Whose Water is It Anyway?

Playing with balloons, water, oil, and bottles help put this lesson over the top! Participants use air-filled balloons in water tanks to experience gas compression. They also use oil-filled bottles to experiment with buoyancy. Included...

Ecology candidates culture pond water organisms over a few days time, then they experiment to find out how increasing nutrients affects the population. As part of a unit on water, this exploration gives your class an understanding of how...

How are maps like fish? They both have scales. The chapter includes six different activities at three different levels. Scholars complete activities using natural resources, learn how to read a map, see how to make a compass rosette,...

Create this beautiful koi pond scene using watercolor paper, crayons, and paints. This would be a fantastic project to link to a scientific study of pond life or a historical study of Japanese culture.

What is the best way to test water quality? Using plastic bottles, scholars create monitoring sensors to test water quality. Creating three different sensors allows individuals to measure water quality at different water levels.

Some species of fish are more closely related to humans than they are to other species of fish! How did so many species, that aren't closely related, develop the same body shape? A short video explains the evolution of fish. 

Students make a striking visual display showing the distribution of water on earth.

Healthy invertebrates mean healthy ponds. An outdoor activity has scholars collect samples of invertebrates from local lakes or ponds. They identify and count different species and use the information to estimate the level of pollution...

Do you know why fish are able to stay a certain depth in the water? Watch this video that discusses the physiological adaptations fish use to stay at the right depth. [5:13]

Inform your class about the adaptations in fish eyes: cones, lens size, endothermy, and speed of vision. The adaptations are related to diving behavior. Junior marine scientists compare the adaptations of four different fish species to...
