I used this 2-page worksheet with my high school students to interpret graphs and visual data. It goes through all parts of the graph, and asks students to interpret data and trends in the data. Students are asked to describe the scientific method might have been gathered. Students are then asked about implications of the data and how the data might have been used.
You will receive a 2-page PDF. If you have any questions - I'd prefer you ask me BEFORE purchasing rather than leaving less than flattering feedback after purchasing. :)
