3. Warm-Up 10/16 and 10/17
What 3 characteristics does a Douglas Fir share with all other plants?
How does its special leaf (needle) shape help it survive in the NW?

4. Last Time…
We discovered some of the major evolutionary events on earth, including when life evolved (more to come on that!)
This time: What does it even mean to be alive? What do we all have in common?

5. Learning Targets
I can describe the 8 characteristics that group ALL living things together.
I can use information from rock layers to describe historical environmental conditions.

6. What is Life? Biology is the study of living things
Living things are divided into six kingdoms based on genetic and physical similarities:
Plants, animals, fungi, protists, bacteria, archaebacteria
Living things (organisms) are extremely diverse, but share eight characteristics in common

7. Archaebacteria
Fungi
Plants
Bacteria
Protists
Animals

8. Characteristics of Life
#1: Organisms are made of units called cells
Organisms can be unicellular (made of one cell) or multicellular (made of many cells)

9. Characteristics of Life
#2: Reproduction
All living things reproduce themselves
Reproduction is asexual (one parent) or sexual (two parents)

10. Characteristics of Life
#3: Based on genetic code
Organisms have DNA or RNA that is a blueprint for creating them
DNA or RNA is passed on to offspring

11. Characteristics of Life
#4: Growth and Development
All organisms grow, either by enlarging their one cell or dividing their cells millions of times

12. Characteristics of Life
#5: Need for materials and energy
Organisms create and break down molecules to fuel their chemical reactions
The four molecules we use are proteins, fats, carbohydrates, and nucleic acids
This is called metabolism

13. Characteristics of Life
#6: Response to environment
Organisms detect and react to stimuli in their environment
Stimuli are internal (like your blood sugar) or external (like plants reacting to sunlight)

14. Characteristics of Life
#7: Internal balance
Organisms keep their internal environment stable through homeostasis
Ex: Body temperature
when you get too hot, you sweat to cool your skin
when you get too cold, you shiver to warm your body

15. Characteristics of Life
#8: Evolution
Populations of organisms change over time in response to their environment
Changes are only significant over long periods of time

16. Is this Yogurt alive?
Talk to a partner and be prepared to share to share out!

17. Evidence For Evolution
How do we know evolution happens?
Fossil record
a. Relative and radiometric dating
DNA comparisons
Body structures
Comparing embryos
Antibiotic resistance and Viruses

18. Gifts from the Past
Title your next notebook section “Gifts from the Past”
Copy Focus Question:
What can Fossils & Rock Layers tell us about ancient life on Earth?
(Leave 3-4 lines to answer this later).

19. Determining fossil environment
With each fossil:
Draw what it looks like in your notebook.
What does it look like that is alive today?
What type of environment did it live in?
All marine-type environment (except petrified wood possibly).

20. Things Rocks can Tell Us
What lived in that environment.
What the environment looked like.
How the environment has changed over time.
What things are more recent/ancient.

21. Types of Fossils
Trace fossils – markings left by animals (footprints, trail, burrow).
Casts – Minerals fill a space left by a decaying organism.
Petrified Fossils – Minerals penetrate, replace hard parts of organism, producing a copy.

22. Types of Fossils
Imprints – Thin object that leaves an imprint when sediment hardens.
Molds – Organism is buried then decays, leaving a gap.
Amber-Preserved / Frozen – An organism is trapped in ice or sap that hardens.

23. Things Rocks can Tell Us
What lived in that environment.
What the environment looked like.
How the environment has changed over time.
What things are more recent/ancient.

24. Rock types describe environments
Freshwater floodplain, lake or lagoon? Shale rock is present.

25. Rock types describe environments
Large amounts of Calcium & Magnesium? Maybe some specialized bacteria? Dolomite rock that only forms in salty lagoons.
Rock types describe environments

26. What was it like then?
Shallow, warm marine environments? Lots of Calcium Carbonate (like seashells)? Limestone.

27. Rock types describe environments
Sandstone – describe ALL possible environments.
Terrestrial (Land-based):
Rivers (sandbars, mouth)
Glacial outwash
Deserts
Lakes
Marine (Ocean-based):
Beach
Tidal flats
River/ocean deltas

28. Things Rocks can Tell Us
What lived in that environment.
What the environment looked like.
How the environment has changed over time.
What things are more recent/ancient.
