Teaching Year 7 students about acids and bases can be tough. Here are some common problems and simple solutions:

1. Safety Concerns: Using acids and bases can be risky.

   • Solution: Work with weaker solutions and always wear safety gear like goggles and gloves.

2. pH Measurement: Figuring out pH levels can be tricky.

   • Solution: Use pH strips or meters. They give clearer results than just using color indicators.

3. Reaction Observations: Students might find it hard to see smaller reactions.

   • Solution: Choose fun and exciting reactions, like mixing baking soda and vinegar, to show what happens.

4. Data Interpretation: Understanding the results can confuse students.

   • Solution: Give them guiding questions. This will help them connect what they see to the properties of acids and bases.
