As well-developed as they may be, standards are not curriculum. It is the job of teachers and curriculum teams to use the Standards as the basis for designing the specific pathway for teaching and learning. In this article, the authors explore the use of Understanding by Design (UbD), a widely-used curriculum development framework, for honoring…

Allelopathy plays crucial roles in invasive plant viability and agricultural production systems. However, there is no well-established hands-on learning activity to teach the concept of allelopathy. Nor is there an activity which allows students to gain knowledge about glucosinolates and their corresponding enzyme, myrosinase, which are present in…

The Garden Team at Washington State University is a transdisciplinary group of faculty, staff, and students with expertise in applied plant and soil sciences and an interest in Extension education. The team's primary mission is to create current, relevant, and peer-reviewed materials as Extension publications for home gardeners. The average yearly…

Early detection, rapid response is a critical component of invasive plant management. It can be challenging, however, to detect new invaders before they become established if landowners cannot identify species of concern. In order to increase awareness, eye-catching postcards were developed in Washington State as part of a noxious weed educational…

Evidence is mounting that children have decreasing exposure to the natural world, which makes sense as the population of the planet urbanizes and many interests and assignments involve digital technology. According to the United Nations, 54% of the world's population now live in cities (2014), and a 2010 study by the Kaiser Health Foundation found…

The authors describe how grade 4 students carried out an investigation about growing cucumbers (members of the curcurbit or gourd family) where they read information sources about seed variety; germinated seeds under different conditions; measured and partitioned growing spaces; collected and analyzed data on germination, true leaf growth, and…

This article describes how a farm-based class in the Great Lakes region investigated how plants and animals prepare for winter. Two groups of children, ranging in ages from three to five years old, had a farm, pasture, gardens, forest, and a pond available for exploration. A low teacher-to-child ratio was maintained, with one teacher to…

We report here the development of an inexpensive and engaging laboratory-based activity that can help students learn about the scientific method and the role of plant epicuticular waxes and surfactant function on waxy plant leaves as real life example in the agricultural industry. Three each of nontreated collard leaves ("Brassica…

In 2018 the Gulf coast of Florida suffered extensive damage from harmful algal blooms (HABs), from as far north as Clearwater Beach south to Naples. The bloom lasted nearly a year, picking up in intensity during the late summer months. HABs occur when conditions such as reduced salinity, higher water temperatures, light saturation, and currents…

In this classroom activity, students build a phylogeny for woody plant species based on the morphology of their twigs. Using any available twigs, students can practice the process of cladistics to test evolutionary hypotheses for real organisms. They identify homologous characters, determine polarity through outgroup comparison, and construct a…

Native plants are not typically the kinds of plants that are used in elementary classroom studies of plant biology. More commonly, students sprout beans or investigate with fast plants. At the time the authors started their plant unit (November), the school-yard garden had an abundance of native plants that had just started seeding, including…

Indigenous Australians are significantly underrepresented in chemistry based professions, which arises from their low participation in physical science subjects in secondary and tertiary education. This is a multifaceted issue with a number of identified solutions, one of which is to link chemistry with aspects of Indigenous culture. Here, four…

The Arnold Arboretum Field Study Program provides outdoor experiences for children in order to develop authentic firsthand knowledge of life sciences. The Arboretum welcomes approximately 3,200 children (preK-5) from greater Boston annually. During the program called Explorations with Head Start participants, the children visit three times…

In this paper I share my understandings of an elective outdoor environmental education course, a significant component of which was a field school. I helped develop this course at the Canadian university where I work as an academic, with the field school conducted on the island of Kaua'i in Hawaii. The paper describes the university field school…

This column focuses on promoting learning through assessment. Formative assessment probes are designed to uncover students' ideas about objects, events, and processes in the natural world. This assessment information is then used throughout instruction to move students toward an understanding of the scientific ideas behind the probes. During the…
