Activity 01
Stations Rotation: Material Challenges
Prepare four stations with materials: bend paper strips, stretch rubber bands, twist pipe cleaners, compress springs. Small groups spend 7 minutes at each, predicting changes, testing, and sketching results before rotating. Conclude with a class share-out of surprises.
Assess whether all materials possess the ability to be bent or stretched.
Facilitation TipDuring Station Rotation, set one material per table so students focus only on testing and recording, not on moving between items too quickly.
What to look forProvide students with a rubber band and a paper clip. Ask them to demonstrate bending both materials. Then, ask: 'Which material returned to its original shape? Which one kept its new shape?' Record their answers.

Activity 02
Pairs Prediction: Rubber Band vs Stick
Pairs get a rubber band and wooden stick. They predict and test bending and stretching effects, note if shapes return, then swap findings with another pair. Discuss why differences occur using terms like elastic and rigid.
Compare the flexibility of a rubber band to a wooden stick.
Facilitation TipIn Pairs Prediction, insist that pairs write down their reasons before handling materials to make their misconceptions visible before evidence changes their minds.
What to look forPresent students with images of a slinky toy, a metal spoon, and a piece of cloth. Ask: 'Which of these can be easily stretched? Which can be easily bent? Which will likely keep its new shape if bent hard enough? Why do you think so?'

Activity 03
Whole Class Demo: Spring Action
Display a large spring. Students predict stretch and release behavior, then observe teacher demo. Follow with individual quick sketches of changes and a vote on elastic or not.
Predict what happens to a spring when you stretch it and let go.
Facilitation TipFor Whole Class Demo, use a large spring so every student can see the stretch and recoil clearly from their seats.
What to look forGive each student a card with the word 'spring'. Ask them to draw a picture showing what happens when you stretch it and then let go. Have them write one sentence explaining their drawing.

Activity 04
Individual Hunt: Classroom Testers
Students select three classroom items, predict bend or stretch ability, test gently, and record in a simple chart. Share one finding with the class.
Assess whether all materials possess the ability to be bent or stretched.
Facilitation TipDuring Individual Hunt, provide clipboards so students can sketch or jot notes without dropping materials.
What to look forProvide students with a rubber band and a paper clip. Ask them to demonstrate bending both materials. Then, ask: 'Which material returned to its original shape? Which one kept its new shape?' Record their answers.

Generate Complete Lesson→A few notes on teaching this unit
This topic benefits from a cycle of prediction, testing, and explanation, where students’ initial ideas are openly shared, then confronted by evidence. Avoid correcting too soon; instead, use small-group talk and whole-class charting to let students revise their own ideas. Research shows that children learn material properties best when they experience contrasts, so pair stretchy rubber with rigid wood, and temporary changes with permanent ones, to highlight differences.
By the end of these activities, students will confidently name materials as elastic or inelastic based on direct testing, explain how bending or stretching can be temporary or permanent, and compare the behavior of rubber, wood, paper, and metal through clear, evidence-based talk.
Watch Out for These Misconceptions
During Station Rotation, watch for students claiming that all materials return to their original shape after bending or stretching.
Use the Station Rotation tasks to contrast elastic rubber with inelastic items like paper clips and wooden sticks, and guide students to chart ‘returned’ versus ‘stayed changed’ for each material.
During Station Rotation, listen for students saying that bending always leads to breaking.
Set up safe trials with flexible materials like paper or thin wooden sticks, then have students record where bending stops being reversible and ask them to compare results across the station.
During Pairs Prediction, note when students associate stretching only with soft or flexible items.
Ask pairs to predict and then test a metal spring alongside a rubber band, and have them share why the spring stretches even though it feels hard.
