Acids and alkalis: a concept cartoon | 11-14 years
Check your students’ understanding of acids and alkalis using this lesson plan with downloadable activities for 11–14 year olds.
In this activity, students are presented with a concept cartoon about an acid spill, then work individually and in groups of three to consider suggestions about how to deal effectively with such a spillage.
The cartoon is designed to check on the following concepts and misconceptions:
- The difference between neutralising and diluting when water is added to an acid.
- The idea that alkalis such as antacids somehow ‘break down’ acids.
- The idea that an indicator reacts with and therefore uses up an acid.
- The idea that an alkali such as sodium hydroxide will react with an acid to make it neutral.
- The addition of excess alkali to an acid produces a solution that is also hazardous.
