Sediment Permeability and Porosity Lab

In this lab, students will design and experiment to determine which type of sediment is the most permeable and the most porous. This very open to a student's design. The teacher should give little to no help with this experiment. I use this lab as an assessment of a group's ability to design and experiment and come up with a statement of conclusion. I am looking for their ability to use time wisely, set up an experiment, gather data, practice safe lab techniques, and use variables correctly. Teacher reflection and procedures are included.
