Learn how to calculate the area of a composite figure. A composite figure is made up of simple Geometric shapes. In order to find the area you decompose the geometric shapes and then add the area of each shape together for the area of the composite figure.
***** In the first example I make a mistake with the area of the triangle. 1/2 of 54 = 27 not 28.
So the answer should be 63 + 27 = 91 m squared
Sorry for the mistake.

In this video, I cover the indendent variable,the dependent variable, and control variables.
The independent variable is what you manipulate, the dependent variable is the variable you measure, and control variables need to remain constant to insure accurate results.

Phytoplankton and zooplankton plankton are organisms found in the ocean and bodies of freshwater that drift and cannot swim against the current.
In this video, I would like to talk about two types of plankton
Phytoplankton and zooplankton.


Zooplankton is derived from Greek and means animal drifter
Although most zooplankton is microscopic, some are larger such as jellyfish.


Phytoplankton means plant drifter
Phytoplankton is photosynthesizing microscopic organisms found in the upper sunlit layer of all oceans and bodies of freshwater on Earth.
Phytoplankton is sometimes called the grasses of the sea. Like land plants, they produce lots of oxygen through photosynthesis.

Learn what buoyancy is and Arhimedes principle.If you have ever tried to push a beach ball underwater you know how difficult this can be because the water pushes upward against the beachball. This upward force is called buoyancy.
Which is the ability of a fluid like water to exert an upward pressure.

If you drop an object in water which is a fluid then the water level will rise. In other words, the water will be displaced. The weight of this water that is displaced will be equal to the buoyancy force.

Archimedes principle in simple terms states that the buoyant force of an object is equal to the weight of the fluid displaced by the object.

Learn proportion basics. In this video, I show you how to work problems in which you find the value for x in a proportion.
Example problems include,
3/5= x/15
x/6 = 15/18
In order to solve these problems you cross multiply and then solve for x

In this video I go over what an ecosystem is and I show several examples including microecosystems,meso ecosystems and biomes.

Natural resources can be classified as renewable and nonrenewable resources. Natural resources can be classified as renewable or nonrenewable
A renewable resource can be replaced at the same rate in which the resource is used
Common renewable resources used to produce energy include,
Solar, like these solar panels converting solar energy into electricity. A nonrenewable resource is a resource that forms at a rate that is much slower than the rate that it is formed. Coal is an example. It takes millions of years to create coal and once it is used up it is no longer available
You can use CON to remember three popular nonrenewable resources.
This stands for
Coal
Oil
Natural Gas

I cover four types of friction. Static, fluid, kinetic, and rolling.
Static friction in which two surfaces are not moving past each other.
Sliding or Kinetic friction where 2 surfaces slide past one another.
Rolling friction between a rolling object and surface it rolls on.
Fluid friction is friction that occurs when objects move across or through a fluid.

As the moon rotates around the earth it travels through phases.
The alignment of the sun, earth, and moon create the phases.
I use an orrery to explain the moon's alignment during,
new moon, waxing crescent, ist quarter, waxing gibbous, full moon, waning gibbous, last quarter, waning crescent, and back to new moon.
The sidereal period is 27.3 and the moon is measured against stars.
The synodic period is 29.5 days and the moon is measured against the sun.

Layers of the Earth based on chemical composition and physical properties
Earth can be divided into three layers based on chemical composition: the crust, the mantle,
and the core.
Earth is also divided into layers based on physical
properties, such as whether the layer is solid or liquid.
The five physical layers are the lithosphere, asthenosphere,
mesosphere, outer core, and inner core.
