Become a Jr. Marine Biologist!
Water Science: Fresh Water vs Saltwater Adventure Kit
Turn curiosity into a lifelong love of science and the ocean. Instead of simply reading about fresh water and salt water, your child will investigate, build, create, and discover how these two very different waters shape life on Earth.
What’s Inside
Five hands-on STEAM activities designed by real marine educators:
- Float Test: Test how objects float differently in fresh water versus salt water.
- Fresh vs Salt: Compare the properties of fresh water and salt water.
- Layered Waterways: Build a layered water density model.
- River Flow and Erosion Model: Explore how rivers shape the land through flow and erosion.
- Filtration & Habitat Comparison: Test water filtration and compare freshwater and saltwater habitats.
Every kit also includes collectible flashcards, an illustrated guide, marine science vocabulary, and a personalized Certificate of Completion.
