Amazing to have such control over a virtual plastic hemisphere and watch as the sun makes its path across the sky.
The Big Dipper In 3D
Construct the Big Dipper and view this famous asterism from a galactic perspective.
THE ELLIPSE
In this lab, you'll construct 2 ellipses, and examine and measure them to determine some of the fundamental properties of ellipses.
Angular Diameter Of The Sun
When we think of size, we usually think of units such as meters or liters. But we can measure the apparent size of an object in in degrees of angle. The diagram above shows that the apparent size of the moon is about half the apparent size of a dime held
The Expanding Universe Lab
In this activity, you will use Hubble Space Telescope Images to view how objects in the Universe change and create scientific models of the Universe.
Ellipse Lab
A step by step procedure on drawing an ellipse.
Angular Measurement Lab
Students will determine the angular size of their thumbs and fists so that they can be used as angular measuring tools. The students will then use their new tool to make measurements in the night sky.
Parallax Lab
Students will use parallax to determine the length of their arm.
Apparent Motion Of The Sun
Using the sun's motions flash file, students will investigate the sun's apparent path through the sky and how it changes with the seasons and the location of the observer.
Sun's Path Lab Activity
This computer-based lab has students test their understanding of the sun's apparent movement (within an observer's celestial sphere) using a University of Nebraska interactive animation. Daily and seasonal changes are covered in this activity.
