Year 9 Science
Chemistry: Radio-isotopes
If you have any questions or requests for assistance regarding your research, please contact your Teacher Librarians.
This page has been created by your Teacher Librarian to support Year 9 Science students with the Chemistry SHE task on Radio-isotopes.
The sources of information listed below are to get you started.
You may still need to locate and select sources of information yourself via a free internet search. Ensure you evaluate sources of information first using the CRAAP test before deciding to use the information in your work . (Tip: validate the expertise of the author first). To develop your search skills refer to the Advanced Search Tips section.
