Kova´cs, Lajos; Betya´r, Ga´bor; Korom, Erzse´bet – Journal of Chemical Education, 2021
Chemistry curricula in part rely on the use of laboratory demonstrations and experiments. The complex nature of this kind of educational activity has been posing challenges from the very early days of teaching chemistry. As chemistry is an experimental science, one possible approach to make the teaching of this subject more efficient is to use…

Sewry, Joyce D.; Glover, Sarah R.; Harrison, Timothy G.; Shallcross, Dudley E.; Ngcoza, Kenneth M. – Journal of Chemical Education, 2014
Given the emphasis on community engagement in higher education, academic departments need to become more involved in the community. This paper discusses a number of outreach activities undertaken by the chemistry department at Rhodes University, South Africa. The activities range from service learning to community engagement with teachers and…

Cady, Susan G. – Journal of Chemical Education, 2014
The circuit board found in a commercial musical greeting card is used to supply music for electrochemical cell demonstrations. Similar to a voltmeter, the "modified" musical device is connected to a chemical reaction that produces electricity. The commercial 1 V battery inside the greeting card circuit board can be replaced with an…

Nagel, Megan L. – Journal of Chemical Education, 2013
A trip to the mall is used as a classroom demonstration to illustrate the fundamentals of separations without the need for chemicals or any chemistry background. Student volunteers are the "mixture", and depending on the shopping list they have been given, they spend varying amounts of time in the "stores" versus moving through…

Sheppey, Julie – Primary Science, 2016
Thorntree Primary is a small school in Greenwich, London, with strong links to the local community and an appealing village feel that is unusual in its inner London setting. The children come from a mix of cultural and economic backgrounds, with those entitled to free school meals being higher than average. The school has a strong inclusive and…

Roelle, Julian; Renkl, Alexander – Journal of Educational Psychology, 2020
Example-based learning often uses a design in which learners first receive basic instructional explanations of new principles and concepts and then examples thereof. In this sequence, it is crucial that learners self-explain by using the content of the basic instructional explanations to elaborate on the examples. Typically, learners are not…

DeKorver, Brittland K.; Choi, Mark; Towns, Marcy – Journal of Chemical Education, 2017
Chemical demonstration shows are a popular form of informal science education (ISE), employed by schools, museums, and other institutions in order to improve the public's understanding of science. Just as teachers employ formative and summative assessments in the science classroom to evaluate the impacts of their efforts, it is important to assess…

Kuntzleman, Thomas S.; Ford, Nathan; No, Jin-Hwan; Ott, Mark E. – Journal of Chemical Education, 2015
Everyone enjoys seeing the cloudy white fog generated when solid carbon dioxide (dry ice) is placed in water. Have you ever wondered what physical and chemical processes occur to produce this fog? When asked this question, many chemical educators suggest that the fog is produced when atmospheric water vapor condenses on cold carbon dioxide gas…

Kim, Philseok; Alvarenga, Jack; Aizenberg, Joanna; Sleeper, Raymond S. – Journal of Chemical Education, 2013
A visual demonstration of the difference between hydrophilic and hydrophobic surfaces has been developed. It involves placing a shadow mask on an optically clear hydrophobic plastic dish, corona treating the surface with a modified Tesla coil, removing the shadow mask, and visualizing the otherwise invisible message or pattern by applying water,…

Jackson, Julie – Science Activities: Classroom Projects and Curriculum Ideas, 2009
Learning about states of matter is fun and exciting when students, acting as water molecules, role-play moving from a solid to a liquid to a gas. The 5-E lesson plan model provides the framework for this activity, ensuring that students actively engage in inquiry science while creatively constructing knowledge. (Contains 2 figures.)
