TERC researchers Andee Rubin and Gillian Puttick, with collaborators, recently published “Using Existing Data to Investigate Ecosystem Change” in The Science Teacher. The article describes how ninth-grade students used data to investigate the rise of wildebeest and buffalo populations in Serengeti between 1960 and 1975. Students engaged in data practices, including interpreting scatterplots and evaluating evidence. The article also includes strategies for teachers integrating data analysis into scientific sensemaking. Download the article here.
