Program Sea Monsters: A Prehistoric Adventure

Directions

1. Build background about habitats.
Write this definition of habitat on the board: “the place or environment where a plant or animal naturally or normally lives and grows.” Ask students to brainstorm things that make up a habitat, such as water, air, trees, rain, snow, and sand. Explain to students that Earth has many habitats and that each type of habitat is unique. Provide examples of habitats, such as oceans, forests, deserts, tundra, rivers, lakes, and wetlands. Tell students that even under water, there can be habitats such as shallow-water or deep-water zones, and that a combination of many things—including temperature, soil, available food, rainfall, and geographic location—create a habitat.

2. Have students brainstorm basic survival needs.

Ask students to brainstorm four basic survival needs that all animals require from their habitat. Prompt students to think about things that are essential for survival. Elicit from students that four basic survival needs include:

  • food
  • shelter from weather and predators
  • water
  • a place to raise young

 

3. Use a think aloud to provide an example for students.
Think aloud as you provide the following example for students:
Animal: salt water crocodile
Habitat: coastal marshes, estuaries, and shallow marine waters

This animal's basic survival needs include:

  • food—carnivorous (eats meat), including fish, birds, reptiles, and mammals
  • shelter from weather and predators—have camouflage and can submerge for long periods of time
  • water—provided by diet and from freshwater sources
  • a place to raise young—female prepares and guards a nest until the young hatch and are released

 

4. Have students brainstorm additional examples.
Ask the class to brainstorm other examples using animals they are familiar with, such as dogs, cats, hamsters, birds, or horses. For each example, discuss the animal’s habitat and basic survival needs. Continue until students have grasped the concept.

Extending the Learning

For an increased challenge, have students brainstorm the basic survival needs of animals from a variety of habitats, such as the jungle, Arctic, desert, or Alpine regions.
