In this lab student 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 on a groups 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 to use variables correctly. Teacher reflection and procedures are included.
