Time: 45 to 55 minutes (build, troubleshoot, and draw)
Big idea: Electricity flows in a closed circuit and can be transformed into motion. Students build a circuit that powers a motor, turn the motion into art, and debug their bot like real engineers when it will not run.
Standards Snapshot: Virginia SOL + NGSS
Anchored at grades 4 and 5, where circuits and energy transformation live in both frameworks.
| Grade | Virginia SOL | NGSS | Students walk away able to… |
|---|---|---|---|
| 4 | — | 4-PS3-2 · 4-PS3-4 (primary NGSS fit) | Show that energy moves from the battery through the wires to the motor, in a device they designed, tested, and refined. |
| 5 | 5.4: electricity flows in circuits (open and closed), through conductors, not insulators, and is transformed for use in daily life (primary fit) | — | Build a working closed circuit, diagnose an open one, and trace the energy from chemical to electrical to motion. |
| 5 | 5.2: energy and forces affect the motion of objects | — | Explain that the spinning off-center cork makes the whole bot vibrate, and vibration plus marker legs makes the art. |
| Looking ahead | Middle school physical science | MS-PS3-5 | Arguing from evidence about energy transfer starts with tracing it through this bot. |
| K–5 | X.1: Scientific and Engineering Practices | 3-5-ETS1-2, ETS1-3 | Predict, test, troubleshoot a failed design, and improve it based on evidence. |
Practices exercised (both frameworks): planning and carrying out investigations · analyzing what went wrong (troubleshooting IS data analysis) · designing, testing, and refining a device · constructing explanations from evidence. NGSS Crosscutting Concept: Energy and Matter · Systems and System Models.
Curiosity & Wonder
Do not define circuits yet. Hold up a battery.
“There is energy trapped inside this little can right now. It has been in there, waiting, since the factory. Today we are going to let it out, send it down a wire, turn it into motion, and turn that motion into art. But the energy will only come out if we build it a perfect unbroken path. One loose wire, and nothing happens. Ready?”
That “one loose wire” line is a promise: several bots will not work on the first try, and the class now knows the reason will be findable.
The Build
Materials per student: cup, motor, cork, battery pack with batteries, double-sided tape, popsicle sticks, markers.
- Press the cork onto the motor shaft.
- Slide open the battery holder and insert the batteries, matching the + and − symbols on the batteries to the symbols printed inside the pack.
- With the pack switched OFF, connect the RED motor wire to the RED battery pack wire, and BLACK to BLACK.
- Tape the flat side of the motor to the bottom edge of the cup. Keep the shaft clear so the cork can spin freely without hitting the cup. Add popsicle sticks to adjust the motion.
- Tape the battery pack to the opposite side of the cup, switch facing out and down.
- Tape markers inside the cup as legs so the bot stands on its own marker tips. Let your creativity fly!
- Caps off, switch on, place on paper, and watch it draw.
Productive struggle moments
Our STEM projects are designed so that participants get it wrong before they get it right. You will observe your students struggling as they attempt to create their own STEM projects. This process is an empowering experience, building perseverance, frustration tolerance and growing overall confidence! With your support, students will step out of their comfort zones to think, build and problem-solve for themselves.
- Battery direction. Backwards batteries mean a dead bot. Ask: “Check the symbols. What do you notice?”
- Loose connections. If anything is loose, the bot stops. This is not an annoyance; it is the lesson (see the Investigation).
- Red to red, black to black. Crossed wires are the classic error. Have students trace each wire with a finger before switching on.
- Balance. A constantly vibrating machine shakes itself apart and tips over. Adjusting leg placement until the bot stays upright is engineering iteration, one tweak at a time.
When frustration shows up, narrate instead of fixing: “You are doing the hard part right now. Trace your circuit with your finger. Where could the path be broken?”
The Investigation
Part 1: The dead bot is the curriculum. When a bot will not run, the circuit is open somewhere, and finding the break IS standard 5.4. Teach the debug ritual instead of the fix: check the switch, check battery direction, check red-to-red and black-to-black, wiggle each connection. When the bot springs to life, name what happened: “You just closed an open circuit.” Students who never have a dead bot should help debug a neighbor’s, because the troubleshooting is where the learning is.
Part 2: Trace the energy (grades 4 and 5). Ask students to point along their bot and narrate the journey: chemical energy stored in the battery becomes electrical energy in the wires becomes motion in the motor. The off-center cork turns smooth spinning into wobbling vibration, and the vibration plus marker legs becomes art on the page. Four transformations, all visible, all pointable.
Part 3: Change the art with one variable. Predict first, then test:
- Leg angle: markers straight down versus splayed out. Which draws tighter circles?
- Leg count: three markers versus four. What changes?
- Weight position: move the battery pack higher or lower on the cup. Does the wobble change?
Compare the drawings side by side. The art is the data, and no two bots produce the same evidence.
Skills in Practice
- “My bot would not run because the circuit was ___.”
- “I predict changing ___ will make the art ___.”
- “The energy travels from the ___ to the ___ to the ___.”
- “Next time I would change ___ because ___.”
Real-World Connection
Every device with a battery is running this same show: a closed circuit and an energy transformation. A phone turns electricity into light and sound; an electric toothbrush turns it into vibration (a toothbrush is basically a tidy Art Bot); an electric car turns it into motion. Ask: “What did you switch on today, and what did its electricity turn into?” For grade 5, add the debug connection: when the internet router at home gets restarted or a cable gets rewiggled, an adult is doing exactly what students did today, checking a circuit.
Evidence of Learning
- Grade 4: Student points along their bot and names where the energy starts and what it becomes, in one sentence.
- Grade 5: Student explains one dead-bot fix using the words open circuit or closed circuit, and writes 2 to 3 sentences tracing the energy transformation, backed by their bot’s drawing.
Vocabulary
- circuit: the loop electricity flows through, with a power source, wires, and something that uses the electricity.
- closed circuit: a complete, unbroken loop; electricity flows and the device works.
- open circuit: a loop with a break in it; electricity stops.
- conductor: a material electricity flows through easily, like metal wire.
- insulator: a material that blocks electricity, like the plastic coating on the wires.
- energy transformation (grades 4 and 5): energy changing form, like chemical to electrical to motion.
