2). Group work: Do you know how to prove a new idea in scientific research? Discuss in small groups the stages in examining a new scientific idea. What order would you put them in?
draw a conclusion think of a method collect results make up a question
find a problem analyse the results find supporting evidence repeat if necessary
2. While-reading:
1).Predicting:
Introduce the title of the passage—John Snow Defeats King Cholera.
