RUST WORK SAMPLE: A work sample is a complete scientific investigation from start to finish. Students think of and write the question, provide background information, make a hypothesis, write a procedure, identify variables, do the experiment, collect data and analyze it and draw conclusions. The final product will be produced entirely on the iPads.
Students will take what they have learned about chemical reactions and reactivity of different metals to ask a question about rusting/corrosion. The big umbrella question is What kinds of conditions make rusting/corrosion worse or better? Students will think of a question and design an experiment using metal pieces or nails in test tubes or petri dishes with different environments. The experiment should compare corrosion of different metals in the same environment or compare corrosion of the same metal in different environments. Another approach is to loo at rust prevention. Students can use uncoated steel nails and coat the nails in order to try to prevent rusting or use pre-coated nails such as galvanized nails (zinc coated, copper coated etc). For analyzing results, students will create a rating scale for rusting/corrosion and use before and after photographs taken with the iPads. A graph of the ratings will be a part of the analysis page.
BACKING UP YOUR WORK: Save to your Edmodo backpack, Files 1 server, or a drop box account if you have it. If your iPad were to get damaged or erased everything within the pages app would get wiped clear, so do back up your work often.
TEMPLATE FOR WORK SAMPLE: Here is the basic template for the work sample in Microsoft Word. When students open it on the iPad they should save it in Pages right away.
IF YOU MISSED INSTRUCTIONS IN CLASS: In class I went over the four main sections of a science work sample. Here is that introductory smart board presentation.
SCORING OF THE WORK SAMPLE: How will student work be scored on this project? Here are downlaodable PDFs of two types of score sheets. The first one shows what must be accomplished to receive a meeting score of a 4 on each section of the work sample. The second score sheet has a description of not meeting, meeting and exceeding for each section of the work sample.
