100
Descriptions or characteristics collected during an experiment. (qualitative or quantitative)
What is qualitative data.
100
A proposed explanation that can be tested.
What is a hypothesis.
100
This variable changes due to the manipulated variable and is measured.
What is a dependent variable?
100
A final explanation of the results.
What is the conclusion?
100
We ask these from our observations of the natural world.
What are questions?
200
Data that involves numbers, measurements and amounts. (qualitative or quantitative)
What is quantitative data?
200
Hypothesis or not? If I work hard, then I will do well.
NOT: It should not include the word I, it is not specific, and does not explain why.
200
These variables are kept the SAME to ensure a fair test.
What is a controlled variable?
200
A test used to support or eliminate a hypothesis.
What is an experiment?
200
Identify the controlled variables: You water three sunflower plants with salt water. Each plant receives a different concentration of salt solutions. A fourth plant receives pure water. After a two week period, the height is measured.
Controls: All the plants are sunflowers and they are each watered for 2 weeks.
300
What do these represent: Plane 1 travels 1.5 meters Plane 2 travels 1.3 meters Plane 3 travels 1.75 meters (qualitative or quantitative)
What is quantitative data?
300
A ____________ states that IF an action is taken, THEN something else will change as a result and that I know this BECAUSE of my previous knowledge.
What is a hypothesis.
300
The ONE variable that is purposefully changed.
What is an independent variable?
300
The _______________ process is question based and leads to further investigations.
What is the inquiry process?
300
Identify the independent variable: You want to test which size of soccer ball is easiest to juggle with your feet. You test a size 3, size 4, and size 5 ball. You count the seconds the ball stays in the air for each of the trials.
What is the size of the soccer balls?
400
Give an example of Quantitative Data.
Numbers: Example 1, 2, 3
400
True/ False: Hypothesis must be testable.
True

Identify the independent variable: One tank of gold fish is fed the normal amount of food once a day. A second tank is fed twice a day. A third tank is fed four times a day during a six week study. The fish’s weight is recoded daily.
What is the number of times the fish are fed?
400
Using your senses to provide factual evidence.
What are observations?
400
Identify the dependent variable: You want to test which size of soccer ball is easiest to juggle with your feet. You test a size 3, size 4, and size 5 ball. You count the seconds the ball stays in the air for each of the trials. You allow yourself to use both of your feet, knees, and head to juggle the ball.
What is the number of seconds the ball stays in the air?
500
Tigers are orange with black stripes and they have white underbellies. What type of data is this? (Qualitative or Quantitative)
What is qualitative data.
500
Is a hypothesis just an educated GUESS?
No, it is based on prior knowledge.
500
Identify the dependent variable: You water three sunflower plants with salt water. Each plant receives a different concentration of salt solutions. A fourth plant receives pure water. After a two week period, the height is measured.
What is the height measured?
500
Scientists sharing their findings so that others might verify their work and to share knowledge.
What is presenting or communicating the results?
500
Identify the controlled variables: One tank of gold fish is fed the normal amount of food once a day. A second tank is fed twice a day. A third tank is fed four times a day during a six week study. The fish’s weight is recoded daily.
What are the type of fish food, and the length of the study?
