Activity 1 - Acid rainSubtopic 8.5 - Acid deposition
Subtopic 3.2 - Acid/base character of the oxides
NOS statement 5.1 - An understanding of the nature of science is vital when society needs to make decisions involving scientific findings and issues.

Time: 1 hour.
Task: At the beginning of 2016, London exceeded its yearly NO2 emission after just a week. The production and impact of these gases includes some reasonably complicated chemistry that may not be easily understood by many. Create a group poster/blog that explains the chemistry involved as simply as possible .

Activity 2 - Theories of acids
Subtopic 8.1 - Theories of acids and bases
NOS statement 5.1 - The evidence is used to develop theories
Time: 5 min.
Task:
a. Look at the different groups of "acids" below. Assume that the groups are ordered in chronological order of being classified as "acids". In each case decide what can be deduced about acids (using only their formulas) and which of the previous deductions can then be discarded.

Subtopic 8.1 - Theories of acids and bases
NOS statement 5.5 - Another key issue is the use of appropriate terminology.
Time: 10 min.
Task: The image to the left shows 7 different definitions of an acid. Use a Venn diagram to represent them.
