Lesson 5 & 6: "The Study of Ecological Relationships and Populations"

Learners use litmus paper to begin to discover the qualities of acids and bases. They learn about pH by testing clear liquids for acidity with purple cabbage juice as an indicator. The video Streamkeeper, with Bill Nye, and other video...

Learners examine bioluminescence and camouflage of deep sea creatures. In this deep sea creatures lesson plan, students investigate the visible and near-visible light spectrum. They work in small groups to complete a light, color, and...

Students identify and describe rocks that contain records of the earth's history and explain how they were formed. They formulate questions about and identify needs and problems related to objects and events in the environment, and...

Learners explore food chains. In this ecosystem activity, students discover how plants and animals rely on each other for survival. Learners research the rocky shore ecosystem and create a skit representing the ecosystem.

Students complete a pre-test on the relationship between heredity and the environment. As a class, they write down descriptions of themselves and identify which traits can be changed and not changed. In groups, they determine which...

Students explore the relationship between leaf packs in streams and macroinvertebrate populations. They experiment with hand exposure to stream macroinvertebrates in natural leaf packs and then make leaf packs of their own. The...

Wolong Nature Reserve is a place of great biodiversity and varied environments located in Western China. The reserve's history is described. Various human ethnic and cultural groups are explored as well as the extensive giant and red...

Students study the interdependence of an ecosystem that allows it to sustain itself. They examine the Western lowland gorillas for an example.

Learners explain the relationship of plants and animals in the environment. They name the basic requirements for plant growth and define the terms photosynthesis, stomata, chlorophyll and xylem.

In this ecology worksheet, students will fill in a graphic organizer showing the relationship organisms have with their environments and with each other. This includes biotic and abiotic factors, tropic levels, and ecological pyramids....
