The Human Eye

The human eye belongs to a general group of eyes found in nature called “camera-type eyes.” Just as a camera lens focuses light onto film, a structure in the eye called the cornea focuses light onto a light-sensitive membrane called the retina. 

The Human Liver

The liver is an abdominal glandular organ in the digestive system. It is located in the right upper quadrant of the abdomen, under the diaphragm and on top of the stomach. The liver is a vital organ that supports nearly every other organ to some capacity.

The Human Tongue

Though the tongue may seem like a simple organ, it has a wide range of purposes, such as licking, breathing, tasting, swallowing and articulating speech. Its many talents are due to the construction of the tongue.

The Human Ear

The ear isn’t just the hearing organ. It is a complex system of parts that not only allows humans to hear, but also makes it possible for humans to walk.

The Human Brain

The human brain is the command center for the human nervous system. It receives signals from the body’s sensory organs and outputs information to the muscles. The human brain has the same basic structure as other mammal brains but is larger in relation to body size than any other brains.

Ancient crocodiles may have swam across the Atlantic Ocean

What is the Scientific Method?

How do bees fly? Why does water freeze in cold temperatures? How does the wind blow? Our world is full of lots of curious events, and science aims to figure out why these events happen. To do this, we use the scientific method. 

What is Natural Selection?

Did you know that more than 99% of all species that have ever lived on our planet have died out? Humans, blue whales, giraffes, mice, bacteria, and everything else we see around us are the exception. We’re the survivors of a process called natural selection.

What is Microbiology?

Microbiology is the study of tiny biological creatures invisible to the eye like bacteria, viruses, and other microbes. Although these organisms are too small to see, they still have a dramatic impact on our lives. Microbes exist all around us. They live in water, soil, on our bodies, and even the air we breathe.
