What Pluto observations did not help convince scientists to change Pluto's status from that of a planet?
The discovery of Pluto's 3 moons.
Why have scientists revised the a atomic model many times?
they could discover a new atom and it would change
What are 3 observations that are signs of a change?
cool
What is the result in fire prevention programs?
A change in community compositions because fires are natural disturbances that maintain the community structure
How does changing the amounts of reactants in a chemical reaction change the chemical compositions of the products?
Yes, it is possible; for example complete or not complete burning.
What Pluto observations did not help convince scientists to change Pluto's status from that of a planet?
The discovery of Pluto's 3 moons.
What cause scientists to change or replace the modern atomic theory?
If new observations do not fit exactly with the current theory.
When would scientists need to change a theory?
Scientists had made observations that did not fit exactly with Dalton's theory. Scientists changed the atomic theory to include this new knowledge. While the modern atomic theory is based on Dalton's theory, it is also very different.
Prediction need to change when?
observations change
Why have scientists revised the a atomic model many times?

What are 3 observations that are signs of a change?
cool
When do predictions need to be revised?
observations change.
What are two observations you might make when a physical change occurs?
change in shape and color.
Why have scientist change their ideas on the model of the Atom?
There has been more and more observations about the atom that has changed it since then. They revised it to explain the observations.
What are two types of qualitative observations in chemistry?
Color Change and Smell
How did the scientists revolution change the way scientists did their work?
They relied more on evidence.
How would the compositions of air change if there is a large increase in the air burning fuel?
There will be an accelerated greenhouse effect on the earth.
