8th Grade Science Favorites:)

2009-05-06T07:39:00.000-07:00

ASTRONOMY: MY favorite section of Astronomy was the moon! And how it goes through so many phases. Well, depending on how the sun faces the moon depends on the phase. If the sun is facing away from Earth then it will most likely be a new moon. Or if the sun is facing directly toward the Earth then it is probably a full moon. The moon is HUGE! Almost 3500 kilometers. There is no atmosphere as well as no water but some ice patches. The moon theory is that a planet-sized object collided with earth to form the moon. The moon also causes tides in the ocean. If you have ever been to the beach you would know that the water comes up the beach a little bit then goes back into the ocean. That is a small tide caused by the moons gravity pulling. All in all, astronomy was by far my favorite part of earth science for my 8th grade year.
WEATHER&CLIMATE: Weather is a big part to earth. There are many kinds of weather types that are classified into to groups. Softer and Extreme. Softer would be rain or snow and extreme would be tornadoes and hurricanes. Also wind helps determine the weather. It also determines the direction the storm travels. Fronts are also the causes for weather. It is like a fight between warm and cool air fighting for first place which causes tension then eventually leads to s storm. The sun also contributes to the types of weather. If it is sunny it could possibly snow but most likely wouldnt because of the heat radiation of the sun. The weather also tells what season it is. The seasons depend of the rotation of earth on its axis.
GEOLOGY: Earths atmosphere is made up of mostly water. Our atmosphere contains Nitrogen, Oxygen, and Argon. These are gases we brethe in and out every single day. Depending on our atmospheres climate, it is affected by the water vapor CO2, CH4, N2O, and SO2. Our atmosphere is not only consisted of gases it also contains dust, rain, snow, and volcanic ash. Earths atmosphere is very different from other planets. Our planets atmosphere actually contains atmosphere. And it is moist unlike alot of planets. The pressure of the atmosphere depends on the height. Like below sea level and above sea level. Geology was by far the most interesting.
WEATHERING&EROSION: Weathering is the decomposition of earth rocks, soils and their minerals through direct contact with the planet's atmosphere. There are 2 types of weathering: Chemical and Mechanical. Mechanical is a physical change such as the breaking down of rocks. Erosion is the removal of rock by wind, water, ice, or gravity. Weathering and erosion section was the funnest but not my favorite. I loved taking videos and pictures of weathering and erosion in my neighborhood and putting them into an I-movie.
EARTH'S WATERS: Water is yummy:) well it was very fun learning about the process of how we get our water. I didn't know there were that many steps to make good drinking water! There are filtrations, chlorinations, and aerations. These steps give us our delicious glasses of water:) Our water starts in a reservoir! Didn't know that one but thanks to earth science i am educated in many things like stars, and water!

All in all, i loved earth science even though i missed quite a bit of the class because i was sick:( i got caught up and now i know ALOT of aspects of science! :)
Thanks Mrs. Casey!

Where We Get Our Water From

2009-04-30T07:25:00.000-07:00

About 75% of the water we receive comes from mountain springs in the areas of Aspen, Lead ville and Breckenridge – Colorado. Pipes that transfer this water to reservoirs like rampart and catamount are at the least 10.6 miles in distance.Walking time would be about 1 day and 6 hours. Rampart is a 500 surface acre lake between the US Air Force Academy and Woodland Park. Catamount is a 210 surface acre lake on the North slope of Pikes Peak. From the reservoirs, the water is transfered to water treatment plants before it is received in homes. There are 5 local water sources: Pikes Peak Northern and Southern slopes, Cheyenne Creeks, Fountain Creek, Peakview Reservoir in Monument, and Northfield Watershed. Then there are 4 local ground water sources: Arapahoe (4wells), Denver (1well), Laramie-Fox Hills (1 well), and Widefield (4wells). From these treatment plants, the plant distributes the water to the many homes in the city of Colorado Springs and the border to border cities. Such as Manitou Springs, and Breckenridge.

Water Cycle Active Art

2009-04-22T07:31:00.000-07:00

The water cycle is a cycle in which the water moves. The water cycle consists of three steps: Evaporation, Condensation, and Precipitation. Evaporation is when the water is brought up to the sky from water or plants. Condensation is when the moisture from earth forms clouds that carry precipitation. Precipitation is any type of moisture that falls from the sky. Such as, rain, hail and snow. The water cycle begins with Evaporation, then Condensation, then to Precipitation. Imagine a sunny day after a big rain storm, there is a puddle. The moisture in the puddle will evaporate because of the suns radiation then this small puddle of moisture will condense into clouds. The moisture from the clouds will then fall as precipitation as long as its heavy enough. If its not, then it will go back into the clouds. Soon it will be heavy enough to fall as precipitation.

