To celebrate Earth Day our 3rd and 4th grade students participated at Earth Day Extravaganza at Osborn Park on April 28th!

Mrs. Kromer’s 3rd grade class has been studying pollinators for months now! They’ve been reading about pollinators online and in books, but have also been involved in conducting citizen science research in our local pollinator garden. The students are passionate about our pollinators and the troubles they face. To share their importance and struggle, our 3rd graders teamed up and designed brochures that they handed out at the Earth Day Extravaganza at Osborn Park. Along side their brochures, the students also prepared sunflower seedlings in egg shells, sunflower and wild flower seed packets, and they helped visitors to our booth create their very own seed bomb that stores a milkweed seed inside.

Mrs. Foss’ 4th grade class shared information about decomposers, which included live native millipedes and pill bugs to compare to the invasive earth worms! In the classroom we’ve been composting with Red Wigglers, a good decomposer but still an invasive species. The students have also collected citizen science data exploring the non-native worms. To collect this data, first the 4th grade class developed their own dichotomous key to help identify the different earth worms species. We then took our key outside and poured water mixed with powdered mustard on the soil. The mustard irritates the worms skin, driving them to come up to the surface where the students can grab them and identify their species. This data helps scientists to understand the movement of different worms species as they invade our continent.

The 4th grade students also had a number of small herbs to share with our visitors. The students passed out seedlings while informing the visitors about the benefits of using herbs in every day life.
