DM ie Names; RUMBER FOUR? ee Atomic Theory Timeline! Re Directions: 1) Read the information about the scientists and theories that have developed over time about matter and the atom in the Atomic Theory Timeline information packet. YOu LEFT AT BLANK, CHOAFIEWD. 2) Cut out all of the scientists’ names, information boxes, scientist pictures, atomic models, and analogies and organize them by date/theory. 3) Ona 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: 1803 1897 1908 \ < t t > Or it may be more like a “journey” (you can be creative with this): 1803 ; ao 1908 rs ; ‘> Ser . *B: ao Sp Se ned 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 8 included questions and look over the rubric to see how this project will be graded. Tape the Questions/Rubric page to the back of your timeline before submitting it. Atomic Theory Timeline Questions and Rubric Names Period Please choose the correct answer to the following questions.