Annotated Bibliography

Energy Star-
http://www.energystar.gov/index.cfm?c=about.ab_index
ENERGY STAR is a joint program of the U.S. Environmental Protection Agency and the U.S. Department of Energy helping us all save money and protect the environment through energy efficient products and practices.

Tree Hugger-
http://www.treehugger.com/files/2009/03/epa-announces-new-energy-requirements-for-monitors-photo-frames.php
Tree hugger gave me information on how energy star is used in monitors, and digital photo frames. So therefore, energy star can be used in almost everything.

Small Business Trends-
http://smallbiztrends.com/2009/04/energy-star-helps-you-save-money-and-go-green.html
This website mainly describes how you can save money by using less energy, specifically by Energy Star. It can help you save money by bills, and being able to save money rather than use it on energy bills.

Weatherization-
http://www.waptac.org/sp.asp?mc=techaids_estar
This website talks about how these two partnerships came together to help the production of Energy Star. This helped produce many more appliances like washers.

Essential Questions.

2009-04-16T07:21:00.000-07:00

Q:What, specifically about your topic, are you going to research?
A: When researching our topic, I will specifically research the many uses of Energy Star and how exactly it helps earth.
Q: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.
A:People use Energy Star for many appliances. Such as dishwashers, washers, dryers, and furnaces. It helps earth by saving energy in households, manufactures, and warehouses. I feel that average citizens should take in the idea of using Energy Star, not only to help the earth but to also help bills. Energy Star can save families a third of there energy bills just from using a brand of appliances.
Q:What would happen if, worst-case scenario, nobody listened to your recommendations?
A:If people dont listen to my recommendation then we could be going on energy overload. It not only waste resources but it effects the health of our planet. Using less energy leads to less power plants and decreased pollution.
Q:What would happen if, best-case scenario, everybody listened to your recommendations?
A: Our planet would have less pollution, which helps humans, animals, and the environment around you. Using energy isn't bad but using to much could lead to bad things.

Penny lab-Waters Properties

2009-04-14T13:56:00.000-07:00

I did this penny lab by first collecting the materials of a penny, a cup of water, and a water dropper. I layed the penny on a paper towel then applied droplets of water from the water dropper on the penny and recorded how many drops it took for the water to overflow over the penny. I predicted it would take 3 drops of water but i was way off! I soon discovered it took 12 drops of water for the overflowing to occur. this happened because all the water molecules stick together and create an even bigger molecule which causes it to overflow.

Earthquake Websearch

2009-01-22T08:00:00.000-08:00

Question 1: Where do most earthquakes happen?
a1: Well earthquakes are caused by the collision of the earths plates. Mostly occur on the pacific coast but can also occur anywhere.

Question 2: Why do you think that is?
a1: I think this is because the plates that collide are colliding under the ocean. Which means that when an earthquake has occured the plates under the ocean or above like the one in Iceland, have collided.

Question 3: What is that area called?
a1: The area is called The Ring of Fire which is located around the Pacific ocean.

Question 4: Where is the earthquake closest to Manitou Springs?
a1: The earthquake closest to Manitou Springs is in Denver and people in Manitou would not be able to feel it because of the distance and the magnitude. A magnitude 1 is to weak to feel while a magnitude of 5 would be mush more strong to the point where we might be able to feel it.

Question 5: Choose one earthquake that has happened in the last seven days.Are earthquakes common in this area?
a1: The earthquake i chose is an earthquake of 5.0 magnitude and has happened at 11:23 am (mountain standard) on January 14. This earthquake accurately occured at 31.210°N, 103.427°E. It occured on the eastern border of Sichuan, China. The depth of this earthquake was about 25.9 km (16.1 miles). .

