"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
Modeling Estuaries
Students create a model estuary. In this modeling estuaries lesson plan, students identify characteristics and mix water of varying densities. Students form a hypothesis, conduct an experiment, and analyze the results.
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...
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
The Weight of Water
Students examine how salt water is more dense than fresh water. They discuss how manatees need to float and sink, conduct a sink or float experiment, and conduct an experiment with eggs and salt and fresh water.
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
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
Polar Trec
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
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.
California Academy of Science
A Day inthe Life of a San Francisco Native Animal
Although the lesson is specifically about the San Francisco Bay area, it's good enough to be adapted to any local region. Children research what the landscape in San Francisco was like prior to settlement, they consider the types of...
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
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
The Intertidal Zone: Tides and How Creatures Survive
Students study the properties of ocean water and tides and learn about animals that live in intertidal zones. In this intertidal zone lesson plan, students participate in classroom stations to learn about fresh water and salt water, cold...
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
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
Salinity and Brackish Water Systems
Students are able to tell the difference between brackish and salt water. They also are able to distinguish water qualities specific to each type of water. Students answer various questions about all types of water.
Curated OER
Water, Water Everywhere, and Nary a Drop to Drink!
Students sing the continent song and locate oceans between the continents on a map. They read "They Earth is Mostly Ocean" and copy notes into their journals. They watch a demonstration of water and saltwater evaporated to see what is...
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...
