For this project, students are given scrapbook paper and scrapbook butterflies of two different colors (or whatever organism you want!). One of the colors blends in with the background paper.
Without too much direction (other than the basics--this allows for creativity and seeing what the students know!), students need to create a model of natural selection using the materials (they should definitely know what natural selection is before doing this project). They take pictures, import them into a screencast program, and add their voices over the top to explain the model of natural selection.
I also don't provide much instruction on how to use the technology. As we all know, most kids are quick learners--especially when it comes to technology--so I let them mostly figure it out on their own. I did download Lensoo myself and played with it beforehand, and Iv'e used Screencastomatic before, so I would suggest becoming at least *slightly* familiar with them before proceeding. However, I mostly let the kids do it themselves.
I gave my students three in-class work days for this project. They had one more day outside of school before the project was due on the fifth day. I found that it was a GREAT way to assess their understanding of natural selection (and pull in some modeling!).
The videos end up being about a minute long--the projects are easy to grade (rubric included) and I actually find them enjoyable to watch! They are especially fun when kids pull in unexpected, creative aspects into their videos!!!
