Cold Front-is when the cold air pushes the warm air out

Warm Front-is when the warm air pushes the colder air out

Stationary Front-is when cold air and warm air run in to gether but none of them have the power 2 force the other one out

Occluded Front-is when warm air gets stuck between 2 different kinds of cold air

Green House gas

Green house gas is a gas that makes sure the earths temp is OK for all the living things on earth.A scientist could be the one to study this Green house gas because he/she should know why the gas just makes the temp enough for us to handle and why the gas doesn't get so bad that it could kill us.They should also study if the green house gas will ever get out of control.

Acid Rain

The issue is that Acid Rain is getting in to the lakes and rivers.The cause is that nitrogen oxides and sulfur oxides are combing with the water vapor and making Acid Rain.Some consequentness is that the acid is killing plants and animals and getting in to the rivers and lakes.

Earths Atmosphere

The earths atmosphere is way different from any other planet.One thing is that because of the earths atmosphere we have seasons.Another thing is that are earth is the only planet that can support life.Also the chemicals that we have on the earth help and destroy are planet.another interesting thing is if a metered comes to earth are atmosphere will blow it up but on any other planet the metered will smash in to it and leave a mark,if a metered hits earth the mark will change after time.

Space ShuttCarries crew into space Reused Allows astronauts to fix things Space Station

large artificial satellite


people live and work on for long periods


 


The role of space shuttle


 


 go in to space and fix any thing that is broken


  The role of space station       to have people live and work for long periods of time   Space probe     spacecraft   scientific instrument that collect data   collect visual data with no life on bored 3 things that all space probes have each have power system to produce electricity


communication system to send and receive signals


scientific instrument to collect data and perform experiments


Advantages is that people dont have to risk there life by going up into space but if it brakes then they have to go up there ne ways and fix it

Space Exploration

The Science of Rockets

There are 3 stages.The first is called Atlas,witch uses soiled-fuel boosters and liquid-fuel engines to launch.The second stage is called Centaur,witch only uses liquid-fuel.The third stage is the Payload-the satellite or spacecraft that falls to earth and burns.

The Space Program

NASA is the National Aeronautics and Space Administration.There the people who came up with missions for the astronauts to do.Like project Mercury,where they tested if people could live in space.Apollo 13 is an air craft tested to see how it would work,it didn't turn out that good.

Exploring Space Today

The iss came up with little robots powered by solar cells.They go up with the astronauts and fly right next to them,using fans that control the way they move.

Using Space Science on Earth

NASA isn't getting enough money to build more stuff.they wont money so they can explore the unknown.Many people argue that the money can be spent better like for education or medical research.

Gizmo

Well many things cause the seasons.The movement of the earth,the sun and solar energy.When there is more sun and more solar energy on the earth the hotter it will be.The less sun and solar energy on the earth the colder it will be.Are earth moves all the time,and the more it moves the more or less sun and solar energy we will get.so when there is alot of sun light and solar energy,that means that it will be a warm seasons.When there is not so much sun light and solar energy,that means that it's gana be a cold season.

Zoom

Zoom is a book by Istven Banyai.The book is just a hole bunch of pictures.There is no words.The first picture looks like a fire but its rilly a rosters head.The book keeps doing that over and over agen.It will show you a picture,then it will zoom out and the picture will be something totally different.

Well basically this book is telling u how far it zoomed out ,without saying anything.This book is like the movie Power Of Ten.the move zooms out then tells how far it zoomed out.The book doesn't say how far it zoomed out but you can tell when u see the picture.There would be alot of scientist interested in the info I'm giving because any kind of scientist could us the power of ten.

My perspective changed Meany times threw out the book.The first picture,i thought was a fire but it turned out to be the top of a chickens head.When i first saw the picture i was sure it was a fire and i couldn't think of any thing els it could be,but then the picture zoomed out and my perspective changed.Every time i saw a picture ,i just thought it to be one thing and i couldn't aceppted it to be any thing els .lets just say my perspective wouldn't change until i saw the other picture,but all in all it was a good book

Enigma Box

I observed that there was 2 holes in the box (one on top & the other on the side).The watter got pored in slowly & the more watter in there the faster it came out.The box was half full when little drops came out.When all the watter was in the box it came out rilly fast & all of the watter came out.Well since there was 2 holes i thought it may have some thing to do with air bubbles,like when u blow in to a watter bottle the watter comes out faster & stronger.Or it may have something 2 do with pressure or here may have been a little flap & there was to much watter.well that may not be right but its what i observed.

Scientist use many skills to find the answers they need.well i used some of those skills 4 this project,like predictions,observe,hypothesis & inferring. I used inferring by knowing water always runs down hill & that presser can make water come out. To help solve my problem,first are teacher showed us that she can poor watter into the enigma box & nothing will come out until all the watter was in.I guess that it had something to do with presser.She showed us how it rilly worked,i was wrong.The way it works is by watter going in a tube then out.....awesome.
