Think back to your childhood and recall some of your happiest moments. What were you doing? Where were you? Who were you with (if anyone)? Last evening, my family was out on a late evening walk to go look at the fireflies that grace us with their diamond-like sparkling at dusk on these warm summer nights. The wetlands near our house seem almost magical with the thousands of fireflies that surround us as we stroll down the path. The sight of the twinkling fireflies always inspires my daughter to break out in her sweet, made-up songs while the rest of us listen, smile, and walk quietly beside her. As we made our way back home, we all started to talk about what makes us happy (I guess the fireflies inspired us). All of our answers contained one commonality: being outside. Happiness for me is hiking, spending time at the cabin, and gardening; my husband said playing soccer, fishing, and camping; my daughter piped in with spending time with the chickens; and my son said exploring or treasure hunting. Now, my son doesn’t go treasure hunting for items like money, jewelry, etc., he, for the most part, hunts for natural treasures. Like tadpoles! Catching Tadpoles Late in the spring, when the edges of the lakes or creeks begin to warm up from the sun, tadpoles start to emerge from their eggs and swarm the shallow waters. This year my son had his trusty sidekick (my daughter) join him in his treasure hunt for tadpoles. The two amigos collected the supplies needed for the hunting expedition and set out on their tadpole hunt. Supplies needed for tadpole hunting: bucket minnow net (using hands works too) With feet sloshing in and out of the shallow, warm water, my son and daughter slowly and carefully tiptoed through the marshy edge of the lake. Within minutes I hear: “Oh my gosh! There are millions of tadpoles in here! Mom, you have got to come and see this!” I could read the excitement on my kids’ faces as they scooped up tadpoles and plopped them in the bucket. My son also pulled out some type of aquatic grass to add to the bucket, not only to give the tadpoles shade if they needed it, but to give them food and oxygen too. After collecting quite a few tadpoles, we brought the bucket home and constructed a nice home for our tadpoles to grow in. Building A Make-shift Tadpole Pond A tadpole home needs: Fresh water from a lake, pond, or creek (tap water has too many chemicals for tadpoles to live in). A large, shallow container (we use an old saucer sled). Rocks or other items that break the surface of the water (when the tadpoles morph into frogs or toads, they need a way to get out of the water and breath air). Food such as algae, natural organic matter that has decomposed on the floor of the lake, and other aquatic vegetation such as duckweed (most of these things can be found in the environment you found the tadpoles living in). Observation After bringing the tadpoles home, my children decided to explore the tadpole water as they added the tadpoles to their make-shift pond. For hours, the two of them sat exploring the creatures in the water with their net. Every new organism was put in a separate clear container for observation. They found, snails, clams, minnows, tiny water bugs the size of a deer tick, and a fresh water shrimp! We have had the tadpoles in their pond for over a month now. According the Minnesota DNR, Minnesota frog and toad species can take a little less than two months and up to two years to make the metamorphosis from tadpole to adult frog or toad. Within the past month most of our tadpoles have begun to grow their legs and arms, and some have morphed from the aquatic vegetarian with tails and gills, to omnivorous toadlets (that eat insects) with limbs and lungs. The toads you see above still need to develop their tough bumpy skin, and at this stage, they are smaller than my pinky fingernail. How is the rest of the pond life fairing? The duckweed in our make-shift pond has at least tripled in number, the aquatic grass plant is still healthy, and the shrimp, minnows, snails, and other aquatic species are alive and well. We have ourselves a healthy microcosm we get to observe each and every day. What a fun and interesting learning tool! Microcosms are a self-contained model of something that is much bigger in size. Our microcosm is a pond, complete with tadpoles, shrimp, minnows, aquatic plants, snails, and mud. We’ve also had rain that continues to fill our pond with natural water a few times per week. This year, our pond has been completely self-sustaining. After setting up the pond, we’ve had to put no work into it. The only work we do is to sit and gratefully observe. Embark On A Treasure Hunt For Tadpoles Seeing the complete metamorphosis from tadpole to toad has been so much fun for our whole family. Once the last toad leaves our pond, we will return the water and the rest of the pond inhabitants back into the lake. I urge you to go outside on a treasure hunt of your own in search of tadpoles. Then you can enjoy a summer full of exploration, transformation, learning, and excitement by the side of your own little pond.
