SUBJECT: Science
GRADE LEVEL: 7th
GRADING PERIOD: 2nd 9 weeks
Module(s): A – Cells and Heredity
Time Frame: 4 weeks
Unit: Cells and Heredity (Evolution and
Genetics)
Essential Standard: 7.L.2: Understand the relationship of the mechanisms of cellular reproduction, patterns of inheritance and external factors to
potential variation among offspring.
Lesson: Sexual/Asexual
Reproduction
(Time Frame: 2 Weeks)
Clarifying Objective:
7.L.2.1:
Explain why offspring
that result from sexual
reproduction
(fertilization and meiosis)
have greater variation
than offspring that result
from asexual
reproduction (budding
and mitosis).

Literacy Standards Used in this Unit:
CCSS.ELA-Literacy.RST.6-8.3 Follow precisely a multistep procedure when carrying out experiments, taking measurements, or performing technical tasks.
CCSS.ELA-Literacy.RST.6-8.4 Determine the meaning of symbols, key terms, and other domain-specific words and phrases as they are used in a specific
scientific or technical context relevant to grades 6–8 texts and topics.
CCSS.ELA-Literacy.RST.6-8.7 Integrate quantitative or technical information expressed in words in a text with a version of that information expressed visually
(e.g., in a flowchart, diagram, model, graph, or table).
CCSS.ELA-Literacy.RST.6-8.9 Compare and contrast the information gained from experiments, simulations, video, or multimedia sources with that gained from
reading a text on the same topic.
