Learn the difference between a physical property and a chemical property. In this video, I cover 9 physical properties and several chemical properties in order to help you understand the difference between these different types of properties.

Paleozoic EraPaleozoic era was 544 to 245 million years ago
Paleozoic means “ ancient life” and is part of the phanerozoic eon along with the cenozoic, and mesozoic eras
Let’s hit some highlights of this era
Early during the Paleozoic era trilobites, echinoderms, and other marine invertebrates such as coral dominated the oceans.
Jawless fish also lived during this era
Evently sharks and other bony fish appear
However, as time passed life did not remain in the sea.
Land plants began to appear such as ferns and some trees later in this era
Life was also crawling out of the ocean
The first vertebrates appeared Among these vertebrates was a tetrapod which was a vertebrate that could live on land
Other vertebrates would appear including snakes,crocodiles,
Reptiles and insects scatter throughout the world and amphibians appear
The supercontinent Rodinia brook apart early in this era, but by the end of the era the supercontinent Pangea was formed.

How does oxygen enter the body. The respiratory system is designed to exchange oxygen for carbon dioxide. The respiratory system is vital for the production of ATP. The mitochondria uses oxygen in order to produce ATP. In addition, it is designed to get rid of the waster product carbon dioxide.

Learn what an ion is in chemistry. You can produce a charged atom by taking a neutral atom and adding or removing one or more electrons which are called an ion
A positively charged ion is a cation
A negatively charged ion is called an anion.

The cell membrane surrounds the cell and protects the cell, communicates with other cells, and controls what enters and exits the cell.
The cell membrane is made of phospholipids which have a polar and nonpolar end.
The cell membrane also has proteins and carbohydrates.
In this video, I cover what the cell membrane is made of and the structure and function of the cell membrane.

Learn the difference between myopia and hyperopia
Myopia which is also called nearsightedness is when you can see items up close clearly and distance objects are blurry.
Hyperopia is the opposite. You can see distant objects clearly and objects that are close are blurry.

In your middle school science class or in Earth science you will hear about the lithosphere.
The Lithosphere is the top rigid, rocky portion of our earth
There are two types, the continental lithosphere, and the oceanic lithosphere.

The lithosphere is also divided into large tectonic plates.
These plates were one large continent called Pangea that broke apart.

Learn how to set up a basic tree diagram and then solve for the total number of choices and the probability of a certain event.
In this tree diagram probability example John has to decide what to wear to school. He needs to decide on his shirt, pants, and shoes.
The tree diagram will help you figure out the total outcomes and the probability.

Reading a ruler that measures in inches.

Reading a ruler can be a little tricky. What do all of these marks represent?
The ruler is divided into inches which are represented by numbers and then each inch is subdivided into smaller equal units.
In this video, I use a ruler divided into half an inch, one fourth an inch, and one eighth.
With a little practice you will find easy an inch ruler or tape measure can be easy.
