Lab Manual: There is actually no separate lab manual to buy this semester. You will be provided with background readings and videos on ELMS, as well as a packet of questions to answer. The answers for the lab are due online on ELMS; some will be entered as online quiz questions; others will require you to scan and upload charts, maps, etc.
Hand Lens: For the lab, it would be helpful to have a 10x or more powerful handlens for observing specimens (higher magnifications are also useable). There is a very reasonably priced set of 10x, 20x & 30x handlenses without built in lights you can get on Amazon.com https://www.amazon.com/Jewelers-Jewelry-Magnifying-Magnifier-Supplies/dp/B094FPKJQ6/">here, or a 30x and 60x with a built in light at here, but you can find them at other sources, too.
(Recommended) Drawing Tools: A colored pencil set and a ruler/straight edge will be helpful in some of the labs.
Recommended: Access to a scanner to make uploadable versions of your maps and charts. Many modern home printers have a built-in scanner function, so some of you may have a scanner you weren't aware of!
LAB POLICIES
The point of the lab is to hone your skills as an observer and to teach you the methods of the field. It is vital that you actually examine the specimens yourselves so that you can discern the various features and attributes of the rocks and fossils.
Please read the introductory material on ELMS by the time we meet in lab.
Labs are due the next lab meeting (1 week later). If they are turned in by the next class time (Friday) there will be a 10% grade reduction; on the following Monday a total of 30% grade reduction; and a full week late will garner a 50% grade penalty. Labs won't be accepted for a grade later than 1 week overdue (barring legitimate extenuating circumstances.)
You are encouraged to collaborate and interact with each other and with Dr. Holtz while working on the labs. However, all work you turn in must be your own.
If you are having problems, don't be shy; ask for help!
Lab specimens will remain out for your examination through the end of the week and on the following Monday. However, Dr. Holtz will typically replace lab specimens sometime on Monday afternoon.
DON'T be a specimen hog! Make sure that others get adequate access to the hand
samples.
ALWAYS return specimens to their appropriate boxes
Use the dilute HCl wisely:
Use small drops, only leave it on long enough to validate whether there is effervescence or not; and wipe it up afterwards.
Leaving acid on the hand samples will allow the reaction to run its course, and leave a reaction rind on the rock. This will mislead students in the future)
In general, only use acid on fresh surfaces.
Unless directed, don't drop acid on the fossils.
We have limited samples, so please be careful with them. Doubly so with the fossils!!
