Have you ever stood on a scale to see how much you weigh? Weight is a measure of how heavy something is. It is affected by the Earth or any other planet that pulls on objects due to their gravity. The more matter an object has, the stronger gravity will pull on it, and as […]
Have you ever stopped to think about what everything in the universe is made of? Well, everything in the universe is made of something called matter. Matter is anything that takes up space and has mass. That means everything you can touch and see, like your toys, books, and even the air you breathe, is […]
Pulsars are some of the most fascinating objects in the universe. These spinning neutron stars emit intense beams of electromagnetic radiation, which can be detected on Earth as regular pulses of radio waves or light. Neutron stars are the collapsed cores of massive stars that have gone supernova. These stars are incredibly dense, with a […]
A supernova is a powerful explosion that occurs at the end of a star’s life. These explosions are so bright that they can outshine an entire galaxy for a brief period of time, and they are responsible for releasing huge amounts of energy and matter into the universe. There are several different types of supernovae, […]
The seasons are caused by the Earth’s orbit around the sun and the tilt of the Earth’s axis. The Earth orbits, or travels around, the sun in a path that is shaped like an oval. It takes about 365.24 days for the Earth to make one complete orbit around the sun. As the Earth orbits […]
Day and night are caused by the Earth’s rotation on its axis. The Earth rotates, or spins, on an imaginary line that runs through the North Pole and South Pole. It takes about 24 hours for the Earth to make one complete rotation. As the Earth rotates, different parts of the Earth are exposed to […]
Energy can move through substances in the form of waves. Waves are a type of energy that travels through a substance by vibrating the particles of that substance. The energy of the wave travels through the substance, but the particles of the substance do not move forward. Instead, they vibrate back and forth around their […]
Energy is the ability to do work or cause change. It can change from one form to another, but it cannot be created or destroyed. This is known as the law of conservation of energy. One way that energy can change is through energy transformations. Energy transformations are when energy changes from one form to […]
Energy is the ability to do work or cause change. It can move from one place to another in different ways. Here are four ways that energy can move: Heat: Heat is a form of energy that is transferred from one object to another. Heat is transferred by radiation, conduction, and convection. Radiation: Heat can […]
Legend states that gravity was discovered by a man named Issac Newton as an apple fell from a tree and hit him in the head. The more you consider this story though, the less likely it seems to be factual. Did no one understand gravity before Newton? Was he the first person to realize that […]
