Mexican Amate Painting

March 25

We studied the Mexican art of making amate paper from mulberry bark and using that for bright symbolic paintings.  The students did two paintings each.  Squares of brown paper bag were wrinkled, treated with an India ink wash, then ironed flat when dry to simulate the color and texture of amate paper.  Everyone did so well, I hope you enjoy them.

Review for Quiz – History of Earth

March 14

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
  1. Divergent Boundary – plates pulling apart
  2. Convergent Boundary – plates coming together
  3. Transform Boundary – plates sliding against each other (faults)
  4. Subduction Zone – one plate being pushed onder by another

Geologic Time Scale

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!

Evolution Exam Review – Big Concepts and Necessary Details

February 26

I wanted to get a review sheet posted as soon as possible for students to explore – here’s an outline!

UNDERSTAND THE PEPPERED MOTH STORY BY PLAYING A VIDEO GAME!!! CLICK HERE!!

 

  1. Darwin

    1. Traveled to Galapagos Islands on the HMS Beagle
    2. Observed the different beaks of finches, and different food sources
    3. Concluded evolution happens by means of natural selection
  2. Natural Selection

    1. Organisms reproduce more offspring than can survive
    2. There is genetic variation within a population
    3. Selection happens (some better equipped, some not)
    4. Favorable traits accumulate (dominant genes)
  3. Adaptation

    1. An adaptation is an inherited trait that helps an organism survive
    2. It’s genetic – it does not happen because an organism tries harder.
  4. Evidence for Evolution

    1. Fossil Record
      1. Fossils tell how old something is (sedimentary layers/carbon dating)
      2. Fossils tell us what came first (from dating, we can create a timeline)
    2. DNA Evidence
      1. Our DNA codes for traits that are similar in different kinds of animals
      2. Species that share more similarities in their DNA base sequences aremore closely related
      3. Scientists hypothesize that if two species have similarities in theirbase sequences, they share a common ancestor
    3. Comparative Anatomy
      1. Homologous structures suggest a common ancestor
      2. Analogous structures show that very useful adaptations can evolve more than once, and in different ways
  5. Cladogram

    1. A cladogram shows the evolutionary relationships between groups ofliving things. It is like a family tree for species
    2. The closer two species are on the cladogram, the more closely they arerelated. This means they evolved apart more recently
    3. Organisms with more of the traits evolved later, so they go on the right
  6. Extinction – When a species not longer exists, due to:

    1. Increased Competition -­‐ organisms share food, water, and shelter and when it starts to run out, they compete with each other
    2. New Predators -­‐ new species can enter an area and prey on animals that do not have adaptations to protect themselves
    3. Loss of Habitat -­‐ habitats can get destroyed by pollution, natural disasters such as floods, storms, fires
    4. Catastrophic Event -­‐ asteroids can destroy life on the planet
  7. Speciation – The formation of a new species. Three stages:

    1. Isolation -­‐ happens when a population becomes divided by an event (such as floods, volcanic eruptions, mountain formation, earthquakes, and storms)
    2. Adaptation -­‐ as the environment changes, the population that lives there undergoes natural selection, and each separated population becomes adapted to their environment
    3. Differentiation -­‐ happens when the isolated populations become so different that they can no longer interbreed, even if they could unite again.

Endangered/Extinct Species

February 23

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

Sometimes it's the bit between the numbers in your grade book that counts

February 12


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.

Transformation

February 12


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!

The earliest stage in the lifecycle of the Bug Lady can be traced back to the Midwest in the early 1990s. Elementary students near Illinois State University were introduced to live insects from the ISU Entomology Lab by an inspired graduate student and secondary teacher.

Wings unfurled, she expanded her range as the Associate Director of Education for Lakeview Museum of Arts and Sciences in Peoria. The Bug Lady appeared frequently in school outreach and after-school enrichment programs, summer camps, senior homes, and occasionally on local news. In 2001, she served as President of the Peoria Academy of Sciences, reviving the Entomology section and encouraging girls to pursue careers in science.

Like the Monarch butterfly, she then migrated to the west coast, basking in the California sun and tending to her newly hatched larva (baby Sophie). “In my mind and my heart, I’ve always been the Bug Lady, not so much for the knowledge I’ve acquired regarding insects, but more for the feeling that I’m in a constant state of metamorphosis – ever changing.”

After a long diapause, the imago of Bug Lady was sighted in Alameda summer programs, along with her assistant, Bug Gurl. She returned to the science classroom in Oakland and taught middle school integrated science for 12 years. is now taking flight in cyberspace to share her love of insects, science, and life in general with enthusiasts of all ages.
