Watch the Overview
Each challenge has its own detailed blog post including a regular & pandemic makeover video walk-through linked below:
* Flower Frenzy is comprised of the following four flower mini challenges:
- Floating Flowers
- Fluff & Flatten Flowers
- Functional Flowers
- Firmly Fixed Flowers
Materials for all challenges were procured at the Dollar Tree except a large box of craft sticks (Michael’s) and candy (Target).
I recommend one challenge per day or week leading up to Valentine’s Day, or even all challenges in one day-long 5-event pentathlon! STEM challenges are always most beneficial when done in multiple iterations, however they can be treated as one-off activities as well.A brief description of each challenge is available below, and more information is also available by clicking on each challenge title.
