Today’s guest blog post is provided by Joshua Harms, part of the Iowa AmeriCorps 4-H Outreach program, serving with Water Rocks! in 2018-19.
As a continuation from last month’s blog, I will be explaining another one of our great modules with Water Rocks!. Our presentation over wetlands has many interesting and important facts along with a few games as well. The module is meant to feel like the students are on a game show and we are their game show hosts. This presentation, like all the others, has been fine-tuned by our team to make it run super smoothly in the classroom with elementary and middle school students.
Our Fabulous World of Wetlands module starts with an audio “field trip,” where we have all the students close their eyes as we play some sounds from out in nature. We then ask them what different sounds they heard. After they have given us some of the different creatures they heard, we ask them where they think the sounds were recorded, hoping that they eventually answer wetlands. We then ask them to answer a trivia/evaluation question to establish their baseline understanding of the subject.
We then continue into our first game, a guessing game in which the students have to try and guess what the three main characteristics of wetlands are (hydric soils, presence of water, and water-loving plants). After the students eventually get all three things, sometimes with the help of some hints, we move on to show them three objects that represent the three main jobs of wetlands. The first object is a coffee filter and we explain that wetlands filter the water and leave it cleaner after it passes through the wetlands. The second object is a sponge and we explain that hydric soils store water like a sponge would if it was dropped in a bucket of water. The third and final object is a small house, which we use to explain that wetlands are a habitat to many different creatures. After we get done explaining the three jobs we have the students repeat them to lock the knowledge into their brains.
We then transition to talking about some certain creatures that rely on wetlands, particularly migratory birds and butterflies. We ask the students to think about if we were all to get on a bus and take a long journey down to Texas, what would be some reasons that we would stop on our journey? They usually answer with things such as food, water, bathroom, sleep, etc. We then explain that for those same reasons that we would stop, birds and butterflies need those same things and they stop at wetlands to take care of all of it along their journeys. This leads us into the next game which is Habitat Hopscotch. This game involves different states that are on the birds’ and butterflies’ migratory paths, as pictured above. But there is a twist—there are some situations that remove wetlands in certain states, which means we remove that state from the game. We then go through all the situations one-by-one, and by the end of the game, there are only three of the original ten squares remaining. That means there are not many wetlands left for the birds and butterflies to stop at!
After the completion of Habitat Hopscotch, we show two maps of Iowa, one of what Iowa looked like 200 years ago and the other one of present day Iowa. What we are showing the students is that our state used to be almost all prairie and wetlands but now the state is mostly covered by corn and beans. We then let them know that 90% of our original wetlands have been converted into other things. We also tell them that 99.9% of our state’s prairie land has also been converted. But it’s not all bad news—there has been good work with farmers to restore both prairie and wetlands on part of their land, which is great for all the creatures that call wetlands home.
This leads us into our game of Wetlands Bingo, which allows the students to see many more of the creatures that live in wetlands. After each wetland bingo, we ask that student a trivia question that gives them a chance to win a prize. When we have had multiple winners, we then finish with the same trivia/evaluation question that we did near the beginning of our presentation. We also leave each classroom teacher with a set of Wetland Bingo cards, so they and their students can continue learning about the Fabulous World of Wetlands and all the amazing creatures that call wetlands their home!
