Description
If you’re looking for a FUN and AUTHENTIC introductory digital lab for your Types of Rocks Unit that imitates the work of REAL GEOLOGISTS, then this is the Claim Evidence Reasoning (CER) activity for you! Students bring in a rock of their own (or supplied by the teacher) and make a claim about how or where their rock formed. They gather evidence on a worksheet with simple tools such as a magnifying glass, balance or whatever other tools you want them to use. Then, they either keep their claim or revise theirs and explain in their reasoning why their evidence matches their claim. An example is provided! Great as an intro to studying the types of rocks and the rock cycle! Here’s a great digital
notebook that can be used to teach the 3 rocks and rock cycle next!
This low prep product is aligned to the following standards:
NGSS Performance Expectation: MS-ESS2-2. Construct an explanation based on evidence for how geoscience processes have changed Earth’s surface at varying time and spatial scales.
Texas TEKS: 6.10B Classify rocks as metamorphic, igneous, or sedimentary by the processes of their formation.
*Example CER* Included
Claim: My rock was formed from bits and pieces of other rocks stuck together.
Evidence:
- Saw little pieces of rock in my rock
- When I scratched it, pieces fell off
- Feels light.
- Measured 10 grams
Reasoning: I think that my rock formed from pieces of other rocks that somehow got glued together. When I observed the rock closely, I could see little pieces of rock so maybe they landed somewhere together and got stuck. The rock felt light to me so I think there are air spaces in between the rock pieces proving it’s made of pieces.
This resource includes:
1. Student Worksheet
2. Example CER
3. Tips for the teacher