Question 6: How can people protect themselves from the dangers of earthquakes?
a1: In an earthquake you must stay safe or sad consequences could happen. Like Any bookcase type piece of furniture that might topple over during an earthquake should be secured to a wall, A meeting place for your family, outside the home, should be identified. and also standing in a door way would be a very safe place to sit/ stand during a doorway=]

Fronts

2008-12-05T07:47:00.001-08:00

Cold Front:The cold front runs into the warm air and causes it to go over the cold front.... causing thunderstorms!
Warm Front:the warm front comes, and runs into the cold front.... causing cloudy skies and rain!
Stationary Front:The warm front and cold front collide, forcing each other in opposite directions.... causing major thunderstorms!
Occluded Front:The cold front on the left and the right collide causing the warm air in the middle rise above the cold fronts causing thunderstorms!
Which type of front occurred this week to bring the cold weather and then snow?: The type of front that came causing cold weather and snow was a cold front!

London Type Smog

2008-11-04T07:37:00.000-08:00

Too start out with, Smog comes from the words smoke and fog. Which come together as smog. On December 4th, 1952, due to and caused by air pollution of coal, emission of Sulphur dioxide, and dust. The London Type smog occurs when a water droplet in the air condenses on smoke particles produced by the burning of coal. Forming tiny smog droplets. Sometimes called sulfur smog.
There were many deaths due to this smog. Yet,there was many more diseases, such as: Pneumonia, Bronchitis, Tuberculosis, Heart Failure, Asthma, Respiratory Distress, Cardiac Distress, and Asphyxiation. There weren't many solutions to prevent these diseases from happening except for wearing gas masks.

Earth's Atmosphere

2008-10-29T07:16:00.000-07:00

Our solar system is very unique and different in many ways. Our atmosphere contains Nitrogen, Oxygen, and Argon. These components affect other things in the atmosphere, like the water vapor. Our climate is affected by the water vapor CO2, CH4, N2O, and SO2. But though the greenhouse effect is sometimes thought as a bad thing. Yet, trace amounts of gases warm our atmosphere enough to sustain life.
But our atmosphere doesn't only contain gases, it also contains particles of dust, rain, snow, and volcanic ash. Geologists say, back then, there was no free oxygen. Then when Photosynthesizing bacteria evolved, the oxygen steadily rose from 0%, 2 billion years ago to 21% today.
The pressure of the atmosphere varies different heights, like at sea level it would be 960 to 1050 millibars and on top of Mt. Everest. it would most likely be about 300 millibars.

Summaries

2008-10-05T14:23:00.000-07:00

The Science Of Rockets
Nasa used Atlas Rockets to launch probes into space. The rockets are 58 meters high, They have 3 stages. The Atlas which uses bith solid-fuel boosters and liquid-fuel engines. The Centaur that uses liquid-fuel engines to maneuver into proper orbit. And The Payload which is satellite or spacecraft carried by a rocket.
The Space Program
Nasa had many projects to land on the moon. But one, Apollo 13 was the most extreme. Apollo 13 was lauched on April 11, 1970. It was at first, the smoothest flight but everything changed. 2 days into the flight, an oxygen tank blew up, which was a huge disaster in this case. Also, the command module(CM) supply of eectricity, light, and water was lost, The crew finally found a way to remove the carbon dioxide from the rocket using materials from the rocket. And they finally landed in the pacific ocean near Samoa.
Exploring Space Today
Nasa conducted a robot called a "Personal Satellite Assistant". This was a robot that had all sorts of technology that would help Nasa. This robot would float next to an astronaut in space and tell them information such as the temperature, pressure, and air quality.
Using Space Science On Earth
Nasa wanted money invested to the space program and every dollar invested, the U.S economy would recieve a $7 return in the form of job creation,economic growth, and taxes. But many people argued that the money could be used formore useful things, such asmedical care.

Wimalling(Winter,summer,fall,and spring)

2008-09-21T18:11:00.000-07:00

Seasons are all different. For instance, theres winter which is cold. Fall which is breezy and chilly. Spring is when the flowers bloom which is rainy and summer is SUPER hot. But why is this? We have these beautiful seasons because the earths axis is tilted as it revolves around the sun. Without these seasons, what do you think the world would be like?

