50 point summative project

Purpose of the Project:

A study of the development of modern atomic theory illustrates how theories can change as new discoveries are made. For this reason, we normally study atomic theory in its historical context. You will discover through your research: Who thought of the atom first, how the model of the atom has changed through time, how the model looks today, and which people are responsible for the greatest changes in the atomic model.

YOUR TASK:

Research each of the scientists. (Use you text book, our website, and the Internet.)

You will be creating a timeline, on ½ sheet of poster board to communicate your findings

A)Draw a colored timeline with dates clearly labeled

B)Neatly, glue all the information on your timeline

C)Add color or other decorations to make your timeline visually interesting.

D)Refer to the rubric to ensure that you add all of the information required

E)You may choose to add other appropriate information and/or pictures you find during your research.

F)Turn in project on time with rubric glued or taped to the back.

RUBRIC Name______

Correct experiment with each scientist_____/ 10

Correct findings with each scientist_____/ 10

Correct Model with each scientist_____/ 10

Neat and Visually appealing_____/ 8

Rubric glued or taped to the back_____/ 2

BUILDING YOUR TIMELINE:

For each of the scientists listed below, you will be providing the following information:

Research the development of modern atomic theory. You may use the Internet, your textbook, or our website. The goal is to place the scientists in correct order based on the atomic model they are credited with. 10 points

Match the correct experiment with each scientist. Photos have been provided. You may use them or find your own photos. 10 points

The significance of their experiment – observations made and what they discovered/what the scientist is known for(such as discovering protons). Brief statements of each scientist’s findings have been provided. You may use these statements or type up your own. 10 points

The correct model is matched up with each scientist. Please note, as can be seen in the below table, there are more scientists than models. This is due to the fact that while the scientists contributed to our understanding of the atomic model the actual model did not change. 10 points

Neat, colorful, easy to read timeline 8 points
