Introduction
This term you are a chemical scientist and will be investigating changes to materials that can be reversible and irreversible.
You will be required to:
1. Complete each task within the webquest
2. Demonstrate your learning by completing a written test
3. Research an experiment to demonstrate at our OLW science fair.
Task
To investigate changes to materials that can be reversible and irreversible.
In your year 6 Science folder create a new folder called CHEMICAL SCIENCE TERM 2.
Within that folder create an ASSESSMENT FOLDER THIS IS WHERE YOU WILL KEEP YOUR ASSESSMENT.
Process
TOPIC 1
Learning Intention: You will understand what happens when materials are mixed.

Evaluation
This will be your test. Come and see a teacher when you have completed the tasks and are ready for the test.
Conclusion
After completing your test you will research an experiment you can conduct at our Science Fair which demonstrates a Reversible and Irreversible material. You will need to write the procedure you will be following and can choose your preferred method to present your experiment. Eg; video yourself or conduct it on the day "Live".
