Recently I stumbled upon a series of videos called "5 Levels of Difficulty". In each video an expert explains a difficult concept in 5 levels of increasing complexity:
I was inspired by this video series for a few reasons. First, it reminded me how explaining a difficult concept to a novice and expert audience simultaneously requires deep conceptual knowledge and how listening to such an explanation helps to build simultaneous conceptual and mechanical knowledge of a concept. Second, it motivated me to reimagine how I assess my students.
Keeping the above in mind, for our unit on Cellular Respiration in my freshman Biology course, rather than assign a traditional topic exam, I decide to create a variation of the 5 Levels of of Difficulty videos shown above that will serve as the assessment for this topic. In short, students will create similar videos explaining Cellular Respiration at 3 rather than 5 levels of difficulty.
I have embedded a document below that explains the intricacies of the assignment. Click here to view the spreadsheet where student "3 Levels of Difficulty" scripts and videos will be collected.
Campers spent day 1 using the Microbit to learn the basics of interfacing physical hardware with coding. Campers worked through a series of modules, leading to their own invention that they will showcase on our final day. Click here to see all modules via our leaderboard, and click here to see the handbook that contains links to all activities. A few images from today are shown below.
During Day 1 of the STEM portion of "Soccer & STEM Camp", campers built ball pitching machine to experiment with the process of "gearing up". After building the same machine, campers were challenged to modify their projects to change the speed and/or structure of their machine. Today, Day 2, campers will apply their knowledge of gearing to build a Robotic Dragster. See a few images of Day 1 below.

During our first day of Invention Camp, campers built simple "walkers" from instructions, then leveraged their knew knowledge to invent their own Walker. Below are two examples of the many incredible Walker inventions. I will post a more complete video of all Walkers tomorrow.
