Learners explore water adhesion and learn about why water molecules are more strongly attracted to some substances than others.

Water sticks to all kinds of things in nature — flowers, leaves, spider webs - and doesn't stick to others, such as a duck's back.

In this activity, learners use the design thinking process to design and build their own aqueduct, or water bridge.

In a class demonstration, learners observe a simple water cycle model to better understand its role in pollutant transport.

Learners design, build, and test models of "dragon boats" made from up to three milk cartons.

In this activity (page 1 of the PDF under SciGirls Activity: Bogs), learners will test cups full of potting soil, sand, and sphagnum moss to see which earth material is able to soak up the most water.

In this activity, learners observe how salinity affects the freezing point of water by making and enjoying ice cream.

In this activity, learners will use chemistry to create a night sky watercolor painting. They will experiment to learn the effects of mixing crayon, salt, and lemon juice with water color paints.

In this physics activity, learners experiment with the attractive and repulsive power of magnets.

In this outdoor game, learners role play predator and prey to explore the importance of keen hearing and silent stalking skills in the animal world.

This activity provides a hands-on experience with a scale model, a relatively high viscosity fluid, and feeding behaviors.
