Facilitated by six high school student volunteers and Dr. Lindo, many of this year’s 500 STEAM Saturday participants visited the sustainability and compost stations.
First, students and parents were asked: can we feed a plant directly with an apple or a banana? After the trivial answer (of course not!), participants went to the first station and looked for earthworms in a fish tank that mimicked their underground habitat. They then carried the worms to three different containers, created different strata, and observed how worms acted as engineers making tunnels. Parents and kids connected with nature through the re-creation of a worm habitat and observed their fascinating world. The next station offered a way to measure the food preference of worms and their excitement level. Three different menus were offered to worms: fruits and food scraps, the Daltonian, and styrofoam cups. Students measured temperature changes during the decomposition process and made side-by-side comparisons between different materials in each of the compartments and the worms’ preferences. Finally, guests transitioned to a final station where they touched the final product of the composting process and added compost and water to many of the plants we have at Dalton. They were able to address the initial question — can we feed a plant directly with an apple or a banana? — using a more informed and sustainable approach.
