Exploring the Moon
This is a teacher's guide for learning about lunar geology and regolith (loose material on the moon's surface), distance to the moon, Apollo landing sites, and life support systems. Lessons focus on calculating the distance between scale models of earth and the moon, designing a spacecraft for travel to and from the moon, the locations and geology of the six Apollo landing sites, and calculating the diameter of the moon using proportions.
Hurricanes: the greatest storms on earth
This website, provided by NASA's Earth Observatory, describes the science behind hurricanes. Sections include hurricane formation and decay, hurricane anatomy, information regarding storm surges, hurricane climatology, a description of the Saffir-Simpson scale and NASA study missions. Users will also find a list of references regarding hurricanes and hurricane science.
Stromatolite Explorer: Investigation of a Microbial Mat Community
The Stromatolite Explorer video describes an imaginary voyage inside a microbial mat. This Teacherʼs guide contains a more detailed explanation of a number of the concepts discussed in the video, including the graphs presented in the video. The animated video takes students on a journey through a microbial mat. The assigned mission is to probe a microbial mat by following an imaginary 0.10 mm stromatolite explorer as it descends through the layers. On its route, the vehicle takes chemical readi

This illustrated guide (dorsal view) to a male spider is designed to help students recognize and learn its common and unique body parts. The single Web page, which can be easily printed for use at field sites or in the lab, also includes a short description for the following labeled parts: chelicera pedipalp anterior eye row posterior eye row cephalothorax (or prosoma) pedicel abdomen (or opisthosoma) spinnerets coxa trochanter femur patella tibia metatarsus tarsus.
Some Clues to Describing and Understanding Organisms
This online guide helps students focus their biodiversity research in the classroom, field, and lab. It includes general and specific questions to consider, designed to help students see the clues they might otherwise miss and give them the vocabulary to discuss their findings. General questions include "What might this clue indicate?" and "Does the organism always occur in the same 'zone'? "Plant-specific questions range from "If it's woody, is there one main trunk (trees), or are there several
This OLogy activity serves as a kid-friendly how-to manual about searching for fossils. In Not Just Any Rock Will Do, kids learn that fossils "hide out" in sedimentary rock and see examples of shale and sandstone. Do's and Don'ts for Fossil Hunters gives kids practical tips and a list of fossil-hunting supplies. In Fossils You May Find, there are photos of common invertebrate, vertebrate, and plant fossils to guide kids. Paleontology Clubs and Web Sites lists resources to help kids determine whe

Observe how fossils can form
This website hosts an animation depicting how cast and mold fossils are preserved in the rock record. Users can play, rewind, fast forward and stop the animation at any point in the formation as well as read captions outlining the process. The animation is part of the Earth Exploration Visualization collection.
Paleo Website Java Animations
These animations give a paleo perspective on global warming, drought, and global temperature patterns. Climate Research Unit (CRU) data from 1856-1997 are used to create six animations that show globally mapped temperature. Three other animations reconstruct climates for the last 260 years and show spatial patterns of annual temperature anomalies. There are also two drought animations and an interactive presentation on global temperature patterns in past centuries.
