3. Student Learning Map

  • Topic:09- Meiosis and Reproduction
  • Subject(s):Science
  • Days:15
  • Grade(s):9
Key Learning:

Meiosis and the process of sexual reproduction lead to genetic variation in organisms. Reproduction is characteristics of living things and is essential for the survival of species.
Unit Essential Question(s):
 
 

How do the events of meiosis affect the development of a human fetus?
   
Concept:

Meiosis

SC.912.L.16.17   SC.912.L.15.15  

The regrouping of genes in an offspringthat results in a genetic makeup that is different from that of the parents.
Concept:

Asexual and Sexual Reproduction

SC.912.L.16.17  

Differentiate between asexual and sexual reproduction. List the advantages and disadvantages of sexual reproduction and asexual reproduction. Discuss the consequences of genetic variation in relation to sexual and asexual reproduction.
Concept:

Human Reproduction and Development

SC.912.L.16.13  

Discuss the basic anatomy of the human reproductive system. Examine the basic reproductive parts of both males and females. Discuss the function of the human reproductive system.

Outline the process of human development from fertilization to birth. Be sure to discuss all the developmental milestones that occur during each trimester of pregnancy.

HOTS: Comparing/Contrasting could be used to demonstrate the ET LEQ.

Vocabulary Report

  • gamete (sex cell) -

    A haploid reproductive cell that unites with another haploid reproductive cell to form a zygote.

  • *meiosis -

    A process in cell division during which the number of chromosomes decreases to half the original number by two divisions of the nucleus, which results in the production of sex cells (gametes or spores).

  • Genetic Recombination -

    Gobbly Gook

  • fertilization -

    the union of of a male and female gamete to form a zygote

  • trimester -

    one of the three equal periods of about 12 weeks into which the human gestation period is divided
