Science Curriculum
Grade 9
ENDURING UNDERSTANDING:
(Is worth remembering for a lifetime and has lasting value for the student)
 Cycles
 Patterns
TOPIC/S:
Cycles
 Cell cycle
 Mitosis
 Cancer
Patterns
Meiosis
 DNA
o Structure
o Function
o Replication
 RNA
o Structure
o Function
o Protein Synthesis
 Mutations
 Gene Expression
 Punnett Squares
o Monohybrid
o Dihybrid
 Non-Mendelian Genetics &
Pedigrees
o Multiple Alleles
o Sex-linked
o Polygenic
o Incomplete
Dominance
 Probabilities
 Chromosomal Analysis
 All organisms are able to grow and develop due to the
inherited genes which were passed from parent to
offspring.
 DNA is the genetic code which specifies the traits of a
living organism.
ESSENTIAL QUESTIONS:
GUIDING QUESTIONS:
(Universal questions worth contemplation and exploration by the student)
(Fundamental queries that guide the search for student
understanding)
1. The last time you got hurt, how did your body repair
itself?
2. What sorts of patterns in your clothing define who you
are? What biological patterns define who you are?
1. What are the structures and functions of
DNA and RNA?
2. How does DNA carry genetic information
which specifies the traits of all living
organisms?
3. How is DNA replication related to the
process of mitosis?
4. What are the stages of the cell cycle and
what events occur during each stage?
5. What would a disruption in the cell cycle
cause?
6. What is the purpose and process of protein
synthesis?
7. How can genetic combinations be predicted
using the principles of Mendelian and NonMendelian genetics?
8. How do the events of meiosis ensure genetic
variation before sexual reproduction?
9. What techniques are used to study the
genomes of organisms?
10. How do mutations in DNA affect traits in
organisms and the diversity of a population?
11. How has genetics affected agriculture,
medicine, and society?
