Scientific Method
An organized plan for gathering, organizing, and communicating information
Step 1: Ask a question.
Step 2: Make an observation
Step 3: Form a Hypothesis
![Page 4: DO NOW Without using your book what are the three branches of Natural Science? Earth and Space, Life, Physical](https://reader035.vdocument.in/reader035/viewer/2022070407/56649e2a5503460f94b17f37/html5/thumbnails/4.jpg)
Scientific Method
Step 4: Test your hypothesis (Experiment)
Step 5: Analyze Results
Step 6: Draw Conclusions
Step 7: Communicate results and develop a Theory

Theory versus Law
Scientific Theory: a well-tested explanation for a set of observations or experimental results. This is created when a hypothesis has been supported
in repeated experiments
Scientific Law: describes an observed pattern in nature without attempting to explain it.

Scientific Models
Make it easier to understand things that might be too difficult to observe directly.
![Page 7: DO NOW Without using your book what are the three branches of Natural Science? Earth and Space, Life, Physical](https://reader035.vdocument.in/reader035/viewer/2022070407/56649e2a5503460f94b17f37/html5/thumbnails/7.jpg)
A way of expressing a number between 1 and 10 and a power of 10.
Can be used for very large or very small numbers.
400,000,000 can be expressed 4.0 x 108
0.000000007 can be expressed 7.0 x 10-9
Scientific Notation

50,000,000= 5.0 x 107
900,000= 9.0 x 105
0.00000003= 3.0 x 10-8
0.002= 2.0 x 10-3
23,000,000,000=2.3 x 1010
450,000= 4.5 x 105
Write the Scientific Notation for the following numbers
![Page 9: DO NOW Without using your book what are the three branches of Natural Science? Earth and Space, Life, Physical](https://reader035.vdocument.in/reader035/viewer/2022070407/56649e2a5503460f94b17f37/html5/thumbnails/9.jpg)
When you are asked to multiply two numbers in scientific notations, multiple the numbers in front and then add the notations.
(3.0 x 109) x (5.0 x 103) = 15.0 x 1012 =1.5 x 1013
Multiplying

When you are asked to divide two numbers in scientific notations, divide the numbers in front and then subtract the notations.
(9.0 x 109) / (3.0 x 103) = 3.0 x 106
Dividing

Precision- gauge of how exact a measurement is. The more significant figures in a number the more
precise the number. The precision of a calculation is limited to the least
precise number in the calculation.

Measuring Temperature
Thermometers: Bulb thermometers consist of a sealed, narrow glass
tube, called a capillary tube. As the temperature changes, the volume of the liquid changes.
K= oC + 273 F= 9/5oC + 32.0o

Slope = Rise/Run
Direct proportion- ratio of the variables is constant.
Inverse proportion- relationship where the product of the two variables is constant.
