Flame testing

Flame testing: What would be considered safer for Year 8 students attempting flame testing of chemicals?  Using a small quantity of solid chemical in a flame on a metal loop, or a chemical solution sprayed into the flame?  Or would this be better carried out as a teacher demonstration?

W.A.S.P. Year 8 – Rocks and minerals

This online teaching package provides hands-on activities with teacher support materials to support the Year 8 Earth and Chemical Sciences components of the Australian Curriculum.

The activities are organised into three topics:

  1. Why Study Rocks?
  2. Rock Cycle
  3. Identifying Common Rock Types
  4. Rocks and Minerals as Resources
  5. Aboriginal Perspective

TED Ed - Just how small is an atom

This online resource examines the relative sizes of atoms, neutrons, protons and electrons.

The resource is a TED Ed video (5:27 min) which could be used as an introduction to a unit, or to consolidate understanding on subatomic particles.

It also examines the density of an atomic nucleus in terms of six million cars squashed into a 1-metre square box. 

Rock, paper, scissors - Science by Doing

This resource is an inquiry-based learning sequence of hands-on activities, digital interactives, animations and videos that cover materials, properties, the periodic table and elements, states of matter, the kinetic theory of matter, compounds, mixtures and alloys. It also examines physical and chemical reactions with rust as a case study.

Exploring atoms - atom bingo

This online resource helps consolidate student's understanding of atomic structure through a bingo-like game.

The game involves building atoms from their sub-atomic components, including filling in the electron shells.

They can play individually or against each other (on different computers) to construct specific atoms in order to be the first to reach BINGO!

The repetition of building the atoms' structure is designed to consolidate the student's understanding of the structure of an atom and the differences between the atoms of different elements.

The Elements: Elements and compounds assessment

This online resource is an assessment item to identify compounds and elements.

The resource tests a student’s ability to identify compounds and elements and their properties through the use of an activity that deconstructs common materials found in the real world.

At the end of the assessment, a report is created that can be printed and handed to a teacher.
