Background Information: Below is a quick background on the types of organisms Learn about different types are organisms that live in the ocean. Design their own creature using the information they have gained about various adaptations and why organisms use them. Materials that are discussed in the movie.

Crustaceans: There are approximately 39,000 species of crustacean including crabs, lobsters, shrimps, barnacles and woodlice. Most are aquatic and of these, most are marine species. Like Learn about different types are organisms that live in the ocean. Design their own creature using the information they have gained about various adaptations and why organisms use them. Materials all arthropods, crustaceans have a hard external skeleton (exoskeleton). They have two pairs of antennae, a pair of mandibles, two pairs of maxillae (mouth parts used for eating) on their heads, a pair Learn about different types are organisms that live in the ocean. Design their own creature using the information they have gained about various adaptations and why organisms use them. Materials of appendages on each body segment (head, thorax, and abdomen) and a pair of compound eyes (usually on stalks).
Jellies, corals & anemones: Cnidarians are invertebrates that have radial symmetry, a Learn about different types are organisms that live in the ocean. Design their own creature using the information they have gained about various adaptations and why organisms use them. Materials gastrovascular cavity and cnidocytes (unique cells that function in defense and the capture of prey). Hydra, sea anemones and corals, jellyfish are classed in the phylum Cnidaria. The two basic body form of Cnidarian is Learn about different types are organisms that live in the ocean. Design their own creature using the information they have gained about various adaptations and why organisms use them. Materials medusae or polyps. Medusae, such as adult jellyfish, are bell-shaped with tentacles hanging down from the margins. It moves freely in the water by a combination of passive drifting and Learn about different types are organisms that live in the ocean. Design their own creature using the information they have gained about various adaptations and why organisms use them. Materials contractions of its bell-shaped body. Polyps, such as coral, sea anemones and hydra, are tubular-shaped with tentacles on top around the mouth. They are sessile and frequently form Learn about different types are organisms that live in the ocean. Design their own creature using the information they have gained about various adaptations and why organisms use them. Materials colonies. Medusae reproduce sexually, whereas most polyps reproduce by budding asexually. Most Cnidarians are marine species.

^ Day 2:

Part 1 - Post movie question for teacher facilitated class discussion:

1) Why do you think that as you descend down to Learn about different types are organisms that live in the ocean. Design their own creature using the information they have gained about various adaptations and why organisms use them. Materials the bottom of the ocean, do you see smaller animals like worms, crabs, etc?

Design their own creature using the information they have gained about various adaptations and why organisms use them. Materials their body requirement. Most large animals on the ocean floor are scavengers because there is not enough food to sustain them otherwise.

2) Have your student discuss their favorite deep sea fish Learn about different types are organisms that live in the ocean. Design their own creature using the information they have gained about various adaptations and why organisms use them. Materials or invertebrate that they learned about.

4) What is the impact of scientists finding two habitats in the ocean (the deep sea trenches and the lake in the Gulf of Mexico) that are Learn about different types are organisms that live in the ocean. Design their own creature using the information they have gained about various adaptations and why organisms use them. Materials not dependent on sunlight for energy? Allows scientists to understand how life may have evolved before plants evolved the ability to photosynthesize. Found animals dependent on bacteria for food and oppose to sunlight Learn about different types are organisms that live in the ocean. Design their own creature using the information they have gained about various adaptations and why organisms use them. Materials. Furthermore, since our atmosphere began with high levels of methane and sulfuric acid, it showed how organisms use to live before our atmosphere changed to its more oxygenic state that it Learn about different types are organisms that live in the ocean. Design their own creature using the information they have gained about various adaptations and why organisms use them. Materials is today.

4) Why is it so hard for scientists to explore the deep? As you descend down, the pressure increases dramatically. For every 33 feet down you descend, one more atmosphere (14.7 psi Learn about different types are organisms that live in the ocean. Design their own creature using the information they have gained about various adaptations and why organisms use them. Materials) pushes down on you. For example, at 66 feet under the surface, the pressure equals 44.1 psi, and at 99 feet, the pressure equals 58.8 psi. At the deepest point in the ocean the pressure is more Learn about different types are organisms that live in the ocean. Design their own creature using the information they have gained about various adaptations and why organisms use them. Materials than 8 tons per square inch, or the equivalent of one person trying to support 50 jumbo jets. So if we do not use submersibles like Alvin we will be crushed as we descend down Learn about different types are organisms that live in the ocean. Design their own creature using the information they have gained about various adaptations and why organisms use them. Materials to the bottom of the ocean. That makes exploring a bit more challenging since 71% of the world is covered by ocean and most of that ocean is Deep Ocean where Learn about different types are organisms that live in the ocean. Design their own creature using the information they have gained about various adaptations and why organisms use them. Materials we need submersibles to explore those regions.
