Plant extracts and their components have been reported to have antimicrobial properties against phytopathogens. Although such properties could be harnessed for the development of new pathogen control strategies, there are no standardised methods for their assessment in different extracts. The laboratory exercise presented here involves the use of…

Environmental education (EE) is a concern in modern society. Plant blindness and nature-deficit disorder highlight how important nature contact and plant consciousness is for urban populations. Considering rapid urbanisation, these phenomena are of increasing concern in China. Integrating EE curricula in Chinese cities is necessary to help younger…

Purpose: The purpose of this article is to untangle the influence of Linda Tuhiwai Smith's "Decolonizing Methodologies" on botanical gardens, particularly in the context of commemorating 25 years since its publication. By examining the intersections between decolonial theory and botanical practices, this article seeks to elucidate the…

Especially within the light of the current loss of biodiversity, we want our students to gain a better understanding of the issues at stake in order to take action and support plants and their pollinators. Many educational approaches focus on honeybees, disregarding the vast diversity in the context of pollination systems and the complex…

Recent biological research (Trewavas, 2003; Mancuso & Viola, 2013; Gagliano, 2018) has (re)demonstrated the variety and complexity of the adaptive behaviour of plants. In parallel with these findings, and in acknowledgement of the important role played by plants in the biosphere and climate of the planet, the representation of plants in…

The yellow-blue color pair has been used in creative artwork such as paintings and designs and in color engineering. Herein we present a method for using the yellow-blue combination in a chemistry lesson dealing with [pi]-conjugated molecules for first-year undergraduate students who are not science majors. The lesson begins with an introduction…

An undergraduate laboratory experiment has been developed for the synthesis of a reactive cross-linker that is useful in various highly visual demonstrations of organic reactivity, click chemistry, and biobased polymer synthesis. A triazolinedione-based cross-linker, which is known as a useful reagent for click chemistry, can be obtained from…

The growing interest in outdoor early childhood education, even in countries with a weak environmental tradition such as Portugal, tends to be associated with a concern over the alienation between urban/Western children and nature. While educational projects in nature criticize this separation, they still maintain a bad culture vs good nature…

Raman scattering spectroscopies are important analytical tools in modern chemistry. Here, we describe the construction of the unamplified Raman scattering analysis (URSA) instrument: an inexpensive, open-table Raman spectrometer that uses a 532 nm diode-pumped laser as a light source. Upon application of this spectrometer to DNA extracted from…

In the past few decades, chemistry has evolved to interact with various disciplines to synergistically help tackle global challenges. This, in turn, requires that newer generations of chemistry students are trained to be more flexible in accepting and coordinating new concepts. In this experiment, pineapple was used as a key model to allow for the…

How might fourth graders address the problem of measuring the size of a leaf? And why might their classroom teachers choose such a shape to measure? One group of fourth-grade students in an urban Australian school were interested in knowing the sizes of leaves on a passionfruit vine growing at their school. The children were excited after a visit…

When most people think "King Island," they think of a place synonymous with premium Australian dairy products. But hidden away from the lush, green pastures of grazing cows is an island teeming with invertebrate and plant species. You could probably eat some of those too, but that wasn't the intent of the Bush Blitzers who set off to…

Poinsettia ("Euphorbia pulcherrima") contains anthocyanins that dissolve in water and exhibit color changes due to changing pH. This property makes the poinsettia extract a useful acid-base indicator for pH demonstrations. When combined with common household materials, this experiment can be used as an alternative low-cost tool in…

The CRISPR/Cas9 system is widely used for editing genes in various organisms and is a very useful tool due to its versatility, simplicity, and efficiency. To teach its principles to post-graduate students we designed a laboratory activity to obtain and analyze PDS3 mutants in "Arabidopsis thaliana" plants consisting of: 1) Design of…

The use of red cabbage ("Brassica oleracea var. capitata F. rubra") extract as a pH indicator is a versatile and popular demonstration that is employed by educators in many schools and universities. Previous variations of this demonstration have used red cabbage extracts to prepare paper that changes color when solutions of acid or base…
