So people often travel half way around the world just to see a total solar eclipse. To stand in the shadow of the Moon is an awesome experience. For a few precious minutes it gets dark in the middle of the day.

The stars come out. And you can see the solar corona. It is well worth a major journey. The composition of the solar wind also appears to differ in the polar regions. The solar wind has large effects on the tails of comets and even has measurable effects on the trajectories of spacecraft. Nor is the amount of sunspot activity. There was a period of very low sunspot activity in the latter half of the 17th century called the Maunder Minimum. It coincides with an abnormally cold period in northern Europe sometimes known as the Little Ice Age. The Sun is about 4. Since its birth it has used up about half of the hydrogen in its core.
But eventually it will run out of hydrogen fuel. The Sun Facts The Sun is the heart of our solar system and its gravity is what keeps every planet and particle in orbit. This yellow dwarf star is just one of billions like it across the Milky Way galaxy. After learning about Earth's rock cycle and the basic characteristics of objects in the solar system, students can consider how to extend this concept to other worlds beyond Earth.
One of astronomy's first tools to measure the flow of time, a sundial is simply a stick that casts a shadow on a face marked with units of time. There are many types of sundials; an equatorial sundial is easy to make and teaches fundamental astronomical concepts. What are the relative sizes and distances of objects in the solar system?maisonducalvet.com/chicos-solteros-chapinera.php

Students create two 'mystery objects' out of play-dough to learn about scale models. Students build a reflective solar cooker that uses the Sun's energy to cook marshmallows. This activity requires adult supervision. Large telescope designs have changed significantly over the last few decades, with an growing emphasis on using segmented mirrors. This activity series consists of 4 challenges that students complete to discover how and why astronomers design and use segmented mirror telescopes. Sunspots are some of the most notable features of the Sun.
Use a telescope to track the changes in position and shape of sunspots over time. Sunspots are much more than just tiny dark spots on the Sun. This activity covers the characteristics of sunspots and uses the concepts of scale to teach students to grasp the size of these dynamic magnetic events. What is a black hole? How do astronomers find them?
What's an event horizon?
Take your students on a quest for these answers in these activities that use the Black Hole Encyclopedia. What is a spiral galaxy? How are its components arranged? Do stars collide? Do galaxies collide? Help your students explore these concepts with this hands-on galaxy activity that uses simple calculations.
A spectroscope is an observing instrument that reveals the color components of a light source. Students will construct their own spectroscope as they explore and observe spectra of familiar light sources.
Internal structure and atmosphere
Extension activities expand their understanding of different kinds of spectra and sharpen their observing skills. Students observe colors in the flame of a burning candle to explore connections between matter, light, color, and temperature — basic concepts of matter and energy. They elaborate on these basic concepts in a new context of astronomy and stars. The second half of the activity investigates star colors and relative sizes. Can gelatin like Jell-O change the speed of light?
Students investigate the refraction properties of gelatin to calculate its index of refraction and discover that as the light travels through the gelatin, its speed and wavelength also change. This activity offers students a challenge to find the index of refraction of an everyday, intriguing, translucent substance outside the standard listing of materials and refraction indexes. In this activity, students learn about the different telescopes and instruments that are available at McDonald Observatory.
Classroom Activities & Resources
They use this information to assist a group of scientists in deciding which of McDonald Observatory's resources will best suit their projects. Each "problem situation" requires critical thinking. We recommend following this activity with TAC. This activity acquaints the students with the telescopes and instruments available at an astronomical observatory: McDonald Observatory.
In this experiment, students construct an equilateral triangle using graph paper, pencil, protractor and a ruler. They also make a "laser triangle" using a laser pointer and front-silvered mirrors. Students can use the geometric properties of an equilateral triangle combined with their understanding of the Law of Reflection to decide how to place the mirrors at each vertex so that the "laser triangle" fits their equilateral triangle.

Students witness light refracting through air everyday. On hot days, "ripples" rise from the ground or roadways. Stars twinkle in the night sky. The Sun looks squashed on the horizon at sunrise and sunset. Students can explore the interaction between air and light through this "Hot Air" activity in order to understand more complicated everyday phenomena. In this activity, students test the Law of Reflection based on experimental evidence.
However, the back-silvered glass mirrors present a twist. As light travels from air into glass, it changes direction refracts , reflects off the shiny metal back coating, then changes direction again upon emerging from the glass. The reflected ray may not match up with students' expectations, and offers them a challenge to work out what happened as the light traveled into and out of the mirror. Stretching across the dark night sky, not easily visible when the Moon is in the sky, is a faint irregular glowing strip of light.
For thousands of years peoples of various cultures tried to explain what they saw, sometimes using stories. In this activity students create their own stories about our galaxy, the Milky Way. Galaxies contain billions of stars.
Students apply the concepts of scale to grasp the distances between stars and galaxies to investigate the questions: Do galaxies collide? If so, do the stars within them collide? Students learn the basics of galaxy classification and grouping, then use Hubble Space Telescope images to discover the 'morphology-density effect' and make hypotheses about its causes.
For thousands of years astronomers tried to model the motion of objects in the sky using circles or combinations of cirlces. Then in , Johannes Kepler proved that the shape of planetary orbits are actually ellipses.
