Grade 8 Science Curriculum
Unit of Study: LIFE |
Suggested Time: 8 Weeks
|
Content Standard 8.2 Reproduction is a characteristic of living systems and it is essential for the continuation of every species.
- Heredity is the passage of genetic information from one generation to another.
- Some of the characteristics of an organism are inherited and some result from interactions with the environment.
|
Essential Question: What processes are responsible for life’s unity and diversity? |
Focus Question #1 How do cells divide?
|
Expected performances (C25) The student will be able to:
a. model the process of mitosis.
b. model the process of meiosis.
c. explain the similarities and differences in cell division in somatic and germ cells.
Required Activities:
- Mitosis modeling activity. (Ex: “Modeling Mitosis” Activity) Refer to Prentice-Hall “Cells and Heredity” Lab Zone CD-ROM (CINQ. 5, 8, 9)
- Meiosis modeling activity. (Ex: “Modeling Meiosis” ) Refer to Prentice-Hall “Cells and Heredity” Lab Zone CD-ROM (CINQ. 5, 8, 9)
Optional Activities:
none
Assessments:
(State-provided performance assessment will be imbedded in this unit)
Assess performance expectations
C25a and inquiry skills expectations. (Ex: “Compare and Contrast Mitosis and Meiosis”) Refer to
Project CRISS Manual, p. 77 (CINQ. 7)
Focus Question #2 How do humans reproduce?
|
Expected performances (C26) The student will be able to:
a. describe the structure and function of the male and female human reproduction systems, including the process of egg and sperm production.
Required Activities:
- Graphical comparison of male and female human reproductive systems. (Ex: “What’s the Big Difference” Discover Activity) Refer to Prentice-Hall “Human Biology and Health” Lab Zone CD-ROM (CINQ. 2, 8, 10)
- Body proportion development lab. (Ex: “Growing Up” Skills Lab) Refer to Prentice-Hall “Human Biology and Health – All in One Resource Book”, pgs. 454-455 (CINQ. 6, 9)
Optional Activities:
none
Assessments:
Assess performance expectations C26a and inquiry skills expectations. (Ex: “The Time of Your Life” Performance Assessment) Refer to Prentice-Hall “Human Biology and Health – All In One Resource Book”, pgs. 465-466 (CINQ. 7)
Assess performance expectation C26a. (Ex: “The Endocrine System and Reproduction” Chapter Test (modified))Refer to Prentice-Hall “Human Biology and Health – All In One Resource Book”, pgs. 467-470.
Focus Question # 3 How are traits inherited from humans to their offspring?
|
Expected performances (C27) The student will be able to:
a. describe how genetic information is organized in genes on chromosomes, and explain sex determination in humans.
Required Activities:
- Allele sorting activity. (Ex: “Chromosomes and Inheritance” Laboratory Investigation) Refer to Prentice-Hall “Cells and Heredity” – All In One Resource Book, pgs. 209-213 (CINQ. 5, 1, 4, 7, 8, 9)
- Genotype vs. phenotype activity. (Ex: “All In the Family” Chapter Project Performance Task) Refer to Prentice-Hall “Cells and Heredity” – All In One Resource Book, pgs. 166-172 (CINQ. 3, 4, 7, 8, 9)
- Dominant vs. recessive gene lab activity. (Ex: “Take a Class Survey” Skills Lab) Refer to Prentice-Hall “Cells and Heredity” – All In One Resource Book, pgs. 180-182 (CINQ. 1, 6, 7)
Optional Activities:
- Genetic probability lab activity. (Ex: “Make the Right Call” Skills Lab) Refer to Prentice-Hall “Cells and Heredity” – All In One Resource Book, pgs. 190-192 (CINQ. 5, 8)
Assessment:
Assess performance expectations C27a and inquiry skills expectations. (Ex: “Dominant or Recessive” Performance Assessment) Refer to Prentice-Hall “Cells and Heredity” – All In One Resource Book, pgs. 215-216 (CINQ. 8)
Assess performance expectation C27a. (Ex: “Genetics: The Science of Heredity” Chapter Test)Refer to Prentice-Hall “Cells and Heredity” – All In One Resource Book, pgs. 217-220
