Unit: Evolution
Standards Addressed
During Unit
Overview
Students will deepen their understanding of the scientific theory of evolution as the
fundamental concept underlying all of biology. They will investigate the scientific
evidence for the theory of evolution and understand that organisms are classified based
on their evolutionary history. Students will understand natural selection is a primary
mechanism leading to evolutionary change.

Prior Learning Experiences: In the grade prior students should have been able to …


Discuss the role of theories in science and distinguish theories from laws
Recognize that fossil evidence is consistent with the scientific theory of evolution that living things evolved from earlier species.
Unpacking the Standards: What do we want students to Know, Understand and Do (KUD)
The purpose of creating a Know, Understand, and Do Map (KUD) is to further the unwrapping of a standard to assist PLCs in answering question #1, “What do we expect all students to learn?” It is
important for PLCs to study the standards in the unit to ensure that all members have a mutual understanding of what student learning will look and sound like when the standards are achieved.
Additionally, collectively unwrapping the standard will help with the creation of the uni-dimensional scale (for use with students). When creating a KUD, it is important to consider the standard under
study within a K-12 progression and identify the prerequisite skills that are essential for mastery.
Unit H: Evolution
Essential Question: What evidence supports how the environment plays a role in the changing of organisms over time?
Standards:
SC.912.L.15.1 Explain how the scientific theory of evolution is supported by the fossil record, comparative anatomy, comparative embryology, biogeography, molecular biology,
and observed evolutionary change.
SC.912.L.15.8 Describe the scientific explanations of the origin of life on Earth.
SC.912.L.15.10 Identify basic trends in hominid evolution from early ancestors six million years ago to modern humans, including brain size, jaw size, language, and manufacture
of tools.
SC.912.L.15.13 Describe the conditions required for natural selection, including: overproduction of offspring, inherited variation, and the struggle to survive, which result in
differential reproductive success.
SC.912.L.15.14 Discuss mechanisms of evolutionary change other than natural selection such as genetic drift and gene flow.
Understand
“Essential understandings,” or generalizations, represent ideas that are transferable to other contexts.
The scientific theory of evolution explains how organisms change over time.
External factors, like the environment, affect change in organisms.
The classification of organisms is a dynamic process that changes as new evolutionary evidence is discovered.

Culminating Performance Task:
As a marine researcher, you have been asked by a local aquarium to develop a poster presentation on specific adaptations of a marine organism
from the Tampa Bay marine ecosystem. Your research presentation must include a discussion about: the adaptations the organism has to its
environment, how those adaptations may have been selected for through any of the mechanisms of evolution, what benefit those adaptations
provide to the organism, and what ancestors the organism may have had based on evidence. You must include at least 3 formal resources on
your poster.
