Blizzard bag 1 Physical Science

Blizzard Bag #1

Scenario:

A Puzzle with Many Pieces: Development of the Periodic Table

Dmitri Mendeleev is credited with the development of the periodic table. The story illustrates interpretation of data, the importance of standardized system of measurement, and communication among scientists. However, Mendeleev did not accept theories regarding radioactivity and subatomic particles which were later incorporated in corrections to Mendeleev’s Periodic Law.

Informational/Explanatory

After reading information on the historical development of the periodic table and other resources as needed, write a report that summarizes the development of the periodic table and describes the link between development of scientific laws and theories. Support your topic with evidence from your research.

Explain the scientific method.

In your explanation, be sure to include:

• the steps of the scientific method

• different types of variables and control

• purpose of the steps

• why a conclusion is important

Blizzard Bag #3

The three common phases of matter are solid, liquid, and gas. An ice cube is a solid but it can be physically changed into a liquid and a gas.

Think about the ways the three phases of matter can be physically changed.

Now, explain to the reader of your paper, how a solid ice cube can be physically changed into a liquid and then a gas.
