Water cycle
The water cycle is the continuous process in which water moves through the environment. The sun is the source of energy that drives the water cycle. the water cycle has no beginning or end. In the water cycle water evaporates from a water source then the precipitation builds up in clouds and when it gets to heavy the clouds release the precipitation in the form of snow, rain, and hail. Then the precipitation falls on the ground and creates runoff and ground water. Now the cycle repeats

Annotated Bibliography
Solar development
http://www.solardev.com/SEIA-sunshinehomes.php
- I found a lot out at this website but the main thing I found here was how solar energy can be used in homes. This site is very good for finding this out because it had a lot of detail in each way Solar energy could be used in homes. I used this website in my presentation to tell ways how solar energy could be used in homes. I found out the info at this site was very helpful to my presentation
Solar Power
http://www.otherpower.com/otherpower_solar.html
-I found a lot at this website about how solar panels worked but i only used a little of the information i found. I found that solar panels have to be big to collect rays from the sun because the suns rays are not very concentrated. I put this information in my presentation some information that did not put on my presentation but that I found was that the solar panels have to be very black in color to collect the suns rays. With this info i explained a little about solar panels in my presentation.
How Stuff Works

-At this website I also found how solar energy can be used in homes. For example at the other site it did not tell solar energy could be used heating pools. Also at this site they told a lot on how solar energy heats water. I used the the info on solar power heating water in my presentation.

-At this website I found out about passive solar energy and and active solar energy and the difference between the two. I used this info on my third and final blog. This site was a great site to find this information. I recommend this site to everyone who wants to find this info.

Group 13 esential questions
1.What, specifically about your topic, are you going to research?.
How can solar energy be used in homes.
2.What conclusions did you come to? What do you recommend average citizens do to make a difference? Be specific. This is the main part of your assignment.
Solar energy is mostly used in homes right now. Some people install solar panels on there roof. The solar panels have to be large to collect energy from the sun because the sun does not shine a constant light on one place.You can live in city and have a solar home. Solar heat energy is often used for heating swimming pools, heating water used in homes, and space heating of buildings. Solar space heating systems can be classified as passive or active. Passive is when in buildings, the air is circulated past a solar heat surface and through the building by convection. No mechanical equipment is needed for passive solar heating. Active heating systems require a collector to absorb and collect solar radiation. Fans or pumps are used to circulate the heated air or heat absorbing fluid. Active systems often include some type of energy storage system.
3.What would happen if, worst-case scenario, nobody listened to your recommendations?
If we keep using coal and natural gas to heat and not solar power we will destroy are ozone.
4.What would happen if, best-case scenario, everybody listened to your recommendations?
We will not destroy the ozone and we will restore it and people will not will not have to pat a lot for energy.

Pennie
I estimated the pennie would hold about 5 drops of water. Therfor I was suprised when the pennie held 15 drops of water. The pennie held this much water because water has a high surface tension. Because of this water can climb up roots and other things. But in this case the waters high surface tension helps the water hang onto the pennie.
