Stellar Magnitudes

A wonderful lesson incorporating math and physics skills along with specific details about the planetary bodies. The cross-curricular approach makes for a valid activity to challenge multiple ages and abilities. Your class could work in...

Digital compass alignment enables navigation of the skies with true orientation at any time. Just point to the sky or "aim for the stars!" This application acts as a virtual telescope, allowing you to zoom in on any object that is...

Starting with a seemingly simple question, a video covers how many stars are visible with the human eye. Then it explains how many stars are in the Andromeda galaxy next to ours. The most interesting part is when you view a single square...

Sal makes a relatable comparison for pupils to understand the universe's relative size. The progression from a man's size to a galaxy's size is explained in terms of each object relative to the next. The multiple objects we can process...

Twinkle, twinkle little star(s)? Many of the stars above us are not alone! The narrator in the video explains the delicate balance present in binary and multiple star systems. Pupils learn about stars that orbit one another—and even...

After the previous video in this series, class members should have a general grasp of the relatives sizes of the earth and sun. This video talks further about distances between the planets and gives a sense of their and other main...

What happens when stars run out of fuel? Pupils learn the incredible sequence of events that occur as a star nears its end. The video compares and contrasts the events in low- and high-mass stars, detailing the cycle of fusion, energy...

Aspiring astronomers study stars. They compare stars and explain the relationship between radius, mass, and diameter. By creating a star simulation, they discover how a binary star system's orbit can cause changes in the observed...

Are brighter stars actually brighter? Turns out they are probably just closer! A presentation compares features of stars to our favorite star, the sun. In addition, solar lovers learn to classify stars based on their masses,...

Star light, star bright ... just how long can you wish on that star? Well, it depends on its mass. The presentation explains the life cycle of stars based on their sizes. Scholars learn about the life expectancy of a star based on the...
