Scope on Safety: Science storage requirements
Middle school science teachers need to address two issues concerning storage. First, if it is insufficient, they need to work with administrators to secure additional storage area(s). Second, whether sufficient or not, good housekeeping practices are in order for safety and liability reasons. This month’s column outlines some safe storage and housekeeping hints for the science classroom.

Titan Beetle--An Overview
This short video gives excellent real life, close up footage of a Titan Beetle. Probably the largest insect in the world, the adult titan beetle,Titanus giganteus, cuts an imposing figure. The adult beetle has a flattened body, long, soft wing cases covering a large abdomen, and long spiny legs. The mouthparts, or mandibles, are narrow, powerful, and distinctly longer than the head. This is a great resource to help build background knowledge and to help make real world connections

Date a Rock
This lesson shows students that age-dating rocks involves counting atoms and comparing the counts. Students use simulated rock samples, which show a highly magnified selection of 128 atoms, each sample with a different proportion of the atoms of two different elements: a parent radioisotope, and its daughter product. By counting the parent radioactive atoms and knowing the half-life of those atoms, students can figure the number of half-lives since the sample solidified, and therefore the age of

Examine animations of fault motion
Developed for high school students, this Earth science resource provides animations of each of four different fault types: normal, reverse, thrust, and strike-slip faults. Each animation has its own set of movie control buttons, and arrows in each animation indicate the direction of force that causes that particular kind of fault. The introductory paragraph defines the terms fault plane, handing wall, and footwall--features that are labeled at the end of the appropriate animations. Copyright 200

Graphic Design: Using Symmetry to Create Corporate Logos
This activity teaches students to describe three types of symmetry, to categorize symmetric figures based on type of symmetry, and to create figures using different type of symmetry. The activities use familiar logos and signs to show how symmetry is used in the world of design, and to help differentiate between the different kinds of symmetry used in these examples.

Silk: Caterpillars
If you listen closely, you can hear the sounds of a critical element in the production of silk--silkworm caterpillars dining on mulberry leaves. This episode of the two-minute radio show Pulse of the Planet focuses on how silkworms are raised. In the episode, available here in MP3 audio and text formats, a guest biochemist describes the silk farming process, noting the silkworms' dependence on large quantities of human-supplied mulberry leaves. The host points out how much silkworms grow in leng

Difference of Squares
This lesson uses a series of related arithmetic experiences to prompt students to generalize into more abstract ideas. In particular, students explore arithmetic statements leading to a result that is the factoring pattern for the difference of two squares. An excellent teaching idea on how to help students walk the bridge from arithmetic to algebra.
