Kepler’s third law is all about the timing of the planets’ orbits. It states, “the ratio between the square of the time needed by a planet to make a revolution around the sun and the cube of its average distance from the sun is the same for all planets.” This law can be expressed in the following formula:
(Period of planet)^2/(Average orbit radius)^3 = Same result for all planets.

You can use this formula to collect data for your entry into a science fair competition

Kepler introduced multiple theories that related to the movement of the planets. His second law was that “a planet moves so that its radius vector sweeps out equal areas in equal times.”

You can use this information to create an astronomy science fair project for a science fair competition

Students working on astronomy science fair projects can benefit from learning the basic theories behind the science of astronomy like Kepler’s first law. This law state is based on the assumption that planetary orbits are ellipses and that the sun provides one of the elliptical foci.

When we gaze at the night sky do you believe that you are looking at the universe as it exists?

Actually, many of the photons that you are seeing have traveled for billions of years to get here and the stars that produce that light have already left for other destinations.

Because of this phenomenon… the vast distances between us and the stars and the changing configuration of the universe… it is diffcult for us to know exactly the true nature of the celestial world.

The one thing that has been figured out is tht the universe is 13.7 billion years and and is continually expanding.

When you are faced with your very first science fair project or your fifth science fair project assignment your reaction most likely will be the same…Yikes! However, a science fair contest doesn’t have to be scary or overwhelming.

The first thing that you can do to make your science fair project experience less intimidating is to focus on a topic that is interesting to you. For example, if you enjoy star gazing or science fiction related to space travel, then consider focusing on astronomy. This field of science has a lot to offer students working on science fair projects.

Within the subject of astronomy are volumes of possible science fair project topics. You can look at stars, galaxies, gravity, black holes, worm holes, super novas, the Big Bang Theory and even the speed of light. Each of these topics have dozens of possible sub topics and topic options.

Once you have a topic that looks interesting you need to find a unique angle or approach to that topic that will allow you to create a science fair project. This focusing of your topic step by step is the best approach.

A recent study that used NASA’s Spitzer Space Telescope discovered that a significant percentage of nearby sun-like stars have dust clouds that orbit them. This means that the building materials for Earth-like planets are present and this increases the chances that such a planet may be developing or may have already developed. According to the findings of this study, there should be Earth-like planets in between 10 and 62 percent of the sun-like star orbits.

If you are planning a solar system unit, then it is important that you supplement your discussions with new findings like the ones mentioned in this posting. The problem with using text books to teach evolutionary classes like science, is that by the time the text has been written, edited, published and distributed, the information is already out-of-date. That is why you need to supplement text books with current science events, news articles and findings.

Science news blurbs can be great sources for outstanding science fair project ideas in addition to in class science projects and demonstrations. For help finding science news summaries and ideas about designing and developing science fair projects, return to this blog each Friday.
