We can measure comparing an observed wavelength to a rest wavelength. Evaluation Ask the students to answer the following questions. We see them glowing in the night sky when they orbit close to the Sun and heat up, throwing off glowing tails. What would it mean if your redshift were negative? The Website was developed in part with the support of and , where it resided from 2000 - 2010. Which element is most abundant in this supernova? Now you have worked out the age of the Universe in years using real observational data! Make a note of the b-band max magnitude value down on your table.

Similarly, comets are balls of ice and minerals left over from the creation of the Sun and planets. These printable activities can be used to reinforce practice and to identify related words. For example, the rest wavelength for Hα when there is no Doppler Effect is 6563Å, if it is redshifted the observed wavelength will be longer. This can be done by finding the inverse of the value of H o 1. Dark matter is just what it sounds like: material that is not visible by ordinary means.

Welcome to , the website where English Language teachers exchange resources: worksheets, lesson plans, activities, etc. Alternatively, enter m and M for your supernovae where indicated on the ' Calculations' tab of your worksheet and the distance will be automatically calculated in Mpc. In astronomy, spectroscopy is a very useful tool because telescopes can easily measure the spectra of far away objects, such as stars and galaxies. The discovery of the expanding universe was, like more discoveries, a combined effort. Some of the worksheets displayed are Think about the universe, Size and scale of the universe, The universe work, Sixth grade universe, Color the 1 one, First grade universe, Write the name of your favorite color, Size and scale of the universe.

Why does the best-fit line to your data need to go through the origin of your graph? Next to your graph you will also notice check boxes for a number of elements, for exmaple hydrogen H , helium He , oxygen O , sodium Na. The radial velocities should be plotted in kilometres per second on the Y-axis against distance in megaparsecs Mpc on the X-axis. There have been mathematical observations of other planetary systems in the late 1990's. We recommend The Sky is Full of Stars. The Doppler Effect, such as redshift, occurs due to an apparent shift in the wavelength and frequency of a wave due to relative motion between the source and the observer.

Letter U long sound : The four search game features a universe image and letter U words with pictures and handwriting practice. Note: Be careful to ensure that you have ten different supernova spectra and have not duplicated any, as there are multiple spectra for some supernovae. Theoretically, your plot should be a straight line, but it probably isn't. Worksheet contains instructions to students on what to do, along with questions to answer. Astronomers hypothesize that dark matter exists because their work suggests that too little visible matter exists to account for the gravity and mass of the Universe. Over 20 smart worksheet generators for making fun, effective lesson materials. If you can successfully identify the element, make a note of it on your table.

They will then calculate the distance to each supernova and use the two values to plot the famous Hubble Diagram. You now have the age of the Universe in seconds! We measure the spectra of luminous objects by attaching a special instrument to a telescope, known as a spectrograph. Once you find your worksheet, click on pop-out icon or print icon to worksheet to print or download. Note: If you still cannot locate the B-band maximum magnitude for your chosen supernova, return to section I. Hubble's discovery, and the later development of the big bang theory, changed astronomy forever. Hubble's law is the name for the observation in physical cosmology that: 1 objects observed in deep space extragalactic space which is more than 10 Mpc are found to have a Doppler shift that can be used to calculate their relative velocity away from the Earth; and 2 that the velocity, of various objects receding from the Earth, is approximately proportional to their distance from the Earth. It reinforces the discussion on the night time sky and puts the facts into an understandable story.

Make a note of the observed wavelength and rest wavelength values on your worksheet. Our mobile website version is available now on your phone's web browser and. This is normally interpreted as a direct observation of the expansion of the Universe. But then, in the early 1900s scientists made several discoveries that defied easy explanation. Spectroscopy is a branch of science that is concerned with the investigation and measurement of the spectrum of light produced when matter interacts with electromagnetic radiation. Within the spectrograph, light is passed through a series of prisms and mirrors in order to split the light into its different component wavelengths its spectrum. Our Solar System includes the Sun, the nine planets, their associated moons, and countless asteroids and comets.
