Did you know that Galileo wasn't the inventor of the telescope? Explore the amazing history of one of the world's most incredible inventions. Learn about Galileo, the telescope, and the discoveries it has allowed man to make. A...

What have we learned since the invention of the telescope? Travel back to the year 1610 and find out what Galileo discovered, his theories, and what it has meant to space science. This clip gives learners a complete history of the...

Whether you watch this clip or assign it as homework, the results will be the same: a homemade telescope. Model-based inquiry and hands-on activities are great ways to boost interest and concept understanding. Materials, explanation, and...

According to the video, astronomy is like a jigsaw puzzle with an infinite number of pieces. The video explains the history and invention of telescopes, how they work, refraction versus reflection, and the changing technology. It...

The Kepler Space Telescope ran out of fuel in October 2018. Learn what the telescope communicated to scientists before its demise! A video lesson from the SciShow Space series highlights the important data the Kepler Space Telescope gave...

In March 2009, NASA launched the Kepler Space Telescope to look for exoplanets. Almost immediately, it identified planets and has continued to work for many years. An informative video introduces this telescope, how it works, and shares...

How does a telescope work? Find out how refraction and reflection gather enough light for us to see objects that are 200,000,000 light years away. This clip establishes the foundation for understanding how telescopes work but doesn't...

The Hubble Telescope is approximately the size of a school bus, but the new Webb Telescope will be approximately the size of a tennis court. The history of the telescope, from its invention to to what it takes to make one, is the focus...

How does a telescope magnify images? Learners first watch a tutorial explaining the basic construction of a telescope. Then they interact with a simulation that allows for changes in the location and diameter of the reflecting mirrors....

See the sun shine as you've never seen it before! Captivate your class with an activity from NOVA's Sun Lab unit. Viewers learn about the advanced satellite-mounted telescopes NASA uses to monitor the sun at every wavelength of light,...

Most of the twenty slides in this presentation include photographs or diagrams, making it an eye-catching way to teach about infrared telescopes. The pros and cons of using infrared light to study outer regions of space are explained....

Students build a telescope and give quantification of its magnification and field of view while making observations regarding images. In this telescope lesson plan, students use a simple lens to project a scene and examine various...

Students investigate the Hubble and Webb telescopes. For this space telescope lesson, students research Internet sites to find out what type of information these telescopes provide. They debate whether it is financially responsible to...

Learners create a research proposal and write letters to researchers to explain why their proposals were rejected.  In this astronomy lesson plan students use the Internet to help them to write a proposal on what they observed through a...

Students experiment with water and mirrors to better understand how telescopes work. In this telescopes lesson plan, students use water and mirrors to see how mirrors reflect light and create a magnified image.

Take a look with another perspective. Pupils read to find out what portion of the electromagnetic spectrum a space telescope sees and the difficulties of viewing infrared radiation from other objects in space. Individuals discover how...

Students explore the characteristics of stars. In this space science activity, students use the Microsoft WorldWide Telescope program to identify the properties of stars and identify the stars in the galaxy.

Students explore a web-based illustrated text and interactive graphics to determine the relationship between the operation of telescopes and light. optics. They work in small groups to become an expert on one of the ten eras of telescope...

In this telescope activity, students identify the parts of the telescope and use a telescope to observe an object in the room and outside of the room. They measure the length of the inner tube and identify the relationship between the...

In this counting galaxies worksheet, students use a photograph taken by the Hubble Space Telescope and they divide the field into 16 square areas. They find the average number of galaxies in the cells, they find the area of one of the...

In this Hubble Space Telescope worksheet, students are given a photograph of the radiator recovered after being in space on the Hubble Space Telescope since 1993. Students solve 6 problems about the impacts that left craters on the...
