Insect Anatomy

Do insects have bones? Insects do not have a backbone like humans and many other animals do. In fact, insects do not have any bones; they have a hard exoskeleton instead. "Exo" means outside, so that means that the skeleton is on the outside of the insect's body instead of on the inside like in our bodies. Did you know that insects are related to crabs and lobsters, which also have exoskeletons?

Thinking Scientifically: Animals that have a backbone are called vertebrates - can you think of any vertebrates?. Any animals that do not have a backbone, like insects, are calledinvertebrates.

All insects have three main body parts: a head, thorax, and abdomen. It's important to know these parts in order. It helps to think of the thorax as being sandwiched in between the head (which is at the top just like your own head) and the abdomen (at the bottom).

Head: An insect has a small head that is a lot like your own head because it holds the insect's brain, eyes, and mouth. Insects also have special feelers called antennae that stick out of the top of their heads. They use their antennae to smell and feel because they do not have noses and hands like we do.

Thinking Scientifically: You may have heard the word antenna before, but have you ever heard anyone say antennae (pronounced: an-ten-I)? Did you know that "antennae" is just the plural form of the word "antenna"? When we say "antenna," we are talking about one and when we say "antennae," we are talking about two or more, just like when we say "shoe" we are talking one shoe, and when we say "shoes" we are talking about a pair of shoes.

Eyes: Insect eyes are much different from human eyes (called simple eyes). In fact, insects do not even see things the same way we do! They have two compound eyes with many different lenses to see out of instead of just one lens in each eye like we do. Each compound eye can have anywhere from 2 to 30,000 different surfaces that are very sensitive to light. Compound eyes cannot see very much detail or things that are far away. They can see extremely quick movements and things that are close to them, though. If insects did not have compound eyes, they would have a very difficult time surviving and finding food! Have you ever tried to swat a fly? What happened when you got close to it? It probably flew away the second you got close enough to swat it. That is because a fly's compound eyes bulge out of its head so it can see motion all around its body and see when you are coming closer to it.

Thinking Scientifically: Some insects, like grasshoppers, have compound eyes and normal eyes (called simple eyes)! With simple eyes, they can see a lot more detail and see things that are far away.

Exoskeleton

From Wikipedia, the free encyclopedia

The discarded exoskeleton of a dragonflynymph

An exoskeleton is the external skeleton that supports and protects an animal's body, in contrast to the internal skeleton (endoskeleton) of, for example a human. In popular usage, some of the larger kinds of exoskeletons are known as "shells". Examples of exoskeleton animals include insects such as grasshoppers and cockroaches, and crustaceans such as crabsand lobsters. The shells of the various groups of shelled mollusks, including those of snails, clams, tusk shells, chitons andnautilus, are also exoskeletons.

An Introduction

My background is in animation at Disney ILM and PDI/Dreamworks.

As an introduction I would like to show this short clip of a children's show 'Blue Peter' from 1992, in which I explain the computer animation work done in the Lion King.

The Lion King is currently being shown in theaters as a re release in 3D.

The technology used for the herd of wildebeests is the same technology used to create a colony of ants in the most recent Indiana Jones movie. This will tie into our class on drawing ants, and our guest speaker and Nathan's dad Steve, who was the animation supervisor for The Kingdom of the Crystal Skull in 2006.

I will bring a few of my drawings and paintings to show the class.

We will focus or first set of drawing classes on

- Insects

- Line Drawing, using basic shapes to get the contour then adding detail

- Shading to add depth to the drawing

I will sprinkle in a few classes on how animation is created.

The first function of the artist is to observe, to study nature.

We will start by creating a collage of insects found in the swamp. We will draw the insects together in class, using reference material from the Academy of Sciences, "What makes an insect an insect?" to help us better understand what we are drawing.

Students have read a story in class called 'Around the Pond Who Lives Here?", which explains flora and fauna found in a pond.
