1. What problem are you solving? What are you trying to discover?
Gathering/ collecting information with your senses.
Observations that have numbers. Ex: height, mass, volume, distance, counting #’s
Observations that include descriptions. Ex: moderate rusting, gradual deforestation, dress-code violations concerning holes in jeans
Coming to a conclusion based on observation. Reading between the lines. Ex: if you see smoke you can come to the conclusion that there is a fire, or if Ms. Braget sees bad quiz grades I can come to the conclusion that a student (s) did not study.

2. Using prior knowledge to determine what may happen in the future.
Your personal feelings or beliefs. How you feel about something.
Proposing explanations to questions based on gathered evidence
Finding background information about a topic, question, or problem. Scientists use this information to help guide them during their experimentation and to help analyze collected data.
A possible answer to a scientific question. Using prior knowledge and researched information to try to determine to outcome of your experiment. If…, then..., because format.
This is what is being tested in the experiment. The 1 thing you are changing.
This is what is being affected by the change. What you are measuring.
All of the things that you are keeping the same to make the experiment valid.
An experiment where all things are controlled but the one test (independent) variable you are changing.

3. What? – measures? – SI Unit – How do you measure it
The process in which you test a hypothesis and gather data through observations and measurements by following a procedure.
You gather data by recording observations before, during, and after an experiment.
When gathering quantitative observations in science you use the metric system.
Standardized system of measurement based on the number 10
Uses prefixes Kilo- (1,000), deka- (10), -- (none), centi- (one hundreth) , milli- (one thousandth), micro- , and nano-
Standard system of measurement that allows scientists to be able to easily communicate with each other.
What? – measures? – SI Unit – How do you measure it
Length- distance – meter – ruler/tape measure
Mass – total matter – kilogram (kg) – balance
Weight – amount of gravity acting on object – Newton/ kg – spring scale
Volume – how much space something takes up – liters (L) /cm3 – graduated cylinder / LxWxH
Density – how much mass is in a given volume- kg/m3, g/mL – D=m/v
Time- how long- second (s) – clock or timer
Temperature – how much thermal energy – Kelvin(K),Celsius(C), Fahrenheit(F) -Thermometer

4. When you perform your experiment multiple times to get more accurate and reliable results
Looking at the collected data and information to understand it better.
The facts, figures, and evidence collected in the experiment
An approximation of a number based in reason, best guess
How close a measurement is to the accepted value ,4, 4.2
How close measurements are to each other. 4 -3, 3, 3.1
Picture of data to recognize trends, see errors, help make predictions, and interpret meaning.

5. Any data that does not fit with the rest, could show a possible error
20 , 23, 24, 21 , 20 , 41, 22, 21
41 does not fit with the data trends.
Is used in science to understand and interpret the quantitative data from an experiment.
Numerical average. Add all #’s in data then divide by the # of items you added
The middle number in an ordered set. Put numbers in order, find the middle value. If two numbers “share” middle, find their average.
The number that appears the most in a set of data.
The difference between the greatest and smallest value in a data set. Largest number – smallest number
Grouping together items that are alike in some way.

6. The data and observations that have been collected in an experiment.
Analyze the results of the experiment, identify important trends, determine effectiveness and importance of project
Using logical reasoning to explain results and make generalizations
Reasoning based on evidence
Reasoning based on personal feelings or beliefs. Mostly used at the beginning of an experiment.

7. An undesirable results of either taking or not taking action
A desirable result of either taking or not taking action
A statement that describes what scientists expect to happen every time under a particular set of conditions.
Ex: The Law of superposition
Will not likely change in the future
A well- tested explaination for a wide range of observations and experimental results.
Ex: Theory of plate tectonics, Theory of Evolution
Can always be disproved or altered in the future
When another scientist performs your experiment to verify/check your results.
