    The Difference Between Rainwater and Tap Water

    Not all water is created equal especially when we're talking about the health and development of plants and people.

    Why Rain is Important

    Rain or the lack of an adequate supply can have profound effects on farming and the communities that rely on the harvest.

Intermediate Lesson 6.8 Can We Drink It?

Lesson Overview

Time to build a bigger, better water filter. This lesson explores the design attributes of a large scale water filter that students can build and use in the Lab.

Goals

  • Students will be able to describe the process of constructing a water filter to treat rainwater.

Outcomes

Students will create a high volume water filter using locally sourced materials in order to filter rainwater for use in the Lab.

Teach the Teacher

  • Filtering and Treating Rainwater
  • DIY Water Filter

Tools & Materials

  • Five gallon buckets
  • Pebbles
  • Sand
  • Activated charcoal
  • Drill
  • Shovel

Activity

The rain is falling hard, and your catchment system is at full capacity. You know the potential each drop holds. The nutrients alone could provide a welcome boost for all the plants in the Lab. But you don’t know everything that’s in the water. Rainwater touches multiple surfaces and picks up pollutants from the atmosphere long before it enters your system.

How can you be sure it’s safe for use?

Improve on your previous lesson by building a bigger better mouse trap, or water filter as it were. Scale your water filter design for bigger volume production. Think gallons not ounces and improve efficiency while you’re at it. You should also consider how your filter can be used in concert with your existing catchment system as an inline part of the overall process or as a mobile system that can be easily deployed as needed.

Start with a discussion to work out some details, then move to a design phase, and ultimately into production. Consider materials and inputs that you can source for free, perhaps even upcycle.
