Event-Based Science meets National Science Education Standards!


Toxic Leak!

Event-Based Science is a new way to teach middle school science. It is an award-winning, standards-based program in which newsworthy events establish the relevance of science topics; authentic tasks create the need-to-know more about those topics; and lively interviews, photographs, Web pages, and inquiry-based science activities create a desire to know more about those topics.

Toxic Leak!Toxic Leak! is an Event-Based Science module about groundwater. It uses gasoline leaks in a Charlotte, North Carolina tank farm to establish the context for exploring concepts related to the subsurface water that we call groundwater. The task in Toxic Leak! places students in the roles of high school students in a small town with a similar problem. A leaking gasoline tank at the community's general store is contaminating some wells in town. Students will acquire then use their knowledge of aquifers, groundwater, and permeability, porosity, and capillarity to help their town council select a site for a new community well. Their selection of the site will demonstrate an understanding of relevant science concepts.

NSTA Recommends Toxic Leak!


Teaching Suggestions From The Field

As with all Event-Based Science modules, much of the information that students need is provided in the pages of Toxic Leak!. However, more information may be helpful to students as they explore topics related to groundwater. Information about water usage, water conservation, wells, septic systems, soils, and environmentally safe recipes for cleaning and household products is available at the sites listed below.


Correction Alert

Jeannie Okray (science teacher at Lake Mills Middle School, Lake Mills, Wisconsin) has identified an error in the Teacher's Guide portion of the Above and Below Science Activity. One of the "Official Drilling Logs," found on page 15 of the Teacher's Guide has an error. In the right hand column, 207 Market Street should have a Well Depth of 75 feet. We are sorry for the error, please take the time to correct it now.

Barbara Jabobson (member of the Rhode Island Geography Education Association) has identified an error in the Above and Below Science Activity found on page 26 of the student edition of Toxic Leak!. In procedure 4 you will find reference to the scale to use when making a subsurface profile. The wording states "use the scale 1 inch = 2 feet." Barbara reminds us that the correct terminology is "use the scale 1 inch represents 2 feet."

Please let us know if you find other errors.
