Scientific Method
Every scientific experiment begins with this.
Question/Problem
In an experiment testing which ball bounces highest, the different types of balls represent this variable.
Independent Variable
This type of observation uses numbers and measurements. (Qualitative or Quantitative)
Quantitative
What is the phrase to remember the metric prefixes?
King Henry Doesn't Usually Drink Chocolate Milk
Give one reason why scientists use scientific notation.
It is easier to work with very large or very small numbers.
These are the step-by-step instructions of an experiment.
Procedure
In the same ball-bouncing experiment, the height of the bounce is this variable.
Dependent Variable
Saying a liquid is "red in color" or a room is "large" are examples of this type of observation.
Qualitative observation.
To convert to a smaller unit, you move up or down the ladder?
Down
Scientific notation is most helpful when numbers are "very ____" or "very ____."
large or small
This is the term for a variable that a scientist changes on purpose in an experiment.
Independent Variable
Factors like the starting height and the amount of force that are kept the same are called this.
Controls
Which of these is quantitative: "The rock was heavy" or "The mass was 91 grams"?
The mass was 91 grams
To convert to a larger unit, you move up or down the ladder?
Up
Name 2 safety rules to follow when working in a lab.
Listening to all instructions
● Wearing closed toed shoes
● No baggy clothes
● Wear gloves
● Waft chemical smells to your nose
● Pull long hair out of the face
● Jewelry should be out of harms way.
● Wash hands often
● If chemicals get in the eye, wash thoroughly with cold water.
● Tell the teacher immediately if there is an accident.
● Tell teacher immediately of broken glass.
● No gum
● No eating
● No horseplay
This is the variable that is measured or recorded to see how it responds to changes.
Dependent Variable
True or False: An experiment should have multiple independent variables changed at the same time.
False (Only one should be changed to ensure a successful solution)
Is 0.25 cm in length qualitative or quantitative data?
Quantitative
Convert 28 meters to kilometers
0.028Km
1.7 x 10-2=
0.017
When using the scientific method, this is a possible explanation or prediction that can be tested.
Hypothesis
Name all 3 types of variables
Independent, Control, Dependent
When describing a room, saying it has a "large sq. ft." is quantitative, but saying it is "large" is this.
Qualitative
Convert 1 gram to centigrams
100 cg
1.7x104=
