Process of Science

Using the experiments on

the effect of bee predators on bee feeding behavior

as a model

there is no single one way that scientists study the natural world but
There is no single one way that scientists study the natural world, but

there is a general process that most scientists use.

key elements in the process of science are
Key Elements in the Process of Science Are:
  • Observations
  • Questions
  • Hypotheses
  • Predictions
  • Tests/ Experiments
  • Communicating
most people get hypotheses and predictions confused
Most people get hypotheses and predictions confused.
  • Hypothesis: A tentative explanation for a natural phenomenon.
  • Prediction: A forecasted outcome of an event based on evidence or a hypothesis.
using our bee experiment as a model
Using Our Bee Experiment As a Model
  • Jesse observesthat bees as a group will avoid areas where there are predators.
  • So, she questions: Why do bees avoid areas with predators?
  • She hypothesizes:
  • Maybe because bees can smell when a bee dies, and avoid these areas.
  • Maybe because bees can see large predators, and avoid these areas.
  • Maybe bees can smell the odors of predators
making predictions
Making Predictions

Scientists use deductive reasoning to predict the results of new observations and experiments.

Deductive reasoning follows:

an “if ….and…. then” logic.

  • If our hypothesis is correct, and we test it, then we can expect a particular outcome.
let s use our first hypothesis
Let’s Use Our First Hypothesis
  • Jesse observesthat bees as a group will avoid areas where there are predators.
  • So, she questions: Why do bees avoid areas with predators?
  • She hypothesizes:
  • Maybe because bees can smell when a bee dies, and avoid these areas.
  • Maybe because bees can see large predators, and avoid these areas.
  • Maybe bees can smell the pheromones of the predators
making our own if and then statement
Making Our Own “If…and…then” Statement
  • If the bees avoid predators because bees can smell when a bee dies, and avoid these areas,
  • question and hypothesis
  • And we have two feeding dishes and put a smashed bee on a filter paper next to one feeding dish,
  • experiment
  • Then the bees should avoid the feeding dish with the smashed bee.

qualities of a good experiment
Qualities of a Good Experiment

It is controlled.

  • There are two parallel test groups
  • The variable of interest is changed in one group (the test group), but everything else remains the same.
  • Sample size
now you design your own experiment
Now you design your own experiment
  • Generate three hypotheses
  • Choose a hypothesis
  • Write an If….and…then statement for your hypothesis.
review the experiments
Review the experiments
  • Does the experiment match the hypothesis?
  • Does the prediction match the experiment?
