Quick summary: Students investigate the chemical changes required to change raw materials into materials ready for manufacturing. They find out how iron, aluminium and plastics are produced. They use chemical equations that show how raw materials are chemically changed into materials that can be used for manufacturing.
This lesson has been developed as part of the Packaging Covenant Schools Recycle Right Challenge for Planet Ark’s National Recycling Week. Register your lesson or other activities so they can be counted towards the national achievement and to receive other free support materials.
- Students use symbols in chemical equations to show how materials are processed.
- Students explore the processing of raw materials including the use of heat, electricity and catalysts.
21st century skills:
Australian Curriculum Mapping
Year 10 Science:
- Different types of chemical reactions are used to produce a range of products and can occur at different rates (ACSSU187)
- The atomic structure and properties of elements are used to organise them in the Periodic Table (ACSSU186)
Syllabus Outcomes: SC5-16CW.
Year level: 10
Time needed: 50 min
Level of teacher scaffolding: High – assist students with the chemical equations.
Resources needed: Computers, access to the internet including YouTube, scrap paper, scissors and sticky tape.
Digital technology opportunities: Science resources form the internet, interactive periodic table such as periodicvideos.com
There’s an app for that: Periodic Table of the Elements – Standard periodic table of the elements – a necessity for anyone interested in or even exposed chemistry. You can select a chemical attribute and have the entire chart colour coded to plainly show the different elements.
Assumed prior learning: Use of the periodic table, use of symbols to represent elements, have written some chemical reactions as equations.
Keywords: Aluminium, alumina, ferrous, iron, ethylene, polyethylene, anode, cathode, pot, furnace.
