The wider beam held more than twice the load in both chosen trials.
2 results support this answerHow a lesson works
Students know what comes next. Teachers can check the work without opening separate files.
Start with a question students can investigate.
Decide what to change, what to measure, and what to keep the same.
Collect results or open the included data, then look for patterns and problems.
Make a chart and use specific results to support a conclusion.
Use teacher feedback to make the explanation clearer and stronger.
Ready-to-use investigations
Each one includes student directions, data, charts, and a teacher review page.

For teachers
Check who has started, who is ready for feedback, and who needs to make changes. Open a student’s work to see their answer and chosen results.
The accordion bridge held the most because the folds spread the load.
