Ms Rascoe’s fourth grade science classes come out to the Jamestown Courtyard "outdoor classroom" to work collaboratively in teams of four students and to practice scientific method while observing a “one-meter square plot”: a One Small Square.
Also note: although students mark out a meter square area, we will consider what is underground and also in the air above the soil surface.
See Donald Silver's book One Small Square - Backyard for inspiration.
Each team of four students builds a one-meter square with ½ inch plastic pipes.
Each student team locates their meter square within a general area of the courtyard garden. Here are the 6 areas identified on a googlemap
The students observe their plots using senses: look closely, listen, smell and feel too...(We're not tasting things in the garden today though!)
Can you draw a bird's eye view of your one-meter plot?
What would a cross-section look like?
- What do you consider to be factors influencing the "health" of your plot?
- Factors include: sun, light, soil, rock, water, air, human interactions, wildlife, plants (abiotic and biotic factors)
Can you find and identify the plants in the plot?
Are there any insects and wildlife in your plot today?
Can you make a hypothesis or an inference about what might be under the soil surface using some of the information on the surface or by exploring carefully?
The students discuss together and diagram and write notes in their science journals, using pencil and colors.
After making observations, students begin to formulate a "health assessment" of the plot and propose design improvements.
What do we mean by “health” of the garden? We discuss ecosystems, biodiversity, wellness...
What would you do to measure and improve the health your plot?
Consider potential signs of health.
The students begin to think about introducing plants or other ways they could increase the biodiversity and improve the health of their plot.
Here are some results and ideas for improvement:

Name of this area is not very poetic!
Smells of drains from toilet inside
Looks like a plant died and left a big “gap”
After rain hear rainwater in the downpipe
Crocuses in flower but behind big shrubs so you can’t see them
|
Need to report potential drain leak to Principal and Custodians - it smells unhealthy in this area
Need to select and plant a shrub to fill the “gap”
Can anyone think of better name for this area?
Could dig up and replant crocuses in front of the big bushes so they are visible and we can enjoy them in the spring

Weather Station
|
Christmas Rose, Hellebore in flower just outside the plot
The weather station has a thermometer that might work, a rain gauge and an anemometer to measure wind speed. The anemometer is broken.
There is a birdhouse
Some plants here are Coneflowers, Echinacea that have seeds that provide food for birds such as goldfinches

|
Pyramidal Frame
|
Decide the frame is for a climbing plant
there’s a label but no plant in sight
There might be a plant waiting to come up?

K Tulip/Milkweed Garden
|
Several students remember planting tulips here when they were in Kindergarten and see lots of tulip leaves
In addition to tulips there are crocuses and lots of other plants identified as wild garlic, mugwort, chickweed
|
It might be a good idea to weed this bed of wild garlic and mugwort so that the plants intended to be here such as the tulips and milkweed can thrive more.
Also the milkweed likely will overcome some of the smaller plants here.
If milkweed is to be here - it might be more healthy for the plot to move the other plants to where they can more easily thrive?

Second Grade Garden
|
This garden lacks a poetic name!
Last week it was called the bed of the “decomposing pumpkin”
There are a lot of plants here that look interesting including lambs ear, asters, honeysuckle, buddleia and boxwoods
|
We discuss relative impacts of the various plants.
Buddleia although a nectar provider for insects can now be invasive in this area, perhaps it should be taken out and replaced with native plant?
The students like the lambs ears - it could also be divided to plant in the Sensory Garden. It needs to be managed to not overgrow its plot.

3 B’s Bird, Bees and Butterflies, Pollinators and Milkweed Garden
|
This garden has a name - although it is long.
Students find a rhizome of milkweed
There are a lot of hairy bittercress in flower, mugwort and other plants such as mint and lavender growing here
|

This lesson was 45 minutes long and gave students a quick overview and idea of what they could do for stewardship projects to help create a more healthy environment in the courtyard: to increase biodiversity.
The students are excited today by observing their selected small square plots, and feel empowered by suggesting ways they could contribute to the overall well-being of the courtyard. Students offer to be included in the stewardship and maintenance process of the courtyard, and I note proposals include: to plant seeds and plants, and to weed and water. Students begin to discuss health of the ecosystem in terms of increasing biodiversity.

Donald Silver: One Small Square - Backyard
The One Small Square lesson can be adapted for working over several class periods, and for elementary, middle school and high school students to assess for example: the health of a tree and an ecosystem, and to form an introduction to more extensive civic engagement stewardship projects.
For example:
At Gunston Middle School, I developed materials in Spanish and English for 6th grade students to observe tree health, do site assessments and catalyze stewardship projects.
At Arlington Traditional School, second grade and fifth grade classes observed their Small Squares over a year (Sept/Oct 2011) and implemented design projects.
-
- Use the One Small Square lesson as an introduction for more extensive site assessments and audits of your schoolyard and school such as required for the Eco-Schools USA program.
