Janice VanCleave's Play and Learn About Science
The Animation represents two celestial bodies of unequal masses orbiting around a common barycenter. The barycenter is the center of mass of the two bodies. If the bodies had a connecting rod between them, the center of mass would be where the bodies could be balanced. Animation The animation represents two celestial bodies of different [...]
The barycenter is the center of mass of a system. The barycenter of celestial bodies is a place in space which the bodies orbit. Center of Mass: The mean (average) location of all the mass of the system. Point where a rigid system can be balanced. Discover for Yourself Where is the barycenter of two [...]
Sorry for all the changes to this page. But, when I make changes on any page, it is because I want it to be better. Janice The Earth and the Moon act as if they are connected by a rod. This imaginary rod extends from the center of Earth to the center of the Moon. [...]
Today is the 41st anniversary of the first humans on the Moon. Neil Armstrong and Buzz Aldrin hold the title of being the first to walk on the Moon. There were three crewmen, the third being Michael Collins who orbited in the Command Module while Armstrong and Aldrin were on the Moon’s surface. For details [...]
From Earth, the Moon looks like a round disk in the sky. At times this disk appears to have part of it cut away or is overlapped by something that is dark. The edge or line where the lighted part of the moon disk ends is called the terminator. In the Northern Hemisphere, the terminator [...]
To model the light and dark areas of Earth during equinox, use aluminum foil and a 2-inch (5-cm) Styrofoam ball. With a blackmarker, make two dots opposite each other on the ball. Draw small circles around each dot to represent the Arctic and Antarctic Circles. Again use the marker to draw a circle around the [...]
Overview for an Astronomy Project Your entire project is about a science question you choose to solve. Thus, the project question is very important. The following gives you a “bird’s eye view” of how to select an astronomy question and how to evaluate the question. I. RESEARCH A. “Tinkering” Research or ” I Don’t Know [...]
Astronomy Astronomy is the study of celestial bodies, including the Sun, planets, moons, stars, comets, and asteroids. How to use astronomy facts to develop a science project. Fact: The position of the Sun in the sky during the day affects the length of shadows. Think! 1. There are two things that are changing: the position [...]
A black hole starts out as a star, which is very large. Stars give off light because of the nuclear reaction in its core. This reaction produces massive amount of energy resulting in extreme temperatures. The motion of particles increases with an increase in temperature. The kinetic energy of these particles is in an outward [...]
