Fresh vs Salt Water Science Kit for Kids (Ages 4-12)

This Marine Science Kit transforms your child into a Jr. Marine Biologist through 

5 interactive STEAM projects that blend Science, Technology, Engineering, Art, and Math.

Created by real marine educators, this hands-on ocean learning experience brings the wonder of the sea to your doorstep. Kids explore freshwater and saltwater environments through comparison, water science, and creative engineering — while building confidence, curiosity, and critical thinking skills.

Each kit includes five themed Marine Biology projects designed to spark imagination and ocean discovery:

1. Float Test – Test how different objects float in freshwater versus saltwater and discover why density makes the difference.
2. Fresh VS Salt – Compare the properties of fresh and saltwater and learn how each supports different marine life.
3. Layered Waterways – Build a layered water tower to see how salinity and density create distinct water layers.
4. River Flow and Erosion Model – Design a model river to observe how flowing water shapes coastlines and carries sediment to the sea.
5. Filtration Experiment – Build a simple filtration system and learn how nature and technology clean water for drinking and habitats.
    

We make ocean science fun and accessible for every age learner.

• Ages 4–6: Simple, hands-on play-based discovery.
• Ages 7–9: Deeper science experiments and creativity.
• Ages 10+: Independent exploration and real-world marine research skills.
