Identifying signs of a chemical reaction can be tricky. Here are some common signs to look for:

• Bubbles: Sometimes, gas forms during a reaction and looks like boiling.
• Color Change: Sometimes, colors change a little, and those changes can be hard to see.
• Temperature Change: Heat can change, but it doesn’t always mean a reaction is happening. It might just be the temperature around it.

To make sense of these signs, it’s important to observe closely and do controlled experiments in a lab. Keeping a detailed record of what happens during the reactions can really help you notice and understand these signs better.
