Names:____________________________ __________________________________ Make an Atomic Theory Timeline! Directions: 1. Read the information about the scientists and theories that have developed over time about matter and the atom in the Atomic Theory packet. 2. Cut out all of the scientists’ names, information boxes, scientist pictures, atomic models, and analogies, and organize them by date/theory. 3. On a separate sheet of paper, design a timeline that includes these dates: 400 B.C., 300 B.C. to Early 1800s, 1803, 1897, 1908, 1913, 2000 Your timeline may be straight like this: Or it may be more like a “journey” (you can be creative with this): 4. For each of the seven dates, arrange and glue the correct scientist name and picture, atomic model, analogy and additional information (there are two or three information boxes per theory). 5. Make your timeline look great! Give it a title, use crayons or colored pencils to decorate the dates and/or names, and maybe add boxes or bubbles around the information for each date. 6. Answer the questions on the back of this sheet and look over the rubric to see how this will be graded. 1803 1897 1908 1803 1908 Atomic Theory Timeline Questions and Rubric Names ____________________________________________________________________ Period ____ Please choose the correct answer to the following questions.
