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.

textbeeok reading pgs 159-160 (coal)

Coal, Oil and Gas – where did it all come from?

Nuclear Power
read page 162-163
This is a nice sales pitch about how we can easily and permananently dispose of nuclear waste.

This is a comedic view of the nuclear waste problem which is sadly closer to the truth.

Do Section 2 Review #1- and #8. Finish fr HW.

Earth Science U1.3 Minerals and Rocks

Note: This presentation covers minerals (that’s the part you should study). The presentation also includes background/review on atoms, sub atomic particles and orbitals – you can skip those slides for now.
02.Minerals 

 

 

 

This presentation covers rocks and the rock cycle.
Be sure you can identify three kinds of rocks, know how they are formed and how one type of rock is transformed into another type of rock. (example:how does sedimentary rock turn into metamorphic rock)

03.Rocks

Now we’ll get into a little more detail:
Igneous rocks
vocabulary:
intrusive
platonic
extrusive
volcanic
vesicules

How can you distinguish between intrusive and extrusive igneous rocks?

Earth Science U1.2 Core to Crust (The inside out story)

Earth Science U1.2 Core to Crust (The inside out story)

 

learning Objective: students will know the components of earth’s interior from the core out to the crust.  Students will be able to draw a cross sectional diagram of the inside of the earth.

Physical Structure: The earth is made of layers like shells

 

 

Write down the size and composition of each layer

 

 

 

 

 

 

Temperature of the interior of the earth.

Go back to your worksheet and write in the temperature of each layer.

Specific Heat Capacity

First some confusing vocabulary – this is Chemistry after all…..

Specific Heat Capacity ‘C’ relates the amount of heat (energy or work) needed to raise a sample of some material 1 degree C.
Think of Specific Heat Capacity as the sample’s capacity to absorb heat, so the formula should include the amount of material in the sample, ie its mass.

Q = m  C  ΔT

Q: heat absorbed by the sample
m: mass of the sample
C: heat capacity of the sample material
Δ: change or difference of…
T: temperature
The units of C is
 ‘
 
Specific heat or specific heat capacity ‘s’ is the heat capacity, which is independent of the amount of substances. It can be defined as the quantity of heat required to raise the temperature of one gram of a substance by one degree Celsius (or one Kelvin) at a constant pressure. The specific heat of water is 4.18 joules/(gram degree C).

Q =
 

Refraction

In this post, I included the lecture notes for a development of Snell’s Law (1621) using a Huygen’s Wavelet construction (c. 1670). Special case: Total Internal Reflection leads to a 10 minute mini lecture on optical fibres, T1 cables, repeaters and IR wavelength demultiplexing. Continue reading Refraction

Newton’s Laws

What you need to know:
Newton proposed 3 “Laws”
1] Inertia: An object at rest tends to remain at rest unless acted on by an eternal force. An object in motion tends to remain in motion unless acted on by an external force.
2] Force and Mass: Remember the equation F = ma where F is the force {in units of Newtons – what else could it be?}, a is acceleration and m is an experimentally determined constant of proportionality for an object. m is called the mass.
3] Law of reaction: For every action there is an equal and opposite reaction.

Easy to remember examples:
1] A body in motion, stays in motion…
2] Here’s a joke: A Physicist walks into a bar, and he says…….. “F = ma”
that’s it, pretty funny eh?
3] Push someone and they’ll push back.
