Bats are mammals.
Bats have body adaptations to survive in their habitats.
Microbats are small on average, eat insects, migrate, and live in temperate zones.
Megabats are larger than microbats, eat fruit, and live in tropical zones.
People are destroying bat habitats by farming, building, and logging.
People can protect bats by saving their habitats and educationg others.
Bats help the earth by pollinating plants, eating harmful insects, and providing a natural fertilizer.

What is a map?
How are maps created?
How are maps helpful?
How do you use a compass rose?
How do you use a map key?

A map is a drawing or other representation, usually on a flat surface, of all or part of a celestial body's surface, ordinarily showing bodies of water, land surfacels, roads, etc.
Maps are tools people use to learn information, especially geographical information.
Topical and political maps are created by surveying a celestial body's geographical features, preferable using a 'bird's-eye-view', and then drawing those features accurately onto paper or other similar medium.
Maps help people find their way, learn information about the geographical features of places, or locate those geographical features.
A compass rose is an instrument for showing direction on a map.
A map key explains the features of a map.

Draw an imaginary island. Then create a 3-D representation of the drawing.
Draw a map of the island from a 'bird's eye view'.
Put a compass rose and a map key on the map of the island.
Play a directional game.

The finished product - an accurate map of an island, including a map key and a compass rose.

Oregon Tide Pools

What is a tide pool?
How are the four tide pool zones different and how are they the same?
What is the difference between tropical tide pools and temperate tide pools?
How do tide pool creatures adapt to their environment?
What adaptations do tide pool creatures have to survive?
What is a 'food chain' and how can it be disrupted?
How can people protect the tide pools?

The part of the seashore that the tides cover and uncover is called the intertidal zone.
The low intertidal zone is always full of ocean water. The mid intertidal zone is under water except during low tides. The high intertidal zone is only under water at high tide. The spray zone gets wet at high tide but is not under water. Each tide pool zone supports different kinds of life.
Oregon's tide pools are in the temperate zone, where the water is cold, so different life is found there than in a warm tropical tide pool.
Tide pool creatures have body parts that are suited for the tide pool zones they live in.
There is a web of life, or a food chain, in the tide pools, which benefits all the life found there. Different creatures eat each other in the food chain, so if one creature becomes extinct, the whole food chain is affected.
People can protect the tide pool zones by staying away from them.

Watch videos about the temperate tide pool zones.
Create a mural showing the tide pool zones and what creatures survive in each zone.
Do activities and play games to learn about different types of animals found in the tide pools and how the food chain works in each tide pool zone.
Use books and the Internet to research the life of a tide pool creature. Write a report.
Create a diorama of your tide pool creature in its natural habitat.
