The Water Cycle
An inventive and interesting lesson on the water cycle (and other cycles associated with it), is here for you. After doing a well-designed hands-on inquiry in class, learners also identify organisms and processes that are involved in the...
Curated OER
The Water Cycle
Fifth graders identify organisms and processes involved in three cycles: the water cycle, the carbon cycle, and the nitrogen cycle. They produce a pictorial or abstract water cycle, and appropriately place life forms onto an existing...
Curated OER
The Hydrologic (Water) Cycle
Learners construct a model of the hydrologic cycle, and observe that water is an element of a cycle in the natural environment. They explain how the hydrologic cycle works and why it is important, and compare the hydrologic cycle to...
Curated OER
The Water Cycle
Fifth graders explore the major components of the water cycle. They pay close attention to evaporation, condensation, and precipitation. A water cycle kit is set up in the classroom, which learners observe for a couple of days before the...
Curated OER
What Goes Around Comes Around!
Students create an ecosystem in a jar to show a model of the water, carbon, and nitrogen cycle. Working in small groups, they research and present orally the information they find on this cycle.
Curated OER
Moebius Strips
Students make Moebius strips and use them to demonstrate the interconnectedness of an environment. They explore the natural cycles (water, oxygen/carbon dioxide, carbon, nitrogen) within the environment. They describe how the cycles are...
Curated OER
The Nutrient Cycles
Students investigate the circle of sea life by creating nitrogen compound models. For this oceanography lesson, students discuss sea creatures and where their waste goes. Students identify nitrogen cycles in the ocean by...
Curated OER
The Water Cycle
Fifth graders investigate evaporation, condensation, and precipitation. They observe a water cycle kit and record their observations, and examine how water condenses on the outside of a cup. Next, they observe an evaporation...
Curated OER
Microbial Influence on Earth's Systems
Learners identify the different biogeochemical cycles on Earth. In this biology lesson, students observe microbes under a microscope. They compare and contrast respiration and photosynthesis.
Curated OER
The Water Cycle
Fifth graders examine the stages of the continuous water cycle that exists on Earth. They observe a water cycle model that is set up in the classroom and write descriptions of what they see. As a class, they discuss models of the water...
Curated OER
Weathering
Second graders explore weathering and how the water cycle plays a part in weathering. In this weathering lesson, 2nd graders put gravel and sugar cubes in a jar and shake, simulating weathering. Students use the scientific method to...
Curated OER
Daily and Seasonal Cycles
First graders identify the sun as a source of heat and light. They identify features of houses that help keep use sheltered and comfortable throughout daily and seasonal cycles. Students are told that summer is the best season to...
Curated OER
Trophic Relationships, Cycling of Chemicals, Human Impact on Ecosystems and Conservation
Students explore how the energy flow through a system is related to trophic levels. They investigate how organisms affect the cycling of elements and water through the biosphere. Students participate in lab activities to observe ways...
Curated OER
Rosa Parks Community Garden
Students explore gardening and nutrition in the Rosa Parks Community Garden. They work in stations to discuss food choices, the life cycles of plants, and mini-composting. After starting in one station, they rotate to try each activity.
Curated OER
Recyclers Revisited
Fifth graders observe their plant experiments that they started in a previous lesson and examine the role of decomposers in the nitrogen cycle. Two weeks after they set up a worm terrarium, they analyze any changes they observe, and...
Curated OER
Composting
Using 2-liter bottles, junior ecologists create composting tubes in which they place nitrogen-rich and carbon-rich materials. They observe what changes occur over two weeks' time. Provide more specific direction to your class as to what...
Curated OER
Microbes in Long Island Sound
Students discover the harm and benefits of microbes. In this biology lesson, students explore water, nitrogen and carbon cycles. They investigate the factors affecting bacteria growth.
Curated OER
Physical and Chemical Changes
Sixth graders complete several experiments about chemical and physical changes. In this physical and chemical science lesson, 6th graders complete 6 experiments about chemical and physical changes. Students examine the processes of...
Curated OER
Ions in the Environment
Students explain the importance of the five main biogeochemical cycles. In this chemistry lesson, students discuss how ions are transported in the environment. They design an experiment to collect data on eutrophication.
Curated OER
Solid Waste Recycling
Students seek scientific and technological solutions to envrionmental problems. They record class activities in a journal. They identify relationships among living things and their environments.
Curated OER
Food Chains
Learners take a look at the relationship between organisms in food chains, food webs, and energy pyramids. After an opening demonstration by the teacher, pupils are split up into groups. Each one is assigned an environment such as:...
Curated OER
Biological Sciences
Students examine biodiversity and interrelatedness concepts. In this ecology activity students go on a field trip and fill out a data sheet.
Curated OER
Water Retention and Soil Variation in Local Ecosystems
Students identify the differences in local soil types and the relationship between soil size and water retention. They are introduced to microenvironmental conditions in ecosystem sustainability.
Curated OER
What We As Students Can Do To Save Our World
Students investigate air and water pollution, and the conservation of natural resources.
