Water quality is more than meets the eye. Some of its properties are invisible. Teachers using this module will focus on measurable properties of water: mass, volume, and concentration; temperature; dissolved oxygen; pH; and nitrates; and their effects on water quality. Each of these properties is the subject of a lesson plan. The lesson plans include an introduction, lesson objectives, a pre-test, ... Full description.

This module offers students the opportunity to analyze and qualitatively compare the inorganic ion content and pH of different sources of local drinking water. The students collect, organize, graph, and analyze quantitative data showing the uses of groundwater in their state. They will read, summarize, and discuss news articles about the emerging impact of merchant power plants on groundwater resources. ... Full description.

In this activity, the GLOBE Kids are excited to perform a play for the rest of the school, demonstrating what they have learned about the Earth and all of its parts. They hit a glitch when they cannot decide which Earth component is the most important, but end up learning a lot about the Earth, Sun, water, air, soil, and living things, and the way these components are interconnected. In Activity 1: ... Full description.

In this activity, the GLOBE Kids, on their second visit to Willow Creek, discover why the creek looks different. They learn about making observations, measuring water temperature and speed, and looking for critters in the water. In Activity 1, 'Magnify That', students will be able to identify a magnifying lens and its purpose. They will be able to explain how the same object looks different when using ... Full description.

In this activity, the GLOBE Kids wonder why the hummingbirds have stopped visiting their school garden.
