Mālama in action: KS preschoolers take on stream cleanup

April 22, 2025

Keiki from KS Preschools-Nānākuli got their hands dirty for a good cause, launching genki balls and picking up litter at a neighboring stream to learn what it means to mālama ʻāina.

Guided by their kumu, the preschoolers headed to Kalanianaʻole Beach Park and Nānākuli Stream – known to many as “Stink Pond” – to help restore its health and learn more about the ecosystem in their own backyard. The neglected muliwai is like many in Hawaiʻi, bordered by encroaching grasses and teeming with invasive fish and algae.

Genki balls, made from a mix of soil, bran, molasses and effective microorganisms, break down harmful pollutants in water. The mixture is simple enough for even the youngest learners to create, and the results, both environmental and educational, are powerful.

Kumu Hau Kaalouahi KSK’97 introduced the project to her haumāna after hearing one of the preschool ʻohana siblings share about making them over the summer and how important it was for ‘āina. The activity quickly became a way to integrate science, culture and kuleana into her classroom.

“Our ancestors were the best scientists who used their senses to navigate through life,” said Kaalouahi. “Learning about mālama ʻāina through hands-on learning experiences such as planting, cleaning and restoring natural areas helps our younger generation understand and appreciate their heritage and community values.”

Before heading to the muliwai, keiki explored how waterways affect the health of native plants, animals and people. They studied pollution, recycling and the importance of sustainable habits, while also using math and science skills to measure and mix their genki balls.

“It’s a great hands-on activity that directly impacts the environment and our connection to ‘āina,” Kaalouahi said. “Teaching keiki to protect these resources is important for maintaining this connection and ensuring a sustainable future.”

Armed with garbage bags and big smiles, kamaliʻi tossed their genki balls into the water and ran relay races to pick up litter and sort recyclables across the park. For many, this beach is a place they visit with their families, making their effort to clean it up even more personal.

“It’s the connection to ʻāina and he Hawaiʻi au,” said preschool teacher Dezra Wright. “We remind the keiki that they need to mālama where they live so it can be a safe and fun place for everyone.”

By giving back to the land and sea near their homes, these young haumāna are already learning that caring for the planet isn’t just science; it’s a way of life that goes back generations and will continue with them.
