OCEAN 320 Lecture Notes - Lecture 1: Animal Testing, Large Blue
Unit 1A: Science & Systems
Observations & Inferences Video
• Observations:
• Image 1
o Small pink footprints move diagonally (rightward) from top to bottom, same
space between each set of prints
o Large blue footsteps move diagonally (rightward) from bottom to top, though the
footsteps at the end of the trail are further apart than those at the beginning
• Image 2
o Small pink footprints start close together and then get wider when chaos seems to
occur; all the footprints move in different directions within one clump
o Big blue footprints stay widely apart and also occur in chaotic patterns on top of
the pink prints
• Image 3
o Big blue footprints trail diagonally (rightward) down the image; no pink prints
visible
• Inferences:
• The two animals’ paths intersected
• The owner of the blue footprints lunged or pounced at the owner of the pink footprints at
the edge of the first image
• There is chaos as the blue and pink animals struggle
• The blue footprints walk away alone because it has eaten the pink animal
• Study Question:
Which of the following would be considered an inference?
a. measurement of the distance between dinosaur footprints
b. interpretation of the pattern of formation of dinosaur footprints
c. description of a pattern of dinosaur footprints
Correct Answer: B
An inference is a conclusion made by logical reasoning and creative thinking. It is not a
measurement (which would be simply data) or a description (which is made up of
observations)
