Lets get started! In a group: Create an insect out of the play dough provided. • Be ready to present your insect to the entire class. Include in presentation: # of legs wings Any significant characteristics.
What is an Insect? An insect is an animal whose body is divided into three regions with three pairs of legs on the middle region and contain an exoskeleton. They also have one pair of antennae, and one to two pairs of wings attached to the middle region if present in the adult form.
Break it Apart Look at the insect you have been given. Cut the insect out and into parts the parts you believe it has. When you think you have your insect broken down, call Ms. Masters over to get her approval. Next, glue the parts down in your notes, leaving some space between.
1. Head Head- contains one pair of antennae, two pairs of eyes, and mouthparts.
2. Thorax • Thorax- three pairs of legs and wings if present.. • Prothorax - Pair of front leg • Mesothorax – Pair of middle legs and first pair of wings present. • Metathorax – Pair of hind legs and hind wings if present.
3. Abdomen • Abdomen- the abdomen is composed of as many as eleven segments but never hears legs or wings. • A pair of spiracles are located on each segment of the abdomen. Spiracles are how the insect gets oxygen.
Exoskeleton • Insects have an exoskeleton that is made of material called chitin. • Advantages-protects the insect from enemies, keeps them from drying out, and it protects them from diseases. • Disadvantage-is it is brittle and restricts movement.
Antennae • The antennae are sensory organs for insects, they help the insect in locating food, finding remote nesting sites, and locating mates.
12 Types of Antennae • Filiform • Setaceous • Capitate • Pectinate • Plumose • Stylate • Moniliform • Ciavate • Lamellate • Bipectinate • Aristate • Serrate
