________ is something that is not understood but can be investigated through experimentation or scientific investigation. 

• hypothesis
• scientific law
• scientific problem
• scientific theory

An observation is different from an inference since:

• Inferences always lead to experiments, observations do not

• Observations do not temporarily explain something like inferences do

• You make thousands of observations daily, but less inferences

• Inferences can be proven, observations cannot be

Observations:

• Require inferencing to be made

• Do not lead to inferences

• Are made using your senses

• Only take place prior to hypothesis formation

This leads to that.

• Observations lead to an inference

• Inferences lead to an observation

Which of the following is an example of an inference:

• The fish are small and seem to look the same

• The water is shallow and very clear

• It is a sandy and bare ecosystem

• The fish are hiding from a possible predator

Which of the following is an example of an observation:

• Hurricanes seem to make rough waves

• The waves are rough today

• Hurricanes lose strength over land

• Hurricanes rotate since the Earth also rotates

Which of the following is an example of an inference:

• Birds diving into the ocean means there are small fish there

• Birds flying over the ocean typically do not flap their wings

• Oceanic birds are larger than land birds

• The fish is floating very still under the floating seaweed

Which of the following is an example of an observation:

• The ocean creates foam when there are rough waves

• The seaweed grows best with nutrients

• The seaweed floats on the ocean water

• The stronger the winds the bigger the waves are
