Learn about the four Spheres of the earth.
The earth can be divided into four major spheres.
The biosphere which means life.
The hydrosphere which makes up all the water of the earth
The atmosphere which is the air of the earth
The geosphere which is all of the rocks, soil, and layers of the earth.

These four spheres of the earth allow life to exist on planet earth

Selective breeding (also called artificial selection) is when humans use animal breeding and plant breeding to develop offspring with traits they desire.
Selected breeding has been practiced for years with plants and animals.
Selective breeding has been used with horses, dogs, rice, wheat and corn

Let’s look at some examples,
Look at these two dogs
This Chihuahua mix and Great Dane shows the wide range of dog breed sizes created using selective breeding

Transverse waves are waves in which the oscillation is at a right angle to the direction of the wave.
A transverse wave has a crest, trough, wavelength, resting point, wavelength, and frequency.
The following is a quick summary of the video.

The Law of Conversation of Mass states that the mass of the reactants must equal the mass of the products in all chemical reactions.
I use a simple demonstration to show this point. I use baking soda and vinegar which is a simple chemical reaction, to demonstrate the law of conservation.
Correction:
0:41 I accidentally said grams instead of ounces while weighing the materials. My mistake.

Matter is most often found as either a solid,liquid or a gas. Matter can also move from one phase to another when heat or energy is added or subtracted. In this video, I illustrate this with a triangle that show how matter moves from one state to another.

Igneous Rocks are created from molten rock that is either on the surface (lava) or inside the Earth ( magma)

Excretory system
The excretory system removes waste and toxins from the human body.
Your skin eliminates waste by sweating.
Your lungs eliminate carbon dioxide.
Your kidneys filter over 180 liters of blood in order to produce urine.
The kidneys filter waste like urea. This liquid that is collected is called urine.
Your kidneys are made up of millions of filtering units called nephrons.

10 Mutualism Examples

Mutualism is a symbiotic relationship in which both organisms involved in the relationship benefits from the relationship.

Many times mass and weight are used to describe the same thing. However, these two measurements are different. In this video, I explain the difference between mass and weight.
Mass is a measure of how much matter something contains, which equals the number of atoms in it
Weight is a measure of how strongly gravity pulls on something

The SI unit for mass is kilograms
The SI unit for weight is the newton N

Sedimentary Rocks are rocks formed from rock fragments and organic matter.

Sedimentary rocks are formed from pre-existing rocks or pieces of once-living organisms. They form from deposits that accumulate on the Earth's surface or under the ocean. The particles that form a sedimentary rock are called sediment and may be composed of minerals or organic matter.
The following rocks are sedimentary Rocks
Shale, Conglomerate, Limestone, Sandstone

Soil horizon and profile explained.
Soil is essential for many activities like plants growing and much of the food we eat.
In this video, I cover the difference between soil profile and horizon and review the characteristics of horizons O A E B C R
o = litter
b = topsoil
e = eluviated
b = subsoil
c = parent material
r = bedrock

Examples of parasitism

This innocent looking bird called a cowbird lays her eggs in another birds nest and expects the unsuspecting mom to raise their young. If this bird kicks her eggs out of the nest the cowbird may destroy her nest. This is just one example of parasitism.

Parasitism is a symbiotic relationship in which one organism benefits and another organism is harmed and in some cases may die.
Let’s take a look at examples

Mosquitoes These annoying pests will show up at most picnics and start trying to have a meal at your expense. mosquitoes are carriers, or vectors, for some of humanity’s most deadly illnesses, and they are public enemy number one in the fight against global infectious disease. Mosquito-borne diseases cause millions of deaths worldwide
In a similar fashion, ticks will do the same to you, dogs, livestock. The latch on to their host and start eating. Ticks can infect their host with many diseases including Lyme disease.

Many worms are parasitic.
Leech
A leech is a segmented worm that attaches to a host like you and gets a meal from their blood. They secrete a chemical that actually prevents the blood from clotting.
If present in great numbers on a host, these can be debilitating, and in extreme cases, cause death.

E. coli
There are hundreds of different types, or strains, of the bacteria E. coli (Escherichia coli). Most of these are harmless and live in the intestines of healthy people and animals. But some strains of E. coli make a strong toxin that can cause a severe infection.

Mistletoe This plant you will see high in trees is actually a parasite. Mistletoe will attach to their host tree or shrub and then extract water and nutrients from the host plant.

Bacteria-- Parts of a bacteria cell
A bacteria cell is classified as a prokaryotic cell because it does not have a nucleus or membrane-bound organelles.
A bacteria cell does have genetic material, but it is not organized in a nucleus.
