3. Lesson 1: Comprehend Scientific Presentations
Main Idea  topic
Details, facts, and evidence
The earliest americans traveled from Asia to North America. These americans were called “Native Americans”. They were the first to settle, until an explorer name Christopher Columbus arrived. There were many explorers traveling and discovering the world in the late 1400s. In 1492, CC set out across the Atlantic ocean. He was rejected by multiple Kings, and finally went to Spain and convinced them finance his trip. At first he assumed he found India and later on it was discovered that he actually found the “new world”.
After this discovery, European nations set out to conquer what they could. In other terms, they discovered new “colonies”.
Was about power, wealth, and place to live

5. Lesson 2: Use the scientific method
Dependent variable  the phenomenon you’re studying
Independent variable  a factor that you believe might be affecting the phenomenon
Taking samples: for step #2
sample  portion of the entire thing or population
To make an inference on entire population, have guidelines
concern: sample may not be representative of entire population
-an unrepresentative sample introduces bias
-to prevent this, collect large enough sample size to reduce the probability

6. Lesson 2: Use the scientific method
Randomization  increase the chance of valid results
Control group  does not receive any treatment

7. Lesson 3: Comprehend Scientific Presentations
The test require you to recognizing or citing specific evidence to support a conclusion.
Conclusion or scientific theory  a substantiated explanation of the natural world
Other questions will ask to make predictions  based on evidence or data that the test provides to you based on trends  forecast

9. Lesson 5: Use statistics & probability
Math in the science section:
-Central tendency  average, median, mode, range
-Independent and dependent probabilities
-counting techniques for combinations and permutations

10. Lesson 6: Construct short-answer responses
You will need to write 2 written responses
2 writing tasks:
1. cite specific evidence
-complete & well developed explanation
-specific facts, details, or evidence from source material
2. design a scientific experiment
-clearly stated hypothesis
-well-formulated design of how the experiment would be conducted
-logical method to collect data
-sound criteria for evaluating the results in relation to the hypothesis
