Numeracy: Graphing and Radioactivity

Activity
This activity is a worksheet to teach half-life to students as well as recalling graphing and numeracy skills. This activity also has a very small research component, allowing students to have an element of choice and adding interest to the task. The worksheet itself is very highly scaffolded, so students will hopefully not become confused whilst working through the sheet. This worksheet will also be done in class, so students who are struggling will have a chance to ask for help. If some students finish their work early, they will be encouraged to pick another element and graph that, so they will be able to conclude for themselves that radioactive decay follows the same pattern, regardless of the length of an isotope's half-life.

Syllabus Dot points Covered
CW1 d. identify that natural radioactivity arises from the decay of nuclei in atoms, releasing particles and energy
WS7.1 Students process data and information by:
a. selecting and using a variety of methods to organise data and information including diagrams, tables, models, spreadsheets and databases
