This site provides a detailed lesson plan to help students grasp the concepts of biotic and abiotic. Background information is provided for the teacher and plans are given for two days.

This fun quiz has you choose between different images to decide whether it is biotic or abiotic. It also gives examples through illustrations of abiotic and biotic things.

Find out how nitrogen is cycled throughout the biosphere as it passes through the nitrogen cycle. Learn about the biotic and abiotic factors involved in the process as well as the implications of human activity on the nitrogen cycle.

Learn about the biotic and abiotic factors of lakes and ponds as well as learning how lakes form through reading and video clips.

Students analyze and explore visualizations and graphs that show the annual cycle of plant growth and decline. They investigate several regions in each hemisphere that have different land cover and will match graphs that show annual...

Students will conduct a field investigation to learn about the environment. They will observe biotic and abiotic factors of an ecosystem. Students can use the CBL 2 and a temperature probe to collect data and a graphing calculator to...

The abundance and distribution of organisms in an ecosystem is determined by biotic and abiotic factors. Animals and plants have adaptations to allow them to compete for resources.

A suite of lessons focusing on the process of upwelling. Inquiry-based exploration of seasonal upwelling includes marine food webs, food production in the ocean, wind-driven ocean currents, and seasonal changes in biotic and abiotic...

In this lesson learners analyze videos to make observations about species, populations, and communities of organisms and discuss their symbiotic relationships. Then they create a hypothetical marine ecosystem and describe the adaptive,...

Find out why creating and conserving habitat for amphibians and reptiles is important.

Students explore the differences between living and nonliving things through the lens of the nursery rhyme, "Hey Diddle Diddle." After bringing the characters to life, the students discuss the concepts of living and nonliving and act out...

Students conduct experiments to determine what environmental factors favor decomposition by soil microbes. They use chunks of carrots for the materials to be decomposed, and their experiments are carried out in plastic bags filled with...

Work samples, phenomena, assessment templates, and videos that directly address standard 3-LS3-2: environmental influence on traits.

In this unit, learners will try to improve stream quality and reduce human impacts by taking action.This Advanced Water Quality unit is packaged into three smaller parts: Part 1: Stream Habitat Assessment; Part 2: Macroinvertebrate...

See how organisms each have their own role in the ecosystem.

This field trip is designed to physically immerse learners in the concept of habitat alteration focusing on biotic and abiotic habitat alterations.

A video and a short multiple-choice quiz on the topic of ecosystems, covering biotic and abiotic factors, and the roles organisms play in an ecosystem.

A webpage giving an overview of ecology. Learn about the biotic and abiotic factors that make up an ecosystem as well as the different levels of ecology.

Explains what an abiotic factor is, and discusses each of six types and their roles in ecosystems and habitats. (Published: July 31, 2010)

[Free Registration/Login may be required to access all resource tools.] In this module, students will learn about the cycles of nature (water, carbon, nitrogen, and phosphorus) that support the flow of nutrient matter through an...

This NY Regents prep site provides a nice overview of what abiotic and biotic factors of an ecosystem are, as well as a brief description of carrying capacity.

This tutorial explores abiotic and biotic factors with videos and interactive activities.

After looking at examples of biotic and abiotic factors in ecosystems, students focus on abiotic factors in marine ecosystems, the physical processes that are involved, and the impact human activities can have on these. Includes handouts...

Abiotic components are the nonliving components of the biosphere. Chemical and geological factors, such as rocks and minerals, and physical factors, such as temperature and weather, are referred to as abiotic components.
