THE LIVING EARTH WORKSHEET ANSWERS KEY FULL

But individuals and communities are doing things to help protect Earth’s resources and environments.

Human activities have had major effects on the land, vegetation, streams, ocean, and air.

Matter cycles between the air and soil and among plants, animals, and microbes as these organisms live and die.

LS2.B: Cycles of Matter and Energy Transfer in Ecosystems.

A healthy ecosystem is one in which multiple species are able to meet their needs, and newly introduced species can damage the balanceof an ecosystem. Organisms called decomposers break down dead organisms, recycling some materials back into the soil.

The food of almost any kind of animals can be traced back to plants.

LS2.A: Interdependence Relationships in Ecosystems.Living things affect the physical characteristics of their regions.Populations live in a variety of habitats, and change in those habitats affects the organisms living there.For any particular environment, some kinds of organisms survive well, some survive less well, and some cannot survive at all.Here we list the scientific ideas that shine through in Habitat Earth.

Remember that this will affect the specific learning outcome for your students don't aim to use all three!ĭepending on your grade level and subject matter, your expected use of the full film will undoubtedly differ from other K-12 teachers. Need a list of simple techniques to encourage active viewing of media, or to encourage group sharing?Ĭonsider using one of the below as a lens through which to explore content featured in the full film.

How Stable is Your Food Web? (Grades 5-8).

Kinesthetic Astronomy: Longer Days, Shorter Nights (Grades 3-8).

Lesson that use video clips in this way include: Videos often tell stories that reiterate or reframe science concepts your students are mastering through active, hands-on lessons.

Using Empirical Data in the Classroom: Raptor Migrations! (Grades 6-11).

Photosynthesis Seen From Space (Grades 6-10).

Lessons that use video clips in this way include:

Visualizations based on aggregated data provide the unique opportunity to engage your students in various Science Practices highlighted in the Next Generation Science Standards, including asking questions, analyzing and interpreting data, and constructing explanations.

From Farms to Phytoplankton (Grade 6-11).

Planes, Trains, or Bicycles: Being a Low-impact Traveler (Grades 6-10).

Lessons that use video clips in this way include: Videos can activate prior knowledge, engage the student with something mysterious or visually appealing, or establish a purpose for learning. This picture shows the levels of organization in nature, from the individual organism to the biosphere.Media can serve as a 'hook' that opens up the lesson. The biosphere consists of many different biomes.

The biosphere is the part of Earth where all life exists, including all the land, water, and air where living things can be found.

A group of similar ecosystems with the same general type of physical environment is called a biome.

The nonliving environment includes water, sunlight, soil, and other physical factors.

An ecosystem consists of all the living things ( biotic factors) in a given area, together with the nonliving environment ( abiotic factors).

The community that includes the goldfish population also includes the populations of other fish, coral, and other organisms.

All of the populations that live in the same area make up a community.

For example, all of the goldfish living in the same area make up a goldfish population.

Organisms of the same species that live in the same area make up a population.

These levels are illustrated in Figure below. There are also levels of organization above the individual organism. Each type of tissue is made up of cells of the same type. The stomach, in turn, consists of different types of tissues. One of the organs of the digestive system is the stomach. The system shown here is the digestive system, which breaks down food into a form that cells can use.

Organism: Individual living thing that may be made up of one or more organ systems.Įxamples of these levels of organization are shown in Figure below.Īn individual mouse is made up of several organ systems.

Examples of organ systems in a human include the skeletal, nervous, and reproductive systems.

Organ system: Group of organs that work together to perform a certain function.

Plant organs include roots, stems, and leaves. Human organs include the brain, stomach, kidney, and liver. The tissues of an organ work together to perfume a specific function.

Organ: Structure composed of one or more types of tissues.

Tissue: Group of cells of the same kind.Cell: Basic unit of structure and function of all living things.For example, many individual organisms can be organized into the following levels: The living world can be organized into different levels.
