Should you ever change your results to match your hypothesis?
What is NO! You can do more tests or trials to increase the accuracy of your experiment.
What step of the scientific method do you test your hypothesis?
What is Experiment.
This type of observation is measurable and gives numbers.
What is Quantitative Measurement.
A paleontologist wants to run a test on a fossil to determine how old it is. Where would he run this test?
What is in a laboratory.
What is the responding variable or factor that you measure in an experiment?
What is Dependent Variable.
What can you do to make your experiment more valid (trustworthy)?
What is do more repetitions. Collect more data and do more trials.
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.
This type of observation is describable using your five senses.
What is Qualitative.
How do scientific ideas change?
What is by new evidence and collaboration and debate.
What is the term we use to describe the manipulated variable or factor that the you change?
What is Independent Variable.
What is another type of scientific investigation that does not include variables?
What is observing and counting animals, or plants. .
In which step of the scientific method do you look for patterns in all the measurements from the experiment?
What is Analyze Data.
A description of a specific relationship under given conditions.
What is a law?
In an experiment what are the variables that are not being studied that you keep the same so that they do not influence the experimental outcome called?
What is Constant variables.
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 seven steps of the scientific method.
What is Observe, Question, Hypothesis, Plan, Experiment, Analyze Data, Conclusion.

What is a biologist, botanist, zoologist?

What is Independent- practice shooting free throws, Dependent- making baskets.
Thinking about the hypothesis: If soil temperatures rise, then plant growth will increase. What might a constant variable in this experiment be?
What is... using the same potting soil, making sure both plants have an equal amount of light etc.
