Description
In the Ocean Rover Wheel & Axle Lab, students become deep-sea mobility engineers as they investigate how wheel size, axle placement, and surface friction affect a rolling rover's performance on the ocean floor. Set inside the Ocean Explorers narrative theme, this 2-week unit immerses Grade 2 students in hands-on wheel-and-axle science — building, testing multiple configurations, collecting data, and using evidence to identify the most effective design before committing to a final build.
What Students Will Do
* Investigate how wheel diameter, axle fit, and surface type affect rolling distance and stability
* Test at least two distinct wheel configurations on a standardized surface course
* Record zone-by-zone performance data for each configuration
* Use data to identify which configuration performed best and explain why
* Redesign based on evidence and run a final comparison test
What's Included (9 Documents)
* Lesson Plan — Complete teacher guide with full TEKS alignment, day-by-day pacing, learning targets, and vertical alignment notes connecting to prior and future grades
* Training Sheet — Student-facing challenge introduction that connects the narrative theme to the engineering concept, with key vocabulary and a practice activity before any building begins
* Planning Sheet — Structured design document where students sketch, label materials, check constraints, and earn teacher initials before touching any materials
* Data Sheet — Quantitative and observational data collection formatted for this challenge's specific testing metric
* Engineering Rubric — 20-point, 4-category teacher assessment that rewards the engineering process — planning, execution, data rigor, redesign reasoning, and reflection depth
* Redesign Sheet — Evidence-based iteration document requiring students to cite specific data before proposing any build change
* Reflection Sheet — Four structured questions moving students from restating the challenge to analyzing data to proposing a third design to connecting their work to real engineering
* Student Quick Reference — Concise summary card with the challenge, locked constraints, week sequence, team roles, data checklist, and key vocabulary
* Teacher Clarity Guide — Non-negotiables, standardized testing protocol, specific teaching moves, and a Common Mistakes section with exact response language
The Engineering Phase System
Every project moves students through a structured, color-coded arc:
Blue Phase — Plan & Prototype: Students complete vocabulary and concept work, sketch their design, check constraints, and earn teacher approval before any materials are touched.
Green Phase — Build, Test & Improve: Students build, conduct controlled tests, record data, and use evidence to complete the Redesign Sheet before modifying their build.
Purple Phase — Final Test, Reflect & Present: Students run their final locked test, complete the Reflection Sheet individually, and participate in a debrief, gallery walk, or showcase.
Why Teachers Love This
- Complete Engineering Design Process every time, no shortcuts
- Narrative-driven context sustains student motivation through data collection and testing
- Low prep — pick it up and teach it
- 9 fully developed documents, nothing to build from scratch
- Rewards engineering thinking, not just whether the build succeeded
- Vertically aligned — skills build deliberately across grades 2-5
Perfect For
* STEAM Labs
* Science Classrooms
* Engineering & Makerspace Units
* After-School STEM Programs
* Enrichment Activities
* Project-Based Learning Units
* Substitute Plans
Standards Alignment
Aligned to Texas TEKS: Science 2.6(A) force and motion; 2.6(B) patterns in data; 2.2 scientific investigation; Technology Applications 2.1. Crosswalks to NGSS: K-2-ETS1-1, K-2-ETS1-2, K-2-ETS1-3 (Engineering Design).
Part of the STEM with Mr. B K-8 STEAM Engineering Curriculum
This listing is one piece of a complete, vertically aligned K-8 engineering curriculum organized by grade, quarter, and narrative theme. Every project builds on skills from the week before. Quarter bundles, grade-level bundles, and the full curriculum are available in the store.
