Close Reading: Paintball- Chemistry Hits Its Mark

Do a #CUBS reading of the article. Use your knowledge of the gas laws, as well as evidence from the text to answer the

following questions.

# = write hashtags that summarize main points, make connections to what you’re learning, or define terms

C = circle key terms

U = underline main ideas (focus on what will help you complete your synthesis)

B = box any unknown words, or confusing concepts

S = synthesize (in this case it’s answering the questions)

1. The article talks about the use of a copper burst disk that pops off, if the pressure inside the canister gets too high.

What is causing the pressure in the canister and why would releasing some of the gas prevent an explosion?

2. Explain what is being shown in the graph to the right of the first paragraph (what are the variables, how are they

related?).

3. In the definition of Boyle’s law given in the article, what does “inversely proportional” mean?

5. Write a short paragraph, or draw a cartoon summarizing how Boyle’s law is used to explain how a paintball is shot

forward.
