Soil Chapter - From Mudpies to Bricks

In this laboratory activity, students are introduced to the different particle sizes of soil and their properties. Using sieves, students remove organic materials and pebbles, and separate sand, silt, and clay.

Mars Meteorites "Fingerprints"

This activity is about the use of spectral data to identify mineral composition on Mars. Working in teams, students will compare and contrast spectra to identify similarities between Earth minerals and those from Mars.

All Year Long

In this activity, each student will keep a science journal during each of the four seasons. Students will record observations of the general outdoor environment they visit and then will make observations of one specific item from the habitat in each season.

Distance from the Center of the Sun's Disk

This is an activity about determining the distance of a solar flare from the center of the Sun's disk. Learners will use transparency grids overlaid on images of the Sun in order to calculate the distance of a solar flare, similar to a signal detection method used by scientists.

Space Math VIII

This book presents 49 space-related math problems published weekly on the SpaceMath@NASA site during the 2011-2012 academic year.

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.

Modeling the Universe

In this activity students are challenged to create a model of the universe in a single class period. This activity is designed to elicit student ideas and preconceptions about the contents and organization of the cosmos.

Teaching How Scientists Use Models with "What Makes Up Most of the Solar System"

This is a reading strategy guide in a series of guides that utilizes articles from the Great Explorations in Math and Science (GEMS) program.

Introduction to Magnetic Fields

This is an activity about magnetic fields. Learners will use various magnets, magnetic film, and a compass to see and illustrate what magnetic fields look like. This is the fourth activity as part of the iMAGiNETICspace: Where Imagination, Magnetism, and Space Collide educator's guide.

Climate Kids: Go Green

This game is played on an online map of a fictitious city. Players are challenged to complete an assigned trip in the most environmentally friendly way possible while staying within time constraints.
