Ch 13.1 Human Organ Systems

Here is a really good explanation of the 4 types of tissues in the human body.

What you need to know:

Be able to name 11 body systems and describe what each system does.

Watch the video and fill in in your worksheet “Chapter 13 Section 1 Notes – Day 2 – Organ Systems.

Earth Science Unit 7.1 The Origins of the Universe?

There have been a number of scientific observations which led to the development of the Big Bang Theory. There observations are reported as observable fact without editorial judgement.

1] the spectra of light reaching us from distant stars appears shifted towards the red (lower energy) wavelengths.
2] there is an observable background radiation of 3 Kelvin everywhere we look.

Here’s what the Big Bang Theory says:

Earth Science Unit 6.3 Climate and Weather

Learning objective:
To understand the distinction between climate an weather
To understand how low and high pressure areas affect local weather
To understand how storm fronts are formed

Do you know the difference between Climate and Weather?

Earth Science Unit 5.5 Ocean Waves and Tides

Essential Questions:
What are waves?
What are the properties of ocean Waves?
What powers ocean waves?
What happens when waves reach the shore?
What are tides?
What’s the moon got to do got to with it?

What are waves?

sample board problems wavelength, period, frequency, amplitude
Sound’s speed in seawater is of particular interest to anyone trying to use sonar or other underwater exploration techniques. The speed of sound in sea water is, on average, about 1560 m/s, or 3490 mph. But ocean waves are much slower:

Wave velocity is the speed of the wave. Velocities of normal ocean waves are about 90 km/hr while tsunami have velocities up to 950 km/hr (about as fast as jet airplanes), and thus move much more rapidly across ocean basins.

Earth science Unit 5.4 Ocean Currents

transport mechanisms:
the Gulf Stream
polar melt flow
destruction of the polar ice cap, impact on the Gulf Stream and potential mini ice age in Europe

Modeling the Coriolis Force

Ocean Currents Iken Edu

Identify ocean currents (worksheet)







The Gulf Stream

From memory: sketch the north Atlantic ocean, draw and annotate the cold and warm sections of the gulf stream.

Q: England is as far north as central Canada yet its climate is about the same as New York’s.   Explain why this is and why London is usually foggy.

The Gulf Stream is driven by the difference in water temperature between waters near the equator and waters near the north pole.

The Gulf Stream is a convection current.

Earth Science Unit 5.0 The Oceans

Lesson 1 of Summer School Semester 2 Earth Science

Oceanography is simply the study of the oceans. We’ll be learning the geography of the oceans and the physical properties of the ocean as well as the water it contains.

Earth Science Unit 3.2 Renewable Energy

Renewable Energy is defined as energy produced from resources which will not get consumed and run out.

There are 4 major types of renewable energy sources:

Geothermal: uses the heat of the earth

Hydroelectric: recovers energy from gravity when water flows down from a lake (reservoir) through a dam.

Wind: produced electricity when wind turns a motor.

Solar: concerts energy from the sun into electricity.
