What will you make and do?

Build an upright paper wheel that spins freely on a straw axle for at least five turns.

Teacher overview: Students will plan the specific object described below, make and test a first version, then use their results to improve it. Read one step together, demonstrate the unfamiliar action, and let students complete that step before moving on.

  1. 1Plan your project

    Draw the wheel, axle and two supports from the front and side. Mark the center.

  2. 2Make the first parts

    Join the plates for stiffness, make the adult-prepared center hole and place the wheel on its axle.

  3. 3Put it together

    Build two equal stand supports so the axle is level and the wheel does not rub the base.

  4. 4Test it fairly

    Give the same gentle push three times and count full turns before stopping.

  5. 5Improve one part

    Change one axle alignment, support gap or rubbing edge and repeat.

  6. 6Show and turn in

    Submit the finished spinning paper wheel, two labeled ideas and before-and-after evidence. Explain which change the results support.

How will you know it works?

  • Wheel makes at least five full turns
  • Stand remains upright while the wheel spins
  • Record the stated test and explain one revision

Before you move on

Tell a partner what you are making. Point to the part you will work on next. Draw or dictate your test notes if writing slows you down.

Machine cutting, printer setup and electrical power-on require adult approval. A basic-materials model is a valid way to demonstrate the design when equipment is unavailable.

Keep your plan, test notes and before-and-after evidence with the printable design brief below. Use the detailed teacher plan and any coding guide for tool instructions. These steps continue across the lesson’s meetings, not all in one sitting.

For teachers

Engineering standards

This shows how the lesson connects to the national NGSS engineering standards and what student work you can collect.

Assessed

3-5-ETS1-1

Define the need in Build an upright paper wheel that spins freely on a straw axle for at least five turns. Agree on the two success checks and the listed material limits.

What students show: Two labeled ideas with the target and limits stated.
Practiced

3-5-ETS1-2

Compare the ideas using the project checks: Wheel makes at least five full turns; Stand remains upright while the wheel spins.

What students show: A selected design with a reason connected to a success check.
Assessed

3-5-ETS1-3

Test, change one feature and retest: Give the same gentle push three times and count full turns before stopping. Change one axle alignment, support gap or rubbing edge and repeat.

What students show: Before-and-after results collected under the same conditions.

Materials

  • Two paper plates
  • paper straw
  • wooden dowel prepared by teacher
  • cardboard stand
  • tape
  • marker
  • Pencil, planning paper and the printable design brief below

Teacher preparation

  1. Gather per-pair materials: Two paper plates; paper straw; wooden dowel prepared by teacher; cardboard stand; tape; marker.
  2. Make one rough sample and rehearse the exact test: Give the same gentle push three times and count full turns before stopping.
  3. Set the size, load or distance marks mentioned in the steps before class. Demonstrate an ordinary first attempt, not a perfect model to copy.
  4. Prepare any holes, fasteners or difficult cuts for students. Check the stated safety note and clear the testing space.

Step by step

How to teach it

Meeting 1 · 0–8 min

See the job and plan

  1. Introduce the finished object: Build an upright paper wheel that spins freely on a straw axle for at least five turns.
  2. Draw the wheel, axle and two supports from the front and side. Mark the center.
  3. Students say what would count as a successful result.
Meeting 1 · 8–18 min

Model the unfamiliar action

  1. Demonstrate slowly: Join the plates for stiffness, make the adult-prepared center hole and place the wheel on its axle.
  2. Pause so partners can repeat the action; provide prepared parts if cutting or folding blocks progress.
Meeting 1 · 18–35 min

Build the first version

  1. Build two equal stand supports so the axle is level and the wheel does not rub the base.
  2. Partners swap builder and checker roles halfway through. Check the working part before decorating.
Meeting 1 · 35–45 min

Try once and save

  1. Run one trial of the stated test to locate an obvious problem. Do not count a changed procedure as a fair comparison.
  2. Label and store the model; sketch its current shape and clear the work area.
Meeting 2 · 0–8 min

Predict and set up

  1. Revisit the two success checks. Agree on identical starting conditions and prepare a before/after results table.
Meeting 2 · 8–23 min

Collect evidence

  1. Give the same gentle push three times and count full turns before stopping.
  2. One student operates while the other records. Swap for a later trial while noting a change of operator if it affects the result.
Meeting 2 · 23–35 min

Change one thing

  1. Change one axle alignment, support gap or rubbing edge and repeat.
  2. Keep the original results rather than replacing them with only the best attempt.
Meeting 2 · 35–45 min

Explain and clean up

  1. Submit the finished spinning paper wheel, two labeled ideas and before-and-after evidence. Explain which change the results support.
  2. Collect the brief and results; separate reusable materials and clean the test area.

Assessment

  • Wheel makes at least five full turns
  • Stand remains upright while the wheel spins
  • Student demonstrates the actual task: Give the same gentle push three times and count full turns before stopping.
  • Record includes failures as well as successes.
  • Student identifies one changed feature and uses the retest to explain the result.

Supports & extensions

  • Provide fold marks or pre-cut parts; accept drawings or dictated observations.
  • Start with the smallest working version of spinning paper wheel before decoration.
  • Extension after success: choose one more value for the same tested feature, predict its effect and repeat give the same gentle push three times and count full turns before stopping.

Safety & responsible use

  • Teacher checks materials and test conditions before use. Use classroom scissors; adults prepare difficult cuts, holes and fasteners.
  • No powered tools, coding, hot glue or electrical circuits are required. Keep moving objects contained and test loads light.
  • Adult prepares holes and trims axle ends. Spin gently and keep faces away from the axle.

No-machine alternative

Use prepared paper parts, larger pieces or an adult-assisted version of the same build. Keep the functional task: Build an upright paper wheel that spins freely on a straw axle for at least five turns. If physical testing is not possible, label sketches as predictions rather than measured results.

Printable student design brief

The challenge

Build an upright paper wheel that spins freely on a straw axle for at least five turns.

Success criteria

  • Wheel makes at least five full turns
  • Stand remains upright while the wheel spins
  • Record the stated test and explain one revision

Constraints

  • Use only the listed teacher-approved materials
  • Stay within the teacher-set size, load and test-space limits
  • Two 45-minute meetings; keep the first version simple

Engineer’s notes

Who uses this object, and what should it do?
Draw two possible designs. Label the working parts and circle your choice.
Which size, fold, gap or position must you measure or mark?
Before testing, predict what will happen: Give the same gentle push three times and count full turns before stopping.
Record each trial: condition / expected result / actual result.
Draw the ONE change you made. What stayed the same?
Record the retest. Did the change help, not help, or leave the result uncertain?
Show and explain: one result that supports your conclusion.
