Today in class, students began by playing a short simulation on natural selection and evolution (Natural Selection Simulation (Who wants to live a Million years?) ). The students found that it was not easy to survive, and more organisms go extinct than survive. The reason why is because natural selection cuts down our diversity by allowing only the advantageous traits to remain in a population. But if there is no diversity, a species can all die from the same change in the environment. For example, if everyone has short fur and it becomes colder, then everyone may die. So, diversity leads to the survival of a species; more diverse characteristics are added to the population through mutation. After finishing up the game, students worked on the Anatomical Evidence for Evolution packet. Students will have some time tomorrow in class, but it will be graded at the end of class for credit.
Integrated science students worked on their Mixture separation lab today and tried to separate the 4 substances in their mixtures. Students will have more time to finish tomorrow.
HOMEWORK: Science 8= PLay either the Natural selection simulation Rabbits and wolves (won’t work for chromebooks), Natural Selection Simulation (with blue grabbers and flies), or Blue and Green beetle Natural Selection game; Finish the Anatomical Evidence for Evolution packet.
