The world we live in is really made up of tiny tiny little objects called atoms. They are so small that you can’t see them even if you look through a regular microscope. To see an atom a scientist needs to get a really expensive, gigantic microscope. We won’t need one of those. Why not, you might ask? ... read more

Years ago, your grandmother’s mother had a rag doll. She had probably made it herself from pieces of fabric her mom had given her. The pieces may have been left over from projects her mom had completed. Maybe her mom made her own dresses... read more

Diamagnetism creates a magnetic field in opposition of an externally applied magnetic field. It is always present in earth’s materials in weak ways, although superconductors exhibit a strong effect. Today, scientists have harnessed diamagnetism to create extremely strong water repellants. They call it “the Moses effect.”... read more

Science holds the key to all kinds of hidden mysteries. All you need to do is to learn a few simple rules about it, and you can become a scientific explorer. The great thing about science is that you can actually prove whatever it is you’ve discovered by using it. Science is a way of answering questions like... read more

Physical science is the science of chemistry, physics and astronomy. To discuss just two elementary concepts of physics, I’m going to ask you to keep a little red race car in mind. Then we’ll talk about the solar system. All we’ll do today is define terms, and ask some questions. Physics is the science that deals with... read more

Wildlife Science Projects Key Largo in Florida, USA is home to a very few cotton mice. They have disproportionately big brown eyes for their skinny brown mice bodies. The only place in the world that these tiny beings live is in... read more

Buoyancy is the concept in physics used to explain the forces at work that enable an object to float, basically. These forces are, in essence, the fact that an object seems to lose weight in water. If the volume of water that object displaces is great enough, the object will float. This explains... read more

A ship will float as long as it weighs less than the water it pushes out of the way, or displaces. In order to load a ship with cargo, that ship also has to have air in it. Air doesn't weigh as much as water. This lowers the weight of the ship compared to ... read more
