

6. 3870 - 2400 = 1470 + 100 = 1570. 4200 - 1570 = 2630 pounds of fossil can return with us.

Re: Homework!

1. 150 pounds

2. (1 day of food for 1 person x 120 days) + baggage + tent + body weight = total weight of 1 person
(5 x 120) + 100 + 20 + 150
600 + 100 + 20 + 150
870 pounds = total weight of 1 person

3. total weight of 1 person x 4
870 pounds x 4
= 3480 pounds

4. Total weight of equipment = excavation tools + 4 filled gas cans + truck emergency kit + medical kit
Total weight of equipment = 150lbs + 200lbs + 20lbs + 20lbs
Total weight of equipment = 390lbs
Total weight = total weight of equipment + total weight of people
Total weight = 390lbs + 3480lbs
Total weight = 3870lbs
The jackhammer is too heavy to bring.

5. Cabin (http://pics.livejournal.com/kawalsky/pic/000069c8) & Roof rack (http://pics.livejournal.com/kawalsky/pic/00007xd9)

6.
Option 1
Returning with all personnel, baggage, tents, tools, kits, gas and 5 days worth of food.
Total Weight = Weight of personnel and gear + tools + kits + gas + food
Total weight = 3480 pounds + 150 pounds + 200 pounds + 20 pounds + 20 pounds + 100 pounds
Total Weight = 3970 pounds
Amount of fossils to bring home = max capacity of truck - total weight
= 4000 - 3970
= 100 pounds

Option 2
Returning with all personnel, baggage, tents, tools, kits and 5 days worth of food but only half of the gas (due to consumption)
Total Weight = 3480 pounds + 150 pounds + 20 pounds + 20 pounds + 100 pounds
Total Weight = 3770 pounds
Amount of fossils to bring home = max capacity of truck - total weight
= 4000 - 3770
= 230 pounds
