Students can send in anything they'd like, from a broken iPhone, to a dead insect, to chewed gum. The SEM has a scan range of 100nm to 5mm and an imaging resolution of 25nm, capable of bringing the smallest samples into focus. ASPEX will scan submitted samples and then post before/after photos along with an analytical report online. This allows viewers to see what the sample looks like to the naked eye as well as under the SEM.
You can send students to the site right now to visit the SEM Image Gallery where they can see samples of already scanned objects, including mold, cat hair, fly eyes, an old toothbrush and more. What's more students can have the experience of writing authentically because comments are allowed on each before and after photo series. Educators can teach students how to join the conversation with real audiences leaving thoughtful and appropriate comments that add to learning of all. When students images are posted, encourage them to write comments on images of their classmates.
Students can also engage in a fun contest on the site right now is called "Name that Sample!" Each week magnified images are shown and the person who guesses it right or closest, wins a prize. Right now the prize is a brand new Netbook providing a fun and innovative way to encourage learning, communication and team building.
So what are you waiting for. Go to http://www.aspexcorp.com/resources/send_sample.html, check it out, then have your students send in their samples!
