There is a great opportunity coming up to engage your middle schools students with real data and space imagery. The ISS EarthKAM mission for November is up and running. This mission allows students to request photographs from the ISS. Students enter codewords and lat/long along with orbits for their desired photo location. The digital cameras on the ISS will take the photo and students can analyse the result.
My students in the past have responded well to the nature of the task and it’s real with great teaching opportunties in mathematics and geography. I written more at this previous post. Jump on board at https://earthkam.ucsd.edu
