Become a crime scene investigator! Learners model Dawn Mission scientists, engineers, and technologists and how they use instrumentation to detect distant worlds. After a briefing to build context, students explore interactions between different... (View More)

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)

In this lesson, students explore a discrepant event when they design an experiment to measure the rate that ice melts when in pure water versus salt water. It is designed to help students realize that a carefully-designed experiment may yield... (View More)

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)

In this activity, students use a piano keyboard to model spectral lines as musical chords. It is designed to aid student understanding of spectral analysis, what the patterns mean, how elements are involved, and how this relates to stars.... (View More)

Traditionally, spectral images are two dimensional, and related to text. This kinesthetic activity has groups of students position themselves along a printed spectrum to make spectral patterns and model various elements. Includes photos, teachers... (View More)

In this short demo/activity, a balloon with baking soda in it is stretched over the mouth of a flask or bottle containing vinegar. The balloon is tipped so that the baking soda falls into the vinegar, and the reaction creates carbon dioxide, which... (View More)

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)

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)
