  1. Our Universe Lessons 1-2

  2. Our Universe Lesson 1: Light and the Universe

  3. Lesson Objectives

  4. Our Universe Planets Stars Solar Systems Galaxies

  5. Waves • Waves are a transfer of energy from one point to the next. • A photon is a particle of light that travels in a wavelike pattern at the speed of light,

  6. Features of a Wave

  7. Features of a Wave

  8. Features of a Wave

  9. Features of a Wave

  10. Features of a Wave

  11. Features of a Wave

  12. Features of a Wave

  13. Frequency and Wavelength

  14. Types of Waves Longitudinal Waves and Transverse Waves ***A medium is any form of matter through which a wave travels***

  15. Overview

  16. Frequency and Wavelength

  17. Measurements

  18. How are Certain Waves Created? Microwaves are produced when magnetic and electric fields are applied perpendicular to each other Infrared radiations are produced when a changing electric field creates a changing magnetic field perpendicular to it Gamma rays are produced by applying electric and magnetic fields at right angles to each other

  19. ***Sounds needs a medium to travel though, light does not*** ***Light travels the fastest in a vacuum traveling at 300,000 km/sec***

  20. How far away is it • Light year - the distance light travels in one year. Although the term may sound like a measure of time, it is a measure of distance. The best method to measure the distance to a staris to calculate the variations in the position of the star due to movement of Earth in its orbit.

  21. What and how to turn your work into your teacher: 1. Go to the “Assessments” tab: 2. Click on the “S1 Our Universe 01; Light and the Universe”

  22. What and how to turn your work into your teacher: 3. Answer all questions and at the bottom check the box, and finally click “submit”.

  23. Our Universe Lesson 2: Exploring the Universe

  24. Lesson Objectives

  25. Constellations • Groups of Stars • Named after ancient heroes, gods, or other creatures • Used as a navigation system before we had better technology

  26. Space Travel Time Line 1990-1999 Continued exploration with unmanned space crafts 2011-2021 What do you think? 1970-1979 Exploration with unmanned space crafts 1951-1959 First orbiting satellite - Sputnik launched by Russians 2000-2010 More manned space travel and exploration of Mars 1900-1950 Robert Goddard believe space travel is possible 1960-1969 Busiest time in Space Exploration. First manned mission landed on the moon 1980-1989 First close-up look at comets

  27. Why Travel to Space? • Discoveries and inventions used for space helped create products we use in the home. Let’s take a look http://www.nasa.gov/externalflash/nasacity/index2.htm

  28. Was Great for the Florida Economy

  29. Telescopes Uses lenses to focus the light

  30. Telescopes Uses mirrors to focus the light, which reduces distortion

  31. I can’t see it • Certain types of waves of not able to pass through the atmosphere so the best placement for a telescope when observing space is space.

  32. What and how to turn your work into your teacher: 1. Go to the “Assessments” tab: 2. Click on the “S1 Our Universe 02: Exploring the Universe” This assessment can be confusing so please visit www.flvsess.com for an instructional video on how to complete it.
