4. Quizzes back from before spring break Track your results on your quiz sheet, answer these questions on the back – Pull out your tracker from the ACP and compare it to the new tracker 1. Did your mastery increase on the latest TEKS? 2. Did mastery go down on any TEKS by more than 20%? 3. What TEKS/main topics do YOU need to focus on in tutoring (anything below 80%)

5. Use your data If you have low TEKS, come to tutoring for extra help on these YOU now know what you know, know what you dont know. Use that to know what to study. A man who knows what he knows knows what he doesnt know, then knows what to study.

7. What is EVOLUTION? Evolution is: A gradual change in organisms over a long period of time.

8. What is NATURAL SELECTION? The mechanism of evolution The process of organisms having traits that enable them to better survive in an environment.

9. Example of Natural Selection In this example of natural selection, a bird will most likely see and eat the light colored moths in the dark environment and eat the dark colored moths in the light environment. The surviving moths will live to pass their trait on to their offsprings.

10. Phylogenetic Tree A phylogenetic tree shows the relationship of organisms in a diagram format. Animals that are closely related are near each other on the diagram.

11. Phylogenic Tree of Primates Common Ancestor HumanChimpanzee GorillaOrangutan Gibbon Humans and Chimpanzees are closely related.

21. Exit Ticket 1.Scientists call the gradual change in organisms over a long period of time ____________ 2.The ability of organisms with stronger, more fit traits to survive and reproduce while weaker, unsuited organisms die is called _______. 3.A man had a termite problem in his home. The exterminator treated the termites with a chemical, killing 90% of them. The problem returned months later, and this time the chemical only killed 50% of termites. What best explains the reason for this? A.The chemical is only effective against mature termites B.The termites taught one another how to fight the chemical C.The termite digestive system changed to metabolize the chemical D.The surviving termites had a natural resistance that was inherited by offspring 4.The phylogenetic tree to the right shows evidence of: A.A common ancestor B. Natural Selection C. AdaptationD. Learned traits 5.Looking at the phylogenetic tree to the right, which organism is most closely related to V?

23. The Periodic Table You know this – so we will be brief!! Switching gears for a minute…

25. What you know about that… element

26. Atomic Structure In the nucleus - Protons – positive charge Neutrons – neutral charge Orbiting outside – Electrons – negative charge

27. Groups and Periods Groups are vertical, periods are horizontal There are 18 groups and 7 periods
