This is a lesson about Saturn. Learners will create a multilayered book with diagrams of Saturn showing its various layers, ring system, and many moons. To enhance background information on Saturn, students will practice listening to informational... (View More)

This lesson is comprised of four parts grouped to enable student appreciation of the importance of making accurate scientific observations, descriptions, and drawings. In part one (The Truth is Out There), students describe an object given to them... (View More)

In these activities, students investigate how gamma ray bursts emit energy in beams (as opposed to emitting light in all directions) and investigate the implications of this on the total number of gamma ray bursts seen in the universe. This activity... (View More)

In this activity, students determine the direction to a gamma ray burst using the times it is detected by three different spacecraft located somewhere in the solar system. We assume that all the spacecraft are in the plane of the Earth's orbit... (View More)

In this activity, students look at the distribution of aluminum foil balls arranged in a circle on the floor, and compare them to the distribution of gamma-ray bursts on the sky. This activity is part of a unit designed to use gamma-ray bursts -... (View More)

In this hands-on activity, students analyze the data on Mystery Object Cards, observe that astronomical objects have many observable properties, and discover that these properties allow scientists to categorize astronomical objects into different... (View More)

This activity provides tips and ideas for helping children do science with a digital camera–and have fun while doing so. For example, cameras can preserve the presence of transient events like clouds, contrails, rain, snow, air pollution and... (View More)

In this activity, students solve exponential equations where the unknown is contained in the exponent. Students learn that taking base-10 or base-2 logs pulls down the exponent, allowing the unknown to be isolated and solved.  This activity is... (View More)

In this activity students convert antilogs to logs, and logs to antilogs using scientific notation as an intermediate step. They will thereby develop a look-up table for solving math problems by using logarithms. This is activity D2 in the "Far Out... (View More)

In this activity, students construct base-two slide rules that add and subtract base-2 exponents (log distances), in order to multiply and divide corresponding powers of two. Students use these slide rules to generate both log and antilog equations,... (View More)
