A prediction is a guess what might happen based on observation.
Here are some steps to think about to make a dependable prediction:
Collect data using your senses, remember you use your senses to make observations.
Search for patterns of behavior and or characteristics.
Develop statements about you think future observations will be.
Test the prediction and observe what happens.
A hypothesis is a possible explanation for a observation or problem that can further be tested by experimentation. Hypothesis' are also known as educated guesses.
Here are the steps to form a hypothesis:
When developing a hypothesis think about any observations or previous knowledge you know about the variables.
Express what you think will be the effect of changing one of the variables (Independent variable) on the other variable you expect to change (Dependent variable).
Develop your hypothesis using a statement.
A example of a hypothesis statement would be, As the (independent variable) ( describe how you would change it) , then the (dependent variable ) will (describe the effect)
