I absolutely love the work of this teacher! Sue Cahalane has an amazing blog called "Science for Kids" and if you haven't checked it out yet, you should! Click here for the link to this wonderful science blog. She just created a packet based on the Engineering Design Process and it is super easy to understand and use! The primary teachers at my school love it and it would be a huge help to anyone starting out (or anywhere in) the STEM process!
Here is the link to this fantastic freebie! Check out her store, it is full of great science resources specifically designed for K-4 kids!
