Atomic History Presentation

Atomic History Presentation

As a group of three, you will research an assigned piece of history involving the atom. The model of the atom as we know it comes from the contributions of many different experiments and many different scientists. Your group will become an expert on a small piece of atomic history and present your understandings to the class.

Step 1: Look at the notes scaffold on the opposite side (this can also be found on the Quia class webpage). Research your assigned person(s) and experiment(s) to determine what belongs in the missing blanks. When your group as filled in all of the blanks, have your teacher check your work.

Step 2: Label any diagrams and complete any assigned problems for your section.

Step 3: Create a presentation (PowerPoint, Google Slides, Prezi,) that includes the information on the notes scaffold. You should also include your labeled diagram and relevant pictures involving your topic. (See presentation rubric for what should be your presentation).

Possible slides to include:

1)  Who is this person?

2)  What experiment(s) did the person set up (including diagrams)?

3)  What were the results of the experiments?

4)  What conclusions were drawn from the experiment?

Step 4: Be sure to go through your information so that you are able to explain it. On your assigned day, give your presentation to the class.

Step 5: After you have given your presentation, you will grade each of your group members using the group member rubric.
