Enceladus, I Barely Knew You
Read the Fine Print
Rating
0.0 stars

This is a lesson that applys occultations to Saturn's Moon Enceladus. Learners will establish whether Saturn‰Ûªs small moon, Enceladus, has an atmosphere, whether that atmosphere is over the entire planet, and what creates Saturn‰Ûªs E-ring. The activity is part of Project Spectra, a science and engineering program for middle-high school students, focusing on how light is used to explore the Solar System.

Envisioning the Future by Examining the Past
Rating
0.0 stars

The forests of North America have seen plenty of change in a pretty short period of time, at least geologically speaking. Up until about 18,000 years ago, the Laurentide Ice Sheet covered Canada and much of the eastern United States. When temperatures climbed and the ice sheet retreated, forests gradually reemerged. But how? Did pockets of trees find refuge in sheltered areas during the Ice Age? Or were all tree species pushed to the southern tier of the United States, only to spread north again after the ice disappeared? Scientists still debate the topic, but one thing is clear: today‰Ûªs forests in the eastern United States bear little resemblance to post-glacial forests. Starting with European colonial settlers and marching through four centuries of development, drought, and fire, the tree cover of North America became fragmented.

Estimating Planar Areas Using Analogue Methods
Read the Fine Print
Rating
0.0 stars

This math problem determines the areas of simple and complex planar figures using measurement of mass and proportional constructs. Materials are inexpensive or easily found (poster board, scissors, ruler, sharp pencil, right angle), but also requires use of an analytical balance (suggestions are provided for working with less precise weighing tools). This resource is from PUMAS - Practical Uses of Math and Science - a collection of brief examples created by scientists and engineers showing how math and science topics taught in K-12 classes have real world applications.

Evidence for the Expanding Universe
Read the Fine Print
Rating
0.0 stars

In this activity, students examine the first line of evidence, galactic motion, for the notion of an expanding universe. By examining the spectrum of light from a galaxy, students can determine whether a galaxy is moving toward or away from us, and how fast. Students will look at optical images of four galaxies, compare the emission spectra from these same four galaxies, and measure the wavelength of the red hydrogen line for each galaxy. This activity is part of the "Cosmic Questions" educator's guide developed to support the Cosmic Questions exhibit. This activity can be used in conjunction with, or independently of, the exhibit.

Read the Fine Print
Rating
0.0 stars

Using the 5E instructional model, students discover the value of using color maps to visualize data. The activity requires students to create a color map of the ozone hole from Dobson data values derived from the Aura satellite. Students then interpret that map and compare and evaluate different color scales. Note that this is the Spanish version of Exploring Color Maps: Using Stratospheric Ozone Data.

This is a lesson about using analogues to look for life on other planets. Learners will use the results of previous lessons to write a scientific proposal to explore another planet or moon in our solar system for signs of life. This proposal should predict the types of energy and nutrients available to sustain life and describe equipment and instruments necessary for exploration and characterization of the target environment. This is activity 4, the capstone activity, in Exploring Deep-Subsurface Life. Earth Analogues for Possible Life on Mars: Lessons and Activities.

This is a lesson about measuring magnetic field directions of Earth and in the environment. First, learners go outside, far away from buildings, power lines, or anything electrical or metal, and use compasses to identify magnetic North. Next, they use the compasses to probe whether there are any sources of magnetic fields in the local environment, including around electronic equipment such as a CD player and speakers. This is the first lesson in the second session of the Exploring Magnetism teacher guide.
