Step 1: Choose Your Events Remember, you must choose at least six historical events. Within those events, you must refer to contributions by the following six scientists: Ptolemy, Copernicus, Tycho Brahe, Kepler, Galileo, and Newton. (Keep in mind that a single historical event can easily include two or more references to scientists.) Choose your events based on what interests you most and what you’d like to spend a little bit of time learning more about. Step 2: Plot Your Events on a Timeline You may create either a digital or a hand-drawn timeline on paper or poster board. For inspiration, search for images of timelines online. As you’ll be displaying your timeline, make sure to check out at least two timelines that appear in a public space such as a science museum. Note the features of the timelines and make sure you understand all the text. Consider which elements and text you’d like to include on your own digital or hand-drawn timeline. Whichever you decide, draw your timeline and plot each of your six events on the line. For each event, write the year (or range of years) in which it occurred and two facts about it: one fact can be from the unit text and the other you need to find through some quick research. For example, if you choose the Aztec New Fire ceremonies as your event, you would plot it between 1100 and 1521 CE, and list one fact from the unit as well as one fact you found on your own. You will cite your sources in a separate document when you are finished, so keep track of the resources you use and make sure they are reputable (printed works or from .org, .gov, .edu, etc. websites). State your facts in complete sentences, tying them together with transitions if needed, rather than writing bullet points below your event. This means your statement of facts may be longer than two sentences per event. Make sure that your timeline does not take up all of the vertical space on your page, as you will need space at the bottom of your page for the next step. A rectangular box representing a landscape-
