Allison B. Wallace describes a seminar in organic horticulture she created and teaches as part of an honors curriculum. She answers the question of how gardening is appropriate for high-ability college students by saying that she believes efforts to raise plants by relatively non violent means teaches and disciplines students in an ethical way to…

Though the significance of involving children in environmental sustainability efforts is widely acknowledged, we still lack evidence on what they think of environmental issues and about the protection of nature. The aim of the paper is to systematically describe the reasons that children give for protecting the environment. Thirty-three children…

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…

By all appearances, Montana's Fort Belknap fits the United States Department of Agriculture's (USDA's) definition of a food desert perfectly. There are no supermarkets on the 1,000-square-mile reservation. Most residents of this Indian reservation, especially those living on the southern end of the reservation, must drive long distances to buy…

"In the twentieth century, we humans began to transform our surroundings, our societies, and even ourselves. Without really intending to, we have introduced changes so rapid and so massive that our species has become the equivalent of a new geological force. That is why many scholars have begun to argue that planet Earth has entered a new…

African violet (genus "Saintpaulia") was identified as a particularly suitable genus for the study of specialised plant cells in the classroom using microscopes. The techniques described here involve simple preparation without staining. The cells and structures that can be investigated include: trichomes (hairs); stomata; guard cells and…

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…

A weed garden was constructed to quantify and improve identification skills among clientele. The garden was planted with over 100 weed species based on surveys on problematic weeds. The weed garden proved useful for introducing additional hands-on learning activities into traditional lecture-based seminars. Through seminar and field day attendee…

The main focus of this study is to determine pre-service science teachers' cognitive structure about trichome and stoma through two alternative assessment techniques: metaphor and word association test. The study was conducted with 35 pre-service science teachers. Word association test given stoma and trichome as stimulant words was applied. Also…

There is always debate about when, where, and how to introduce students to vocabulary when teaching science. The authors argue that there is not necessarily a singular correct order or right time to introduce new vocabulary to students. Rather, what is important is that we support students in learning the language they need to engage in the…

This practical lesson on greenhouses implements standards of the Next Generation Science Standards ("K-2 ETS I-2"; "K-LS1-1") and the preschool objectives from the Teaching Strategies GOLD. Teaching Strategies GOLD is an assessment tool available online and in print that can be used with any developmentally appropriate early…

A series of three practical sessions are designed to give students firsthand experience with the preparation of natural product extracts and assay using a live tissue preparation. Areca or betel nuts are the seeds from the fruit of the "Areca catechu" palm tree that is known to contain a number of pharmacologically active alkaloids. The…

This article reports on how the people of the Tiwi Islands (which lie in the Arafura Sea located off the coast of Darwin in Australia's Northern Territory) have carefully observed the rhythms and patterns of their country, developing a complex and precise way of living sustainably in their island environment. In 2015, the Tiwi people shared their…

Evolution and ecology are essential to an understanding of biology, but questions remain as to when and how young children can learn about these concepts. The concept of adaptation represents an opportunity for children to engage with these ideas, and this article presents several lessons used to teach adaptation to children aged three through six…

Alternative farming techniques are often more efficient and conserve resources more effectively than conventional farming, which can harm the environment with pesticides and synthetic fertilizers (Pimental 2005). To learn the theory, application, and related science concepts of sustainable farming techniques, students can collaborate to create an…
