A green chemistry experiment is presented for teaching an undergraduate quantitative analysis/analytical chemistry laboratory class through the use of black tea leaf extract for the determination of iron in supplement tablets. Dried tea leaf is a safe, low cost, and widely available source of natural extract that can be used in place of more toxic…

To investigate how early elementary science and technology (S&T) education, with hands-on experimentation and inquiry-based learning, impacts pre-service teachers' attitudes and confidence to teach S&T education, we used a cross-sectional survey. Our participants were 27 pre-service teachers enrolled in an Ontario elementary S&T…

Aim/Purpose: The objective of this study is to explore the effectiveness of using virtual experiments on students' level of achievement and on their practical skills as well as their views on applying the virtual experiments in a general physics lab. Background: There is a continuous debate in the literature on the effect of using virtual…

In this paper we display an example of how educational software Geogebra can be used as a tool for the STEM education. Geogebra is used in the process of introducing students in high school to mathematical models of materials science. Scientific results from materials science experiments were used for mathematical modelling and learning about the…

Melton demonstrated a surprising disappearance using total internal reflection. When he put a Florence flask filled with marbles into a water tank and looked straight down from directly above the flask, he was only able to see marbles above a certain water level. When he added more water into the tank above the top line of the marbles, all of the…

This research reports the assessment of pre-service teachers' reception and attitudes towards virtual laboratory experiments in Life Sciences with the aim of advancing adaptability to digital learning. Using sequential mixed-methods in a quasi-experimental design, 68 pre-service teachers in the 3rd year of a Bachelor of Education (B.Ed) program…

Three days into the academic year, the COVID-19 pandemic abruptly led to emergency remote teaching, ERT, of Chemical Experimentation--a revised alternative to the majors' General Chemistry Laboratory at the University of Costa Rica. The course was reoriented to support students' development of nontechnical experimentation skills and scientific…

The author believes that science within a primary school is there to enable children to be interested in the world around them and to help them start to understand it, getting them interested in the very basics, and pointing out things around them that they had not considered, so that they can start asking the questions 'why' and 'how' and 'what'…

The Australian Science Teachers Association offers an innovative international professional development program for science teachers called the Science Teachers Exchange -- Japan. The program offers Australian and Japanese teachers an opportunity to travel to the corresponding country, allowing the teachers to grow in their knowledge of the…

The goals of this advanced physics laboratory course emphasized not only to improve students' physics knowledge but also spectrum scientific abilities in particular for preparing their future-ready competencies. One of those scientific abilities was initiated to study that was "the ability to design experiment". It was the fundamental…

Undergraduate-level laboratory experiments that involve the synthesis of nanomaterials with well-defined/controlled shapes are very attractive under the umbrella of nanotechnology education. Herein we describe a low-cost and facile experiment for the synthesis of Cu(OH)[subscript 2] and CuO nanowires comprising three main parts: (i) synthesis of…

Scientific inquiry requires the replication of results in experimental studies. Recent studies draw a severe picture on the need of replication and the difficulties in replicating already published studies. As replicated confirmation of results is the basis of scientific and medical research, there may be a need to introduce the topic of…

Natural products are ubiquitous in nature but do not form a large proportion of the A-level syllabuses in the UK. In this article we briefly discuss a small selection of natural products, focusing on alcohols, aldehydes and ketones, and alkaloids. We then outline two natural product experiments that are suitable for A-level chemistry clubs or…

Lab-based learning is an essential part of any undergraduate chemistry curriculum as it incorporates necessary and required hands-on experiential learning. However, in response to the COVID-19 pandemic, many students are learning from home, rendering laboratory instruction a particular challenge. Options for educators include third party virtual…

Without any major changes, a pilot version of a physical science lab course was able to continue when the COVID-19 crisis necessitated the abrupt suspension of on-campus education. The 'Maker Lab' course, in which students conceive and set up their own experiments using affordable microcontrollers, required students to follow the entire arc of the…
