This integrated STEM activity on the design of a vertical farming system has biology as the lead discipline and relates to the concept of photosynthesis. Students investigated the optimal design of vertical farms that will deliver appropriate amounts of water, sunlight and carbon dioxide to plants such that there will be optimal yield. Through…

Herbivores are important to ecosystems because they transfer energy stored in plant matter to other organisms. However, when herbivores occur in high abundances, they can become pests and harm the plants that form the basis of food webs. Mangroves are saltwater tolerant trees found along most tropical and subtropical shorelines. Because mangroves…

Where does our food come from? Such a question may be difficult for some children to answer, especially those living in a city apartment devoid of a backyard with a vegie patch or fruit trees. This article describes a learning experience designed to encourage Year 1 children to think about the foods that humans obtain from plants. The learning…

Taking objects apart including old electronics, product packing, and living plants, helps children understand how things work. Documenting this "unbuilding" or "deconstructing" encourages children to first consider the entire object, then the parts, and finally, the purpose of the parts. This article provides a lesson based on…

In this article, Claas Wegner, Phillip Weber, and Stephanie Ohlberger share how they have been teaching about variation and staple food crops in the teaching unit they tested with 8- to 10-year-old children. They started by showing some products made from crop plants and asking the class to carry out a simple comparison of similarities and…

Children may not be aware of the origin of much of their food, especially if they eat mostly processed foods. Schools that operate a garden are able to teach children how common foods are parts of plants. This column discusses resources and science topics related to students in grades preK to 2. In this month's issue students focus on…

Building on the home cultural practices related to science can facilitate scientific literacy development of preschoolers. Using a sociocognitive and sociocultural approach and "funds of knowledge" as a theoretical framework, this article describes how Mexican American parents and young children identified the science concepts and knowledge…

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)

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)

This guide is a work in progress; to be continually updated with further information (more stimulating experiments and unusual facts), consequently not every page will have a corresponding page in the activity book. It was created to provide teachers with a useful, informative resource regardless of their educational emphasis. It aims at helping…

Presents material for a talk and demonstration about the relationship of potato types to their different uses by consumers and processors. Includes background information for the instructor and discussions to accompany classroom exercises. Discusses the history of the potato, potato types and external characteristics, and internal characteristics…

Gardening helps children learn how plants sprout, grow, bloom, and then wither away, leaving seeds behind. Participating in this natural process allows children to experience the stages of life. Suggested gardening activities include studying dandelions, focusing on culture for garden plant selection, and constructing a worm box or worm terrarium…

This guide contains hands-on science activities to connect middle-school students to the traditional knowledge of their grandparents and elders. Because girls often lose interest in science at the middle-school level, and because women in some communities (especially in rural areas) are seldom involved in work with an obvious science basis, the…

Through the 4-H Wheat Science project, students learn the importance of wheat from the complete process of growing wheat to the final product of bread. The curriculum is designed to include hands-on experiences in science, consumer education, nutrition, production economics, vocabulary, and applied mathematics. Teachers can select those units out…
