Theme: Science – Chemical Sciences
Level: 3 & 4
Students will investigate the changes that occur between solid and liquid matter when adding and removing heat.
- Discuss prior knowledge of matter and its states.
- Investigate the special properties of solids and liquids.
- Classify materials based on state of matter and recognise that some materials do not fit nicely.
- Explore how different solids can be bent.
- Observe surface tension in liquids.
- Investigate the change in viscosity of a liquid due to temperature.
- Use a thermometer to measure and compare temperatures.
- Compare evaporation of different liquids.
- Test the melting point of wax, chocolate, citric acid and sugar.
- Conduct experiments safely in a group.
Victorian Curriculum: Content Descriptions
- A change of state between solid and liquid can be caused by adding or removing heat (VCSSU059)
- Natural and processed materials have a range of physical properties; these properties can influence their use (VCSSU060)
- Science knowledge helps people to understand the effects of their actions (VCSSU056)
- With guidance, identify questions in familiar contexts that can be investigated scientifically and predict what might happen based on prior knowledge (VCSIS065)
- Suggest ways to plan and conduct investigations to find answers to questions including consideration of the elements of fair tests (VCSIS066)
- Safely use appropriate materials, tools, equipment and technologies (VCSIS067)
- Use formal measurements in the collection and recording of observations (VCSIS068)
- Use a range of methods including tables and column graphs to represent data and to identify patterns and trends (VCSIS069)
- Compare results with predictions, suggesting possible reasons for findings (VCSIS070)
- Reflect on an investigation, including whether a test was fair or not (VCSIS071)
- Represent and communicate observations, ideas and findings to show patterns and relationships using formal and informal scientific language (VCSIS072)
