Earth Science Projects
How hot is the Sun? Why do planets spin? What’s a black hole in space? What are Saturn’s rings made of? What keeps the Moon in orbit around the Earth? Now you can discover the answers to these and other fascinating questions about basic astronomy. In Astronomy for Every Kid you’ll learn about the constellations […]
Gravity vs. Mass
The difference in the mass of objects determines which will win in a gravity tug-of-war between them. The mass of Earth is 5.97 x 1024 kg.
Clouds: Man-Made
There are many types of clouds in the sky, some are even man-made, such as the clouds left by airplanes as they fly by. The name of these man-made clouds is contrail (short for “condensation trail”). Contrails are vaporized water that condenses. Condensation is a process by which water vapor is cooled resulting in the […]
Energy: Atmosphere Model
A model represents something. For example, a model airplane is a replica of some real airplane, but much smaller. A model can also represent how something behaves, such as a closed jar represents how Earth’s atmosphere keeps Earth warm. This is done because the atmosphere, a blanket of air that surrounds Earth, traps heat leaving […]
Displacement
Kids get in trouble for “bird walking,” which means to start thinking about other stuff instead of the teacher’s topic. As a kid, I was very guilty of this. But, I was bad about doing it when I taught and have a hard time with this as a writer. For example, I was studying about […]
Air Pressure:Elevation
I love driving around in Colorado. It is such a beautiful state. One summer during our drive we heard a very loud pop. It didn’t sound like a blown tire and I still had control of the car. So what blew up. I stopped the car and my husband checked all the tires. No problem […]
Earth Science: Atmosphere
Question: What is the atmosphere? Answer: The “blanket” of air that surrounds the Earth is called Earth’s atmosphere. Question: Where in the atmosphere is greatest concentration of air? Answer: The layer of air next to Earth’s surface is where Earth’s weather, including clouds occurs.This bottom layer of the atmosphere has the greatest density of air. […]
Acid Rain: Man Made
Sulfur oxides are gases released when fossil fuels (coal and oil) are burned. Large amounts are released when industries and power plants burn fossil fuels.The diagram shows two sulfur oxides: sulfur dioxide sulfur trioxide The main source of nitrogen oxides is from the exhaust of vehicles. Nitrogen oxides and sulfur oxides in air react with […]
Space: International Space Station
I received an email with a link to how the international space station is being built piece by piece. WOW!! It is so big and is still growing. See for yourself at: International Space Station NASA has many opportunities to learn more about the International Space Station, such as an interactive computer game that allows […]
