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
