The second graders in Lynn Hervey's Peacham, VT, class didn't know what they were using to water the corn in their GrowLab, but it soon became clear that some plants were not doing well. Lynn had collected "mystery solutions" for watering the corn plants-water mixed with motor oil from the floor of a garage, salt water, rain water, and tap water. Students cared for their plants, watered them regularly, but then, said Lynn, "I soon had a rebellion on my hands -- it was clear that some of the solutions were harming the students' precious plants.
"A bulb is a promise," Wendy Sherman tells her pre-schoolers in Sudbury, MA. "You can do your part to provide certain basic conditions for them, and then you have to hope that nature comes through with the rest." These marvelous packages, each containing a complete miniature plant and its lunch, can provide a captivating theme for exploring plant growth and adaptations, using math skills, and enriching history, while brightening winter classrooms with the promise of spring.
Amy Kjerrumgaard's first graders in Michigan have had the pleasure of exploring and tasting fruits, from A to Z. After reading Lois Ehlert's Eating the Alphabet, Amy's students got excited about locating and exploring every one of the 26 fruits described. "They were so eager to run with it," said Amy, "that I ran with them, and it developed into a year-long theme."
A simulated desert in Jan Model's Michigan classroom became a centerpiece for practicing mapping and geography skills. With support from a local horticulturist, Jan's seventh graders created a GrowLab desert environment in which they planted cacti and succulents.
Beth Garver's fifth graders in Effingham, South Carolina have learned about more than just plants using GrowLab. They've discovered the challenges and rewards of sparking young minds. In addition to conducting their own indoor gardening investigations, these fifth graders cooperatively plan, conduct, videotape, and critique science lessons with a first grade class of indoor gardeners.
School gardens can take a variety of shapes and sizes. These barrels are placed outside each classroom and can easily complement lessons.An ordinary mixed vegetable, flower, and herb garden provides endless possibilities for explorations across the curriculum. Many schools have also chosen to create special thematic gardens to focus and inspire garden adventures. Consider the possibilities of a Native American garden, for instance, for making connections to social studies and beyond.
"In the beginning of the school year, I ask my fourth graders to bring in any kinds of seeds they find outdoors, then we plant them and observe what happens," says teacher Tom Murphy from Farmington, MN. When students discovered that garden seeds like marigolds sprouted quickly, but few seeds from native trees such as walnuts and oaks began to grow, the stage was set for a year-long investigation. "Students wondered why the tree seeds didn't sprout," says Tom.
"As a way of encouraging students to observe deeply and to inquire about the natural world, I gave groups of them peanuts in shells to observe," reports multigrade St. Louis, MO, teacher Doloris Pepple. "I asked them to do just two things at first-to write down everything they could possibly observe, and to list all of the questions that their observations generated. Students came up with a range of excellent questions." The longer and more fully they observed, she notes, the more detail they noticed, and the more questions emerged. Could it grow through the shell?
The rapid disappearance of native prairies in the Midwest inspired a local farmer to help Ellen Wellborne's sixth graders in Nerstrand, MN, explore a local prairie up close. Students examined and compared different layers of prairie soil with woodland soil, then grew barley in samples of each soil, reports Ellen. "Students expected the woodlands to have deep, rich topsoil, but were shocked to see how much better the plants and their roots grew in the prairie soils," she adds. "This prompted them to want to further explore the history and ecology of the prairie."
