Concepts Regarding Electromagnetic Spectrum Electromagnetic (EM) radiation is a form of energy that can travel through space. The different forms of EM radiation make up the electromagnetic spectrum. Light, radio waves, microwaves, and X-rays are all forms of EM radiation. Each form of EM radiation has a certain range of wavelengths and frequencies. All forms travel through space at the same speed, which is 3.0 10 8 meters per second. This value is called the speed of light. Stars and other objects of the universe give off visible light and other forms of EM radiation. The eyes and optical telescopes can detect the light that they give off. Other telescopes have been built to detect radio waves, microwaves, and X-rays from space. To reach Earths surface, EM radiation from space must pass through Earths atmosphere. The atmosphere distorts or blocks some of the radiation. This limits the usefulness of Earth-bound telescopes. Other telescopes, such as the Hubble Space Telescope, are aboard satellites. These telescopes can detect EM radiation from space very clearly. They produce very detailed, highly magnified images of objects in space. Scientists study the data from telescopes. This lets them learn about the distances and physical properties of stars and other components of the universe.

The Reason for the Seasons The reason we have seasons is that, as the Earth revolves around the sun it is closer to the sun in the summertime; therefore, it is warmed in summer and cooler in winter. 1.Why do you think some people have this idea about the reason for the season? 2.What thinks could you do to help someone understand the scientific explanation for seasons? How would this help someone give up his or her original idea in favor of the scientific one? 3.Did you ever have similar Missed Conception at the beginning of this unit or sometime in your life? How and/or why has your thinking changed or not changed? 4.Draw the Earth during all 4 seasons. Label the seasons in the Northern and Southern Hemisphere.

Ballooniverse Purpose: to create a model that illustrates how the universe expands Materials: balloon marker tape measure (or string & ruler) Procedures: 1. Inflate your balloon until it is about 4 inches (10 cm) in diameter, but do not tie the end. 2. Using the marker, make six dots on the balloon in widely scattered locations. Label one dot "home" and the others A-E. The home dot represents the Milky Way galaxy, and the others represent galaxies formed in the early universe. 3. Without letting air out of the balloon, use the tape measure (or string & ruler) to measure the distance from home to each dot. Record the distances in the table under the heading "Measurement 1." 4. Using your tape measure (or string & ruler), determine the circumference of the balloon. Record the circumference in the table under the heading Measurement 1. 5. Inflate the balloon so that its diameter is about 4 inches (10 cm) bigger ( 20 cm). Make a prediction about the new distances from home to dots A-E. Adapted from: http://school.discoveryeducation.com/curriculumcenter/universe/activity2.html

Ballooniverse Conclusion/Questions: Illustrate the changes of your ballon below. 1.How did the distance from the home dot to each of the other galaxies change each time you inflated the balloon? 2. Did the galaxies near home or those farther away appear to move the greatest distance? 3. How could you use this model to simulate the Big Crunch, a time when all the galaxies might collapse in on themselves? Ballooniverse

Wavestown Introduction to the Electromagnetic Spectrum Directions: Use the descriptions below to help locate examples of electromagnetic waves in the Wavestown picture. Radio waves have the longest wavelength in the electromagnetic spectrum. These waves carry the news, ball games, and music you listen to on the radio. They also carry signals to television sets and cellular phones. Microwaves have shorter wavelengths than radio waves, which heat the food we eat. They are also used for radar images, like the Doppler radar used in weather forecasts. There are infrared waves with long wavelengths and short wavelengths. Infrared waves with long wavelengths are different from infrared waves with short wavelengths. Infrared waves with long wavelengths can be detected as heat. Your radiator or heater gives off these long infrared waves. We call these thermal infrared or far infrared waves. The sun gives off infrared waves with shorter wavelengths. Plants reflect these waves, also known as near infrared waves. Visible light waves are the only electromagnetic waves we can see. We see these waves as the colors of the rainbow. Each color has a different wavelength. Red has the longest wavelength and violet has the shortest wavelength. These waves combine to make white light. Ultraviolet waves have wavelengths shorter than visible light waves. These waves are invisible to the human eye, but some insects can see them. Of the sun's light, the ultraviolet waves are responsible for causing our sunburns. X-Rays: As wavelengths get smaller, the waves have more energy. X-Rays have smaller wavelengths and therefore more energy than the ultraviolet waves. X-Rays are so powerful that they pass easily through the skin allowing doctors to look at our bones. Gamma Rays have the smallest wavelength and the most energy of the waves in the electromagnetic spectrum. These waves are generated by radioactive atoms and in nuclear explosions. Gamma rays can kill living cells, but doctors can use gamma rays to kill diseased cells.
