What will you make and do?

Make a large paper button that rises again after a gentle press using a folded paper spring.

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 a button in its raised and pressed positions. Mark where the folded spring will sit.

  2. 2Make the first parts

    Tape two strip ends at a right angle. Fold each strip over the other in turn to make an accordion stack.

  3. 3Put it together

    Tape the spring between a broad base and a light card top. Keep the folds free to open.

  4. 4Test it fairly

    Press gently to the teacher-marked height and release five times. Record whether the top rises each time.

  5. 5Improve one part

    Change one fold that sticks or reduce the top weight. Repeat the same press depth.

  6. 6Show and turn in

    Show the button and a side-view sketch with arrows. Turn in five press-and-release results.

How will you know it works?

  • Rises after each gentle press
  • Top stays attached for five cycles
  • 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 Make a large paper button that rises again after a gentle press using a folded paper spring. 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: Rises after each gentle press; Top stays attached for five cycles.

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: Press gently to the teacher-marked height and release five times. Record whether the top rises each time. Change one fold that sticks or reduce the top weight. Repeat the same press depth.

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

Materials

  • Two long paper strips
  • cardboard base and top
  • tape
  • ruler
  • Pencil, planning paper and the printable design brief below

Teacher preparation

  1. Gather per-pair materials: Two long paper strips; cardboard base and top; tape; ruler.
  2. Make one rough sample and rehearse the exact test: Press gently to the teacher-marked height and release five times. Record whether the top rises each time.
  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: Make a large paper button that rises again after a gentle press using a folded paper spring.
  2. Draw a button in its raised and pressed positions. Mark where the folded spring will sit.
  3. Students say what would count as a successful result.
Meeting 1 · 8–18 min

Model the unfamiliar action

  1. Demonstrate slowly: Tape two strip ends at a right angle. Fold each strip over the other in turn to make an accordion stack.
  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. Tape the spring between a broad base and a light card top. Keep the folds free to open.
  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. Press gently to the teacher-marked height and release five times. Record whether the top rises each time.
  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 fold that sticks or reduce the top weight. Repeat the same press depth.
  2. Keep the original results rather than replacing them with only the best attempt.
Meeting 2 · 35–45 min

Explain and clean up

  1. Show the button and a side-view sketch with arrows. Turn in five press-and-release results.
  2. Collect the brief and results; separate reusable materials and clean the test area.

Assessment

  • Rises after each gentle press
  • Top stays attached for five cycles
  • Student demonstrates the actual task: Press gently to the teacher-marked height and release five times. Record whether the top rises each time.
  • 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 paper spring button before decoration.
  • Extension after success: choose one more value for the same tested feature, predict its effect and repeat press gently to the teacher-marked height and release five times.

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.
  • Keep pieces on the tabletop, do not mouth materials and stop if a part tears into a sharp or loose hazard.

No-machine alternative

Use prepared paper parts, larger pieces or an adult-assisted version of the same build. Keep the functional task: Make a large paper button that rises again after a gentle press using a folded paper spring. If physical testing is not possible, label sketches as predictions rather than measured results.

Printable student design brief

The challenge

Make a large paper button that rises again after a gentle press using a folded paper spring.

Success criteria

  • Rises after each gentle press
  • Top stays attached for five cycles
  • 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: Press gently to the teacher-marked height and release five times. Record whether the top rises each time.
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.
