3 branches of science

Life Science: study of living things and their relationship to one another and the environment.

Physical Science– study of matter and energy… Matter( chemistry) and energy is part of the physical science 3. Earth Science– study of Earth , its history , its changes, and its place in the universe.

Scientific method http://studyjams.scholastic.com/studyjams/jams/science/scientific-inquiry/scientific-methods.htm

7 Steps to the Scientific Method 1) State the _______________) purpose 2) Research it, and get _______________. information 3) Form a Hypothesis. ( educated guess) 4) Perform an _____________________ experiment 5) Collect Data. (Observations and Results) 6)Form your ____________________ conclusions_ 7) the experiment. Repeat

Every experiment must have a __________________and a _______________. Control- part of experiment that stays the ________________ Variable- part of exp. being __________________ Independent V- causes a _____________in something being tested. ( cause ) Dependent V – the part in the experiment that ___________( effect ) Theory--- A theory is the most logical explanation for something that happens in nature. Law— A theory becomes a law when it is well accepted and well tested by the sc. Community.

So here’s a question: If two people travel the same distance, from A to B, at the same time, and one is walking, while the other is running, who will get “wetter” if it is raining? How would you solve this problem using the Scientific Method?

How would you get the volume of a cylinder? http://www.brainpop.com/math/geometryandmeasurement/volumeofcylinders/

All # must be between # 1 and 10. Scientific Notation To reduce the number of zeros in very big and very small numbers, you can express the values as simple numbers multiplied by a power of 10. All # must be between # 1 and 10. scientific notation. 103 = 1,000 102 = 100 101 = 10 100 = 1 10-1 = 0.1 10-2 = 0.01 10-3 = 0.001

The speed of light is about 300,000,000 m/s In scientific notation the speed of light is 3.0 x 108 On your own: Write the following measurements in scientific notation. a. 800,000,000 m b. 0.0015 kg Write the following measurements in long form. a. 4.5 x 103 g b. 1.99 x 10-8 cm
