This page from the Pennsylvania Department of Conservation and Natural Resources provides a number of classroom resources on topics like rocks, minerals, fossils, general geology, glaciers, earthquakes, historic geology and more. Clicking on a topic area will lead users to a webpage with resources...

This resource, from SRI International, is an on-line, standards-based, resource bank of science performance assessment tasks indexed via the National Science Education Standards (NSES) and various other standards frameworks. The resources are "collected from numerous sources, include student...

This image shows each element of the periodic table represented by a picture of something that contains that element. For example, sulfur depicts a picture of egg yolks. Symbol and color keys are included. 

Module Description: This module, from Support Center for Microsystems Education (SCME), provides an overview of personal protective equipment (PPE) used in manufacturing and laboratory environments. The module also covers "the purpose of PPE and what type of PPE is required for different tasks."...

This lab activity from the Biotechnology Alliance for Suncoast Biology Educators (BASBE) demonstrates the concept of pH. It has an activity that allows students to evaluate the effectiveness of antacid tablets including developing a testable hypothesis. The lesson includes background information on...

This 2-page learning activity, from the Advanced Technology Environmental and Energy Center (ATEEC), asks students to perform chemical analysis on different substances (common items like shampoo, vinegar and baking soda can be used) according to standard procedural methods. Information on learning...

For the phasor phanatic, created Hsi Chen Lee of Johns Hopkins University, an applet that offers 4 ways to generate and observe continuous-time harmonic phasor sums and the corresponding fourier series.

Look inside a resistor to see how it works. Increase the battery voltage to make more electrons flow though the resistor. Increase the resistance to block the flow of electrons. Watch the current and resistor temperature change. This simulation of a battery-resistor circuit is from the physics...

Circuit Construction Kit adds capacitors, inductors and AC voltage sources to your toolbox! Now you can graph the current and voltage as a function of time.This simulation of a Circuit Construction Kit(AC+DC)is from the Physics Education Technology website of University of Colorado. Included are...

Experiment with conductivity in metals, plastics and photoconductors. See why metals conduct and plastics don't, and why some materials conduct only when you shine a flashlight on them. This simulation of a Conductivity is from the Physics Education Technology website of University of Colorado....
