TOPIC: Build a Better Rock: Exploring Rock Types
AUTHOR: Nancy Eagle
SCHOOL: Perry Hill Elementary School
DISTRICT: Northwest Allen County Schools
- Know that rocks can be divided into three categories: igneous, sedimentary, and metamorphic.
- Know that rocks are classified by the way they are formed.
- Be able to discern between sedimentary, igneous, and metamorphic rocks by experimenting with temperature & ingredients to create an example of each rock.
MATERIALS & RESOURCES:
- How does heat change things?
- Does the length of time make any difference?
- What do you think will happen to this sediment (brownie mix premixed) when heat is applied for a designated time?
- Will the amount of time it is heated make any difference as to what the sediment turns into?
- Place students into cooperative learning groups.
- Have groups examine the questions above, develop their hypotheses, and determine the scientific method they will use to test the hypotheses.
- Students will then complete their tests using premixed sediment, analyze the results, and record their results.
- Provide each group with a rock sample from each of the three categories, and provide students access to The ACCESS INDIANA Guide to Rock & Soils.
- Using their lab experience and the AITLC Guide, students will identify the classification category of their rock samples. Each group should record their conclusions.
- Closure: Discuss each group's investigation, analysis and conclusions.
- Student ability to match the material made in the lab with the three rock types.
