• RED SLIDE: These are notes that are very important and should be recorded in your science journal.

• BLACK SLIDE: Pay attention, follow directions, complete projects as described and answer required questions neatly.

• Keep an eye out for “The-Owl” and raise your hand as soon as you see him.– He will be hiding somewhere in the slideshow

“Hoot, Hoot”“Good Luck!”

New Area of Focus: Soil

• What is the connection between weathering and soil?

• Weathering is the process that will, overtime,

• Weathering is the process that will, overtime, create soil.

• Activity! Defining Soil.

– Please examine a sample of soil and record what you find in your journal.

– Please work in a tray and keep your table clean.

• Fungal Filaments in the soil (Electron Microscope)

• Head of a Nematode (roundworms) Trillions are in the soil of your backyard.

• Microscopic Soil Mite

• All sorts of important micro-organisms.

• Without these organisms, plants would not grow.

• Without these organisms, plants would not grow. No plants, no energy for any of us.

• What does healthy soil look like?

• Color is very important to a soil scientist. – Color helps to tell what the soil is made of and

therefore its health.

• Iron turns rust color when it mixes with oxygen (oxidation in Australia)

• Activity! Identifying soil based on color– Observe each sample.– Create a smear on journal.– Describe the color of the smear and make an

inference into the health of the soil.

New Area of Focus: Particle SizeThe type of soil depends upon the size

of it’s particles.

New Area of Focus: Particle SizeThe type of soil depends upon the size

of it’s particles.

• Why learn about particle size? Seriously!

• This large cobble would not be good to make a smooth road.

• Is to coarse to build an earthen dam with?

• The type of particles determine the type of sand paper.

• Coarse gravel and cobble are a much better material than clay for drainage.

• Is this good particle size for a bunker at a golf course?

• Answer! No.

• The combinations of particle size can determine how well plants will grow in soil.

• The particle size of sand is important to help increase traction on ice.

• Understanding particle size is very important as we rely on earthen materials everyday.

• Gravel (2cm-7.5cm)Gravel (2cm-7.5cm)

• This sand is much more coarse than the fine grain sand near the ocean.

• Spectrum of gravel– Very Coarse Gravel larger than 1.25-2 inches

(32-64mm).– Coarse Gravel 16-32 mm– Medium Gravel 8-16mm– Fine Gravel 4-8 mm– Very Fine Gravel 2-4mm

“I’ll bet your doing it again.”

• Is there an easier way to separate soil into different particle sizes?
