The links below will take you to other sites where you can find additional STEM education resources. Some are free, others are not. All, though, have content, philosophies, or both that we believe are consistent with what the Excalibur Solutions STEM Academy aims to provide.
The Raspberry Pi Foundation is a UK-based registered charity focused on providing STEM resources and other support for educators. Much of the content is focused on the use of the Raspberry Pi and on making (as in maker spaces) more generally. There is an almost overwhelming amount of information, so be prepared to spend some time looking around.
Founded by two Texas A&M Aerospace Engineering graduates, Vivify STEM provides a wide array of teacher resources for STEM education. From pre-packaged lessons to teacher training to a weekly podcast, Vivify STEM is definitely worth a look if you are looking for help incorporating STEM in the classroom. Some of the content is for sale, but there is a non-trivial amount of free content as well, including a newsletter delivered right to your inbox.
When founder Dori Roberts was unable to find STEM opportunities for her own elementary-age children, she created her own. Then, when she started to receive requests for her services outside the region she could effectively maintain, she franchised the program. Today, over 10 years later, Engineering for Kids has over 150 locations in more than 35 countries. The Engineering for Kids program is delivered via after-school clubs, summer camps, in-school field trips, and the like with classes taught by their own trained instructors. Their content is aimed at elementary and middle school.
Instructables is an on-line community of makers. Members post projects that they have made with step-by-step instructions so that others can replicate them. When you sign up (which is free), you get a newsletter with new project ideas delivered right to your inbox. Projects vary from wood working to electronics to knitting to cooking and more. Skill level and complexity vary, too, so there are options for nearly everyone. One of my favorites has been instructions for creating a felt hippopotamus head suitable for mounting.
