Lesson 4: Ping Pong Dunk Challenge

1. How does your "depth perception" change when the target is a hole rather than a flat surface?


2. Why is it more efficient to move multiple joints simultaneously rather than one at a time?


3. Where is the optimal "release point" to ensure the ball doesn't bounce back out of the hole?

Trajectory, Payload, Cycle Time, Throughput, Release Point, Overtravel.

NGSS MS-ETS1-2: Evaluate competing design solutions using a systematic process to determine how well they meet the criteria and constraints of the problem.


CSTA 2-CS-03: Systematically identify and fix problems with computing devices and their components.

Description: A speed and accuracy lab where students move 5 balls into a target hole (usually cut into a shoebox or a PVC pipe).


Purpose: To simulate industrial "pick-and-place" robotics where speed and repeatability are the primary goals.


DOK Level: 3 (Strategic Thinking)

In this course, we recognize that students enter the lab with varying levels of technical experience. Our differentiation strategy employs a 'Scaffolded Autonomy' approach. We provide structured, step-by-step guidance for foundational concepts while offering open-ended, 'Design Challenge' extensions for advanced learners. By utilizing peer-mentorship models, diverse instructional media (visual, tactile, and digital), and flexible project pathways, we ensure every student can move from consumer to creator at their own pace.

The 5-Ball Efficiency Test: Students must "dunk" all 5 balls. Assessment is based on the success rate (balls in vs. balls missed) and a short verbal explanation of how they adjusted their "swing" to compensate for the ball's momentum.
