Reversible & Irreversible Changes
Australian Curriculum: Changes to materials can be reversible, such as melting, freezing, evaporating; or irreversible, such as burning and rusting (ACSSU095)
Investigating Solidification
Learning Intention: Understand
the changes that occur during solidification.
Success Criteria:
Success Criteria:
- I can explain what solidification is.
- I can contribute to a discussion about which variables should be changed and which should be kept the same to create a fair test to observe materials during solidification.
- I can contribute to a discussion about what should be measured during the fair test.
- I can describe the changes to a material during solidification.
Investigating Melting
Learning Intention: Understand the changes to a material during melting.
Success Criteria:
I can identify ways in which materials change state
I can describe the changes to a material when it melts
I can think about if and how the melting can be reversed based on my own experiences
I can create a visual and informative display to describe how something melts and how the change can be reversed.

Investigation Evaporation and condensation
Learning Intention: Understand how a liquid changes into a a gas (evaporation) and how it can be reversed.
Success Criteria:
Success Criteria:
- I can explain what evaporation is.
- I can explain what condensation is.
- I can contribute to a discussion about setting up a fair test to observe the effect of temperature on condensation.
- I can use the equipment and materials safely.
- I can explain how a liquid changes into a gas and how it can be reversed.
