This lesson plan develops the concept of irrigation for elementary school level kids. The lesson plan provides two activities involving role playing. Using the role playing activites and labs, elementary students should acquire the critical thinking skills necessary to draw conclusions about various aspects of irrigation. Full description.

This module on measuring temperature and its effects on water quality is from a larger series on water quality investigations. The purpose of the site is to help students recognize that temperature can affect the organisms that live in water, describe the factors that can change the temperature of a body of water, and how to measure, graph, and interpret the effects of temperature on fish. It provides ... Full description.

This site uses Virtual Reality field trips in the Alvin submarine to the East Pacific Rise to explore hydrothermal vents. The education activites focus on 4 activities: Exploration, Observing (actual video from the seafloor), Mapping, and Collecting a Water Sample. Teaching materials for each of the explorations have been provided, each with two levels of assessment (basic and advanced). Full description.

This resource includes a classroom activity, background information and a set of temperature and surface pressure data from the Pathfinder Lander. Students analyze data on temperature and pressure graphs from the first 30 days of the Pathfinder Mission to determine whether water could have existed under these conditions. A set of 15 images is also available, which can be reproduced on a photocopier ... 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 ...

The GREEN program provides ideas and information related to creating a watershed-based educational project and is geared toward taking action to protect watersheds. There are exercises and action steps for various aspects of watershed management including monitoring, analysis, research, policy issues and background information. The site allows groups to enter their watershed monitoring or action project ... 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 ... Full description.

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 module on measuring nitrates and their effects on water quality is from a larger series on water quality investigations. It provides background information on nitrates and how it affects water quality. It also contains both a pre-test and post-test, a laboratory investigation, and a self-study game. The purpose of the site is to help students understand the sources of nitrates and the role that ... Full description.

This is a web-based activity using satellite images of the Gulf of Maine and the Carribean Sea. Students are asked to examine satellite data of sea surface temperatures. From this data they are to determine the temperature scale and how temperature differences are indicated. They also examine phytoplankton density images to determine where high phytoplankton densities are. Additional activities are ... Full description.
