Week of March 6th - March 10th
Adaptations are structures, colorings, and
behaviors that help organisms meet their needs and keep themselves alive.
Structures are parts. For example, many animals have teeth or fangs that help them bite prey. Structures vary depending on the type of organisms. Plants and animals have very different parts but their parts help them stay alive in their environment. Plants may have long deep roots or short shallow roots depending on the amount of water in their environment.
Adaptations are also behaviors. For example, some animals hibernate in the winter as an adaptation for surviving during extremely
cold weather when there isn’t as much food. This is a behavior the keeps them alive.
Getting Food – Look at the pictures on the left. Each organism has adapted to being able to consume food in its environment. What do you think each organism eats based on its mouth structure?
Moving Around - By looking at an animal’s
structural adaptations you can tell how it moves. For example, a duck has wings and webbed feet. Wings make it possible to fly. Webbed feet are good for swimming. So a duck flies and swims. Look at the two types of turtles. How does each turtle move? Where do you think these turtles live?
Body Coloration and Coverings – In cold climates, mammals have longer and thicker fur to stay warm. In hot climates, you find animals with thinner skin and less fur. Organisms use body color as an adaptation to avoid being eaten whether it is bright warning colors, countershading, or camouflage. Bright colors tell predators, “Hey, I will make you sick if you eat me, so stay away!” Other animals have drab colors to help camouflage them with their surroundings so predators cannot
easily find them.
There are many, many more interesting and sometimes strange adaptations that animals use to survive. For more information, check out:
Plants have adaptations to help them survive in different areas. These adaptations might make it very difficult for the plant to survive in a different place. This explains why some plants are only found in one area, but not in another. For example, you wouldn't see a cactus living in the Arctic. Nor would you see lots of really tall trees living in deserts. For more information about plant adaptations check out: http://www.mbgnet.net/bioplants/adapt.html |

Due to district changes in homework policies, I will no longer be passing out weekly homework.
Students will continue to receive study guides for up coming tests and any unfinished
