Rock Investigation - Student Stations

Discuss the different types of rock (igneous, metamorphic, sedimentary) and the clues students can use to identify an unknown rock (colour, size, scratch test, vinegar test etc.). Set up 3 stations. Station 1 – Observe and draw the rock. Station 2 -Perform a scratch test. Station 3 – Perform a vinegar test. After recording the results students guess which type of rock they have. Wrap up: Confirm which rock each student has, and walk them through the investigation if necessary.

*This activity will require chalk, paperclips, vinegar, and rock samples.
