Switches + User Control
Circuits + Coding · Simple electronics + Arduino options
Today’s challenge
Invent and compare handmade switches for a useful interaction.
Grade 3 focusPaper circuits, LEDs, handmade switches, block-code demonstrations, and one input/output relationship.
Grade 5 focusBreadboards, resistors, sensors, Arduino or simulator code, debugging logs, and multiple operating states.

Success example · inspiration, not a design to copy
Look closely. What makes this successful?
The switch is easy for the intended user to find and activate reliably.
What to do
- Understand. Read the challenge. Circle the important need, rule, or safety limit.
- Plan. Use the thinking spaces below before you begin making.
- Make. Build, model, code, practice, or investigate carefully with your team.
- Check. Use evidence—not guesses—to decide what worked.
- Improve or explain. Make one useful change or share your strongest conclusion.
Engineer’s thinking
1. Draw and label your plan before building.
2. List the materials, parts, or digital tools you will use.
3. Record one change you make while building.
Evidence check
Show what you learned.
Your teacher will look for: Two switch samples, comparison notes, and a justified selection.
