98 ! throughout this lesson, you learned about the lives and contributions of key scientists in this area of physics. create a timeline that ties them all together. the timeline does not need to be highly detailed, but it should do the following: include at least the four major scientists covered in this unit: oersted, ampère, faraday, and tesla. include key contributions of each scientist and provide a year, if possible, for those contributions. note any relationships among these and other scientists, especially if one developed something based on the work of another. arrange the scientists chronologically by their first key contribution, not by their birth date.
