Rusty Nails
Over the next week, we will be working on a state required science work sample. The general topics include, What factors make rusting of steel nails worse? or What can be done to steel nails to reduce rusting? Students will write a specific question that can be addressed by a scientific investigation. As their teacher I am not permitted to assist them with any part of writing or setting up the investigation. I will provide materials and a general structure, but it is up to students to plan an experiment that will provide data that will answer their question (including controls). Background information for this experiment should come from, real world observations and lessons 22.2 and 23.2 as well as from the atom packet and lessons on chemical bonds and reactivity. The final draft of the work sample will be produced on a laptop during class and either turned in electronically or printed out and turned in to the turn in basket. Experiments will be set up on Friday,February 8th and they will be left to rust for at least 5 days. Details about how the work sample will be scored can be found in this document provided by the state of Oregon. The due date will be determined at a later date and posted on my assignments page.
