Ms. Le will ok :)
How do a fact and opinion differ?
A fact is a measurement, observation, or statement that can be strictly defined. an opinion is a personal view, feeling, or claim that cannot be proven true or false.

International System of Units (SI)
A tool used to measure lengths and distances
ruler or meterstick
The act of using one or more of your senses to gather information
What are the 3 main branches of science?
Earth, life, and physical
How could you verify that information you read in an ad was true?
You could see if the information had been verified by a trusted source, such as a scientific study.
1 thousand
A tool used to measure the mass of an object
Triple beam balance or Scale
Is a logical explanation of an observation that is drawn from prior knowledge or experience.
Inference
Someone who studies dolphins would be part of which branch of science and WHY?

What would be the length of a paper clip if you rounded it from 4.462 cm to TWO significant digits?
4.5 cm
Is the practical use of scientific knowledge, especially for industrial or commercial use (from lesson 1)
Technology
What is the difference between mean, median, mode, and range?
Mean = average. Median = middle number. Mode = number most often found. Range = highest minus smallest.
What is the difference between a hypothesis and a prediction?
A prediction is a statement of what will happen next.
How is a scientific theory different from an everyday theory?
A scientific theory is an explanation that is based on knowledge gained from many observations and investigations.
An everyday theory is an untested idea or opinion.
Why can't a belief be tested by a scientific investigation?
A belief cannot be proven or disproven using scientific methods because a belief is a personal feeling or opinion.
What is the difference between a description and an explanation?
A description is a summary of observations. An explanation is an interpretation of observations (explains why)
Why is the measurement of a paper clip using a ruler marked with millimeters more precise than the measurement of a paper clip with a ruler marked only with centimeters? (POSSIBLE DOUBLE POINTS FOR A GOOD EXPLANATION)
When a ruler has millimeter markings, you can find the length of a paper clip in millimeters by looking at the marks. Without those marks, you have to estimate the length of a paper clip of millimeters
What is the difference between scientific theory and scientific law? (you won't get negative points if you get this answer wrong)
Scientific theory is an explanation of observations or events that is based on knowledge gained from investigations. Scientific law is a rule that describes a pattern in nature.
Unlike a scientific theory that explains WHY an event occurs, a scientific law only states that an even will occur.
What are the steps of scientific inquiry? (there are 6)
Ask questions, hypothesis, test hypothesis (through investigations), analyze results, draw conclusions, communicate results
How could you change the question " Which pizza tastes better: cheese or pepperoni?" so that it could be answered using scientific investigation?
Change question to "Which pizza is preferred by more students in the school: Cheese or Pepperoni?" and then test this question by conducting a survey.
What is the definition for significant digits?
The number of digits in a measurement that you know with a certain degree of reliability

Binoculars to see objects from far away. Wind vane and anemometer to gauge the wind. Compass to show direction. Streak plate to determine an unknown mineral.
