Students in this lesson will be introduced to the concept of tides and tidal forces. By viewing a related applet which visualizes the relationship between the Earth, moon and tides, students will gain an understanding of why the Earth experiences tides. In the process they are asked to observe and explain how the relative positions of Earth, the moon, and the sun are responsible for the moon phases, ... Full description.

In this lesson, students explore how groundwater contamination can spread through aquifers by participating in a groundwater plume simulation. Students will consider where they would look to determine the source of groundwater contamination and where they could turn for assistance; explore the possible contamination of Nevada groundwater by a major nuclear test site by reading and discussing, "Concerns ...

This is a multimedia interactive simulation that teaches students about emergency preparedness, disaster safety, and weather and storm science. In the simulation, students visit a Florida family and end up preparing for and riding out a hurricane which hits during the visit. Students can track the storm on a map, watch weather updates, prepare emergency supplies, and develop a disaster emergency plan. ... Full description.

This learning unit is designed to present a means to examine what factors influence the quality of water in the Chesapeake Bay: population increase, algal blooms, endangered species (shad, oysters and blue crabs), and different watersheds (such as the Susquehanna River Basin) draining into the Chesapeake Bay bringing nutrients and pollution. Students work in groups to take on the role of scientists, ... Full description.

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 lesson plan will help students to understand that the way a community disposes of its wastewater may negatively affect local aquatic habitats, that it is possible to find wastewater-disposal methods that do not pollute, and that both governments and citizens can take action to ensure that waste water will be disposed of in a way that is not destructive. As part of the lesson, students will discuss ... Full description.

Students investigate the importance of water historically and in their daily lives and examine the nature of water as a limited resource. Working in groups, they will list the various uses of water, discuss why water is a limited resource, research technological systems that are intended to use water as productively as possible, and create "How It Works" posters for presentation to the class. The ... Full description.

As part of this classroom activity, students will record and graph temperature data to learn about the search for water on Mars. Using models of frozen and ice-free "soils" constructed from readily available materials (a list is provided), they will examine (by periodically measuring temperature and graphing the results) how the ice content of the Martian soil affects the rate at which a warm probe ... Full description.

This document provides activities and ideas for science projects that deal with water supply and quality in the Jacksonville, Florida area. Topics include the use of groundwater (and wells) as a resource, types of groundwater contamination, and information on the aquifers in the Jacksonville area. An activity is provided in which students construct a model aquifer, and suggestions are made for science ... Full description.
