You should know all the vocabulary definitions well enough to use them for the rest of the year. At any time, any of these vocabulary words may appear on any test or quiz. Make sure that you know these! Use flash cards, or the flash card app to help you review them. The definitions are still on my website.

4. Performance goals: Understand and use the science vocabulary
Be able to explain the difference between Laws and Theories in science.
Identify variables in an experiment
Tell what is the difference between the independent and dependent variable and identify them in an experiment.
Why do scientists use the International System of Units (SI)
What causes measurement uncertainty?
What are mean, median, mode and range?

5. Levels of understanding
On one of the lines on the left of the box, write today’s date 10/27 and give yourself a rating
1- no understanding
2 – understand some, but not all
3 - I understand most of this!
4 – no worries! I got this!

6. 1. What is scientific inquiry?
Science is the investigation and exploration of natural events as well as the knowledge that results from those investigations. Scientific knowledge is gained from observations, careful investigation, publication, debate, and confirmation within the scientific community.

7. 2. How do laws and theories differ in science?
A Law in science is a pattern in nature. It can not be broken like when we talk about laws made by the government!
A Theory in science is an explanation based on knowledge gained from many observations and investigations. Theories in science have multiple lines of evidence, have been tested over time and are accepted as “true” although they may be modified as new evidence or technology reveals new information.

8. Unlike a scientific theory that explains why an event occurs, a scientific law only states that an event will happen.
For example: Newton’s law of gravitational force does not explain why the object moves toward Earth when dropped, only that it will.

9. 3. What is the difference between fact and opinion?
Facts can be verified and everyone could find out if it was true or not. For example, the temperature outside at a particular time and place (like weather) can be verified.
An opinion can not be proved. Opinions, beliefs and feelings are not usually investigated by science.

10. 4. How are the independent and the dependent variables related?
The independent variable is changed by the experimenter (scientist) to see if it affects the dependent variable.
The dependent variable is measured or observed to see if the changes in the independent variable affected the outcome.

11. 5. How is science inquiry used in real life?
Science is used to discover or reveal events that we do not know about.
In lesson 3, the Iceman was examined by scientists. They discovered many things about someone who lived over 5,000 years ago.
Science process skills were used: observation, hypothesis, predictions, inferences, tests and evidence to make conclusion.

12. Research on the Iceman and the artifacts surrounding him helped scientists to understand how he died. Scientific inquiry often occurs over years and years as different scientists test different hypothesis and adjust old conclusions. The story of the iceman shows that science is active and puts together many pieces of information to get the most accurate conclusion possible.
We will never know exactly what happened, but we can use the evidence (like pollen) to infer what occurred.

13. 6. Why is it important for scientists to use the International System of Units?
The International System of Units (SI) is useful to scientists so that everyone is using the same measurements to work on problems.
For example, the International Space Station has components made around the world, it is useful, and simpler to have them all the same!

14. 7. What is measurement uncertainty?
Measurement uncertainty occurs because no scientific tool can provide perfect measurement.

15. 8. What are mean, median, mode and range?
Mean – is an average of a number set. You add all the numbers together and divide the sum by the total numbers of items in the data set.
Median – is the middle number of a data set when arranged in numerical order.
Mode – is the number or item that appears most often in a data set
Range – the difference between the greatest number and the least in the data set. Subtract the smallest number from the greatest and that is the range

16. hypothesis
After a hypothesis is tested, you analyze your results using different methods
Often it is hard to see trends, or relationships in data while collecting it.
Data should be sorted, graphed or classified in some way

17. know
The vocabulary
How to find variables in an experiment – independent and dependent, constants, and what is a control group
