Steps of the Method
This is the first step of the scientific method and decides what you are going to investigate.
This variable is what the experimenter is changing or manipulating.
What is the independent variable?
This is the definition of a constant or controlled variable.
This is the definition of a hypothesis.
What is a prediction or guess of the outcome of an experiment supported by prior knowledge or research?
This is the definition of an observation.
What is something you notice with your five senses?
This step is another word for forming a well-researched prediction.
What is a hypothesis?
This variable is what the experimenter is measuring, or it is the outcome of the experiment.
What is the dependent variable?
This is how many constants you should have to make an experiment more accurate.
What is many or multiple?
This is the correct format for writing a hypothesis.
What is If/then format?
What is an observation that uses numbers and labels?
This is the term for the step-by-step process used to conduct an experiment.
What are the Scientific Method?
This is something that is purposely kept the same for each trial of an experiment.
What is a constant (or controlled variable)?
Give an example of a constant in our Candy Colors experiment.
What is the types of candy, the size of the packages, etc.?
This is the variable that comes after the "If" part of a hypothesis.
What is the independent variable?
This is a description of a qualitative observation.
What is an observation of qualities or characteristics of something?
This is the term for elements of an experiment that can change.
What are Variables?
This is how many independent variables you should have in an experiment.
What is only ONE?
Come up with a constant for this experiment: Does listening to classical music effect students performance on quizzes?
Possible answers: the piece of music, how long they listen, the questions on the quiz, the room they take the quiz in, etc.
Decide if the following prediction is either a good or bad hypothesis and give a reason why: "Math grades will improve if breakfast is eaten every morning."
It is a bad hypothesis because it is not in If/then format, and the IV and DV are not in the right order.
Identify if this variable is qualitative or quantitative:
"She had seventeen potted spider plants."
What is quantitative because it contains numbers.
Name at least one way you could analyze data from an experiment.
What is make a chart, make a graph, use math, make a diagram, etc.?
Identify the Independent and Dependent variables in the following experiment: If I fold paper airplanes in three different patterns, then which one will be able to stay in the air the longest?
Independent: folding pattern of the airplane
Dependent: how long it stays in the air
Come up with at least two constants for this experiment: Which fertilizer brand will make my sunflowers grow the tallest?
Possible answers: amount of water given, amount of fertilizer used, sunlight, soil, location of the plants, type of sunflower, time they are grown, etc.
Turn the scientific question into a hypothesis: "Does the amount of sunlight rosebushes receive effect how many flowers they grow?"
Example Hypothesis:
"If rosebushes are given more sunlight, then they will grow more flowers."
Name at least one quantitative observation and one qualitative observation about the classroom and tell me which is which.
Answers will vary, but the quantitative should contain numbers and the qualitative should be a characteristic.
