TASK: 

In your blogs, write a definition and give and example for each one of these: a fact
a theory
a hypothesis
a belief
Watch again the TED video and summarise the main points.

Natural Sciences can be defined as an area of knowing that makes claim about the natural world, and attempts to find laws by which the world works.These laws are defined often,as results of experiments or tests, and usually claim to be true at all times, under the same conditions. 

However, many questions are raised when it comes to Natural Sciences. 

• How certain is knowledge gained by these methods?
• How useful is scientific law for predicting the future?

Key Terms (Definitions and Examples) 

FACT

Definition: a scientific fact is an objective and verifiable observation. A proven statement backed up by science and mathematics,in addition it  cannot be questioned 

Example: Avogadro's Law, Thermodynamics

THEORY 

Definition: A scientific theory is a assumption or an idea based on evidence and fact however has not been confirmed through science or math, thus making it an assumption, and can be questioned and challenged

Example: Evolution 

HYPOTHESIS 

Definition: Similar to theory, a hypothesis is a "educated guess or prediction" made before having any lab reports run, however the prediction is made with limited information which is why it can be supported or not supported. 

Example: Peanuts do not cause acne because there is no correlation between consumption of nuts  and acne. 

BELEIF 

Definition: Something believed by people and can sometimes have a relation within religious perspective and cultural ones too. Furthermore, scientific beliefs is based on previous factual informations. 

Example: The earth is flat 

Notes

• Humans have no control on what we learn 
• Question everything (How do we know?) 
• Looking at previous facts can help us progress in the field of science 
• Science interacts with the world 
• How did the discovers come to understand 
• The field of science is open 
• There is a difference between Facts and Theories and it is important to be able to decipher what it is
