Kranz, Johanna; Baur, Armin; Möller, Andrea – Studies in Science Education, 2023
In today's world shaped by technology and the natural sciences, knowledge and skills related to experimentation are crucial, especially given growing public debates about science-related topics. Despite a strong emphasis on experimentation in science curricula worldwide, learners still encounter diverse challenges when experimenting. This paper…

Pendrill, Ann-Marie – Physics Education, 2021
Take a selection of balls and marbles along to a nearby playground slide and let students investigate factors that may influence how balls accelerate down an inclined plane. Students can make hypotheses in small groups, plan investigations to test multiple possible explanations and draw conclusions about the importance of different variables. The…

Kuntzleman, Thomas S. – Journal of Chemical Education, 2015
An activity is described wherein students observe dynamic floating and sinking behavior of plastic pieces in various liquids. The liquids and solids are all contained within a plastic bottle; the entire assembly is called a "density bottle". After completing a series of experiments that guides students to think about the relative…

Segedinac, Mirjana D.; Rodic, Dušica D.; Roncevic, Tamara N.; Horvat, Saša; Adamov, Jasna – Center for Educational Policy Studies Journal, 2020
The first PhD thesis in the field of Chemistry Education at the Faculty of Sciences, University of Novi Sad, was defended in 1992. This can be regarded as the symbolic dawn of Chemistry Education as a scientific discipline in this region. After the official breakup of the Socialist Federal Republic of Yugoslavia, research that had started in the…

Paul, Jürgen; Lederman, Norman G.; Groß, Jorge – International Journal of Science Education, 2016
Experiments are essential for both doing science and learning science. The aim of the German youth science fair, "Jugend forscht," is to encourage scientific thinking and inquiry methods such as experimentation. Based on 57 interviews with participants of the competition, this study summarises students' conceptions and steps of learning…

Selco, Jodye I.; Bruno, Mary; Chan, Sue – Journal of Chemical Education, 2012
A hands-on, minds-on inquiry chemistry experiment was developed for use in K-12 schools that enables students to combine the chemicals of their choice and observe the results. The chemistry involved is water based and builds upon acid-base, double displacement, and iodometric detection of starch reactions. Chemicals readily available in the…

Cloonan, Carrie A.; Andrew, Julie A.; Nichol, Carolyn A.; Hutchinson, John S. – Journal of Chemical Education, 2011
This article describes an activity that can be used as an inquiry-based laboratory or demonstration for either high school or undergraduate chemistry students to provide a basis for understanding both vapor pressure and the concept of dynamic phase equilibrium. The activity includes a simple setup to create a closed system of only water liquid and…
