Sun Seeking Plants
Students investigate the story "The Tiny Seed" by Eric Carle. This story is used to introduce the children to the concept that seeds change and grow into plants when conditions in the environment including temperature, light, water and...
Curated OER
Earth Surface Socratic Questions
Students explore the ways Earth's surface is shaped by hydrologic, climate and tectonic forces by participating in a whole class discussion. They respond to prompts that lead them to conclusions about the relationships between landforms...
Curated OER
Building an Ecologically Balanced Living Space
Students design and build an ecologically balanced living space based on the principles of an old growth forest. They take one part of a house (or structure in the community) and redesign it according to the principles of the forest cycle.
Curated OER
Selecting Soil Organisms in Compost
Students demonstrate that many of the enzyme systems needed to break down--and therefore clean up-society's wastes already exist in nature among the decomposers. They select the best starch-munching organisms by altering the environment...
Curated OER
Plant Biotechnology: Controlling Tissue Differentiation
Learners demonstrate hormonal control of plant tissue differentiation and relate this differentiation to gene expression. They explore the effects of hormones (auxin and cytokinin) on the genes that control tissue differentiation in callus.
Curated OER
Multiplying Microbes
Ninth graders investigate the techniques of culturing bacteria. They culture bacteria using agar plates. Students identify and describe some environmental conditions that effect bacteria growth.
Curated OER
Dirty Decomposers
Seventh graders design and conduct experiments to determine what environmental factors favor decomposition by soil microbes. They use chunks of carrot for the materials to be decomposed, and their experiments are carried out in plastic...
Curated OER
Viruses, Bacteria, Protists, and Fungi
In this viruses, bacteria, protists, and fungi activity, students will review the basic characteristics of each of these groups. Students will complete 7 fill in the blank questions about viruses, 6 true or false questions about...
Curated OER
The Diversity of Fungi
In this fungi worksheet, students will review the growth and reproduction of zygomycetes and the characteristics of ascomycotes, basidiomycotes, and deuteromycotes. This worksheet has 15 fill in the blank, 4 short answer, and 8 matching...
Curated OER
Toward a Sustainable Agriculture
Students analyze organic production systems. In this organic agriculture lesson, students examine key organic practices for both crop and livestock. This lesson includes 5 different activities, 4 critical thinking questions and...
Curated OER
Nitrogen Fixation, OR What a Gas!
Students gain skill in the design, implementation, and reporting of a scientific research project using the scientific method. They set up an experiment to determine the effect of adding the Rhizobium bacteria to one group of legume...
Curated OER
Testing Your Water
Students perform several water quality tests on groundwater from their area. They use test strips to determine the pH, hardness, alkalinity, nitrates, iron and chloride levels.
Curated OER
Selecting Soil Organisms in Compost
Students conduct an experiment to demonstrate that many of the enzyme systems needed to break down society's wastes exist in nature among the decomposers in a compost pile. They culture compost bacteria on starch agar to examine the...
Curated OER
Project Wetlands
Learners develop a joint undertaking designed to solve an environmental problem in their local community. They tackle the problem of erosion of banks and chemical run-off into a nearby lake, which is within walking distance of school.
Curated OER
Field Crops in the Agro-ecosystem
Ninth graders explore how to apply ecological analysis to cropping systems. In this agro-ecosystem lesson students study management practices including soil and fertility.
Curated OER
Water Retention and Soil Variation in Local Ecosystems
Students identify the differences in local soil types and the relationship between soil size and water retention. They are introduced to microenvironmental conditions in ecosystem sustainability.
Curated OER
The Global Impact of Insect Borne Diseases & Agriculture
Pupils study the global impact of insect borne diseases, the appropriate use of pesticides, and the concept of human interrelations on a world wide scale. They examine how to safely apply a pesticide, according to the label.
Curated OER
Plant Biotechnology: Controlling Tissue Differentation
Learners demonstrate skills of biotechnology stringent aseptic technique and statistical analysis. They describe hormonal control of plant tissue differentiation and relate this to gene expression. Students observe the effects of...
