Habitats and Changes

In what environment can you find polar bears

The Tundra

Where can you find Dolphins

The Ocean

where can you find camels

The desert

Where can you find Gorillas

In the forest

What organisms are best equipped for surviving in the desert

Camels, Cactus, snakes, scorpions

What does it mean when an organism makes an adaptation to its environment

It has undergone physical change to keep it safe, functional and healthy in its environment. For example, some species of monkeys have long arms to swim from trees while the fins on dolphins have them swim swiftly in the ocean

Name an animal that lives in groups and how that helps them

Wildebeest live in groups or herds with the oldest on the outside to protect the younger and baby wildebeest in case of attack.

In what environment would thick fur be the most helpful

The Tundra

In what environment would you want to be able to store water

The Desert

Where would long and hard claws be the most helpful

when living underground

Where would having a shell as your hiding place or home be the most helpful

on the seashore

List some man-made changes to the environment

A concrete dam stops the flow of water, pollution warms waterways, trees are cut down for housing (In the United States we do a good job of replanting trees after cutting them down)

List some natural environmental changes

A beaver dam causes a pond to form, lightning starts a fire that destroys the forest, a volcano covers an area in lava and ash, a coastal area is flooded from a hurricane or rising sea levels

give the name of a habitat

Ocean

Name an animal that lives in the ocean

Starfish

How does the ocean change

melting glaciers may raise water levels, pollution may lead to increase temperatures or groups of dead spots (toxic areas) of the ocean

How do Sea Stars respond to this change

They get Sea Star wasting syndrome where their arms fall off and they die. So they will try to move and try find cooler climates

Give an example of an ecosystem changing

In certain parts of the artic ice may melt leading to glaciers being further apart

Name an animal and how its traits could help it respond positively to this change

Penguins and their fins would help them swim long distances and adapt better than polar bears for example.

Water is rising on the coast a wall or levee is built to keep water out. What are on positive and one negative impact

The levee will keep animals and organisms safe that would be harmed by a flooded environment. A negative affect is that animals that rely on the coast for aquatic food would no longer have access

Put the description of earth’s 5 rock layers on a list from oldest to youngest

1. A layer that formed before there was life, 2. Fossils of earth’s first life. 3. fossils after the first life on earth. 4. Fossils of life right before humans. 5. Fossils containing the most recent life on earth

Give me examples of fossils

A plant imprint on a rock, a dinosaur tooth, a footprint in a rock slab

You are presented with samples of earth layers oldest to youngest 1. fossils with sea creatures, 2. layer with no fossils, 3. Fossils with dinosaurs. 4. A layer with no fossils. 5. fossils of sea creatures. How would you describe the change over time?

The oldest and youngest habitats in the layers had sea creatures in them. This means that they were both watery areas. The middle habitat contained dinosaurs. This meant that it was a land area. The rock layers show that the habitats went from water, to land, and back to water over time

Bonus name an extinct species and why it went extinct

The Passenger Pigeon and it went extinct due to overhunting

Give examples of remains that are Not fossils

Rat bones on the sidewalk, snakeskin, a seashell at the beach
