LEARNING GOALS:
In this unit students explore the historical development of
understandings of atomic structure. Students model an atom
according to currently accepted understandings. They will identify
patterns in atomic structure that allow prediction of the products
of chemical reactions and are reflected by the periodic table. They
recognise that new substances are formed during a chemical
reaction, and are able to list and describe the possible changes that
can be observed during a chemical reaction. Students will be able
to use the particle theory of matter to explain what is happening
during a chemical reaction, and relate this to the Law of
conservation of matter. They identify the work of selected early
researchers into natural radiation and examine the concepts of
isotopes and half-life. They explore practical applications of natural
radiation.

S SUCCESS CRITERIA: THE STUDENT WILL BE ABLE TO DO THE
FOLLOWING:
 Describe the structure of atoms in terms of the nucleus,
protons, neutrons and electrons
 Describe and distinguish between chemical and nuclear
reactions in terms of conservation of mass
 Describe and distinguish between chemical and physical
changes
 Describe observable changes that occur during a chemical
reaction
 Describe reactions using word equations
 Give examples of how radioactive elements are used in a
range of applications, e.g. dating of rocks, medicine and
industry