Outdoor Activities
Sweet Clover, Summer Memories, and a Wildflower Bouquet
As the kids and I took a walk down our road to the lake, the intoxicating smell of sweet clover, vanilla mixed with fresh-cut hay, permeated the air. Late June in Minnesota is when the summer wildflowers awaken and adorn the sides of the roads, prairies, and edges of our 10,000+ lakes. On this particular day, my daughter started collecting wildflowers on the side of the road as we walked toward the lake. “Mom, I’m going to make you the most beautiful wildflower bouquet today.” As my daughter waded through the tall grass and wildflowers, she gathered: Black-eyed Susans, Prairie Fleabane, Tufted Vetch, Virginia Waterleaf, Yellow and White Sweet Clover, Ox-eye Daisies, Queen Anne’s Lace, and Red Clover. Once we arrived at the lake, my son picked an exquisite American White Water Lily, also known as the Fragrant Water Lily, to add to the bouquet. Before long we had a beautiful wildflower bouquet of all different colors, textures, and scents waiting to adorn our kitchen table. My family has been picking wildflowers along the roadside on our walks for year. One thing that always comes to mind, when reminiscing of these ventures, is the smell of sweet clover. In fact, my children have learned to identify sweet clover when it emerges from the soil in the early spring. First, there is excitement at finding the plant itself, but then a serious race ensues to see who can pick and smell the first sweet clover leaves of the year. There is nothing like the smell of sweet clover, especially on a warm summer day like today. Years ago, as a teenager, I remember helping my boyfriend (who is now my husband) with his summer lawn mowing jobs. There was this particular spot in a yard that smelled especially sweet every time we would mow. Determined to identify the plant, I would stop and search high and low for the plant that smelled so sweet. Finally I found a plant that appeared to be a type of clover (three finely-toothed leaflets). After my job, I remember going home and telling my mother about this clover plant that had the most wonderful smell. She said “Oh, sweet clover! That was your great-grandpa’s favorite smell as well.” Little did my mother know, that my great-grandfather had actually written a journal entry about his memories of clover. What I remember was that mother laid me in the shade at the edge of the field and cocked the hay as my father raked it. The smell of the Red Clover drying and the humming of the bees comes back vividly now as I write of this happening. ~Roy Falk My mother’s aunt (who typed up my great-grandfather, Roy Falk’s, journals) noted how incredible my great-grandfather’s memory must have been to remember incidents that happened before he could even sit up on his own. I was also surprised, but I know it’s not unheard of. In fact, I remember one incident that happened when I was a baby in a walker. I was at a family friend’s house, and as I was wheeling around, the dog who lived at that house accidentally pushed me down the stairs in my walker. I was amazingly unharmed, but the memory of tumbling down those stairs and being terrified is still sharp in my mind. The sweet smell of the Red Clover and the buzzing of the bees must have had quite an impact on Great-Grandpa for him to recall this memory so well. After reading Great-Grandpa’s journal entry, I was interested to see if there was a purpose of the clover being in the hay field. According the Minnesota Department of Natural Resources (DNR), clover was brought over to the United States from Europe in the 1600’s. It was used as a forage crop (to feed livestock) and as a cover crop (where it is used to keep weeds down and enrich the soil). Clover plants have very long tap roots that extend several feet below the top soil. This tap root brings nutrients such as nitrogen up to the top soil, nourishing nearby shallow-rooted plants. I wish I could have been sitting next to the field with Great-Grandpa, listening to the bees and smelling the hay and clover as it dried in the fields. As I’m writing this, my husband and children are imploring me to accompany them on our daily walk. I think I’m ready to go out and smell the sweet clover again after sharing this story. I urge you to make your way outside and embark on a journey to look for some summer wildflowers. You may just come home with a beautiful bouquet, and if you’re lucky, you’ll catch the scent of vanilla and fresh-cut hay drifting the air.
