Chapter 14 - Atomic Theory – Scientist Timeline Below is a list of individuals that have made significant contributions to the concept of the atomic theory. Your task today is to match the scientist with the appropriate description. Some scientists will have more than one description associated with them. Activity 1: Timeline Under each scientists name there is a line. On each line, write the year that they did their work. You should be completing the research for Activity 2 while you do this activity. These scientists did many things – some having to do absolutely nothing with the atom. So, be sure that the date you record – relates to the atom. List the scientists in chronological order based on their discoveries related to the atomic theory. Activity 2: What the scientists did. Cut each of the scientist rectangles on the 2nd sheet of paper Spread them out across your work table. These are going to be your headings. Next, cut each of the “things they did” descriptions. You are going to research each description and determine which heading / scientist the item goes under. Once you have all in place – ask your teacher to check it.
