Buckets, Barrels and Ponds
- Describe various ways to capture rainwater
- Describe the best method for the Lab
Harvesting rainwater is a great way to reduce the water bill and nourish plants with the best possible form of water available. Plus, it’s really simple to do and can be scaled up with more sophisticated systems.
When you discover just how much water flows through your property from a decent storm it easy to make the case for rain harvesting. Consider this: just 1 inch of rain on a 1000 sq ft roof will produce 600 gallons of water. Imagine how many times you could water the backyard garden with that!
The options for harvesting rainwater are varied and can be applied in unique and creative ways. It just takes a bit of imagination and maybe a little elbow grease. But your water bill and happy plants make it worth the effort.

Introduction (10 minutes)
Begin the lesson by asking the question “How could we collect rainwater from our building?” Then describe the various methods for harvesting rainwater and state the benefits for each.
Activity (20 minutes)
As a group, walk the perimeter of the building and consider the different ways that rainwater could be harvested. Pay special attention to slope and areas where water may flow more heavily. How could water be harvested in each location? Make notes as you go.
Discussion (10 minutes)
Based on the various methods for harvesting rainwater that we’ve discussed today, which do you think would be the best for us? Could we use more than one method? Which ones? How will we store the water we harvest? How will we be able to use it in the Lab?
Assessment (5 minutes)
Use the following questions to assess the Students before and after the lesson. Tally the responses of the group in the Assessment Tracking Log for comparison:
- By a show of hands, how many of you think we could harvest enough rainwater for our needs here in the Lab?
- Now that you know different ways to harvest rainwater, do you think you could determine the best method for other buildings in our community?
