Here are two new pieces for your Properties of MINERALS Unit! A fantastic DataLAB where students ANALYZE 2-4 pages of different Moh's Scales to compile their OWN Personal Moh's Scale Compilation for their Journals! It shows students there are TONS of different versions-- each with different and various "common objects"-- and if you put them all together-- you get a much more complete version of Moh's Scale, with "Corundum Sandpaper" as a test for as high as 9.0 on the scale! It also gives many example Minerals, including a list of METALS, and their ranked Hardness on the scale. So, Students also list the "other" MINERALS, like Gold or Nickel, with the same Hardness as those Indicator MINERALS on the Scale. This DataLAB is student-centered and gives them another Practice with "gathering INFO from Charts/Graphs" which is always a difficult Science Standard.
The second piece is a Daily Mystery MINERAL Hardness PUZZLE that will allow YOU to see who your resident "Sherlock" is! Student TEAMs use Clues to deduce which MINERAL (A through G) is which and its RANKING on Moh's Scale! This is a GREAT way to get STUDENTS very comfortable with Moh's SCALE and "scratched-by" vs. "scratches" with the tools on the Scale. It also includes an "upside-down" Moh's Scale to use for half of the 6 day PUZZLE, so that students aren't TRICKED by a reverse scale(10-1) on an ASSESSMENT --as mine were:) This is one of my student's MOST FAVORITE activities all year, and it fits into your class just after WarmUPs, but before the daily LAB or Activity! Make it a RACE to WIN for TEAMS and collect points for all 6 days on the included TEAM TALLY CHART!
As always, I have thrown in several FREE EXTRAS from my MINERALS Unit and some others for you to check out-- and hopefully you'll see the time and care that I put into my work-- and allow me to PLAN your next Unit! If you need me-- please email me at firstname.lastname@example.org for fastest response. Please let me know if I can help in any other way to help you ROCK the SCIENCE IN YOUR CLASSROOM!
