Natural+Science

toc Hooraaayyyy! Home of Elena and Roberta...here to meet all of your Natural Science needs! Welcome to the amazing world of science! =Minerals and Rocks=

Links
[|Minerals at Home] This page shows where we use minerals around the house. [|Identifying Minerals] This video is a little advanced, but worth a look. At the beginning, he speaks about the difference between rocks and minerals, then goes into how to identify minerals using their properties, with specific examples. Review this before the laboratory and again before the test to make sure you understand the properties and what they look like! =Atmosphere and Weather=

Layers of the atmosphere Check out this link for another look at the layers of the atmosphere. Quiz yourself and see if you know what objects will be in each layer, or what the temperature will be! Notice that you can click on the different layers to see more information. Check the box labeled "pressure". Why do you think the line looks like it does? What do you think pressure is? =Light and our Planet=

[|Seasons Interactive] Move the Earth through the year. Try clicking to show the equator and the tropics. Pay attention to what angle of light is coming to each hemisphere. [|Seasons Game] How well do you know when and where the seasons occur?

[|The Moon] Learn more about the phases of the moon and the eclipses. Make sure you check out the animation on the second page about the lunar cycle. Note: When they talk about Lunar Eclipses, they show a partial eclipse of the Moon. We only talked about a complete lunar eclipse, when you can't see the Moon at all. =Solar System= =Documents=

News
Check out the discussion page for Natural Science. We've added a place for you to ask questions about the Solar System or answer questions your classmates have asked. =Animals=

Videos
Hi students, here comes a video about marine invertebrates. Can you say the types of animals in the video??media type="youtube" key="vO_rLzwjevQ" height="390" width="480"

This video shows a little (very little) animal, it is a tardigrade, oso de agua o tardígrado in spanish. How big is it? Where does he live? media type="youtube" key="um79Ddw4m4A" height="390" width="480"

Exam Prep
Hi students! We will have an __exam__ about animals. You have to be able to explain the adaptations of the different groups. To do this you have to think about the common features and the three vital functions (nutrition, reproduction and interaction).
 * An example**: Poriphera are adapted to live in water because they don't have sistems and the cells of the colony must be in contact with the water. Sponges don't have skin in order to make the cells be surrounded by water. Water conteins oxigen and other nutrients and the cells take them from water.
 * Question**: What about amphibians, do they have systems? How are they adapted? To which tipe of environment?

Here you have a model of pre-exam. Try it and send it to me to: elenapozopascual@yahoo.es

Could you build a time line of the animal evolution? See the social studies page!!!!
