"Once More to the Lake" by E.B. White
Revisit your own childhood memories of long summers and lakeside fun with E.B. White's essay, "Once More to the Lake." Included here is the actual text as well as a series of short-answer questions that follow. Not only do readers study...
Curated OER
Building A Solar Still
Students investigate the water cycle by viewing an online video. For this drinking water lesson, students create solar stills at their campus in order to purify water that is tainted. Students view a video on their computers...

Do You See What Icy?
Here is a lesson that kicks off with a question. "How does ice floating on the ocean act as it melts?" As learners investigate this natural phenomenon, they'll discover that it has a lot to do with temperature, salinity, and the effect...
Curated OER
Microfishing
Students use a simple method to collect living microorganisms from natural and/or artificial environments and develop skills in microscopy, observation, drawing, speculation, hypothesizing, oral presentation, and raising questions.
Curated OER
Density Dynamics
Students set up working models demonstrating lake turnover and the formation of deep water masses in the oceans.
Curated OER
Sink or Float Experiment
Middle schoolers participate in an experiment to determine which objects float or sink. They use different amounts of salt for the objects and discover as the salt content increases, objects will float. They record their predictions and...
Curated OER
North American Biomes
In this Science instructional activity, students color a biome map of North America. Students color the map by solving the clues listed on a separate sheet of paper.
Curated OER
Out of the Deep
Students observe, describe, and record characteristics of ocean animals (mammals and fish) and sea shells. They conduct an experiment comparing and contrasting sugar water, salt water and fresh water and create a mural of coral reef...
Curated OER
Channel Catfish
Students study the life and biology of the Channel Catfish. In this aquatic biology lesson, students will examine the external and internal features of the catfish along with their breeding habits and environment. This lesson includes...
Curated OER
New Jersey Estuaries
Students experiment to discover that salt water is denser than fresh water by creating color coded solutions. They examine how heavy rainstorms and high tides develop layers of different degrees of density.
Curated OER
Sea Water Freeze
Students observe how salinity affects the time it takes water to freeze. They participate in an experiment to determine that ice is essentially salt-free whether formed from fresh or salt water
Curated OER
Regulating the Internal Environment
This presentation begins with the many problems multicellular organisms which rely on diffusion encounter. There are many diagrams of mammalian organ structures, and they are labelled with their relevant functions. This an excellent...
Curated OER
Liquid Rainbow
Students develop their own techniques for drawing a small sample of solutions into a straw. They hypothesize ways to increase the density of water, and discuss how salt-free rainwater tends to float on top of salty seawater.

Teacher's Guide For: Water Temperature and Salinity Experiment
Students experiment with water density, temperature and salinity. In this water lesson, students observe how the coldest water sinks to the bottom of a test tube, and how saltwater sinks in comparison to freshwater.
Curated OER
Water Density and Stability Lab
Students observe how different water densities and salinity control the depth at which different water masses occur. Submarines are used as a case study. This is a well-designed with an excellent worksheet.
Curated OER
Kids for Conservation Lesson 1
Third graders observe various demonstrations dealing with the water on our earth, such as a comparison of the amount of salt water and fresh water on earth, then participate in a role playing activity in which they become a molecule of...
Curated OER
It's Too Salty!
Students examine water shortage and the process of changing salt water to fresh water. They examine a world map, define key vocabulary terms, conduct experiments involving seeds and salt water and creating distilled water, and illustrate...
Curated OER
Salt Water vs. Fresh Water
Students explore why the oceans do not freeze. They explain why they think the Atlantic Ocean does not freeze. Students are given background information about what they are doing. They create a hypothesis about what they believe...
Curated OER
Water Water Everywhere and Not a Drop to Drink!
Students describe limitations of fresh water resources on ships at sea. They realize the value of fresh water on the ocean and around the world. Students gain a knowledge of the process and economic cost of desalinization.
Curated OER
Fresh Water From the Oceans?
Students participate in an activity in which they demonstrate how the evaporations of water from the oceans results in fresh water in the form of rain. They create a saltwater solution in a flask and boil the water until most of the...
