Education Gamification

The Green LIONS Garden chased fellow classmates, made a yarn web and collaborated on answers posed as questions at our last couple of gatherings in a variety of games to weave all of the lessons they’ve learned this spring together. While we focus on sustainable gardening in our program, this subject would not be complete without tying it to the bigger community and world. If we can learn to not harm the environment in our gardening practices, find ways to utilize waste in the garden instead of disposing of it through methods like composting, and also fully enjoy the fresh, nutrient-rich produce—then we can learn to reduce our use of chemicals at home and at school, and reduce our own waste in our lives. We can go even further and begin sourcing what we don’t grow or make ourselves from local farmers and craftsman, reducing our carbon footprint through sourcing items close to home, and supporting our local community members and economy.

First, they played an energetic game of Pollination Freeze Tag! A handful of students were our honeybee pollinators with self-made wings taped to their backs. The rest were fruits and vegetables and held pieces of paper with a common fruit or vegetable pictured on one side and a flower on the other. In the center of the flower was taped a cotton ball—the flower’s pollen!

































The chase ensued. If a honeybee tagged a flower, the flower must freeze in place and give the honeybee its pollen cotton ball. If the honeybee already had a cotton ball in her possession she passed this on to the flower to “pollinate” her. Alternatively, the flower had to wait until a honeybee came back by to hand off a cotton ball to be pollinated. Once pollinated the paper with the flower picture was turned over to reveal the resulting fruit or vegetable. This helped students understand how important pollinators are to our food system.

















Next students discussed, in depth, ways we can reduce our waste in our own families. Did you know that the average American produces five pounds of trash a day? That is more for an individual than any other country in the world! We can do better.

Students learned ways they can reuse items, or to use re-usable containers and water bottles for lunches and sports events. They explored different options to reduce waste when grocery shopping—like taking their own containers to fill from the bulk bin, using re-usable shopping bags and produce bags, and not choosing too many items packaged in plastic when possible. Students also learned how to conserve water and electricity through simple, mindful actions at home and at school—like turning off lights in rooms they aren’t occupying, turning off the water when washing their hands or brushing their teeth, or plugging the tub drain before turning on the water instead of waiting until the water is heated up.

Conservation also refers to protecting our waterways. Choosing to not use chemicals on our lawns, not only helps the pollinators and other beneficial insects in our neighborhoods stay healthy, but it prevents chemical run-off into our watersheds which helps keep our waterways clean and marine life safe.

We then had an eye-opening discussion about the importance of eating locally and how much this choice can favorably impact our environment. Local, small farms, even if they are not certified organic, generally use more biodiversity and more sustainable methods than industrial farms. When produce is recently harvested this is when it is not only fresher, but more delicious and nutritious. You can only find the freshest produce from locally grown sources. It is truly more value for your grocery dollars.



















Students explored all of the steps taken to bring a food item to our plate through a fun yarn weaving activity. We posed the scenario of making a pizza and needing pizza sauce. We went through 16 steps to create our web from planting the tomato, through its route of being made into sauce and packaged and finally landing on the shelf of your grocery store. Then we proposed the scenario of finding local tomatoes, herbs and garlic at a farmers’ market or your own garden and making your own sauce. We reduced our web to only three steps! Now that is a small carbon footprint. While convenience may be the easier route, taking some time to live in line with your environmental values makes a huge difference, and is entirely doable.

















Finally we wrapped up our gaming adventure with an exciting game of Garden Jeopardy. Students are challenged to questions about pests and beneficials, conservation methods, plants in the garden, and sustainable gardening and farming methods. Garden Jeopardy is a fun way to wrap up to see how all of these topics are interwoven.

















We will conclude our spring garden program with our Harvest Tasting in a couple of weeks so come back for pictures of the delicious dishes the students and parents create to celebrate our bountiful harvest! Here is a preview with this picture of the beautiful salad created for the Teacher Appreciation Luncheon entirely from the LIONS Garden.

Friend or Foe

In any natural garden setting humans are not the only beings working, eating and traveling through. Insects, birds, small animals, microbes and more are consistently present. To successfully grow a garden without the use of chemical pesticides is to recognize which organisms may cause enough damage to your plants that your interference may be required. And when that interference is required, what might that look like?

We could easily mix up an organic pest spray using toxic-free ingredients like garlic, onions and
dish soap, and sometimes this is the best choice. Or we could investigate further and determine
why the pest is present. Are our plants or soil deficient in some way? Are there other insects or animals present that include the pest in their diet? Perhaps we can even be patient and let nature
take its course.

In trying to take control and dominate in a garden we may in turn hurt creatures and organisms that are peacefully living there and not doing harm. They may even be helping our garden, like in the case of earthworms. If we try to isolate a bug or insect we see as a pest and deal with it separately out of relation to the ecosystem in which it lives, we work against nature.

Students in the Green LIONS Garden Group learned all about common creatures we may find in our school garden and which ones may be friends and which ones foes.

A common visitor and voracious eater we see on fall and spring plants is a cabbage worm. These are the caterpillars of the cabbage moth which are the delicate white butterflies we frequently see flitting about the garden. They lay their eggs on plants of the Brassicas family and once the eggs hatch the caterpillars get busy eating. You can easily determine if cabbage worms are present from leaf damage to the plants and their droppings which are frequently seen in the center of the plant.




















Another common and unwelcome visitor is the tiny aphid. These insects live in clusters and may feed on many different types of plants. But if you see the vibrant ladybug in your garden too then you can rest assured that the aphids will be kept in check. Aphids are like candy to a ladybug. If you have an out of control aphid problem you can even purchase live ladybugs to release into your garden. They are very effective aphid disposal machines.


























The praying mantis is another welcome garden inhabitant. And like the ladybugs a gardener can purchase praying mantises for her garden in the form of praying mantis eggs. Praying mantises like to eat many different kinds of insects including many pests in the garden. It is exciting to find the presence of a this elegant insect in any garden.


















While we love to see the majestic black swallowtail butterflies in our garden, and they are
important pollinators, they also leave behind their eggs. Once their eggs hatch the caterpillars on members of the carrot family, including green carrot tops, dill, fennel, chervil and parsley. If a gardener is simply aware of this and monitors the caterpillars’ “portion control” these caterpillars can be fun to observe without eating too much of our plants. This one is mostly a friend, but in large amounts may be foe-ish.



















When we choose not to use chemicals on the plants that we will eat, it makes sense to also reduce the amount of chemicals we put on our skin. Students learned a simple recipe for a natural mosquito repellent to use throughout mosquito season. By mixing filtered water with witch hazel and essential oils they made a spray that not only smells nice, but will not harm them or the creatures in their environment.

















Natural Mosquito Repellent Spray

This recipe is for a 2 ounce bottle. Increase amounts if using a larger container. It is important to use an amber or dark bottle to protect the oils in the spray from UV light.

Ingredients:
dark glass or plastic spray bottle
filtered or distilled water
witch hazel
vegetable glycerin
essential oils of citronella, rosemary, lavender, eucalyptus, cinnamon

Fill the bottle half way with water and then fill the rest of the bottle almost to the top with witch hazel.

Add 1/8 teaspoon vegetable glycerin.

Add 3 drops each of each essential oil.

Label your bottle, attach your sprayer, and enjoy being mosquito bite free.
