# Observing Convection Currents

This model demonstrates convection currents and uses water, food coloring, a cup of very hot water and a votive candle as heat sources. Movie clips of demonstration setup and convection in action are provided. This activity is supported by a... (View More)

# Barometer Basics

This experimental activity is designed to develop a basic understanding of the interrelationship between temperature and pressure and the structure of a device made to examine this relationship. Resources needed to conduct this activity include two... (View More)

# The Moon Orbits the Sun?!

In this activity, students compute the strengths of the gravitational forces exerted on the Moon by the Sun and by the Earth, and demonstrate the actual shape of the Moon's orbit around the Sun. The lesson begins with students' assumptions about the... (View More)

# Preventing Hypothermia

In this demonstration, the process of cooling by evaporation is related to the serious health risk of hypothermia. Materials required include a desk fan, thermometer with exposed bulb, cotton or gauze, bowl, and material including cotton and wool.... (View More)

# Latitudes and Attitudes

In this inquiry investigation, students study the motion and positions of the Earth and how they affect the path of sunlight we get in different places. They discover that the Earth must be curved to account for the different lengths of shadows at... (View More)

# Mixing and Stirring

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)
