Students describe the effects of biological magnification on ecosystems. This lesson focuses on biomagnification as it relates to the ecosystems of the Great Lakes region in the mid-western United States.
Ecology scholars consider the processes of bioaccumulation and biomagnification in the environment. As an example, DDT bioaccumulates in the fatty tissue of animals, resulting in reproductive failure and nervous system damage. DDE accumulates at in increasing amounts in animals higher on the food chain in the process called biomagnification. A few slides in the middle of the presentation review food webs, a concept vital to understanding these unfortunate consequences of using pesticides.
Your biology class plays the role of epidemiologist when a mysterious illness breaks out in Kildare, USA. Using interviews with doctors, patients, and local citizens, maps, the results from different materials sampling, they work to discover the cause of the disease. There are financial costs to be considered. A solution is proposed.
Sixth graders explore the food chain by researching bald eagle diets. In this animal poisons instructional activity, 6th graders identify the chemicals that fish eat which are later consumed by bald eagles. Students utilize colored paper and coloring utensils to conduct an aquatic plant demonstration.
In an ecology simulation, middle schoolers draw dots, representing chemicals, on green strips of paper, representing aquatic plants. After you hide the strips around the room, they pretend to be fish and collect plants as food. The total chemical dots are tabulated and transferred to orange strips, representing fish. Finally, after fish strips are hidden, learners pretend to be eagles and collect fish as food. The total chemical dots are again tabulated and the effects of biomagnificaiton demonstrated. Extension and assessment activities are suggested within the plan.
Students use real data to create an algebraic equation. They explain how the build up of small levels of contaminates can quickly become detrimental to species higher in the food chain.
Students explore the differnences between food producers in food webs and food consumers in food chains. Behavioral choices of primary and secondary consumers such as herbivores, vegetarians, carnivors, and omnivors are analyzed.
For this heat worksheet, students determine the heat gained or lost when matter changes phases. Students review the energy flow through ecosystems by comparing trophic levels and food webs. This worksheet has 10 fill in the blank, 5 short answer, and 2 problem solving questions.
Students explore the dangers of eating high levels of mercury and how small amounts of mercury in water accumulate in greater quantities in organisms higher in the food chain. They list the health of effects of high levels of mercury on humans.
What a terrific way to explore the pond habitat! Learners discuss the animal and plant life found in the Long Island area. They also discuss vocabulary terms, identify pollution concerns, and resource conservation.
Second graders examine how food chains interact with different plants and animals. They practice using new vocabulary. They also discover the role of pesticides in the environment.
Students review the basic concepts of the food chain. In small groups, they research an organism and create a food web. In addition, they study biomagnifications and write a brief essay or make a poster informing others about the dangers of biomagnifications of pollutants.
In this food web design worksheet, students sketch and create an illustration of a food web of a chosen habitat area. Students label the types of feeders and use correctly oriented arrows to show the feeding relationships to show the flow of energy through the system.
The first half of this thought-provoking presentation introduces viewers to some of the ways humans are impacting the environment: climate change, acid rain, and intensive farming. The second half suggests ways to minimize that impact. Photographs and real-life examples are included. Use this as an introduction to an environmental studies unit with upper elementary or middle schoolers. Perhaps you might assign groups to research which of the suggested alternatives is being practiced locally.
Can insects act as sentinels for our environment? Prior to viewing the video, review different roles that insects are known to play and discuss the concepts of bioaccumulation and biomagnification. Show the video about how insects gather information about their surroundings and how scientists can analyze their DNA to learn from it. Finally, assign your class to use an energy pyramid to calculate bioaccumulation of a toxic material. This would be ideal enrichment for your environmental studies or ecology unit when covering food chains and trophic levels.
Students investigate estuaries and the variations in physical factors from one estuary to another. In this estuaries lesson plan, students explore water depth, salinity, temperature, and dissolved oxygen in estuaries using an on line tutorial and make inferences about their relationships. Students use an on line database to gather information about the estuaries and they analyze the data. Students complete an 88 question self test and 2 puzzles.
Students examine how physical factors in estuaries vary over time. They conduct Internet research, take an online quiz, analyze a database, and complete a worksheet.
Students retrieve and interpret data on the distribution of selected estuarine animals at various stages in their life history. They compare the distribution of selected species in two or more estuaries and draw inferences about the ecology of the estuaries.
Students investigate the social, economic and environmental consequences that might result from Arctic climate change. Students identify and discuss at least three consequences.
Students demonstrate how chemicals accumulate in fish fat. They study path ways of toxins in the fish's body and ways to prepare fish to avoid consuming the toxins. They examine U.S. and Canada regulations to protect the environment.
