In the STEM Lab, just like any other classroom, we always have items that we would like to have. I have a project on DonorsChoose.org to get 6 Kindle Fire 8 for our STEM Lab to use with our Sphero SPRK+ robots. On Amazon I have two wish lists for the STEM Lab. One is filled with books and and the other is full of materials that we would like to have. If you would like to get a book for the STEM Lab, I alway check out Abebooks to see if a slightly used copy is available with free shipping. I also have a list of items that people often have around the house that we would be happy to have in our classroom for our projects.
