Core Skills Analysis
Mathematics
The student worked through AoPS Pre‑Algebra and Intro to Algebra lessons, using Desmos to graph linear and quadratic functions. They solved equations, practiced factoring, and visualised how changes in coefficients shifted graphs. By manipulating sliders in Desmos, they deepened their understanding of slope, intercepts, and the relationship between algebraic expressions and their graphical representations.
Computer Science
Using the Lego Education Spike Prime set, the student programmed robots with the block‑based coding environment, translating mathematical concepts into step‑by‑step instructions. They debugged loops and conditionals to make the robot follow precise paths, reinforcing algorithmic thinking and problem‑solving strategies learned in the AoPS courses.
Engineering & Design
The student explored the Wobbledogs website, building virtual dogs that balance on uneven terrain and then recreated similar mechanisms with Spike Prime bricks. They experimented with joint placement, weight distribution, and pivot points, observing how small design tweaks improved stability, which illustrated core engineering principles of iteration and optimization.
Science (Physics)
Through the wobbledog simulations and the physical Spike Prime robots, the student investigated forces, motion, and friction. They measured how different wheel sizes and surface textures affected speed and acceleration, and connected these observations to the equations of motion they had previously graphed in Desmos.
Tips
1. Extend the algebra work by having the student model real‑world data (e.g., a bike‑riding speed profile) in Desmos and compare predicted versus actual values. 2. Challenge them to design a new wobbledog with a specific function—such as carrying a small payload—and document the engineering design process from sketch to prototype. 3. Introduce a micro‑controller coding project where the Spike Prime robot follows a line drawn on a large sheet of graph paper, integrating coordinate geometry with sensor feedback. 4. Host a mini‑science fair where the student presents how changes in mass and friction impacted the robot’s motion, reinforcing scientific communication skills.
