Slide 2:

FROG TOAD smooth, moist skin rough, drier skin no warts on body have warts on body narrower body and waist broader, flatter body live near or in water live on land, breed in water only longer hind legs for hopping webbed hind feet for swimming shorter hind legs, walks rather than hop eggs are in massive lump of cloudy jelly eggs are long and stringy, wrapped around water plants WHAT IS THE DIFFERENCE BETWEEN A FROG AND A TOAD ?

Slide 5:

A butterfly usually lays 200-500 eggs on plant leaves and stems. Eggs from different butterflies are different shapes and sizes. The caterpillars hatch from the eggs about 5 days later. The caterpillar is also called the larva. Caterpillars first eat their eggshell, then they eat lots of leaves. Each time the caterpillar grows, it needs to shed its old skin or molt . They usually molt 5 times. After a few weeks the caterpillar stops eating and growing and looks for a place to change. The caterpillar sheds its skin for the last time and becomes a pupa . The pupa stays inside a hard shell called a chrysalis . Inside the chrysalis, the pupa is changing from a caterpillar's body to a butterfly's body . The adult butterfly emerges from the chrysalis after several weeks. The butterfly looks for another butterfly to mate with. After mating, the female butterfly lays her eggs. Adult butterflies usually live for only 2 weeks!

Slide 9:

Ant Life Cycle The life cycle of the ant consists of 4 stages Fertilized eggs produce female ants (queens, workers, or soldiers); unfertilized eggs produce male ants. Egg : Ant eggs are oval shaped and tiny (they are on the order of 1 mm long, but the queen's egg is many times larger). Larva : The worm-like larvae have no eyes and no legs; they eat food regurgitated by adult ants. The larvae molt (shed their skin) many times as they increase in size. Pupa : After reaching a certain size, the larva spins a silk-like cocoon around itself (against a solid object, like the wall of the chamber) and pupates. During this time the body metamorphoses (changes) into its adult form. Adult : The pupa emerges as an adult. The entire life cycle usually lasts from 6 to 10 weeks. Some queens can live over 15 years, and some workers can live for up to 7 years.

Slide 10:

Life Cycle of Cicada The cicada has the longest life cycle of any insect, ranging from 2 to 17 years. A rice-shaped egg is laid in tender twigs and plant stems. The egg hatches into a nymph and drops to the ground. The nymph burrows into the soil and crawls to a tree root (using its claw-like front legs). The nymph will eat the tree's sap. The nymph stage lasts up to 17 years in periodical cicadas; dog day cicadas have a shorter life cycle. There is no pupa stage. When the nymph is fully grown and the temperature is optimal, the nymph tunnels to the surface and goes through its final molt (shedding its hard outer skin) and emerges as a winged adult. When the wings dry and harden, the cicada flies in search of a mate.

Slide 11:

Mealworm Lifecycle The mealworm is NOT a worm. It is the larval stage (grub) of the yellow mealworm beetle. Although the grub looks a bit like a worm, the mealworm has six small, jointed legs. Both the larva and the beetle are nocturnal (active at night), but they are also active during the day. Life Cycle : The mealworm undergoes complete metamorphosis. The female mealworm lays hundreds of tiny, white, oval eggs, which hatch into tiny mealworms - it takes from 4 to 19 days to hatch. Each mealworm eats a tremendous amount and grows a lot, molting (shedding its exoskeleton) many times as it grows. It then enters the pupa stage (this stage lasts up to 9 months). The pupa does not eat and seems inactive, but it is transforming itself into an adult. After pupating, a white adult dark wing beetle emerges from the pupa -- it soon turns brown and then almost black. The adult lives for a few months. The entire life cycle takes about a year.

Slide 12:

Ladybug Life Cycle eggs - Ladybugs lay masses of tiny, yellow, elongated eggs on a leaf. They hatch in 3 to 7 days. larva - Each egg hatches into a long, six-legged larva, which eats and molts (sheds its skin) many times as it grows. The larval stage lasts 2 to 4 weeks. pupa - After reaching full size, the larva attaches itself to a plant leaf or stem (by its "tail"). The larval skin then splits down the back, exposing the pupa. The pupa is about the size of the adult but is all wrapped up, protecting the ladybug while the it undergoes metamorphosis into its adult stage. adult - The adult ladybug emerges from the pupa. It will mate, the female will lay eggs, and the cycle begins again.

Slide 13:

Mosquitoes undergo complete metamorphosis; they go through four distinct stages of development during a lifetime. The full life-cycle of a mosquito takes about a month. Eggs : After drinking blood, adult females lay a raft of 40 to 400 tiny white eggs in standing water or very slow-moving water. Larvae : Within a week, the eggs hatch into larvae (sometimes called wrigglers) that breathe air through tubes which they poke above the surface of the water. Larvae eat bits of floating organic matter and each other. Larvae molt four times as they grow; after the fourth molt, they are called pupae. Pupae : Pupae also live near the surface of the water, breathing through two horn-like breathing tubes on their back. Pupae do not eat. Adult : An adult emerges from a pupa when the skin splits after a few days. The adult lives for only a few weeks. Mosquito Life Cycle

Slide 14:

Salmon live in the sea but reproduce in fresh water (in a stream or lake). They are amazing fish that live in fresh water during their early life, mature in salt water, and then return to fresh water to breed (and then die). Life Cycle : Reproduction : Salmon live most of their life in the sea, but when they are mature and ready to breed, they enter fresh water to spawn (reproduce), traveling to a stream or pond high in oxygen. The female digs a nest in the gravel (called a redd) with her tail. She then pushes her thousands of eggs into the nest and the male milks the eggs, fertilizing them. Most salmon die after spawning. The Eggs Hatch and Grow : The newly-emerged salmon still have a food sac attached to them. When the food sac is used up, the salmon fry emerges from the nest - and must find food (like insects) for the first time. As the fry matures, it becomes camouflaged. When it becomes silver-colored, it will be called a smolt. After growing for a while, the smolts swim downstream to the sea.

Slide 15:

Adapting to Salt Water : When smolt reach the estuary (where the river meets the sea), a process begins in which their body changes, allowing them to soon live in salt water. Maturing at Sea, then Returning Home : The salmon lives in the sea until maturity (1 to 7 years, depending on the species); some migrate thousands of miles in the sea. They then return to the place where they hatched and continue the cycle. No one knows how salmon return home -perhaps they remember the distinctive set of smells along the way. On their journey home, they do not eat at all, they often change color, their muscles soften, and they will die soon after spawning.
