Learn how to calculate the scale factor. You can use scale or model or scale over the actual or the original in order to determine the scale.factor.

Our blood helps keep us alive.
Your blood makes up around 7% of your body weight
This equals between 1 and 1 and a half gallons 4.5 to 5.5 liters
Your blood is considered a connective tissue.

Our blood has many important functions.
Here is a list of some of the major jobs
Transports oxygen to each cell.
Removes waste material like carbon dioxide.
Helps regulate your temperature and ph levels.
Fights disease and helps the immune system do its job.
Blood transports nutrients, such as sugars, fats and proteins, amino acids,
Along with hormones which are your chemical messages of the endocrine system.
It is made up of red blood cells, white blood cells, platelets, and plasma.

In this video, I show you how to find the exact square root of a number using a factor tree.
A factor tree allows you to find the prime numbers of a number.
Once you know the prime numbers then you can easily find the square root.
In this video, I find the,
The square root 50
The square root of 9
The square root of 25
The square root of 12

There are several diferent types of estuaries.
An estuary is a body of water that has fresh water entering and is also open to the ocean. An estuary is a semi-enclosed, coastal body of water, that is connected to the open sea, with fresh water draining into it.
If you look at the state of Georgia you can see the Savannah river run through it. The Savannah river dumps into the Atlantic ocean and creates an estuary. Here is what a small portion of this estuary looks like.

Estuaries are known for their brackish water which is a combination of salt and fresh water. Estuaries have been called the "Nurseries of the Sea." because of the many phytoplankton that is found there help the food chain and provide food for many organisms.

Learn how to find the cube root of 64. The number 64 is a perfect cube.

What makes an arachnids an arachnid? Spiders and mites are examples of arachnids. First arachnids are arthropods and in addition, they have 8 legs, no antennae, and no wings.
Spiders are arachnids and come in a variety of sizes and shapes.
Spiders are not insects, but instead, they are Arachnids.
Although a spider and insect have many of the same traits spiders have only two body segments and eight legs instead of six.

Plant root structure explained.
The root of a plant helps anchor the plant and absorb water and nutrients from the soil.
There are two main types, a taproo nd a fibrous root.

In this video, you will learn about transport across the cell membrane. I cover active and passive transport, diffusion, osmosis, and endocytosis and exocytosis.
Passive transport involves diffusion and osmosis and does not require energy. Objects move from a high concentration to a low concentration.
Active transport requires energy.
I answer questions like, is facilitated diffusion active or passive transport.

Tundra biome facts. In this video, enjoy pictures and video clips of this cold biome. The tundra can be divided into two types. The arctic tundra and the alpine tundra. The arctic tundra is found in the north near the poles and is very cold and treeless. The alpine tundra is found at the top of mountains and has a similar climate as the arctic tundra.
In North America, you will find the arctic tundra in Alaska and some cities would include Barrow Alaska, Aklavik, Fort McPherson, Inuvik, Iqaluit, Old Crow, Qausuittuq and Tuktoyaktuk. These cities are all on the northernmost frontier, in the Northwest Territories, the Nunavut provinces and the Yukon Territory. Each of these cities has very long winters and short summers.
The alpine tundra can be found in the rocky mountains, Alps, and Pyrenees mountains

Understand the concept of a ratio and use ratio language to describe a ratio.
A ratio shows the relative sizes of two or more values.
A ratio can be expressed three ways:
• Using the fraction bar as in 2/3
• Using a colon symbol as in 2:3
• Using the word “to” as in 2 to 3.
Write each ratio using the other two ways:
1. The ratio of 4 inches to 32 feet.
4 inches: 32 feet or 4 inches/32feet
2. The ratio of 5 students: 1 class
5 students/ 1 class or 5 students to 1 class
3. The ratio of 4 boys/6 girls
4 boys: 6 girls; 4 boys to 6 girls

4. 2 mountain bikes to 8 road bikes

2 mountain bikes: 8 road ride bikes or 2 mountain bikes/ 8 road bikes

Lichen is a combination of algae and fungi. It is estimated that 6% of the land on Earth is covered with lichen. This organism is a combination of algae or cyanobacteria living among fungi.
This mutualistic relationship allows the lichen to live in areas that would be impossible for plants.

Why is Venus the hottest planet? Venus is a terrestrial planet and is the second closest planet to the sun. It would seem logical that Mercury the closest planet to the sun would be the hottest of all of the planets. Mercury is very hot with high temperatures of + 840 °F (+ 449°C) but also on the side of Mercury facing away from the sun it gets very cold - 275 °F (- 170°C) This is because Mercury has a very thin atmosphere and cannot trap in the heat. The thin atmosphere is similar to you wearing shorts and a t-shirt at the beach. The heat is not trapped next to your skin.
Venus, on the other hand, has temperatures of + 870 °F (+ 465°C)
This is hot, hot, hot. Remember, water boils at 212 degrees Fahrenheit, 100 Celcius and lead melts at 621 Fahrenheit 327 celsius
Why is Venus so hot. First, it is the second closest planet to the sun.
Venus is 0.723 AU 67.2 million miles 108.2 million km from the sun compared to
Earth which 1 AU 93 million miles 149.6 million km
This alone causes Venus to be hot. However, it is hotter than Mercury. The atmosphere of Venus is made up almost completely of carbon dioxide. It also includes small doses of nitrogen and clouds of sulfuric acid. The atmosphere is so thick on the surface it would feel 90 times heavier than Earth's atmosphere. The surface pressures are similar to diving 3,000 feet beneath the ocean. This thick atmosphere traps in the heat close to the surface in the same way a thick jacket traps heat next to your skin.
