- 2. Station: Changes inthe state of matter and chemical reactions First part: Use your knowledge to identify these changes: Write: ● Process that produced the change. ● Is it a physical change or a chemical change? ● Why do you know it? Example: This is a fermentation process. It is a chemical change because a new substance is produced: mould. _____________________________________________________________________________________ _____________________________________________________________________________________ _____________________________________________________________________________________ _____________________________________________________________________________________ _____________________________________________________________________________________ _____________________________________________________________________________________ 2
