Water as a polar molecule

• A water molecule is made of 2 Hydrogen atoms and 1 Oxygen atom that are covalently bonded together.

• What does this mean?

• Water is a polar molecule! And looks like this:

Because water is a polar molecule:

• It acts like a magnet -

• Has cohesion -

• Has adhesion –

• Water molecules dissolve other polar molecules in the environment and inside our bodies!

Scientific Names

1. System to name all living things was finalized by a Swede named Carolus Linneaus.

2. Established system using Latin…3. All types of living things have a scientific

name that consists of a genus and species name.

4. This allows us to use a common language when discussing living things.

For dogs and dog-like animals the genus is CanusFor dog, the scientific name is: Canus lupusFor the coyote it is : Canus latrans (dog barking)For modern man it is: Homo sapiens, which means man thinking.When written, the scientific name is always underlined, or it is typed in italics.

Big Leaf Maple

Acer marcophyllumMeaning: Roman, big leaf-very hard wood, good for furniture-can be a source of maple syrup-seeds are wind disbursed

Black Cottonwood

Populus trichocarpaMeaning: Roman, hairy fruit- Large and fast growing- Seeds are cottony and wind dispursed- Grows in wet areas

Western Hemlock

Tsuga heterophyllameaning: Japanese, different leaves- Needles different sizes- Grows well in shade- Grows tall when there are canopy openings

Vine Maple

Acer circinatumMeaning: Roman, round- Can grow long and viney- Seeds wind disbursed- Very colorful fall colors

Western Red Cedar

Thuja plicataMeaning: Greek, pleated- Can live for a very long time (up to 1000 years)- Wood is very disease resistant (cedar chests)- Good for building house exteriors but

Red Alder

Alnus rubraMeaning: Roman, red- Lives near water- Pioneer species – can live on nutrient poor soil- Can fix nitrogen so other trees/plants can use

it.
