Sixth graders work together to complete an experiment about the quality of freshwater. In groups, they collect fresh water samples from a variety of sources and test the pH levels. After completing a KWL chart, they test the amout of...

Students investigate the many varieties of both tropical and freshwater fish, and find out about the anatomy of these creatures. They explore biodiversity in bodies of water, including information about coral reefs, and study the effects...

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...

Learners work together to build their own fish ecosystems. As a class, they share their prior knowledge about catfish and use a diagram to label its body parts. They record their observations of the ecosystem and determine what they...

Students design an experiment to evaluate the effects of various treatments on the nitrogen cycle in a freshwater aquarium. They are required to maintain a laboratory notebook of all work, measure the key analytes of the biosystem at...

Students conduct an experiment with potato cores and a sucrose solution to investigate how salt water fish process water. They develop a lab report of their experiment.

Learners explore the environmental factors that influence where fish live and determine the makeup of fish communities in the Hudson. They interpret guided observations and measurements to assess patterns, sequences and relationships.

Students use tables of fish collection data to draw conclusions about where fish live in the Hudson Estuary. Given available data they interpret organized observations and measurements and recognize simple patterns, sequences, and...

Students explore biology by conducting a freshwater fishing activity. In this crawdad lesson, students discuss what a crawdad is, where they are found and how they can be prepared as a meal. Students utilize string, alligator clips,...

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,...

Students analyze and record major events that occur in the development of Medaka fish eggs from fertilization to hatching. In small group, students describe the processes involved, creating a timeline of the major events in the...

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

Your young apprentices build a function describing the percent concentration of salt in a brine. The rational function is then related to the parent function, y= 1/x, and graphed. Finally, the apprentices predict the amount of fresh...

Students investigate the presence of specific organisms in a freshwater habitat to determine the quality of that habitat. They conduct a field study and distinguish and classify organisms found during the field study.

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....

Fourth graders study and identify the basic needs of a variety of organisms. Terrariums and aquariums are used to demonstrate what plants, animals, and fish need to stay alive. These two classic models are used to effectively convey what...

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 explore food chains and food webs in a pond and identify common creatures found in ponds. They look for tadpoles, fish, mites and other creatures in a pond during a field trip for first hand research.

Students explore techniques used to filter water and different pollutants. In this prevention of water pollution lesson plan, students define water pollution and list ways water is polluted. They explore water purification and complete a...

Students discuss places they have been where the air seemed hard to breathe. They discuss if they could "see" the humidity or smell. Students discuss ways this might relate to the fish in the aquarium. The teacher introduces pH and how...

Young scholars 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...

Learners explore the freshwater ecosystem of Africa's Lake Victoria by creating a freshwater aquarium. They investigate factors affecting the aquarium's ecosystem and conduct lab activities.

Second graders identify saltwater and freshwater habitats and the resources found in them. They compare and contrast the two habitats and discuss their findings. They discover the resources bodies of water can provide.

First graders recognize that nearly three quarters of the Earth is covered by ocean. They locate the Pacific, Atlantic, Indian, Arctic and Antarctic oceans on a map. They describe the difference between ocean water and fresh water.
