How Does it Affect Plants?
Middle schoolers examine the effects of acid rain on plants. They observe the growth of seeds and the health of different plants for a month. They share their findings with the community.
Curated OER
Effect of Acid Rain on Plants
Learners observe the effects of acid rain on plants through experimentation and research. Students research types of crops in their area. Learners work in small groups to complete the experiments given, as well as write a report and...
Curated OER
We are where and what we eat
Students explore concepts of plants they eat, where and how they grow and are introduced to genetic diversity. They examine seed characteristics, look at their different sizes, shapes and germination time. They also set up seeds to...
Curated OER
Land Use Issues
Students discover seeds are a source of life. They also label the parts of a seed and examine the conditions which are needed for the seed to start growing. They follow the life cycle of seeds.
Curated OER
Natural Selection
Young scholars observe, measure and record variations that may be due to genetic inheritance. They look at the length of seeds for germinating pinto and lima beans and measure the distance between eyes in humans. They graph and discuss...
Curated OER
Our Changing Environment-- A Demonstration
Students observe and describe changes in an environment when some of the components are changed. They recognize the process of succession by
preparing a miniaturized environment in which a variety of plants and seeds are grown.
Curated OER
Living Corn Necklace
Sixth graders complete an experiment to learn about hereditary traits. In this hereditary traits instructional activity, 6th graders discuss similarities and differences in corn and complete charts for their discussion. Students then use...
Curated OER
Cotton and Cabbage
High schoolers note how given traits could be achieved by selective breeding and by transgenesis. They identify different uses of GEO. Students recognize that the use of letters (Bt) before an organism's name means that the organism has...
Curated OER
Creating the Water Cycle
Students create a terrarium to examine the stages of the water cycle. In small groups, they plant and water a seed in an enclosed plastic container. Each day they diagram and write observations of the terrarium using water cycle vocabulary.
Curated OER
Let it Grow, Let it Grow, Let it Grow
Students investigate, through a hands-on activity, in which type of soil a bean seed grows best. They create a bar graph representing each plant's growth in different soils.
Curated OER
Living Corn Necklace
Fifth graders explore heredity and observable traits through experimentation. They view several different types of corn and record their observation of physical traits on a class chart. They create a corn necklace by sprouting dried...
Curated OER
Life cycles
Students identify and explain the parts of a flower and their role in the life cycle of flowering plants, including pollination, seed dispersal, and germination. Students recap the following information: that plants need light, warmth,...
Curated OER
Name That Leaf
Take a walk through nature with a science experiment about leaves. Third graders use a branching diagram to group attributes of certain kinds of leaves, such as oak, pine, and chestnut. For extra practice, they can collect leaves and...
Curated OER
Know your roots!
Looking at an image of plant systems with their roots in the ground, learners determine which would be the most or least difficult to pull. They write short sentences describing which plant they chose and why. Intended for 3rd or 4th...
Curated OER
Native Beauty
Students plant wild flowers and maintain their garden. In this wild flowers lesson plan, students pick and prepare a gardening site, plant wild flowers, and maintain it everyday.
Curated OER
Plant Growth
Examine the growth regions and tissues in plants. The structures and specialized areas of roots, stems, and shoots are defined and supported with diagrams and pictures. Your class will also learn the details of specific growth hormones.
Curated OER
Fertilizers, Pesticides and Human Health
Students define several vocabulary terms related to chemicals and toxicology. Students calculate chemical concentrations in water and explain the toxicological principles that govern safety of substances. Students conduct an...
Curated OER
Do Plants Need Water?
First graders observe the effects of varying amounts of water, sun, and air on lima bean plants. They also predict and describe their outcomes in a written report.
Curated OER
Toxicology And Human Health
High schoolers examine the clinical effects of environmental toxicants on living organisms by collecting and analyzing scientific data and identifying ways of detection and diagnosis.
Curated OER
The Dose Makes The Poison
Students observe beakers of water that contain different amounts of a mystery chemical. They discuss how each amount of the chemical might affect them if the chemical was beneficial or harmful to their bodies.
Curated OER
Plant Hormones
Students identify different plant hormones and explain their function in plant development. In this biology lesson, students investigate how IAA affect root growth. They study the history of auxin discovery.
