Botanical gardens (BGs) are important agencies that enhance human knowledge and attitude towards flora conservation. By following free-choice learning model, we developed a "Discovery map" and distributed the map to visitors at the Xishuangbanna Tropical Botanical Garden in Yunnan, China. Visitors, who did and did not receive discovery…

Plants are often overlooked in favour of animals when teaching about living things. Focusing on familiar animals that share human characteristics helps young children learn about similar features. Examining plants for their differences, though, helps foster wonder. In the author's experience, children find it intriguing that plants need…

This study examined whether children 4- and 5-years-old (N = 156) can revise a physical science misconception from different types of picture books. A realistic fiction book and informational book with identical images matched in word count and reading difficulty level were compared to a control book about plants. In the pretest and posttest,…

This grounded theory study explored the pedagogical content knowledge (PCK) of experienced agriculture teachers in the plant sciences. The central phenomenon that emerged during data collection and analysis was the influence of beliefs on shaping participants' PCK. This finding guided subsequent collection and analysis that resulted in the…

Civilization simply would not exist without plants, yet their importance is often overlooked. As the nation's ability to respond to the botanical challenges associated with food production, climate change, invasive species, and biodiversity loss continues to decrease (Kramer, Zorn- Arnold, and Havens 2010), educators must discourage this…

The basis of cultivated lands consists of the interacting populations of annual and perennial weeds and updated annually cultural annual plants, which have very limited data on the aboveground net production, and even less information about the yield of their underground organs. The aim of the research is scientific and theoretical development of…

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…

A two-week experiment is presented in which students can observe the impact of nanoparticles on the concentration of chlorophyll in plants. First-year students in an introductory nanotechnology laboratory course and a general chemistry laboratory course synthesized silver nanoparticles and then exposed stalks of "Egeria densa" ("E.…

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 article, we describe our students-as-partners process for bringing undergraduate and academic staff together to develop a mobile application (app) -- CampusFlora -- for use across our campuses. Our project at the University of Sydney, Australia, was conceived as a way to improve the botanical literacy of biology students by engaging…
