"Two Truths and a Lie" is one of the activities that we did during the Science Workshop at COABE-PAACE. It is a general teaching strategy which you may have used before. Students generate three statements about virtually anything. Two statements are are true and one is a lie. Then, they challenge classmates to identify the lie.
We used the activity to really delve into the question: "What does this graphic say?" We began with a simple-looking graph on the Percent of Adults Receiving Influenza Immunization in 1999-2000 for people with asthma. The graph can be found on the CDC here:
What do you think of my statements? Which statement is a lie, and why?
Statement 1: Adults with asthma, age 65 and older, are the only age group to have a fewer percentage of people immunized in 2000, compared to 1999.
Statement 2: The number of people with asthma, age 50-65, who were immunized in 1999 is over 40,000 people.
Statement 3: The largest percentage of all adults with asthma who were immunized occurred in 2000.
We had a lot of fun doing this and, in some cases, ended up with two lies and one truth!
