Tree Height Investigation, Years 9–10
Students conduct virtual fieldwork by measuring ground distance and angle of elevation, choosing the correct trigonometric ratio, calculating the tree's height and comparing the result with the revealed height. The full interactive is available to licensed Education Universe users.
Years 9–10Guided investigation
Learning outcomes
- Use angles of elevation in practical problems.
- Choose and apply a trigonometric ratio.
- Compare a calculated result with a measured value.
Teaching guidance
Discuss sources of measurement error and ask students how they would improve their estimate in real fieldwork.
