The South Australian Chamber of Mines and Energy is acknowledged as the provider of this resource. Radiation is all around us. It is energy travelling through space. Heat, light and sound are familiar to our senses, ultra-violet waves gives us sunburn, and radio waves require some instruments to ...
This graphic organiser is used to identify similarities and differences between three types of radiation – alpha, beta and gamma. Educational Value Statement Identifies three different types of radiation: alpha, beta and gamma Explores similarities and differences in radiation properties Can be ...
This worksheet explains how isotopes can become unstable and investigates the number of protons and neutrons in example isotopes. Students then use the ANSTO Atom Builder online to construct isotopes and record if they are stable or unstable. The Australian Nuclear Science and Technology Organisation ...
This worksheet introduces the atom and uncovers the properties of protons, neutrons, electrons, ions and isotopes. It also contains a table allows for comparing the mass and charge of protons, neutrons and electrons, and their relation to elements in the periodic table. Educational Value Statement ...
