What is Science?•Science is the attempt to
put the universe in some kind of order that humans can understand.
•From Latin scire (which means “to know”)
Science is constantly changing!
• Scientists verify each other’s work.
• Every once in a while, the scientists find that a theory or scenario does not always hold true…. So what then?????
Here are some famous scientists…
Albert Einstein Louis Pasteur
Germany- 1879 France- 1822
Physicist The Germ Theory
And more famous scientists…
Benjamin Banneker Rosalind FranklinUnited States- 1731 England- 1920
Farmer’s Almanac x-ray crystallography of
& wooden clock DNA
So far we know…•Science is constantly changing•Scientists can be from any race,
gender, age, culture or religion.•Scientists like to work in groups!
Step 2: Research the Problem
• Look at reliable sources• Determine what is already
known about the problem.
Step 3: Form a Hypothesis
•Hypothesis- a testable explanation of an observation
• A hypothesis is NOT just an educated guess about what you think will happen. It must be TESTABLE!!!!
Step 6: Organize & Analyze your data
• Put your data into a data table
IndependentVariable
__________(unit)
Levels
Dependent Variable _______________ (unit)
Trial 1 Trail 2 Trail 3 mean range
Step 6: Organize & Analyze your data
•Make the data table into a graph
•Graphs make it easier to see patterns in the data.
Step 6: Organize & Analyze your data
– Dependent Variable = Responding Variable = Y axis– Independent Variable = Manipulated Variable = X axis
Step 7: Draw Conclusion(s)
•Was your hypothesis correct?• If your hypothesis was not
accurate or if you think there was an error collecting data Start over and re-do experiment!
