Twinkle, Twinkle, Little Star Lab

Stir chocolate drink mix into hot and cold water to see if there is a difference in how quickly it dissolves. Number three in a six-lesson unit on dissolving, this installment investigates the effect of temperature. If you consult the...

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...

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...

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...

This is one heavy video! Introduce the topic of neutron stars with a brief but informative resource. Young astronomers discover the history of neutron star research, the conditions present in and around a neutron star, and the...

Reach for the stars with a fun space science video! Viewers learn about the different types of stars in the galaxy, as well as the ways to organize and classify them based on color and age.

Do you know why stars twinkle? You will after watching this clip from "Tell Me Why." A top astronomer explains that stars twinkle because of the earth's imperfect atmosphere. Each imperfection or irregularity cause the light from the...

Space explorers take a virtual trip around the sun right within your classroom! They stand in a circle facing away from the "sun" (a lamp) in the center of the room. As they move according to your instructions, they view different...

Let the star's color be the guide! The color of a star indicates its temperature and its mass and distance affect the gravitational force. The lesson presentations address these concepts as well as how the theory of special relativity...

Do stars age gracefully? Young astronomers use colored paper and data on luminosity and temperature to model the changes of a star during its lifetime. They then compare models of stars of different mass and radii.
