April showers bring May flowers, unless you live in parched places like California. But even soggy cities shouldn't take fresh water for granted. This precious resource makes up just 3% of Earth's total, most of it trapped in glaciers. While billions lack sanitation worldwide, Americans use 100 gallons a day. Your environmental engineers will dive into this month's activity marking Water Week. Go with the flow!

| Activity: Groundwater Detectives
Teams of students in grades 5 to 7 locate a contaminant spill in a hypothetical site by measuring the pH of soil samples. They then predict the direction of groundwater flow using mathematical modeling and use the engineering design process to come up with alternative treatments for the contaminated water.

Feature: Flush with Savings
When it comes to wasting water, toilets are America's top culprit, guzzling 27 percent of a home's daily flow - or about 75 gallons a day for a family of four. Now a pair of Cooper Union engineering students have designed a clever way to slow the flow.

| Spotlight: Inspire Your Math Students
 Math can be a tough sell. Many students think it's too hard, or that they're no good at it. It doesn't have to be this way. Stanford Graduate School of Education Professor Jo Boaler has designed a free program for teachers to change mindsets and inspire their fifth through ninth graders to think more deeply in mathematics.
