I can identify the time periods in which different fossil organisms existed on Earth.
Date:
Sept. 16 – Sept. 29
Pages:
____ through ____ / Pre-Cambrian Era
Paleozoic Era
Mesozoic Era
Cenozoic Era
Geologic Timescale
Mass Extinction / Time Period Walk Through (handout)
Mesozoic- age of dinosaurs, ended when asteroid/meteor hit the planet, rocky mountains formed, etc.
Cenozoic- age of mammals
Paleozoic- first large “explosion” of life, increased diversity
Pre-Cambrian- beginning of Earth
Q. What is the oldest Time Period?
A. Pre-Cambrian
Q. What Time Period are we currently living in?
A. Cenozoic
Q. What is the order for the time Periods from oldest to youngest?
A. Pre-Cambrian, Paleozoic, Mesozoic, Cenozoic
I can analyze pictorial data from the fossil record to identify any changes in organisms through time.
Date:
Sept. 28/29 / Trilobite
Index Fossil
variety / Animals have become increasingly complex and diverse throughout Earth’s history.
Pre-Cambrian- mostly single celled organisms and simple multi celled organisms (jellyfish)
Other eras: started off with little diversity and simple organisms and became increasingly complex and diverse including large number of species and the most complex organisms.
Q. What 3 items help us compare animals to their ancestors or to living organisms today?
A. DNA, Teeth, Bone Structure.
Q. These are the ancestors of a horse. What can you identify in this picture?
A. I can identify a change in organisms over time
I can investigate data from the fossil record showing mass extinctions or abundance of life based on fossil evidence.
Date:
Sept. 28- Oct. 12 / Cretaceous period, Tertiary period, Paleogene period, foraminifera, extinction, fossil, sediment, morphology / Q. What Evidence do we have that splits the Mesozoic and Cenozoic?
A. K-T boundary
Q. What was the largest mass extinction in Earth’s history?
Permian- Triassic
. What is the definition of mass extinction?
A. Theextinctionof 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.

Evolution / Completed “All in the Family activity”
Other than comparing anatomy we can compare DNA, fossils from ancient organisms.
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.
I can collect data to use as evidence when writing a scientific explanation showing the relationship between whales and ancient mammals. / Mesonychids
Cetaceans
Perissodactyl
Artiodactyl
Ungulate / Q. What does these organisms bone structure say about these animals?
A. they all have a common ancestor.
I can use evidence to develop a scientific explanation showing the relationship between whales and ancient mammals. / Q. How can we compare Mesonychids with modern day whales?
A. Their Primitive whale teeth.
I can analyze pictorial data to sequence developing embryos from early, middle, and late stages of development. / Embryo
Species
Vertebrate / What Similarities do the stage 1 embryos have?
- Similarities include similar eyes, tails and visible spinal cords.
A. Common Ancestors
Q. Odd one out
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.
