This is everything you need to give your chemistry students a nice background on the history of the atom! Students use skills of synthesizing informational text, organizing pieces of information into groups and then into a chronological order, and displaying the information in a clear and creative way.
This project covers: Democritus, Aristotle and "the Death of Chemistry", Dalton, Thomson, Rutherford, Bohr, and the Modern Cloud Theory.
I like to show this Ted Ed video before we begin: http://ed.ted.com/lessons/the-2-400-year-search-for-the-atom-theresa-doud#watch
My students do this project in pairs. I provide them with 11" by 17" white construction paper for the "posters". They end up being the perfect size to fit all of the information/pictures, and they look great hung up in my classroom and are not too big!
Copy one "Information Book" (it looks fine in Black and White - I copy it back-to-back, put the pages into four plastic sleeves, and bulldog clamp the pages for use each year) and one set of the Directions and "Everything You Need to Make an Atomic Theory Timeline" per group or pair of partners.
The students read through the Information Book, cut out the "Everything You Need" pages and organize the images and information boxes into their own timeline. I encourage them to make the poster colorful in order to separate the information that belongs together. Some students get creative by decorating with ways to remember the models: "chocolate chip cookie dough" around Thomson's information or "Legos" around Democritus'.
There is a page containing 8 multiple choice questions and the project rubric. The students should answer the questions after completing their timeline, and tape the page to the back of their project to make grading easy for you! I think this project is a great way to make the students responsible for the learning, rather than making them sit through a boring PowerPoint!
If your students are not clear on the general concept of a scientific theory, please consider using my Differentiating Between Scientific Theories and Scientific Laws Group Activity
as an introduction before beginning the Atomic Theory project!
Thanks for looking!
