Audience: Middle school
Materials Cost: Free per student

This hands-on activity demonstrates how the combining two fluids (confluence of two rivers, Mediterranean water spilling over the straits of Gibraltar into the Atlantic) involves two processes: (1) stirring - stretching of the bulk fluid, and (2)... (View More)

We've all seen pictures of the Earth and its atmosphere as a series of concentric circles, showing the troposphere, stratosphere, ionosphere, etc., often looking like a bullseye target with the solid Earth in the middle. But if we were to draw that... (View More)

In this exercise, students learn about the historical development of the Julian and the Gregorian Calendars and design a reasonable calendar for an imaginary planet, considering the cycle period and making design tradeoffs, This resource is from... (View More)

Using the reflection seen in the bowl of a spoon as an example, this resource describes how an everyday childhood observation can lead to understanding how curved mirrors are used in telescopes and satellite dishes. This resource is from PUMAS -... (View More)

In this activity, learners practice estimation skills as they begin to explore the Hubble Deep Field image. They first give a rough estimate of the number of objects and then follow several steps, using representative sampling techniques, to improve... (View More)

In this activity, learners classify selected objects from the Hubble Deep Field based on their color and shape. They then compare their classification with a chart made by astronomers. This is activity two of four in the Hubble Deep Field Lesson... (View More)

In this activity, the problems and difficulties of determining the distances between Earth and objects in space is addressed. Learners attempt to arrange five objects from the Hubble Deep Field according to their distances from Earth. After making... (View More)

This is a lesson about the connection between meteorites and asteroids, focusing on remote-sensing techniques using light. Learners will make and record observations and measurements; analyze data and draw analogies; compare samples; measure and... (View More)

This is a lesson about the scientific careers and opportunities in Antarctic meteorite team(s). Learners will view slides and read about meteorite recovery expeditions to Antarctica, explore science careers, evaluate the characteristics and skills... (View More)
