This Subtangent activity uses information from the Hubble space telescope to emphasise the need for accurate measurements and the costs involved when things go wrong.
There are demonstrations of measuring lengths and angles before asking the students to try for themselves.
An interactive ruler and protractor are provided in this activity. There is only one line and one angle for the students to measure. The answers are given.
HEALTH and SAFETY
Any use of a resource that includes a practical activity must include a risk assessment. Please note that collections may contain ARCHIVE resources, which were developed at a much earlier date. Since that time there have been significant changes in the rules and guidance affecting laboratory practical work. Further information is provided in our Health and Safety guidance.
