Any information on what you expect our students to be able to do in identifying minerals and rocks.
ANS: Students should be able to determine the physical properties of minerals using a set of simple tools. For rocks, since students are only expected to identify the rock type (without giving the rock name), coaches and students should focus on which rock characteristics can be used to make the distinctions.
For minerals, I’m assuming the students need to do hardness testing and streak testing. What tools should/can they bring (nail, copper, finger nail, etc.)
ANS: The following tools will be provided:
– Copper plate (not included in the mineral kit; a piece of copper pipe or a copper fitting from a home improvement store will work. Do not use a penny, as they are now made of zinc, not copper)
– Iron nail (included in the mineral kit)
– Glass (not included in the mineral kit; pretty much any smooth glass will work)
– Streak plate (included in the mineral kit)
– Students should know how to use their nails to test for hardness
Can they bring other materials that are useful for hardness testing.
ANS: All the tools needed for mineral testing will be provided EXCEPT finger nails. Students should use their own. They will not be allowed to bring anything else.
Do they need to test for specific gravity of a mineral?
How accurately will they need to identify a particular mineral.
ANS: Students will be provided with a table that will be organized in a manner similar to the one included in the mineral kit, plus a column for cleavage. After testing for physical properties, they will use the table to identify each mineral. Points will be awarded for correctly identifying the mineral properties, as well as the mineral name.
I saw the answer to a previous question relating to identifying rocks as igneous, sedimentary, metamorphic along with other specifics in the answer. Is there anything else they need to identify related to rocks?
ANS: yes, they will need to justify their answer, or explain what properties of the rock sample made them decide what type of rock it is.
Is there going to be acid available for identifying calcite and limestone?
ANS: For safety reasons, acid testing will not be allowed. If necessary, the information will be provided.
Is there going to be a black light available for identifying fluorite?
Can you post the “A reference table will be provided during the test” that you refer to on the original even description? “
ANS: no, the table will not be posted. Use the one included in the mineral study kit for practice (which is missing the column for cleavage, but the info can be found online). If you have your own minerals, use the website provided in the event description to create a similar table, and have your students practice with it.
Is there a master list of ROCKS and MINERALS that the students should use as “syllabus” for this event? The total list of rocks and minerals runs in the thousands and I was wondering which rocks and minerals should the students focus on, for their practices. The WESO sample kit only has a handful in it…
ANS: We do not have a master list. Students will be quizzed on their ability to test the physical properties of minerals, so any common mineral will work for practice. See answer above for more details. For rocks, since students are only expected to identify the rock type (without giving the rock name), coaches and students should focus on which rock characteristics can be used to make the distinctions.
