Scientific Method
Name 2 steps that could be first in the scientific method?
What is Question, Observation, Background Research.
No, Airplane B will not fly better than airplane A, because it has shorter wings. Fix this hypothesis.
What is: Airplane B will not fly better than A because Airplane B has shorter wings.
What are the two types of variables in an experiment?
What is Independent and Dependent.
Find the independent and dependent variables in the following experiment: If you increase the number of oranges you eat, then you will feel better from all the vitamin C you're eating.
IV = number of oranges
DV= how you feel
This type of observation is measureable.
What is Quantitative Measurement.
If I put my plant in the closet then it will decrease its chance of living. What is wrong with this hypothesis?
What is... it contains "If" and "Then"
What is the responding variable or factor that may or may not change due to manipulation?
What is Dependent Variable.
Does plant location affect how fast it grows?? Identify the IV and DV.
IV = Locations of plants
DV = Rate of growth
What step in the scientific method do you observe data and look for patterns/answers?
What is Analyze Data.
This type of observation is describable/uses senses.
What is Qualitative Measurement.
If you drink more milk will you get stronger bones? State a good hypothesis for this question.
What is...Increasing the amount of milk you drink will increase the strength of your bones because bones need calcium to be strong.
The ________________ involves a series of steps that are used to investigate a natural occurrence.
What is Scientific Method.
What step of the scientific method do you predict a possible answer to a problem or a question?
What is Hypothesis.
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....
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.
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.
List all six steps of the scientific method.
What is Question, Hypothesis, Experiment, Observe and Record, Analyze Results, Share Results.
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......"An increase in running will cause an increase in heart rate because your body is working hard to supply oxygen to muscles"
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.
Thinking about the hypothesis: If soil temperatures rise, then plant growth will increase. What would you keep controlled in this experiment?
What is... using the same potting soil, making sure both plants have an equal amount of light, same location, same size pot, same type of plant etc.
