The carbon cycle is a process that carbon travels in. There are six reservoirs or places that carbon travels in. G reenhouse gasses like carbon dioxide are dangerous because they are in our atmosphere and are causing the planet to become warmer. In other words, greenhouse gasses create an extra layer (like a blanket) in the atmosphere. This is because humans have burned so much fuel that there is about 30% more carbon dioxide than there was about 150 years ago. On the other hand, without greenhouse gasses, the Earth would be a frozen world. The six reservoirs are soil, the atmosphere, surface water, deep ocean, marine life, and land plants. 5,000 megatons of carbon are released into the atmosphere as fossils fuels are burned each year. When carbon is in the atmosphere, it is added with two oxygen atoms and becomes a greenho

They sound like they are the same thing, but they are completely different. Weather is the conditions during a certain day and time. Climate is the conditions over a long period of time. There are many factors and forms of weather which you have seen or felt before. Humidity Humidity is the amount of water vapor that is in the air. There are three ways that we can measure humidity. There is absolute humidity, relative humidity, and specific humidity. Absolute and specific humidity measure the exact amount of water vapor in the air, but relative humidity measures the amount in the air compared to any other amount. Relative humidity is the most common way that we measure water vapor in the air. Temperature As you may already know, temperature measures the hot or cold that is in the air. There are three scales or ways that we can use to measu

Summary: During this project, I learned about conductors and insulators. A conductor is a material that allows heat (or electricity) to travel through it. Have you ever touched the metal handle on a hot pan, and felt how hot it was? That metal was hot because it allowed heat to easily travel through it. A very important conductor of heat or thermal conductor is metal. An insulator is a material that does not allow heat (or ele

Summary: This week we learned about thermal conductors and insulators and how they are used in everyday life. There are many objects that would be hard to use without thermal conductors and insulators such as frying pans and wooden spoons.  A good conductor is a material that allows heat to travel through it. Have you ever touched the metal handle on a hot pan, and felt how hot it was? A big conductor of heat or thermal conductor is metal. Thermal conductors come in handy when materials that need to conduct heat well such as saucepans. An insulator is a material that does not allow heat to travel through it. As you may have realized, this means that it is the opposite of an insulator. Have you ever seen the material built in homes that looks like cotton candy? This is the insulator for homes, that keeps your home nice and warm. Some other examples of thermal insulators are bubble wrap because the air in the bubbles blocks out other air from coming in, and polystyrene
