Activity 1: "Shade balls"
Subtopic 17.1 - The equilibrium law
NOS statement 4.8 - Science has been used to solve many problems and improve man’s lot, but it has also been used in morally questionable ways and in ways that inadvertently caused problems.
Time: 10 mins.
Task: Read the article below about the use of "shade balls" to reduce the rate of evaporation of water reserves. It is being used as one solution to current drought in California. Can you think of any problems that could be related to the use of these 96 million plastic balls?

Task: In pairs, select one of the sources below and summarise Fritz Haber's contribution to science in a maximum of 3 sentences
Compare both summaries and discuss the following points:
- Was he a good or bad scientist?
- Did he have a positive or negative impact on humanity?
- Which contribution had the greatest impact?
- Did he deserve the Nobel prize?
- What are the pros and cons of scientific development?
Extension: Henry Le Chatelier also worked on the problem of ammonia production and was very close to reaching the conditions that Haber found. How might this have impacted history differently? Hint: Le Chatelier was French.
