Fourth graders study the Texas City Disaster, the largest industrial accident in United States history. They examine the explosions of the SS Grandcamp and the SS High Flyer and their effect on the oil refining center of Texas City and...

Learners analyze date from the Chesapeake Bay. Using a graphing calculator, they enter the data, plot three temperatures, and create a Box and Whisker plot.

Students trace a molecule of water through the water cycle including each of its three loops. They describe why evapotranspiration demands the largest portion of total precipitation falling on a forested watershed.

Students become aware of factors that effect drinking water quality and how this could effect the health of their school environment. Students compose a business letter reporting their school water quality results to an appropriate...

Students view a video about the formation of precipitates. They complete a worksheet that asks them to identify what makes a compound form and what holds it together.

Students investigate the relationship between upstream influences in their watershed and the watershed's estuary. They apply the scientific process to test a hypothesis while examining the impact of upland activities on estuaries.

Students discuss pollution and the steps in the hydrologic cycle. They follow a drop of water through a watershed simulation. They discover the components of a water cleaning system as well.

Young scholars work together to test water samples for pollutants. They design data tables to collect and record their observations. They complete discussion questions to end the lesson plan.

Students perform an experiment in which they put different types of salts in a balloon, fill it with hydrogen gas, and ignite it. The electrons in the salt molecules are excited by the heat and release energy in the form of light. ...

Students predict which types of soils would work best for keeping contaminants contained. They comprehend that in the past, landfills have been one major source of groundwater contamination. Pupils comprehend that placing and building...

Students begin the activity by noting the many ways in which to use peanuts. In groups, they use the internet to research the work of George Washington Carver. They discover the allergies and nutritional information of the peanut and...
