Discuss rock properties and how students can identify an unknown rock (lustre, scratch test, sound volume/pitch). Students investigate their rock by using a scratch test, and tapping their rock to observe the sound made. Wrap up: Discuss student answers/ observations.
*This activity will require rock samples.
-
Discuss the different types of rock (igneous, metamorphic, sedimentary) and the clues students can use to identify an unknown rock (texture, size, lustre, scratch test, etc.). Students are given a rock to observe and answer questions on the activity sheet. After answering the questions 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 vinegar and rock samples.
-
Students find a large rock in the natural area to observe and write a short story about. This story could be fictional or based solely on observation depending on teacher preference. Wrap up: Review stories and how ideas came from observation.

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.
-
Discuss states of matter, chemical reactions, materials, products and examples. Students search for examples of each state of matter and chemical reactions in the natural area. Wrap-up: what reactions are happening and why are they important?
