Use a small design cycle
Tell children they will plan, build, test and improve. Ask them to draw their first idea and predict what will happen. Use clean paper, lightweight cardboard and safe classroom materials. Give every group the same basic rules so they can compare designs fairly.
Challenge 1: A paper bridge
Place two stable supports a short distance apart. Give each group one sheet of paper to span the gap. Children can fold the paper but should follow the same rule about tape. Test with a few lightweight counters, adding them gently in the centre. Stop if the supports move or the bridge becomes unstable.
Challenge 2: A cardboard ramp
Use a small cardboard ramp and a large toy car or other suitable rolling object. Keep the start point and object the same while changing the ramp height. Mark how far the object travels on a clear floor. Ask children what they changed and what they kept the same. Avoid aiming objects toward people.
Challenge 3: A paper tower
Give each group the same number of sheets and a fixed amount of tape. Ask them to build a tower that stands without someone holding it. Test on the same flat surface. Learners can compare broad and narrow bases, then change one part of their design.
Record evidence
Use a simple table with first design, result and change made. Younger children can draw the two versions. Older learners can measure height or distance using the same unit and method. Do not call one design the best until the group agrees on what success means.
Finish with explanation
Ask: What worked? What failed? What would you change next? Give children time for one revision. Assess the way they describe a test and use its result, as well as the finished model. A design that falls can still provide a useful observation.
