Additional Questions/Notes I can identify the time periods in which different fossil organisms existed on Earth. Pre-Cambrian Era Time Period Walk Through (handout) Paleozoic Era Q. What is the oldest Time Period? Mesozoic Era A. Pre-Cambrian Cenozoic Era Q. What Time Period are we currently living in? Date: Sept. 16 – Sept. 29 Geologic Timescale A. Cenozoic Mass Extinction Q. What is the order for the time Periods from oldest to youngest? Pages: ____ through ____ I can analyze pictorial data from the fossil record to identify any changes in organisms through time. A. Pre-Cambrian, Paleozoic, Mesozoic, Cenozoic Trilobite Index Fossil variety Q. What 3 items help us compare animals to their ancestors or to living organisms today? A. DNA, Teeth, Bone Structure. Date: Sept. 28/29 Q. These are the ancestors of a horse. What can you identify in this picture? A. a change in organisms over time I can investigate data from the fossil record showing mass Cretaceous period, Tertiary period, Paleogene period, Q. What Evidence do we have that splits the Mesozoic and Cenozoic? A. K-T boundary extinctions or abundance of life based on fossil evidence. foraminifera, extinction, fossil, sediment, morphology Q. How can you determine if a mass extinction event occurred? A. If a large number of species went extinct in a short amount of time. Date: Sept. 28- Oct. 12 Q. What is the definition of mass extinction? A. The extinction of a large number of species within a relatively short period of geological time, thought to be due to factors such as a catastrophic global event or widespread environmental change that occurs too rapidly for most species to adapt.

Additional Questions/Notes Completed “All in the Family activity” Q. What piece of evidence did we use to say that hippos and whales were the closest living relatives to each other? A. DNA Q. How can we compare these two organisms? A. Bone Structure/anatomy. I can collect data to use as evidence when writing a scientific explanation showing the relationship between whales and Mesonychids Cetaceans Perissodactyl Artiodactyl Ungulate Q. ancient mammals. What does the bone structure of these say about their past? A. they have a common ancestor. I can use evidence to develop a scientific explanation showing the relationship between whales and ancient mammals. I can analyze pictorial data to sequence developing embryos from early, middle, and late stages of development. Q. How can we compare Mesonychids with modern day whales? A. Their Primitive whale teeth. Embryo Species Vertebrate Q. What Similarities do the stage 1 embryos of vertebrates have? A. Similarities include similar eyes, tails and visible spinal columns. Q. What does the first Stage tell us about a calf, Human, fish, and a pig? A. Common Ancestors due to similarities of the embryos Q. Odd one out A. Fish/14 Q. What difference do stage 3 pigs and chickens have? Snout and beak, a chicken has wings and a pig would have 4 legs. Q. Describe a trend you observed as the embryos developed from stage to stage. A) The Embryos become more developed as you go from stage to stage.
