Activity #64-65: Breeding Critters


During block days this week students completed a couple different activities. First students read about the importance of chromosomes. They found out that every human cell except egg and sperm has a total of 46 chromosomes (23pairs). The sperm and egg only have 23 so when they combine for fertilization the offspring will have 46. Students also learned how genes are on chromosomes which determine traits. The last part of the reading was about mutations and how they can change chromosomes and genes. Next, students made critters with different traits ranging from nose size, body color, number of eyes and more. They created a creature with traits that were determined by tossing coins. Students will draw and describe their creature on Friday.

Homework: Sponge Bob Genetics due on Friday

Hint: Quiz on Friday
