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 demonstration, a soda bottle, paper and straws are used to show learners that air has mass and takes up space. The activity is from PUMAS - Practical Uses of Math and Science - a collection of brief examples created by scientists and... (View More)

In this introductory global change investigation, students gather and record visual and written data from their surroundings, and through analysis, show how the sampling window chosen for examination can affect an outcome, sometimes resulting in... (View More)

Students will "digitize" photographs of human faces using various grid sizes and shades of gray. Through this activity, they gain an understanding of image resolution and how much information is needed to answer various questions.This introductory... (View More)
