Home Learning O You should have completed Page 33 last class, or as home learning. O REMEMBER! If you got stuck or need help I am available for tutoring after school! O Some of us were assigned Page 34 - Let’s check our class progress.
Miller-Urey experiment (1953) O Scientists recreated the inorganic atmosphere of early Earth O Simulated lightning to demonstrate how electrical current could create organic molecules from a mixture of gases. O Organic molecules created included amino acids. Why is this monomer so important to life?
REVIEW O Organic compounds contain what TWO atoms? OCarbon OHydrogen O Organic Molecules must be formed before life can exist
What was the first life like? OAnaerobic organisms…why? OSingle celled prokaryotes OAsexual Reproduction OHeterotrophs…why?
What came next? • Autotrophs…why? • Endosymbiosis O The creation of the Eukaryotic cell. O Smaller free-living bacteria were enclosed within a larger cell becoming what we know today as organelles • Multicellular organisms • Sexual Reproduction--how would this influence evolution? • HUMANS
Page 34 O Compare and Contrast the Theory of the Origin of Life with the cell theory proposed by Francisco Redi. O Recall that Francisco Redi disproved spontaneous generation in the 17 th century.
Daily Objective O Identify basic trends in hominid evolution from early ancestors six million years ago to modern humans, including brain size, jaw size, language, and manufacture of tools.
How will we get there? Last Class OFCIM: Common Molecules OPage 33: QUIZ 4 OPage 32: SRE ENRICHMENT OPage 35: Timeline Engage and Notes: Origin of Life OPage 34: Questioning Theories Today’s Class O Lab Rotations: Pg 36 O Notes: Hominid Evolution Pg 37 O Home Learning: O Flashcards
ENGAGE O I need 8 Volunteers up front O (you don’t have to do anything special just stand) Ok Now that we have our 8 volunteers, we need to decide what this “group” has in common Now we need to separate them into 2 separate groups
Explore O Just like you just demonstrated, all of life can be classified into groups. O Scientists began to wonder how humans fit into the world around them. O How have we changed? O Where did we come from? Keep an open mind as we explore one attempt to explain these questions.
Remember, this is a state standard. Is this a law? Do you have to agree with these points? Should you question these points? Will you be tested on this information?
Hominid Lab Stations: Page 36 O I am providing a handout for this activity. O You will not need your notebook, however it IS YOUR RESPONSIBILITY to staple/paste/tape it in after the lab.
Directions: Rotations We will be investigating the classification of hominids using three lab stations today. 1. Hominid Skulls O Compare different species of hominids 2. Digging for Fossils O Classify unknown fossils 3. Boom Bag O Test your vocabulary
Hominid Skull Lab It is extremely important that you handle these casts with care! They are on loan from UNF. REMEMBER you are getting an experience that most students in Duval County will never get! O Make qualitative and quantitative observations following the instructions at your lab table. Let me show you how to take cranial circumference. O You have 15 minutes to collect your data and complete your data table and graph this information.
EXPLORE: Digging for Fossils O You are going to classify images of fossils as either chimpanzee (Pan troglodytes) or human (Homo Sapien). O Compare and contrast the unknown fossils from Envelope #2 with the keys provided O You will have 15 minutes to classify your bones and create your scientific report.
Boom Bag Do you have the academic vocabulary to demonstrate your mastery of this objective? O Alternate turns to test yourselves! O Remember: O If you get the question right you earn the slip! O Get it wrong and you have to put it back O Pull a boom and ALL of your slips go back.
Transitioning to Stations O Just like our usual transitions I am going to allow you to pick your first station O HOWEVER there may not be more than 8 students per station. O When you get to your first station please find that station on your handout. O DO NOT BEGIN UNTIL I CALL TIME!
Transition ORemember the directions, if you get confused reference your handout or ASK FOR HELP!

HOMINID EVOLUTION NOTES Page 37 Applying a theory, and classifying the human species. Is this a law? Do you have to agree with these points? Should you question these points?
Taxonomic Classification O We are Domain Eukarya O Why? O We are Kingdom Animalia O Why? O We are mammals. O Why? O We are primates. O Why? LET ME TELL YOU!
Primates
Primates O animals with five flexible fingers with an opposable thumb (include monkeys, apes, and humans) O Have binocular and color vision O Evolved about 35 million years ago O Human DNA and chimp DNA is 98. 4% similar!!!
Evolutionary Origins
HOMINIDS humans and their closest fossil relatives
Skulls are evidence for human evolution
Language O A lot of people think that language is tied to brain size, or intelligence O HOWEVER, vocal abilities come from the anatomy of our vocal chords, and are primarily due to our upright stance!
A bonobo with bipedal locomotion.
So why don’t bonobos speak? ? O The structure of our spinal chord allows us to make a wide range of noises, but the development of language comes from a more complicated development of culture. O REMEMBER we are not monkeys, chimps or apes. We are our own species, and have defining characteristics!
“Lucy” • The oldest hominid (3 myo) • Discovered by Johanson in 1974 in Ethiopia • About 3. 5 ft tall / 62 lbs • Walked upright • Evidence that hominids walked upright before they evolved larger brains
The First Humans
The genus Homo evolved in Africa about 2 million years ago
We Do: On the lines of page 38 Darwin’s Explanation Make a connection! O How would Darwin explain the evolution of hominids? O Over millions of years and much change in the environment, hominids evolved to become better adapted to their specific environment.
Hominid Skull Trend Graphing Skills Page 39 O Tape this handout onto Page 39 so that you can lift it up to see the lines below. O Answer the 4 questions in COMPLETE SENTENCES using the graph. O Don’t forget to include your units of measure where necessary.
Evolution Terminology O Complete the worksheet to review your mastery of our current vocabulary. O First, attempt to define the words you know WITHOUT ASSISTANCE O Then highlight ALL of the words you have to look up. O Use your notes/textbook to define
Home Learning O Create flashcards for any new vocabulary. #YOLO O Remember to keep an open mind when discussing theories. O It is not a fact O It is not something that has to be proven O It is one attempt to answer questions raised by observation.
