- Tips for using TI graphing calculators
No naked numbers, a PDF file (red circle with slash) with "naked numbers"
slashed out. A poster to remind students to use units with their numbers. (Two pages, slightly different layout.)
Thanks to Jeff from the NSTA chemistry email list for the idea.
Periodic table spreadsheet (written in QuattroPro, also available in Excel 5/7). Right click to save the spreadsheet to your disk (click and hold on a Mac).
- This spreadsheet has the periodic table on the second sheet, with
each mass named with the symbol of the elements. Thus, typing in =h*2+o will
give you the mass of water.
- The sheet also contains several constants, including gas, Planck's, mass of e-, p+, no, and charge of e-.
first sheet is named "Work Area." Use this sheet to do your work. The second
sheet, "Periodic Table," contains all the values for the molar masses. This
sheet is locked so you can't accidentally type over a value. There is no
password on the lock, so if you need to add another constant, you can simply
unlock the sheet, add your constant, then re-lock it.
WhiteboardsUSA.com is a great source of
pre-cut and finished white boards for classroom use. They are available in multiple dimensions,
and are great groups creating presentations for the class. The site also has a pleathora of tips
on wise use of whiteboards in the classroom. If you have the skills to cut your own Melamine
from your local hardware store, it will be cheaper, but once you factor in your time, these boards
are a deal!
Used lab equipment
Here's a few auction houses that specialize in scientific lab equipment. You probably won't
find class sets of large equipment, but maybe of small equipment, or a few of specialized equipment.
A tip on finding others: Search for the item you want in Google&tm; or another search engine, and
other auction/used sellers may show up.
And there's always eBay.
Where ever you buy used, remember: Let the buyer beware. I would especially say this about eBay,
since the others are targeted toward lab equipment buyers, and as such may be a bit more discriminating.
I've bought quite a bit on eBay, just avoid the deals that look to good to be true (they probably are).
