Kids and Horticulture: Gardening in the Classroom
Many adults have memories of planting a marigold seed in a pot at school and proudly bringing it home to present to their mom, usually around Mother’s Day. There is something exciting about planting a seed, watering it, and watching it grow that just does not compare to anything else. Many teachers are expanding on that seed of an idea and involving students in school gardening projects. An outdoor school garden is a huge undertaking and can be a wonderful school-wide project, but if time, space and resources does not make that possible, indoor container gardening provides a great way to share much of the same gardening experience with your class and it doesn’t have to involve a lot of money to get things going.
Gardens are possible in a wide variety of containers so they easily adapt to the space and resources of each class. Container gardens offer endless lesson opportunities in biology, science, agriculture, design, English, math, and social studies. Container gardening involves students in creative planning, social interaction, and sharpening their observation skills as they consider the choices for their container garden and work together to take care of their growing plants. There are many resources available through local county extension offices, but container gardening doesn't have to follow a set structure. With attention to a few basic considerations such as light, water, and fertilization, container gardens can hold herbs, vegetables, flowers, or even a combination of plants. Containers can be as simple or as decorative as your students desire. Preparing and decorating containers for their gardens offers an opportunity to explore creative design and color choices.
Learning about composting to provide organic materials used in container gardens brings in even more opportunities for lessons. There are small compost bins suitable for indoor use and even vermicomposting that uses worms to compost recycled food scraps from the lunchroom! Composting recycled materials does not get smelly as long as you choose the right types of compost. Vegetable scraps and even recycled shredded newspaper can all become compost within a classroom without the smell you might expect. If your class uses worm compost, you do not even have to worry about school holidays, as the worms will keep on working even without day-to-day attention. How many weird ways to compost can your class discover?
Making decisions and keeping records of plant growth from seed choice, germination, the growing processes, and other observations along the way to harvesting herbs and vegetables encourages English skills, writing, and record keeping. Seeing a flower bloom and die, then adding the dead plants to the compost used to start the process over again offers countless lessons about life on a level many students do not have the opportunity to experience. Insects, both pests and the beneficial types found among plants and soil, can offer opportunities to investigate environmental factors affecting plant growth. Lessons on caring for the environment can include organic gardening ideas, pest control methods, and sustainable resources. Lesson opportunities really are endless and a great reason to make container gardening part of your class curriculum this school year.
