Describes activities on two storage organs, carrots and radishes, which are plants that store some of the food their leaves make in modified roots, stems, and even leaves. (ASK)

This paper explores the different types and characteristics of preschool children's explanations of plant growth and rain formation. The children's explanations were categorized as naturalistic, non-naturalistic, or synthetic, i.e., explanations containing both naturalistic and non-naturalistic parts. In regards to plant growth the children…

Presents a number of simple exercises that demonstrate potato tuber characteristics and are designed for high school biology students and teachers. Exercises include Typing, Grading, Shape, Eye Characteristics, Defects, Specific Gravity, Dry Matter Content, Glucose Content, Baking, Frying/Chipping, and Taste Testing. (JRH)

Presents an activity that involves using sponge seedlings to demonstrate the germination process without the usual waiting period. Discusses epigeous versus hypogeous germination, and cotyledon number and biodiversity. (JRH)

This activity involves elementary students in an investigation of the usefulness of plant parts as a food source. An introduction discusses the dependence of animal life on plants. Materials needed and step-by-step procedure are provided. (LZ)

Uses diagrams to aid in describing a simple, rapid technique for staining the nuclei of pollen grains that have been germinated in vitro. (ZWH)

Amber is the fossilized resin of now-extinct trees, primarily ancient conifers but also some flowering tropical trees. An aromatic, soft, sticky substance, resin in extinct trees probably served the same purposes as resin in modern trees: to protect the plant by sealing cuts and by excluding bacteria, fungi, and insects.

Teaching plant growth to seventh-grade life science students has been interesting for the author because she grew up in a rural area and always had to help in the garden. She made many assumptions about what her rural and suburban students knew. One year she decided to have them grow plants to observe the roots, stems, leaves, flowers, and fruit…

The exciting world of plants may be something of a mystery to many children, and the often-dry content of a curriculum taught indoors inhibits real understanding of many complex biological processes. Moving outdoors opens up an unexplored world and presents rich opportunities for imaginative learning. The "Life processes and living…

This paper describes how second/third year undergraduates with little prior botanical knowledge, attending a one-week field course in Western Scotland, were enabled to complete within one day an intensive phytosociological exercise. They showed that two stands of heathland vegetation were objectively different through identification of plants,…

This guide contains indoor and outdoor gardening activities for children. The activities teach children how plants live and grow; how the weather, temperature, and seasons affect all living things; how living things come out of seeds and soil; how the birds, earthworms, bees, and toads help in the garden; and how the whole environment works…

Presents a project that allows students to observe and show how quickly pollutants in the air and on the ground destroy plant life. Appropriate for grades four through six. (JRH)

Describes an alternative to studying plant community composition and dynamics. Suggests that teachers and students collect soil samples containing buried seeds (the seed bank), germinate the seeds in the laboratory, and analyze community dynamics through the composition of the seed bank. (ZWH)

Finds that many restoration projects have attempted to replace the native species, but project planners often have an imperfect understanding of the plant communities they are trying to re-create. Argues that when students join these projects, they may receive an inaccurate impression of local ecosystems. (Author/CCM)

Living things respond to a stimulus, which is a change in the surroundings. Some common stimuli are noises, smells, and things the people see or feel, such as a change in temperature. Animals often respond to a stimulus by moving. Because plants can't move around in the same way animals do, plants have to respond in a different way. Plants can…
