Atomic History Quiz

Using the information you just learned, how do you think the 'change' from the billiard ball model to the Plum Pudding model demonstrates the nature of science?

• Not sure

• Some really smart people figured it out

• Our understanding of the world changes in time because of technology and improvements in data

• what is the nature of science?

Give each of the models and a brief description about why it was important.
