In honor of Citizen Science month, here are some science-related projects available on the site. If you haven’t registered yet, done a project, or posted one, here’s how to get started. Also, don’t forget that Evernote now offers a Make: Projects Notebook in their “Trunk” area, so you can add (select) Make: Projects to your notebooks.
