How Distant is the Moon?--2

High schoolers examine how astronomers use parallax to determine the distances of stars in the Sun's neighborhood. They construct a pinhole protractor, and measure angles and calculate distances.

Give your pupils a front row seat at the biggest light show in the sky this year! In addition to admiring the total solar eclipse, young astronomers can explain the phenomenon with a little help from an inquiry-based lesson. The focus of...

Here is a planet worksheet in which learners read about organic molecules detected through spectral lines of the planet Osiris. They calculate the mass, the volume and the densities of common ingredients for planets including Osiris and...

Students measure distances using parallax. In this math lesson, students explain how this method helped astronomers with their studies of the solar system. They determine the length of their arm using parallax and compare it with other...

How can you determine the distance between two objects when one is incredibly far away? Discover how early astronomers and mathematicians calculated quantities such as the distance between Earth and the Sun in an insightful video. The...

More carbon dioxide exists in the atmosphere than ever in human history. An informative video introduces the topic of global warming as part of a larger playlist. It looks at possible causes such as Earth's orbit, Earth's moving axis,...

In the school courtyard, students will measure the apparent path of the sun across the sky using a toilet plunger. Students will then generate questions as to why the sun appears to move, and what is really happening in the process. We...

Ninth graders explore how Aristarchus used the position of the half-full Moon to estimate the distance to the Sun, and how he made a great error, but still figured out that the Sun is much larger than Earth.

Compare surface temperatures when the solstice occurs in the different hemispheres. Young scientists draw conclusions from their investigation of data collected using spreadsheets and a globe.

Students examine total eclipses of the Sun and their limited regions of totality. They explain that this limited view occurs because the Moon is close enough to us for different points on Earth to view it differently.
