Rocks and Minerals: Model the Process of how Sedimentary Rocks form

Make your own sedimentary rock in this lab. Mix sand, clay, and pebbles along with water and common salts to create a sedimentary rock. This is a nice activity to add to studies of crystal structure or the rock cycle. The fragility and granular nature of sedimentary rocks are clearly seen. Simple directions allow kids to do this on their own or with limited supervision. 


What's Included:

✅ Task Card instructions
✅ Student Sheet for capturing observations
✅ Answer Key to Student Sheet
✅ Student Reading with Questions
✅ Answer key to Student Reading questions.
✅ Teacher Notes with prep, set up, and explanations.

☀ How do sedimentary rocks form?
☀ What holds sedimentary rocks together?
☀ Why can you see grains in sedimentary rocks?


Topics & Concepts Addressed:

✦ Sedimentary rocks are made of sediment that's compacted.
✦ Sedimentary rocks are made of sediment that's cemented with minerals
✦ Sedimentary rocks form when water evaporates leaving minerals behind
