1. Sedimentary Rocks To know how sedimentary rocks are formed Can you unscramble the following sedimentary rocks: Lomeienst Ssotadntn Slsneoitt Slahe Casneolyt

2. What does the term “sedimentary” mean? Can you break the word down? Sediment – What does this mean?

3. Sedimentary Rocks SandSandstone

4. Sandstone Formation Sandstone was originally loose sand on the floor. Since then the grains have become stuck together You are going to investigate how this could have happened… How do you think particle size can affect the strength of the rock?

5. Sedimentary Experiment Smear a small amount of petroleum jelly around the inside of the syringe Make some sand damp in a plastic cub by adding a small amount of water to it: fill your syringe with this damp sand Put your fingers over the end of the syringe and press the plunger in as hard as you can Take your thumb away and gently push the sand pellet out of the syringe onto a piece of paper Repeat this using damp sand and gravel; then repeat again using damp sand and plaster of Paris and any other combination of the 3. Leave your pellets to dry for 10-15 minutes

6. Design an experiment that could be used to test the strength of the sedimentary rocks you have formed. Independent Variable: Dependant variable: Control Variables: Type of data: How does the particle size affect the strength of the rock?
