Earth Science Objective: Rocks and the Rock Cycle
• Distinguish between mineral and non-mineral objects
• Identify or choose examples of factors used to classify rocks
• Distinguish between intrusive and extrusive igneous rocks
• Distinguish between clastic, organic, and chemical sedimentary rocks
• Distinguish between foliated and unfoliated metamorphic rocks
• Predict whether the crystals of a particular type of mineral will be large or small depending on how the mineral cooled.
• Select the proper explanation of why or how igneous, sedimentary , and metamorphic rocks formed
• Sequence possible steps in the rock cycle
I set up these labs the following way for my HS level students
Day 1 Introduce minerals, rocks, and the rock cycle
Day 2 Review minerals, introduce using observations to identify minerals, identification lab
Day 3 Igneous rocks – review rock cycle, intro igneous rocks (vocab builder), identification lab
Day 4 Sedimentary rocks – review rock cycle, intro sed rocks (vocab builder), identification lab
Day 5 Metamorphic rocks –review rock cycle, intro met rocks (vocab builder), idenfication lab
• I always put metamorphic rocks last so that we can discuss the idea of “parent rocks”
Many of the answers to the labs are dependent on the samples you choose.
The minerals lab is an exploration of the characteristics of minerals, and minerals are grouped based on chemical classes. Tests are meant to highlight the variation AND similarities within each class of minerals.
The rocks labs are intended to highlight the ways that we identify each kind of rock.
Sedimentary rocks – by grain size and composition
Igneous rocks – by texture and composition
Metamorphic rocks – by foliation and composition
