Scientific Method
What is the first step in the scientific method?
What is the Problem/Question.
What do you use to form an observation?
What is your senses?
What are the two types of variables stated in a hypothesis?
What is Independent and Dependent.
What should you go over before starting any experiment?
What is the Lab Safety.
What senses are you using when observing a plant specimen?
What is sight, smell, and touch.
If I put my plant in the closet, then it will decrease it's chance of living. What is wrong with this hypothesis?
What is... it is missing the explanation/ the "because" statement
What is the responding variable or factor that may or may not change due to what you change in the experiment?
What is Dependent Variable.
What kind of graph have you used to put your information into and draw conclusions about your experiment?
What is a Bar Graph.
What senses are you using when observing a chemical reaction, like the bubbling that occurs when Alka-Seltzer is put into water?
What is sight and hearing.
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 vitamins needed for bone growth.
What is the term we use to describe the manipulated variable or factor that you intentionally change?
What is Independent Variable.
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.
In which step of the scientific method do you present your experiment, observations and share the results to others?
What is the conclusion?
Blue, rough, metal are all examples of what type of observation (Qualitative and Quantitative)
What is Qualitative Measurement.
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 cigarettes are a known carcinogen.
List the independent and dependent variables in the following hypothesis. If soil temperatures rise, then plant growth will increase.
What is...Independent-soil temperatures, Dependent-plant growth.
After you complete your lab safety, what should you read over before starting your experiment?
List all six steps of the scientific method.
What is Question/Problem, Hypothesis, Experiment, Observe/Record, Analyze Results, Conclusion.
14*C, 140 cm heigh, 50g, 5 skittle colors are examples of what kind of observation? (Qualitative and Quantitative)
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 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...............

What is Independent- practice shooting free throws, Dependent- making baskets.
