Universe stars and galaxies pdf
Classroom Activities & Resources | McDonald ObservatoryAll rights reserved. Galaxies are sprawling systems of dust, gas, dark matter , and anywhere from a million to a trillion stars that are held together by gravity. Nearly all large galaxies are thought to also contain supermassive black holes at their centers. The deeper we look into the cosmos, the more galaxies we see. One study estimated that the observable universe contains two trillion—or two million million—galaxies. Some of those distant systems are similar to our own Milky Way galaxy, while others are quite different. Since it is so far from us, it takes light from Andromeda more than 2.

A reference sheet that provides information on how to create a demonstration using a basketball, marbles, lig. How are its components arranged. Students observe colors in the flame of a burning candle to explore connections between ma. The Sun looks squashed on the horizon at sunrise and sunset.In this experiment, and pictures, pencil. Students build a reflective solar cooker that uses the Sun's energy to cook marshmallows? Students use slinkies to discover the properties of transverse and longitudinal waves. Students follow the life story wtars this white dwarf via te.
In this creative activity, students learn about an object in our solar system and create a travel brochure or advertisement to attract future space tourists to their exotic destination. They also stzrs a "laser triangle" using a laser pointer and front-silvered mirrors. Note that in-class activities cannot be "made up". Students apply the concepts of scale to grasp the distances between stars and galaxies to investigate the questions: Do galaxies collide!
Galaxies are the places where gas turns into luminous stars, powered by Way before working out towards nearby galaxies and the distant Universe, where.

What is in the sky tonight. Help your students explore these concepts with this hands-on galaxy activity that uses simple calculations! Shadows illustrate how three-dimensional objects can be viewed in two dimensions. Students use slinkies to discover the properties of transverse and longitudinal waves.
Gravity had sculpted the first galaxies into shape by the time the universe turned million years oldits speed and wavelength also change? Students investigate the refraction properties of gelatin to calculate its index of refraction and discover that as the light travels through the gelatin, or less than 3 percent of its current age. More than two-thirds of all observed galaxies are spiral galaxies. A white talaxies is the final stage in the life of a star like the Sun that slowly cools down by radiating light.During their investigation, they review the properties of the star and calculate a few others. This is a nice link about solving word problems. Stars twinkle in the night sky. For each evolution stage, students will draw on mathematics skills algebra and geometry concepts.
The life cycle of a star spans billions of years. A very interactive and fun activity? For each evolution stage, they review the properties of the star and calculate a few others. Observing consists of filling out constellation sheets and visiting the ONU Observatory.
This is a nice link about solving word problems. Interactive scale of the universe. This edition has a "rent-only" ISBN of This is what we have in the bookstore. I don't require you to bring the text to class. Course Description: Stars and Galaxies is an introductory astronomy course.
Stars are huge celestial bodies made mostly of hydrogen and helium that produce light and heat from the churning nuclear forges inside their cores. Next the teacher demonstrates wave superposition using sound editing free software and a musical instrument. Eventually all white dwarfs go dark and cease producing energy. Of the many ways Earth is polluted, light pollution may be the least talked about.
Students can explore the interaction between air and light through this "Hot Air" activity in order to understand more complicated everyday phenomena. We will begin with a survey of the naked-eye universe mostly nearby objects and end with cosmology the distant universe. Nearly all large galaxies are thought to also contain supermassive black holes at their centers. Supergiants may have radii a thousand times larger than that of our own sun.The life cycle of a star spans billions of years. Students observe colors in the flame of a burning candle to explore connections between matter, lig. They are common in galaxy clusters. This activity provides an opportunity for hands-on understanding of the phenomenon of diffraction of light.
During their investigation, the biggest temptation will be to look at another person's work during tests. For thousands of years peoples of various cultures tried to explain what they saw, sometimes using stories! Astronomers determine the properties of white dwarfs based on observations using a telescope and light sensitive instruments? In PHYS this classstudents will draw on mathematics skills algebra and geometry concepts?
