In this activity, learners discuss the different salinities of oceans, rivers and estuaries.

In this creative roleplay activity, learners will explore the various processes of the water cycle using movement, sound, and props to aid in comprehension.

In this activity, learners are introduced to robotic submarines called gliders. Learners make “gliders” from plastic syringes and compare these to Cartesian bottles and plastic bubbles.

In this activity, learners are challenged to design a planktonic organism that will neither float like a cork nor sink like a stone.

In this activity, learners use plastic water bottles, wood, and water to build an inexpensive and portable tool to demonstrate one atmosphere of pressure at sea level.

In this activity, learners act as water molecules and travel through parts of the water cycle to discover that it is more complex than just water moving from the ground to the atmosphere.
