What are 4 energy concerns? In this section we examine some problems associated with the use of fossil fuels, fuel wood, uranium, hydro power plants and wind energy….Global warming Rise in mean (average) global temperature. Rising sea levels. Occurrence of weather extremes. Shifting of vegetative zones. What is the world’s energy problem? The energy problem […]
How is air pressure usually measured?
How is air pressure usually measured? A barometer is a scientific instrument used to measure atmospheric pressure, also called barometric pressure. The atmosphere is the layers of air wrapped around the Earth. That air has a weight and presses against everything it touches as gravity pulls it to Earth. Barometers measure this pressure. What time […]
What do most plants need to grow?
What do most plants need to grow? Plants, like all living organisms, have basic needs: a source of nutrition (food), water, space in which to live, air, and optimal temperatures in order to grow and reproduce. For most plants, these needs are summarized as light, air, water, and nutrients (known by the acronym LAWN). How […]

Why do pots boil over?
Why do pots boil over? With the combined influences of heat and water, the starch thickens as it rises to the surface, creating an active agent at the top of the water which blocks air from escaping. Because it contains more air, the volume of water then expands, rising to the point of boiling over. […]

What forms of energy changes take place when a gun is fired?
What forms of energy changes take place when a gun is fired? A bullet stores chemical potential energy in its gunpowder. When the bullet is fired, this chemical energy is converted into kinetic energy and heat. Why does the Dart have a little bit of gravitational potential energy before it is fired? However, the dart […]
Is gravity created by mass?
Is gravity created by mass? So, the closer objects are to each other, the stronger their gravitational pull is. Earth’s gravity comes from all its mass. All its mass makes a combined gravitational pull on all the mass in your body. That’s what gives you weight. Does rotation affect gravity? While the spinning of the […]
