This resource explains how to calculate the velocity boost needed to inject a Mars spaceship into the transfer orbit, and the arrival velocity at the orbit of Mars. One will be able to tell if the spaceship will be overtaking the planet or be overtaken by it and what the velocity mismatch between ship and planet will be. Full description.

This site describes the planetary swing-by or slingshot effect of boosting the energy of a space vehicle using a close encounter with a planet or other body. The author uses an analogy of a ping-pong ball and paddle to simplify the math involved and goes on to cite several examples of the planetary swing-by, including the Voyager and Pioneer missions. He then explains how these gravity assist maneuvers ... Full description.

This activity has students use simple sine waves to explore constructive and destructive interference in seismic waves. After plotting the summative points of two sine waves, students connect the points to create the resulting complex wave. Once they have successfully drawn their complex wave, they will answer the questions listed on the student handout. Provided are: a list of materials, procedure, ... Full description.

This lesson develops the idea that carbon dating is based on gathering evidence in the present and extrapolating it to the past. Students will use a simple graph to extrapolate data to its starting point. This lesson is the third in a three-part series about the nucleus, isotopes, and radioactive decay. Students will be asked to consider the case of when Frosty the Snowman met his demise (began to ... Full description.

This demonstration is intended to help students better understand the electromagnetic spectrum. At the end of this activity students will be able to explain that energy travels from the sun to the earth by means of electromagnetic waves, and that the shorter the wavelength, the higher the energy per photon. They will understand why shorter wavelengths of electromagnetic energy carry more energy than ... Full description.

This activity demonstrates the presence of ultraviolet (UV) waves. Because the energy from the sun includes not only visible light but also wavelengths longer (infrared) and shorter (ultraviolet) than visible light, it is not always easy to study. Ultra means beyond, so ultraviolet means beyond (actually, shorter than) violet and this demonstration offers a means by which they can be detected. The ... Full description.

At this site students will learn that in addition to making elements, supernovae scatter them. They learn that the elements that are made both inside the star as well as the ones created in the intense heat of the supernova explosion are spread out into the interstellar medium. These are the elements that make up stars, planets and everything on Earth including ourselves. Except for hydrogen and some ... Full description.

This resource describes special properties of light that can help us to understand objects that are millions and billions of light years away. Students explore some of these properties and how they can use them to understand our universe. They will understand that superheated material created by the supernova explosion gives off X-rays and gamma-rays. They will find the answers to questions such as ... Full description.

At this site students are reminded that the study of atoms and their characteristics overlap several different sciences and that chemists, physicists, and astronomers all must understand the microscopic scale at which much of the universe functions in order to see the bigger picture. Students are also reminded of the structure of the atom and the meaning of the terms atom, element, atomic mass, atomic ... Full description.
