Students will know ….
TERMS:
Natural Selection, Extinct, Selective pressure, selective breeding, pedigree, species

It’s important to understand that…
1. Environmental factors put selective pressure on a population.
2. Natural selection is the process in which individuals best adapted to their environment tend to pass their traits on to subsequent generations.
3. Members of a species are all the same kind of organism and different from other organisms. They can breed with each other to produce offspring.

Students will be able to…
1. Use simulations to demonstrate how selective pressure can change the make up of a population.
2. They will be able to explain how selective pressures can change the genetic make up within a population over time.

LESSON #1

EQ: What is selective pressure?


You analyze the results of two generations of offspring to determine how the selective pressure imposed by predation affects the genetic composition of the population.

QuickWrite: What are some situations that would require a population of organisms to adapt to a new environment?



(Lab book page 73)
  • Record the information generated from the data table below on to the tables on page 73 of lab book.
  • Choose the prairie scenario first and complete the table for P, F1, F2, and F6
  • Choose the forest scenario second and complete the table for P, F1, F2, and F6
Show me when you are finished with page 73 and be able to explain it to me.

Try to get 100% trait frequency by F4 through selective breeding:
  • All Long Legs
  • All Short legs
  • All Red Eyes
  • All Grey Eyes
  • All Striped
  • All Solid
  • All Spotted
  • All Bushy Tail
  • All Bare Tail

CHALLENGE:
  • All LONG LEGS, SPOTTED, BUSHY TAIL and RED EYES by the 4th generation!
