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…

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…

Severe flooding was prevalent within the authors' region at the beginning of the school year. Many homes and fields were affected by the amount of rain that fell within a short period of time over multiple days. Their students were concerned about the impact this natural phenomena was having on their local community. Natural phenomena can provide…

The diet of many students consists of on-the-go processed food. As part of a larger school garden project, the authors wanted students to consider the relevance of plants in their own lives, both as food sources for us and for the animals that we eat. In this article, they present a mini-unit they taught in a third-grade classroom that helped…

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…

This article describes an interrupted case study that intersperses information about diffusion and osmosis with content review and knowledge application questions, as well as a simple experiment that can be conducted without the use of a laboratory. The case study was developed for use in an introductory undergraduate biology course. The case…

This paper attempts to answer this question: what should ecoliteracy mean in a biocapitalist society? The author situates his analysis of this question within the general context of the neoliberal reconstruction of education in the US. Specifically, focus is given to the shared model of governmentality GE food industries and education policies…

Nationally, both science and agricultural education professional organizations have identified agriculture as a fundamental technology to be studied by students, with the goal of achieving an understanding of the agri-food system necessary for democratic participation. Benchmarks representing the content that K-12 children need to understand about…

"Community," "assemblage," "network," "complex," "interdependent," "web," and "synergism"--definitions of an ecosystem often include these words to highlight the dynamic interrelated workings of plants and animals with their physical environment. Young children don't understand the complexities of ecosystems, but they can begin to understand that…

Most history books for children focus on people, places, and events. In a different approach, some authors focus on an object--an everyday item that might be ignored when it comes to writing history. They shine a spotlight on the item, and in the process, they add insight and interest to human history. This article looks at four outstanding books…

This textbook is an elementary natural science book. It was translated from French. Changes and additions were necessary to Americanize the book, and adapt it to the requirements of public and private schools as well as to home instruction in the United States. The Natural History section has been slightly enlarged by the introduction of several…
