Biomes and Dandelions Overview

8th Grade

Students will recognize biotic and abiotic words, complete a lab to explore different types of soils using the naked eye and microscope, and create a drawing of the nitrogen cycle. They will conclude with an extensive research project that includes making a food web poster and a diorama/3-D model about the dandelion biome.

Lesson Objectives

  • Students will classify the organisms within an ecosystem according to the function they serve: producers, consumers, or decomposers (biotic factors).
  • Students will explain why producers (such as dandelions) and decomposers (such as fungi and bacteria) are important to the survival of ecosystems.
  • Students will discover and report on the flow of energy within food webs. They will use appropriate methods (charts, graphs, etc.) to share the relevant data.
  • Students will summarize how abiotic factors such as temperature, water, sunlight and soil quality in biomes affect an organism’s ability to survive.
  • Students will explain how the flow of energy within food webs is interconnected with the cycling of matter (including water, nitrogen, carbon dioxide and oxygen).

Curriculum Alignment

NC Essential Standards

  • 8.L.3 Understand how organisms interact with and respond to the biotic and abiotic components of their environment.
  • 8.L.3.1 Explain how factors such as food, water, shelter and space affect populations in an ecosystem.
  • 8.L.3.2 Summarize the relationships among producers, consumers, and decomposers including the positive and negative consequences of such interactions including:
    • Coexistence and cooperation
    • Competition (predator/prey)
    • Parasitism
    • Mutualism
  • 8.L.3.3 Explain how the flow of energy within food webs is interconnected with the cycling of matter (including water, nitrogen, carbon dioxide and oxygen).
  • 8.V.3 Create art using a variety of tools, media, and processes, safely and appropriately.
  • 8.TT.1 Use technology and other resources for assigned tasks.
  • 8.RP.1 Apply a research process to complete project-based activities.
  • 8.SE.1 Apply responsible behaviors when using information and technology resources.

Next Generation Science Standards

  • MS-LS1-6 Construct a scientific explanation based on evidence for the role of photosynthesis in the cycling of matter and flow of energy into and out of organisms.
  • MS-LS2-1 Analyze and interpret data to provide evidence for the effects of resource availability on organisms and populations of organisms in an ecosystem.
  • MS-LS2-2 Construct an explanation that predicts patterns of interactions among organisms across multiple ecosystems.
  • MS-LS2-3 Develop a model to describe the cycling of matter and flow of energy among living and nonliving parts of an ecosystem.
  • MS-LS2-4 Construct an argument supported by empirical evidence that changes to physical and biological components of an ecosystem affect populations.

Common Core
