Science 10 ) Investigate how variations in characteristics among individuals of the
same species may provide advantages in surviving, finding mates, and reproducing
(e.g., plants having larger thorns being less likely to be eaten by predators,
animals having better camouflage coloration being more likely to survive and
bear offspring).

Reproducing Knowledge:
Students know:
Patterns of variation of a given characteristic among individuals in a species (e.g., longer or shorter thorns on individual plants, dark or light coloration of animals).
Potential benefits of a given variation of the characteristic (e.g. the light coloration of some moths makes them difficult to see on the bark of a tree).
Certain variations in characteristics makes it harder or easier for an animal to survive, find mates, and reproduce (e.g., longer thorns prevent predators more effectively and increase the likelihood of survival; light coloration of some moths provides camouflage in certain environments, making it more likely that they will live long enough to be able to mate and reproduce). Skills:
Students are able to:
Collaboratively investigate the variations in characteristics among individuals of the same species.
Describe evidence needed to explain the cause-and-effect relationship between a specific variation in a characteristic and its effect on the individual to survive, find mates, and reproduce.
Use reasoning to connect the evidence to support the explanation Understanding:
Students understand that:
Cause and effect relationships exist between a specific variation in a characteristic (e.g., longer thorns, coloration of moths) and its effect on the ability of the individual organism to survive and reproduce (e.g., plants with longer thorns are less likely to be eaten, darker moths are less likely to be seen and eaten on dark trees).
