Curated OER
The Dose makes the Poison
Students investigate the effect of a chemical (they choose) on the germination of seeds. They calculate % chemical concentrations in water, form a hypothesis, and discuss the ethics of using animals in biomedical research.
Curated OER
POLLINATION DEMONSTRATION
Third graders study the terms pollen and pollination. They use appropriate vocabulary in describing their investigations, explorations, and observations (e.g., stem, pistil, stamen, flower). They describe, using their observations,...
Curated OER
Nitrogen Fixation, OR What a Gas!
Students illustrate the adaptation and co-evolution of organisms. They examine set up an experiment to determine the effect of adding the Rhizobium bacteria to a group of legume seeds.
Curated OER
Mr. and Mrs. Cress Head
Students explore Earth science by completing a plant art project. In this botany lesson, students utilize tights and soil to create a furry, grassy puppet style animal from cress seeds. Students cut off the excess cress after several...
Curated OER
Sunlight and Plants
Students design and conduct an experiment to discover the role of direct sunlight on plants during germination and after germination. They plant corn and lima beans in small containers which they place in direct sunlight from a window...
Curated OER
Light Plants and Dark Plants, Wet Plants and Dry Ones
Learners plant sunflower seeds in plastic cups, and once germinated, these are exposed to different conditions of light levels and/or soil moisture contents. Students measure growth of the seedlings every few days using non-standard...
Curated OER
Investigating Monocots and Dicots
Students know about monocotyledons and dicotyledons. They explore the differences between the seed structure of the two by examining bean and corn seeds. They sprout seed to observe the differences in both of their growths.
Curated OER
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
Growing Barley and Detecting the Presence of Amino Acids
Students produce the greatest mass of plant material possible for 100 seeds of barley, and detect amino acids in barley plant material. They develop rules for the investigation, conduct the experiment, and prepare a computer spreadsheet...
Curated OER
Life Cycle of Trees
For this Life Cycle of Trees worksheet, students read one page about the life cycle of a trees. Students define 12 terms from the reading.
Curated OER
Using the Scientific Method to Determine Which Conditions Best Favor Plant Growth
Seventh graders examine how the environment can affect biological processes. They identify the best conditions for the germination of bean seeds. They record and analyze their data. They write about their observations in an essay.
Curated OER
How Does it Affect Plants?
Students 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
Students observe the effects of acid rain on plants through experimentation and research. Students research types of crops in their area. Students 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. For this hereditary traits lesson, 6th graders discuss similarities and differences in corn and complete charts for their discussion. Students then use a dent corn...
Curated OER
Cotton and Cabbage
Students 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 had a...
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
Pupils 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, and...
