Engineering standards
This shows how the lesson connects to the national NGSS engineering standards and what student work you can collect.
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.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.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
- Gather per-pair materials: Two long paper strips; cardboard base and top; tape; ruler.
- 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.
- Set the size, load or distance marks mentioned in the steps before class. Demonstrate an ordinary first attempt, not a perfect model to copy.
- 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
See the job and plan
- Introduce the finished object: Make a large paper button that rises again after a gentle press using a folded paper spring.
- Draw a button in its raised and pressed positions. Mark where the folded spring will sit.
- Students say what would count as a successful result.
Model the unfamiliar action
- Demonstrate slowly: Tape two strip ends at a right angle. Fold each strip over the other in turn to make an accordion stack.
- Pause so partners can repeat the action; provide prepared parts if cutting or folding blocks progress.
Build the first version
- Tape the spring between a broad base and a light card top. Keep the folds free to open.
- Partners swap builder and checker roles halfway through. Check the working part before decorating.
Try once and save
- Run one trial of the stated test to locate an obvious problem. Do not count a changed procedure as a fair comparison.
- Label and store the model; sketch its current shape and clear the work area.
Predict and set up
- Revisit the two success checks. Agree on identical starting conditions and prepare a before/after results table.
Collect evidence
- Press gently to the teacher-marked height and release five times. Record whether the top rises each time.
- One student operates while the other records. Swap for a later trial while noting a change of operator if it affects the result.
Change one thing
- Change one fold that sticks or reduce the top weight. Repeat the same press depth.
- Keep the original results rather than replacing them with only the best attempt.
Explain and clean up
- Show the button and a side-view sketch with arrows. Turn in five press-and-release results.
- 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.

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
