POE Unit 3 • Lesson 3.3

Flowcharts and Algorithms

Write a mission algorithm and convert it into a clear flowchart with decisions and loops.

Lesson Snapshot

Student Objective

I can create a flowchart that shows the logic of an automated aerospace mission.

Main Activity

Write a mission algorithm and convert it into a clear flowchart with decisions and loops.

Deliverable

Mission flowchart draft

Tools / Materials

Notebook, flowchart symbols, whiteboard, website

1ProblemUnderstand the challenge and why it matters.

Programming a rover or VEX system without a plan often leads to unsafe behavior, repeated mistakes, or confusing code. Engineers use flowcharts to plan logic before testing hardware.

2ConceptLearn the engineering idea or skill.

A flowchart represents an algorithm using process blocks, decision diamonds, start/end symbols, and arrows. It helps a team see sequence, conditions, loops, and possible failure paths.

3ApplyUse the skill in a guided task.

Draft a flowchart for a simple rover mission or VEX ground-support task with at least one decision point.

4DocumentRecord your evidence and decisions.

Record the flowchart in your notebook or submit a digital version with clear labels and a brief explanation of the intended behavior.

5ReviewCheck quality and identify your next step.

A strong flowchart can be followed by another student without needing verbal explanation.
