School Gardens

This section is adapted from a handout prepared by CNPS member MaryRuth Casebeer, the author of Discover California Wildflowers and Discover California Shrubs. MaryRuth did not have a teaching credential, but loved working with young children, and taught gardening at Curtis Creek School in Sonora, California for a number of years. Her year-round program has been a tremendous success, which she attributes to the following:

  1. The gardening classes are small, only five or six students each, and are intergrade, each class has at least two students from the upper grades (4-6) matched with three or four students from the primary grades (2-3).
  2. The program has received strong support from the District Administration, the teachers, the Parent-Teacher organization, individual parents and most importantly, the students. The latter beg to be included in a new gardening class.

Classes are conducted for 40 weeks of the school year. Each student attends a weekly class for six to eight weeks, each class being about 40 minutes in length. Each new class parallels the academic quarter, more or less. Teachers release the students during their class time.

December and May plant sales pay for supplies purchased, mainly seeds and a few plants, labels and potting soil. Plants are sold to parents, employees and students at the school. The plants sell for about half the nursery price; students pay half of the adult price. And, do they buy!!

Class topics cover the following subjects:

  1. Identification, Use and Care of Tools
  2. Soil
    What is it? Observe and compare the color, texture and drainage of clay, loam, sand and potting soil. What is a good growing soil for seeds, seedlings and garden plants?
  3. Plant and Flower Parts
    (As much as possible, use garden grown plants).
    Indicate the important function of each of the parts of the plant. Using hand lens, identify the various flower parts. Explain the function of each of the flower parts. Observe the colors of the various parts and the number of petals, sepals, stamens, etc.
  4. Basic Needs of Plants
    The necessities for successful growing of plants, either in pots or garden soil: light/darkness, water, heat/cold, nutrients, space.
  5. Plant Diversity and Adaptation
    Discuss how plants change to meet their needs, how color, shape and position of leaves help California natives withstand a six month drought period or why some native plants go dormant with the advent of the hot weather. Indicate the importance of plant diversity in relation to both plants and animals
    Discuss the importance of growing California native plants as compared with growing non-native, water-thirsty plants.
  6. Pre-cycle, Re-use, and Re-cycle
    Define terms. Explain the food cycle from single-celled microbes, plants, animals, to humans to food garbage.
    Observe cafeteria garbage at various stages of decomposition. Use end product in garden soil and indicated its importance in soil building.
  7. Care of Plants
    Discussion of the most important reasons that plants fail to thrive. Generally, it is as simple as over watering or under watering.

 

Activities

  • The students have grown California wildflowers from seed in 4-inch pots to transplant into six-packs. Cuttings are also taken from native plants (purchased from CNPS plant sales) as well as plant divisions of suitable materials--iris, blue-eyed grass or other perennials and bulbs.
  • Plant Communities can be studied throughout the year--observing during the summer dormant period through September-October, the beginning of the California native plant's spring---after the first heavy rains in October-December and the burst of growth and bloom in the full native plant spring that comes with the advent of warm weather.
  • The uses that the Native Americans made of the California native plants can also be included in the curriculum. The collection of greens, such as miner's lettuce and red maids, seeds used for pinole and meal, and bulbs can be studied and the various plants grown on campus. Furthermore, the study of the care given our earth by the Native Americans is a good beginning for a pre-cycling/re-use/re-cycling lesson or program.
  • Native plants used as larval or food sources for butterflies or nectar sources for hummingbirds can be planted on the school grounds. Butterflies prefer plants in sunny areas. Plants that attract other birds can also be a focus of classroom studies. Students can observe wildlife in the garden and their appearance at various times of the year.
  • MaryBeth suggests the following publications for more ideas and other plant-related activities:
    • Botany for All Ages
    • GrowLab
    • Activities for Growing Minds

(Fourth Grade--Social Studies and Science)

California has high mountains, valleys, ocean coastline, and many rivers and streams. It supports grassland, oak woodland, chaparral, riparian and forest habitats (communities). The varied settings in California supported many different tribes of native people prior to 1700.

Food resources available to native people (California Indians) were bountiful. California supported the highest density, non-agricultural (farming) population in North America. In 1769, when the first Spanish colonists arrived, there may have been 300,000 Indians living in California (west of the Sierra Crest).

Native Californians were hunter-gatherers, which means they ate wild plants and animals that they could gather or capture. Women usually foraged for plants and men fished and hunted. Native Californians had to be especially attuned to the seasons. They had to know where each variety (species) of edible plant grew and when its fruits because ripe. An error of a week or so might mean the family or band would go without a particular food, a supply of seeds or plants for basketry, or a needed tool for an entire year, until the required plant would once again come into its useful stage. Many tribes moved with the seasons to gather plants or hunt coinciding with plant ripening or animal movements.

Native plants had many uses. In addition to being gathered for food, they were used for shelters, for clothing, baskets, dyes, weapons, cosmetics, and medicine.

In many cases the work of gathering plants fell to the women and children. Cleaning seeds and grinding acorns took a lot of time. Information on plants was passed on to children while they collected and prepared plants with their mothers and other women of their family group. By the time children were nine or ten, they could recognize hundreds of different plants, knew where they grew, and which parts of the plants were useful.

