Mission: Survival Base
3rd Grade Measurement & Time Math PBL | Engineering Challenge for Gifted Learners

What would it take to design a survival base in an extreme environment?

In this high-engagement project-based learning unit, students become engineering teams responsible for designing a fully operational survival base. To succeed, they must apply measurement, problem solving, and time management while working within realistic mission constraints.

Students design a base layout, plan life-support systems, calculate resources, and create a daily operations schedule—all while defending their decisions with mathematical evidence.

This project pushes students beyond procedural math and into real-world problem solving, systems thinking, and decision making.

Perfect for gifted learners, enrichment blocks, STEM integration, or end-of-unit application.

What Students Will Do

Throughout the project, students work through three engineering challenges.

Exhibit 1: Habitat Engineering
Students design a survival base blueprint while working within spatial constraints.

They must:
• Measure and analyze module dimensions
• Design a base layout that fits engineering rules
• Calculate perimeter and material needs
• Evaluate tradeoffs between space and safety

Exhibit 2: Life Support Systems
Students determine how the base will support human survival.

They will:
• Analyze water supply needs
• Interpret measurement diagrams
• Plan cargo supplies within weight limits
• Make decisions about which resources to bring
• Evaluate system failures and tradeoffs

Exhibit 3: Operations Scheduling
Students design a daily operations plan for the base.

They must:
• Read and interpret clocks
• Create a full daily schedule
• Calculate elapsed time
• Adjust plans when mission conditions change
• Evaluate how time impacts safety and productivity

Final Engineering Proposal

Students synthesize their work into a Survival Base Proposal where they must defend their design choices using mathematical reasoning and evidence from their planning work.

Teams present:
• Base blueprint and layout reasoning
• Life-support resource calculations
