Experiment
The number of variables one should change when designing a controlled experiment.
What is one?
What are the two types of observation?
The two variables that you should include in your well-written hypothesis.
What are independent and dependent variables?
What are the two types of variables stated in a hypothesis?
What is Independent and Dependent.
Any set of steps you take to answer a scientific question by collecting data.
What is an investigation?
Two variables that you should include in an experimental question.
Independent and dependent variables.
This type of observation is measureable.
What is Quantitative observation?
Putting my plant in the closet will decrease it's chance of living. What is wrong with this hypothesis?
What is... it is missing "If" and "then" and "because".
The variable that you collect for your data.
What is Dependent Variable.
A step in data analysis that visually compares averages for each change you made in your independent variable.
What is make an X-Y scatter graph?
What you collect while doing your trials in an experiment.
This type of observation is a description.
What is a Qualitative observation?
If you drink more milk will you get stronger bones? State a good hypothesis for this question.
What is...If you increase the amount of milk you drink, then you will increase the strength of your bones, because milk contains calcium that bones need for propper growth.
The variable that the scientist changes to test its effect on an outcome.
What is Independent Variable.
When both your IV and your DV are quantitative, you make this kind of graph.
What is an X-Y scatter plot?
The first step in analyzing the quantitative data you've collected.
What is compute an average.
Blue, rough, and metal are all examples of what type of observation?
What is a Qualitative observation?
I wonder if you smoke more cigarettes, will you have a better chance of getting lung cancer? State a good hypothesis for this question.
What is...If you increase the number of cigarettes you smoke, then you will increase your chance of getting lung cancer because cigarette smoke contains cancer-causing chemicals.
In an experiment what are the variables that are not being studied that are held constant so that they do not influence the experimental outcome called?
What is a controlled variable?
The dependent variable in the following hypothesis: If soil temperatures rise, then plant growth will increase because adding a little heat causes reactions to happen more quickly.
What is plant growth?
The paragraph you write to communicate what you think the answer is to your scientific question, and the evidence that supports it.
What is a scientific arguement.
4 cm long, 192 seconds, and 24 students are all examples of what type of observation?
What is Quantitative observation.
Read the following experiment and state a good hypothesis. I am doing a test to see if there is a connection between how long you run and how fast your heart beats. I will be performing an experiment where a person will run for 1 minute and I will check their heart rate. Then they will run for 2 minutes and I will check their heart rate. I will do this upto 6 minutes and see if there is a connection. What do you think my hypothesis should be?
What is...If I increase the amount of time I run, then my heartbeat will increase because muscles that work harder need more blood to deliver oxygen.
Find the independent variable in the following experiment: If you increase the number of times you practice shooting free-throws, then you will increase your chances of making a basket every time.
What is the number of times you practice shooting free throws.
Thinking about the hypothesis: If soil temperatures rise, then plant growth will increase. What might be a good controlled variable in this experiment?
Lots of ways to answer this - Mrs. P is the ultimate judge.
