Think Like A Scientist!

Scientific Thinking

How do we solve a difficult question?

Take 3 minutes to rearrange this engineering method according to what you think is correct.

Communicate

Brainstorm

Test the prototype

Research

Define the problem

Develop a prototype

What method does this resemble?...

                  

3 misinterpreted words in bio.....

• Hypothesis:  hypothesis will give a plausible explanation that will be tested. It can also explain future phenomenon that will need to be tested. Ex: If fenders are placed on a bicycle, then the user will stay dry when going through puddles.

• Theory: After hypotheses have been tested many times, with accurate results, they become theories. Ex: Cell Theory

• Law: A law has been widely accepted. This means that it is assumed to be a true and will predict the outcome of certain conditions or experiments.

Now lets apply this to Biology

1. A scientist is testing the effects of medication on the blood pressure of patients. 
2. A scientist wants to find out how cellular respiration is affected by temperature. 
3. A scientist is measuring the effect of precipitation on seed germination.
