Each Elementary GLOBE module contains a science-based storybook and classroom learning activities. Five (5) books are included ... Full description.

In this activity, students identify spirals and other shapes present in nature and discuss at what sizes or scales these shapes exist. Examples include a hurricane, foraminifera, nautilus, and a galaxy. They will discuss the differences and similarities of each of these spirals and investigate the powers of ten that identify the scales at which these different examples exist. Full description.

This tutorial provides instruction in algebra and trigonometry. Although intended as a refresher, it should be understandable to students who are new to the material as well as provide new insights to those who are already familiar with it. Full description.

The Central Limit Theorem applet demonstrates the central limit theorem using simulated dice-rolling experiments. An "experiment" consists of rolling a certain number of dice (1-5 dice are available in this applet) and adding the number of spots showing. This experiment is "performed" repeatedly, keeping track of the number of times each outcome is observed. These outcomes are plotted in the form ... Full description.

The Discovering Important Statistical Concepts Using Spread Sheets (DISCUSS) project is a modified and supplemented web-based implementation of the initial DISCUS materials for teaching elementary statistics at the introductory level. The site aims to integrate the powerful interactive capabilities of Microsoft Excel with the convenience of web-based resource materials using Microsoft Internet Explorer. ... Full description.
