Predators, Threats: In this section you will write about the challenges and stresses on the animal – does it have a natural predator? Can it only survive in certain temperatures or conditions?
Habitat/Range:
Habitat – does it live in the grass, in a river, up a tree?
Range – Where on Earth is it located – only in Australia, worldwide, deserts, etc.
Physical Anatomical Characteristics (label on poster): What does it look like?
Adaptations – Long nose of anteater, long neck of giraffe, etc

Behavior/Diet:
What does it eat? Does it hunt at night (nocturnal)? Does it do something no other animal does?

I. Absolute and relative dating
- Absolute dating is a method of estimating the age of an object in years – it uses the known half-life of radioactive materials
- The half-life of an atom is how long it takes half of the atoms to decay
- Relative dating is a method of sequencing events in the order they happened – it determines the age of an object relative to other objects or events in a sequence
II. Geologic Time Scale – a model of the history of life on Earth
- Highlights of life on Earth
- Earth was formed 4.6 billion years ago, starting the Precambrian era
- 3.4 billion years ago, life appeared on Earth (bacteria).
- Modern humans appeared 40,000 years ago.
Precambrian Era – Over 540 million years ago
- No oxygen, rich in other gases – carbon monoxide, carbon dioxide, hydrogen, and nitrogen.
- A lot of chaos – Meteorites crashed into the Earth’s surface; violent thunderstorms and volcanic eruptions were constant; intense Ultraviolet radiation from the sun
- Life started from the chemicals that already existed in the environment.
- As time passed, these chemicals became more and more complex
- Earth was believed to have began 4.6 billion years ago
Paleozioc Era – 540 million – 248 million years ago
Types of Organisms:
- Plants, fungi, air-breathing animals
- All major plants except flowering plants
- Crawling insects and some reptiles
- The Paleozoic era ended with a mass extinction, killing over 90% of marine animals.
Mesozoic Era – 240 million – 65 million years ago
- A giant meteorite (space rock) hit the Earth that generated dust clouds.
- Dust and smoke blocked sunlight.
- Without sunlight, the plants died.
- Without plants, plant-eating animals died.
- Without plant-eating animals, animal-eating animals died.
Types of Organisms
- Dinosaurs
- Giant Marine lizards
- First birds
- Flowering plants
Cenozoic Era – 65 million years ago – today – Age of the Mammals
Types of Organisms
- Mastodons
- Saber-tooth Tigers
- Camels
- Horses
- Humans
III. Fossils
Fossilized organism, trace fossil (footprint, worm trail), cast fossil (organism decays and leaves a mold that minerals fill)
Rock Cycle
- Igneous – Formed by melting & crystallization, Basalt
- Sedimentary – Formed by sedimentation and compaction, Sandstone
- Metamorphic – Formed by heat and pressure, Marble
- Minerals move through the rock cycle in response to the conditions; weathering, erosion, heat, pressure, etc.
IV. Plate Tectonics
- Earth’s layers from the inside; inner core, outer core, mentle and crust
- Current day continents emerged from Pangea, a supercontinent that has since broken apart
- Plate Boundaries
- Oceanic as well as continental plates
- Divergent Boundary – plates pulling apart
- Convergent Boundary – plates coming together
- Transform Boundary – plates sliding against each other (faults)
- Subduction Zone – one plate being pushed onder by another

We are studying the History of Earth and Life on Earth. To learn more, click here to go to UC Berkeley’s great site for understanding geologic time.
There’s even a worksheet for taking notes as you go through the activity! geologic_time_web

Here’s a cool family outing, my friends and students. It’s a chance to look at fossils, cool beads and crystals, meteorites, fluorescent rocks, and also talk to geologists. What’s not to like!

This is a great site for information. Pictures are buried a bit, but it’s interesting to enter California in the keyword search. There are 62 species listed for the state of California! For all of my students who hope to learn more, just browse around this site.
Endemic to Siau Island, Indonesia, the Siau Island Tarsier (Tarsius tumpara) was assessed as Critically Endangered. It is restricted to a very small area and there has been a suspected population decline of more than 80% in the past. It is locally collected as food. Furthermore, an active volcano, Mt. Karengentang, dominates more than half of its geographic range. The Siau Island Tarsier is considered to be one of the 25 most threatened primates by the IUCN Species Survival Commission Primate Specialist Group. Photo © Geoff Deehan

A favorite quote is an old Buddhist saying, “When the student is ready, the master (teacher) will come”. I hope my students come to know how often I am the student and they are the teacher. I need to be at school every day – I’m afraid I’ll miss something.

Well, whoop-tee-doo! I finally made it. I’m the new Life Science teacher for the 7th Grade Transformers group at Edna Brewer Middle School in Oakland. I’m so happy I landed here. It’s the second largest middle school in Oakland, brimming with young Jedi knights of Science, and a very got-it-together staff and faculty. Another thing I really like is that I’m a big Hitchhiker’s Guide to the Galaxy fan, and my room number is, of course, 42. Andrew made this super cool graphic for my students and I to enjoy. Keep watching here for news from the classroom!

Only the best dang cupcakes in all of San Francisco – and a second Spinal Tap reference in my blog! Pancake breakfast is my current favorite. That’s what I’m talking about!
