Major Unit Assignment
A. Students will demonstrate their understanding of that every organism requires a set of
instructions that specifies the traits. Hereditary information in the form of DNA contains
genes located in the chromosomes of each cell.
B. Reproduction is characteristic of living things and is essential for the survival of species
C. Genetic information is passed from generation to generation by DNA; DNA controls the
traits of an organism.
D. Changes in the DNA of an organism can cause changes in traits, and manipulation of
DNA in organisms has led to genetically modified organisms.
Assignment:
1. Identify a living organism.
2. Describe the environment the organism inhabits.
3. Conduct background research on the organism,1-2 pages with illustrations, create a
bibliography minimum of 5 sources.
4. Teacher should fill a hat with environmental disasters ( weather changes, water
evaporation extremes, ice caps melt, heat increases)
5. Essential Question: How quickly can the organism the student chose adapt to the new
environment? Explain in detail why?
