Observations/Inferences
Something you detect with your senses—sight, touch, sound, smell, taste
What is an observation?
What is a possible answer to a problem or a question?
What is Hypothesis.
What are the two types of variables stated in a hypothesis?
What is Independent and Dependent.
This group does NOT receive the independent variable
What is Control group
What I think based on my observations
What is an Inference
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"
What is the variable that is measured/has data collected on it?
What is Dependent Variable.
This group(s) received the Independent Variable
What is the Experimental Group(s)
"The egg spins fast" is an example of...
What is an 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 calcium helps your bones. (Or any other appropriate hypothesis)
What is the term we use to describe the manipulated variable or factor that the experimenter intentionally changes?
What is Independent Variable.
I want to determine if what I drink before practice affects how well I shoot baskets. I decide to try water, gatoraide, an energy drink and coffee. What is my control group?
What is....Water OR No drink
"Movement inside the egg means that it is raw because the yolk is moving around" is an example of...
What is an inference?
I wonder if vaping more increases my likelihood of getting lung cancer? State a good hypothesis for this question.
What is...If you increase the amount you vape, then you will increase your chance of getting lung cancer because of the chemical present in the vape. (or any other appropriate hypothesis)
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 Control.
If soil temperatures rise, then plant growth will increase. I put one plant in a room at room temperature and then put a plant in a room at 30 and 35 degrees Celsius. Which plant(s) are the experimental group plants?
What is...a plant in a room at 30 and 35 degrees Celsius
Observe your teacher. Make an inference about her based on what she is wearing.
What is...Answer includes an observation and an inference.
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 a 1 minute and I will check their heartbeat. Then they will run for 2 minutes and I will check their heart rate. I will do this up to 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 my body needs more oxygen.
Find the independent and dependent variables 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 Independent- practice shooting free throws, Dependent- making baskets.
If soil temperatures rise, then plant growth will increase. I put one plant in a room at room temperature and then put a plant in a room at 30 and 35 degrees Celsius. Which plant(s) are the control group plants?
What is...Room Temperature Plant
