Students explore salt and fresh water. For this water lesson, students investigate the amount of Earth covered by water. Students compare the amounts of salt water to fresh water. Students create a visual representation to aid...

Another A+ lesson on the impact of climate change comes to you from the National Earth Science Teachers Association. In this installment, learners model the stratification of water in lakes due to temperature differences. The lab also...

Students use determination of dissolved oxygen and water temperature changes to determine the environmental impact from thermal pollution.

Students explore water properties by conducting a class experiment. In this buoyancy lesson, students utilize freshwater, saltwater, plastic cups, hard boiled eggs and food coloring to experiment with the floating capabilities of salt...

Field trip! The class will review what they know about organisms that dwell in freshwater ponds, then trek down to the old water hole to collect specimens for examination. This includes several web links, useful tips, and an excellent...

Young scholars take samples from local freshwater sources and examine them for macroinvertebrate life. They take samples from both shallow and deep freshwater environments, measure temperatures, and classify organisms found in their...

Students explore pond ecosystems.  In this pond organism activity, students will use pond water and a plastic bad in order to locate and identify freshwater organisms.  The activity is designed for younger grades, but...

Field study groups collect samples of stream water and identify the macroinvertebrates found. Using their data, they calculate a water quality index to rate the health of the stream. They graph their data and discuss the value of a water...

Students use a light microscope to observe the organisms living in a sample of ocean or fresh water. Students create a drawing of the organisms that they observe. Students then discuss the different body plans of the organisms and the...

In collaborative groups, young ecologists measure the temperature, pH, and dissolved oxygen for three different freshwater samples. They examine each sample with a microscope and record observations on the microorganisms in the pond...

Students examine brackish water. In this Science instructional activity, students observe organisms found in brackish water. Students record their observations of the various organisms.

Students observe the effects of pollution on living organisms. In this pollution lesson plan, students observe fresh water Hydra and look at their structures and movement. They place samples of pond and lake water on the Hydra and...

Students identify and describe various organisms living in a pond water environment. They describe the characteristics of living things. Students compare and contrast organisms created by asexual reproduction and sexual reproduction....

Young scholars visit a local creek or stream. They collect water samples from the creek and observe and sort the "water critters" they find in the sample, observing smaller organisms under a microscope if necessary. They identify each...

Students study Arthropods and their characteristics.  In this organisms instructional activity students explore the success of Arthropods and answer questions. 

A food web consists of complex food chains and the more complex the web, the better likelihood of survival. Learners compare and contrast food webs and food chains and discuss concepts like the predator-prey and consumer-producer...

Students examine the structure, function, and characteristics of microscopic organisms that inhabit freshwater through collection of water samples and observation through microscopes.

Students explore what a food web is. In this science lesson, students examine how nutrients and other pollutants enter a lake and play a food web game whereby students pretend they are either zooplankton, planktivore,...

Fourth graders examine the islands of Hawaii. Using this information, they organize it and create a map or graph that represents the data. As a class, they discuss how the watersheds on the islands are different and how people react to...

Young scholars examine the water samples from a demonstration and discuss the difference between fresh and salt water. They draw different animals that live near or in the ocean and how humans can harm the ocean habitat. They draw...

Students explore oceanography by completing science worksheets. In this tide pools lesson plan, students discuss the forces of the tide pools, the animals that live within them, and the impact they have on the rest of the ocean. Students...

Young scholars work together to examine water quality. They identify the indicators of water quality and complete an experiment. They discuss their results.

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...

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...
