This printable includes stories about four scientists: Billy the Botanist, Cindy the Chemist, Ned the Neurologist, and Phil the Physicist. Each story is about an experiment performed by one of these scientists. Students are asked to read the story and find the scientist's hypothesis, independent variable, dependent variable, and one of their constants. Students also judge if the scientist is a good scientist or not. (Billy, Cindy, and Ned are good scientists, but Phil is not.)
I used this in my classroom after spending two days teaching the basics of experimental design. (Variables and hypotheses) We also talked about what makes a scientist a good scientist. (A good scientist follows rules, is careful, is safe, shares their findings, etc.) The students enjoyed reading the stories, although they did need some help with knowing the scientific disciplines. (Neurology especially!)
I allowed my students an hour for this, and most were able to finish the assignment when working with a partner.
The activity is four pages long. An answer key is included.
Thanks for looking! I hope you find this useful!
