Presents three activities using pearl onion bulbs to illustrate plant growth and plant propagation under various conditions. (WRM)

Presents several activities designed to teach students about the characteristics, classification, life cycle, and uses of the luffa (gourd). (WRM)

Enables students to examine the time course for seed imbibition and the pressure generated by imbibing seeds. Provides background information, detailed procedures, and ideas for further investigation. (DDR)

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)

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)

Presents an activity in which students use a discovery approach to learn about seed texture, similarities and differences among seeds, and which seeds grow on which trees. (MKR)

Uses diagrams and text to describe four activities involving trees designed to aid students in better understanding responses to seasonal changes (ZWH)

Describes a simple and inexpensive way to construct two small growth chambers for studying phototropism in the science classroom. One chamber is designed to illustrate how plants grow around obstacles to reach light and the other to illustrate directional light responses. (HM)

Classroom plant activities have long been inexpensive, easy to do, and fun for students, and have become more central to biology teaching. Introduces some plant science activities and their pleasures and pitfalls. (ASK)

Describes an ecology exercise suitable for secondary school students in which the school grounds may be used to study communities in association with woody plants. (JR)

Presents a science activity to help students to explore the concept of primary productivity by growing lawn grass in the classroom. (HM)

Describes an activity that reduces the biosphere to a water-filled jar to simulate the relationship between cellular respiration, photosynthesis, and energy. Allows students in high school biology and related courses to explore quantitatively cellular respiration and photosynthesis in almost any laboratory setting. (ASK)

Lists the Indian uses of sixty plants found in the Pipestone National Monument Aboretum in Minnesota. Suggests that similar arboretums be planted in schools to provide students with the opportunity of becoming familiar with these native plants and how they contributed to the lives of American Indians and early settlers.