From Wetlands (Swamp, Riparian, and Pond Communities)

Plants were tended to get the right kind of plant material for basket making. Roots of sedge were transplanted and willows pruned and thinned for harvesting each year.

Plants used for food included the young shoots and tubers of cattail (Typha latifolia)

From Grasslands and Chaparral Communities

Plants used for food

Pinole is the name given to meal made from small seeds. Seeds were collected and cleaned of chaff. The clean seeds were placed in a basket with coals and tossed. Seeds were then ground and sifted. It was eaten by pinches taken with the fingers. Seeds for pinole were collected from chia (Salvia columbariae), red maids (Calandrinia ciliata), and grasses such as purple stipa (Nassella pulchra).

Greens

After eating primarily highly starchy foods or meat, Indians welcomed the coming of spring. Miner's lettuce (Claytonia perfoliata), clovers (Trifoliumsp.), braken fern (Pteridium aquilinum var. pubescens), and monkey flower (Mimulus sp.) were some of the plants collected and eaten as greens in the spring.

Bulbs

Brodiaeacalochortus and other lilies were harvested with a digging stick. Tubers such as yampah were also gathered and used for food.

There were many uses of soap plant (Chlorogalum pomeridianum)-- including fishing without a hook. The bulb was mashed up raw and placed in streams. Fish would float to the surface and could be skimmed out with sieves of willow. Other uses of the soap plant parts: fibers around bulb were used for brushes and the bulb itself was used for shampoo.

Berries

Plants with berries are found in chaparral, woodland, and riparian plant communities. Berries were eaten raw (blackberries), roasted or parched (toyon).

From Oak Woodlands

Plants found in oak woodlands were used as a source of basketry material, arrow wood, tools, and food.

In the fall acorns were knocked from oaks with a long pole and collected in large cone shaped baskets. The large baskets, called burden baskets, rested on the back like a back pack and was held up by a wide band across the forehead. This left both hands free to gather acorns. Good harvesters could collect up to 75 pounds of acorns in an hour.

Before using, acorns must be cracked open and pound (or hit) in a mortar or in a small depression in a rock outcrop. The pound acorns were sifted to remove large pieces that needed to be pounded again. A brush made of soap plant fibers was used to sweep up stray bits of acorn meal so none was lost. After pounding and sifting, the acorn meal must be leached several times with water to remove bitter tasting tannic acid from the meal. The meal was then cooked as mush or bread.

Another nut less commonly used was California buckeye. Seeds are poisonous unless roasted, ground and leached. Buckeye was used primarily when the acorn crop was poor.

As described above, berries, bulbs, and greens were also used in oak woodland communities.

From Forests

Pine (P. sabinianaP. jefferyi) roots were used to make patterns in baskets.

Pine nuts were collected and used for food.

Large burden baskets for carrying big loads of acorns and other foods often had a foundation of split roots of cedar, gray pine or other conifers.

Medicinal Plants

Medicinal Plants were collected from a variety of plant communities. Some of these plants include:

  • Yerba buena is a low-growing, prostrate plant in the mint family. It grows in woodlands along streams and in redwood forests and was used to make a tea to relieve colic.
  • Horse-tail (Equisetum sp.), grow along streams. It was dried and burned and the ashes used on sore mouths.
  • Yarrow (Achillea millefolium) was used to make a tea for the treatment of consumption, stomach ache and headache. Lotions were also used for sore eyes.
  • The leaves of California bay (Umbellularia californica) have been used for headache, stomach ache, and to repel insect pests.
  • Oaks were used in a variety of ways. Bitter tannins from acorns, bark, and insect galls on oaks were used to treat a variety of ailments including open wounds, bladder problems, and intermittent fevers.

LOCAL EDUCATIONAL RESOURCES

Peterson Nature Area
Originally planted approximately 30 years ago, the Nature Area contains well established native plantings from eight biological communities; grassland, pond, swamp, redwood forest, riparian community, deciduous forest, chaparral and bog.

Teacher Bryan Osborne, established the two-acre science study area in 1970 and recently established a new pond area. Mr. Osborne is a mentor teacher who has developed curriculum materials and labs for the Nature Area. Peterson Middle School is located in Sunnyvale, within the Santa Clara Unified School District.

Hacienda Science Magnet
Originally planted in 1971, the one-acre Outdoor Classroom is used to introduce children to the natural sciences and horticulture. The Outdoor Classroom was initiated by teacher Edy Young, her husband Joe, and parents. Teacher Carolyn Flanagan has been responsible for programs since Edy's retirement.

Beginning in 1992, the San Jose Water Company, the corporate Adopt-A-School partner of Hacienda Science Magnet School, parents, and some 30 Bay Area businesses completely renovated the Outdoor Classroom. These renovations included the construction of new ponds and a stream, a programmable irrigation system, and a 625 square foot covered outdoor study area with benches and tables.

Biological communities represented in the Outdoor Classroom include redwood forest, oak woodland, chaparral, grassland, streamside and pond habitats. Hacienda-Valley View School is a K-5 school in the San Jose Unified School District.
