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)

Presents activities that use marine organisms with plant-like appearances to help students build classification skills and illustrate some of the less obvious differences between plants and animals. Compares mechanisms by which sessile plants and animals deal with common problems such as obtaining energy, defending themselves, successfully…

Describes a simple, relatively inexpensive laboratory activity that allows students to examine the requirements for the fungal decay of wood and devise methods for prevention. (ZWH)

Describes symbiosis and its significance in the day-to-day lives of plants and animals. Gives specific examples of mutualism, commensalism, and parasitism in the relationships among fungus and plant roots, animals and bacteria, birds and animals, fish, and predator and prey. (MDH)

An activity that can be used to teach plant nutrition and the use of hydroponics is presented. Materials and procedures are discussed. Possible topics for science projects are suggested. (CW)

Pollination vectors of a variety of types are described including beetles, bees, flies, moths, birds, bats, and the wind. Some of the adaptations of plants designed to help facilitate pollination are discussed. Strategies for incorporating this information into a lesson plan are suggested. (CW)

Describes an experiment to induce carbon dioxide deficiency to demonstrate its effects on plant growth. Suggests further studies to examine respiration by soil microbes and the effects of relative humidity, other gases, and air pollution on plant growth. (MDH)

Explains how the tobacco mosaic virus can be used to study virology. Presents facts about the virus, procedures to handle the virus in the laboratory, and four laboratory exercises involving the viruses' survival under inactivating conditions, dilution end point, filterability, and microscopy. (MDH)

Describes an easy and inexpensive method of preparing experimental growth media that high school students can use for plant cloning investigations. (PR)

Describes the four major phases of a science project to create a school-site native plant habitat: (1) planning the habitat area; (2) constructing the habitat; (3) writing the related curriculum; and (4) providing inservice programs to other interested science teachers. (MDH)