Perspective Paragraph

2008-09-14T09:18:00.000-07:00

The book Zoom by Istvan Banyai is a perspective test for your mind and eyes. This book was a book that was focused on one tiny zoomed picture then when zoomed out it becomes different things such as, magazines or brochures. "Seeing depends on knowledge and knowledge, of course on your college. But when you are erudite and wise, what matters is, to use your eyes." by Ernst Bombrich. This quote states that knowledge is very important in many ways. Perspective is the science of painting and drawing so that objects represented have apparent depth and distance.
Have you ever thought you were looking at something right but it was really wrong? Well, many people do it all the time without even knowing it. An example of this would be like if your looking at a hill from far away and then the closer you got it turned into a mountain. Sometimes when i see something wrong i try to blur my vision and fix it. Like the example of the hill and the mountain, i blurred the picture in my mind and fixed it.
Many people might be interested in this data because many people use perspective everyday. Perspective is used in many wasy because when you expect something it might not be what you expected. Especially, in Astronomy! Astronomy uses perspective to point out many different groups of stars. Like the way someone pointed out the leo or the dippers. They used their perspective to group things together to make one picture!

How to add music

2008-09-09T14:40:00.000-07:00

The Quick Answer
Choose whether to embed audio/music from a third-party site or to host your own (podcast).
To podcast, choose a host to store your audio files, then enable 'Link Fields' in your Settings Formatting tab.
Use the link field to enclose audio files in your posts.
If you'd like to put music or audio on your blog, there are many options available to you. First you'll have to decide whether you want to host your own audio files or merely embed them from an existing third-party site.
Embedding music/audio from third-party sites
If you'd like to embed a playlist or functionality from a third-party music service such as Last.fm or Imeem, Blogger's layouts feature makes it easy.
Visit your Template Page Elements tab.
Create a new widget by clicking "Add a Page Element."
Choose the "HTML/Javascript" widget.
Enter the HTML code provided by your third-party music service into the content window and click "Save Changes."
If you can't find the necessary code, you may have to contact your third-party music service. Feel free to position the page element wherever you'd like.
There are plenty of services to share and embed music available on the web. Here's a list of a few to get you started. Please keep in mind that these services aren't affiliated with Blogger, but we've heard good things about them.
Last.fm

MyFlashFetish
Podcasting
If you'd like a way to distribute ongoing recordings of your own, you may be interested in using your existing Blogger feed to create a podcast. Podcasts can be used for a variety of purposes, such as syndicating your own weekly internet talk show or mixtapes. They work by using your blog's existing feed to link to audio files you have hosted on the web. RSS Readers (such as Google Reader or Bloglines) then interpret your links as embedded audio files and provide an interface to play them. Note that your audio files will still be available directly on the blog, too. To get started, you'll need a place online to store your recordings. Blogger doesn't offer hosting services for audio files at this time; however, there are plenty of providers of online storage space that offer both paid and free hosting services, such as Box.net, MoveDigital, DreamHost, and BlueHost. Once you've uploaded your files to your web host of choice, you'll need to enable enclosure links to link to the file from within a Blogger post. To do so, just go to your Settings Formatting tab and set the "Show Link fields" option to "Yes." This will add the enclosure link fields to your post editor. When composing a post, you'll then see a field for your enclosures. From there, just enter the URLs of your audio files, and your blog will instantly become a podcast. When viewed with most RSS readers or podcatchers (such as Google Reader, iTunes, or Bloglines), your recordings will appear as embedded music players. It's that easy!
If you'd like to further customize your podcast, you may be interested in checking out FeedBurner. By processing and optimizing your existing Blogger feed, FeedBurner not only offers extensive podcasting options but also the ability to customize, optimize, and monetize your feed and to track the number of listeners subscribed to your podcast.

The Enigma Box!

2008-08-29T07:31:00.000-07:00

The Enigma Box is a box that you fill with water, but there is a way that it comes out that is untold. First, the Enigma box consists of water pressure and air. Have you ever put your finger over the top of a straw and bring it out to drink? Have you noticed that the air isn't getting into the straw so the drink doesn't come out? Well, when you let go it flows out very quickly. That is exactly how the Enigma Box works.
The Enigma Box is rectangular shaped with 2 holes with that are different sizes and it holds the water. As the Enigma box receives more water it begins to leak. So the more water that is put into the Enigma box, the faster the water flows.
Also, the Enigma Box is a box that holds a liquid and you fill it up with the liquid and you start off with a small amount, then you fill with a larger amount and at about 450ml. is when it starts flowing really fast. All the water filling the Enigma Box finally reaches a point then it flows out.
To end with, the Enigma Box is a box that you use all 5 senses, and the 5 skills to observe. Inferring, Predicting, Classifying, Observing, and Making Models are the 5 skills that scientists and normal people use everyday to observe or examine something. The Enigma Box has a tube that loops around inside and when the water fills to a certain level then the water flows over the loop and out of the box.
