Exercises with feedback
MAKE SOMETHING YOU CAN EXPLAIN
Your practical challenge
Draw two bridge designs and a results table. Test with an adult or make a clearly labelled test plan.
These ticks are your self-review. They do not automatically assess project quality. Ask an adult or partner to review what you can show.
Use the skill in a new situation
Repeat a trial and look for variation.
