The huge nutrient intake and output of our cities shapes ecosystems around them. But the nutrient flux of a city is made up determined by its individual parts: you and me, and the homes we live in. So how do you fit in?

By answering a few questions about your household, you can find out the amount of nutrients you're taking in, and how much you're releasing into the ecosystem. Click on the link to try out a version of the flux calculator on Science Buzz: What's your flux score?What's your flux score?

Discovery Education offers tools for planning and conducting a science fair, even for those without a science background.  They offer everything from project ideas, student and coordinator checklists, a six week timeline for planning, guidelines for judges, shopping lists and presentation tips for students to use.  View sample projects as well as virtual labs.

Here's where you'll find everything you need to know about the Design Squad program and Web site. Plus you can find tons of fun engineering activities you can do at home, in the classroom or with any group of kids. Use the links below to explore these areas:

Design Squad is more than just a television series.

The Design Squad Web site extends the concepts presented on the show and provides viewers with an opportunity to explore content through the lens of "engineering as problem-solving using science, math, and technology."

Engineers and educators have partnered with Design Squad to help support kids as they try out the ideas first-hand. These real world experiences give kids a stronger understanding of engineering, equip them with science and math skills, and ultimately lay the foundation they need to participate in engineering activities later in life.
