Brown, Patrick – Science and Children, 2023
Science and engineering practices (SEPs) and crosscutting concepts (CCs) constitute a significant part of "A Framework for K-12 Science Education" (NRC 2012). As teachers, the role of the authors is to highlight the pivotal role that both scientific knowledge and the practices used to generate knowledge play in learning. This article…

Xiong, Qing; Luo, Mingliang; Bao, Xiaoming; Deng, Yurong; Qin, Song; Pu, Xuemei – Journal of Chemical Education, 2018
This experiment is dedicated to second-year and above undergraduates who are in their experimental session of the analytical chemistry course. Grouped students are required to use a TiO[subscript 2] photocatalytic oxidation process to treat the methanol-containing wastewater that resulted from their previous HPLC experiments. Students learn to…

Dunnett, K.; Bartlett, P. A. – Physics Education, 2018
It was planned to introduce online pre-laboratory session activities to a first-year undergraduate physics laboratory course to encourage a minimum level of student preparation for experiments outside the laboratory environment. A group of 16 and 17 year old laboratory work-experience students were tasked to define and design a pre-laboratory…

McGee, Christy – Gifted Child Today, 2018
Tomlinson's explanation of Artful Teaching and her 2017 expansion of this concept The Five Key Elements of Differentiation provide the theoretical framework of this examination of the need for science investigations in elementary schools. The Artful Teaching framework uses an equilateral triangle with vertices labeled The Teacher, The Student, and…

Drummond, Gordon B.; Vowler, Sarah L. – Advances in Physiology Education, 2012
In this article, the authors talk about variation and how variation between measurements may be reduced if sampling is not random. They also talk about replication and its variants. A replicate is a repeated measurement from the same experimental unit. An experimental unit is the smallest part of an experiment or a study that can be subject to a…

Drummond, Gordon B.; Vowler, Sarah L. – Advances in Physiology Education, 2012
In this article, the authors consider the possibility that groups could be different, because of the different conditions of a factor. This is as far as the analysis can extend: the consideration is restricted to groups characterized by the different category of the factor being considered. In many biological experiments, the factor considered may…

King, David; Friend, Jeffrey; Kariuki, James – Journal of Chemical Education, 2010
A pencil lead successfully served as an electrode for the determination of ascorbic acid in commercial orange juice. Cyclic voltammetry was used as an electrochemical probe to measure the current produced from the oxidation of ascorbic acid with a variety of electrodes. The data demonstrate that the less expensive pencil lead electrode gives…

Lee, Jung Sook; Chae, Min; Kim, Jung Bog – Physics Teacher, 2010
A recent article by Morse described interesting electrostatics experiments using an MBL charge sensor. In this application, the charge sensor has a large capacitance compared to the charged test object, so nearly all charges can be transferred to the sensor capacitor from the capacitor to be measured. However, the typical capacitance of commercial…

Velasco, S.; White, J. A.; Roman, F. L. – Physics Teacher, 2010
The effect of density inversion on the convective flow of water in a spherical glass flask cooled with the help of an ice-water bath is shown. The experiment was carried out by temperature measurements (cooling curves) taken at three different heights along the vertical diameter of the flask. Flows inside the flask are visualized by seeding the…

Brewer, Sharon E.; Cinel, Bruno; Harrison, Michelle; Mohr, Christina L. – International Review of Research in Open and Distance Learning, 2013
In delivering chemistry courses by distance, a key challenge is to offer the learner an authentic and meaningful laboratory experience that still provides the rigour required to continue on in science. To satisfy this need, two distance general chemistry laboratory courses appropriate for Bachelor of Science (B.Sc.) students, including chemistry…

Miles, Deon T.; Bachman, Jennifer K. – Journal of Chemical Education, 2009
Recent emphasis on the science of food and cooking has been observed in our popular literature and media. As a result of this, a new non-science majors course, The Science of Food and Cooking, is being taught at our institution. We cover basic scientific concepts, which would normally be discussed in a typical introductory chemistry course, in the…

Goncalves, Fernando J., Ed.; Pereira, Ruth, Ed.; Leal Filho, Walter, Ed.; Miranda Azeiteiro, Ulisses, Ed. – Peter Lang Frankfurt, 2012
This book presents essential learning approaches. It introduces educational and training activities, as well as various innovative methods aiming at the development of practical skills, in order to strengthen the continuous process of environmental education, and in particular the education for sustainable development (ESD). In doing so, it…

Pelter, Michael W.; Pelter, Libbie S. W.; Colovic, Dusanka; Strug, Regina – Journal of Chemical Education, 2004
The sequence of microscale mixing of 1-bromo-3-chloro-5-iodobenzene along with reductive deamination of 4-bromo-2-chloro-6-iodoaniline is described. This novel deamination approach is beneficial in final product separation and higher product output.
