Students experiment with water density, temperature and salinity. In this water lesson plan, students observe how the coldest water sinks to the bottom of a test tube, and how saltwater sinks in comparison to freshwater.

Students research the methods and tools used in ocean exploration. They, in groups, simulate an ocean exploration and consider what tools facilitate the exploration's objectives.

Learners consider the effects of temperature on water density. For this Earth Science lesson, students evaluate a demonstration of cold and hot water currents in a model. Learners use two liter bottles and varied water temperatures with...

Students brainstorm about the geographical factors that contribute to climate. They examine the impact of ocean currents on coastal temperatures.

Students discover that pressure increases the deeper the ocean becomes. They determine how water pressure differs at various depths by observing water flow.

Learners discover their absolute and relative place in space relative to water and create a book sequencing that space from most specific to most general.

Students investigate the water cycle and evaporation. They study the porosity and permeability of groundwater, and the capillary action in soil in this unit.

Students explore the different forms that water can take and conduct simple experiments to demonstrate some of its properties in each state. They watch a short video that illustrates some of these concepts.

Fourth graders write a story about how a drop of water may have traveled to school. They design a presentation on the water cycle.

Students identify and describe the steps in the water cycle. They discover the sun as the source of the cycle. They work together to create their own water cycle model.

Students explore water in depth through discussion, research, and experiment. Students apply map skills to locating particular regions of the world as they relate to water. Students predict water quality based on information researched...

Students identify and define evaporation, condensation, precipitation and also, how these interact to complete the water cycle. They identify that water moves in a contimuous cycle, which is powered by the sun. Finally, students name...

Students study the water cycle. In this water science lesson, students complete a water cycle experiment using soda bottles.

Students discuss water hazards and how to stay safe.  In this safety lesson, students read handouts and complete a water safety checklist to help themselves and their families.  

Students create observable layers in water that represent a separation based upon density differences. They model density boundaries using differences in temperature and salinity. They, in groups, perform a meaningful experiment...

Students identify the various states of water and its natural flow downward. As a class, students take digital pictures of different forms of water and create a multimedia presentation describing their photographs. Groups of students...

In this surface water learning exercise, students review water runoff, drainage basins, and river erosion. This learning exercise has 7 multiple choice and 3 fill in the blank questions.

Learners investigate the role of temperature and salinity in determining seawater density. They use a Temperature-Salinity Diagram to examine the effects of mixing on density.

Plankton are so abundant in the ocean they outweigh all of the animals in the sea. In this three day activity, groups discuss and become familiar with plankton, capture females, and look for egg production on day three. 

Several real-world problems are posed as a way to learn about vector fields in order to make some predictions after analyzing the data. The main problem comes from the tv show NUMB3RS and is based on solving a crime where a body has...

Play Jeopardy as you review what might possibly be an entire year's high school biology course! The vast variety of questions requires that you read through the slides to make sure that they all relate to your curriculum. You could make...

Is there medicine found in the organisms that live deep below the surface of the ocean? The fifth lesson in a six-part series has learners team up to research bacteria and the relationship it has with nearly every living thing on Earth....

How do chains of islands form? Young oceanographers explore the mountains of the deep in the final installment in a 13-part series. The interactive compares types of seamounts based on their overall height and height under the water, as...

There are five methods of seed dispersal. They include gravity, mechanical, animal, water, and air. Scholars study seed dispersal in lesson five of the series of six. Through discussions, hands-on analysis of different seed types, and...
