Youssef, Mena; McKinstry, Emery L.; Dunne, Aisling; Bitton, Ariana; Brady, Anna G.; Jordan, Trace – Journal of Chemical Education, 2020
The global COVID-19 pandemic required science educators to rapidly redesign their courses to instruct, support, and motivate students in a new remote learning environment. This adjustment was particularly challenging for courses with a laboratory component, where beakers and pipettes were exchanged for computer screens and keyboards. We present…

Riveros, Héctor G. – European Journal of Physics Education, 2019
This paper discusses the importance of one of the most crucial elements in science and technology education: the development of the individual capacity to cope with new problems. Also, discuss the importance of being aware of the existence of "formative objectives" and "tacit knowledge". In the planning of a course, taking into…

Hike, Nina; Beck-Winchatz, Bernhard – Science Teacher, 2015
Many students probably know something about space from playing computer games or watching movies and TV shows. Teachers can expose them to the real thing by launching their experiments into near space on a weather balloon. This article describes how to use high-altitude ballooning (HAB) as a culminating project to a chemistry unit on experimental…

Morgan, Erin E.; Hiebert, Laurel S. – Science and Children, 2010
The "Testable Question Relay" was created as part of a fourth-grade unit on conducting science experiments. In the relay, student teams raced to "outfit a scientist" by correctly categorizing questions as testable or untestable and earning scientific tools. This activity assists upper-elementary students in recognizing the components of good…

Huck, Lawrence A.; Leigh, William J. – Journal of Chemical Education, 2010
A modification of the mixed-aldol synthesis of dibenzylideneacetone, prepared from acetone and benzaldehyde, is described wherein acetone is replaced with a series of cyclic ketones with ring sizes of 5-7 carbons. The structural variations in the resulting conjugated ketones produce regular variations in the UV-vis absorption spectra. The choice…

Serafini, Amanda; Matthews, Dorothy M. – American Biology Teacher, 2009
Natural selection is the mechanism of evolution caused by the environmental selection of organisms most fit to reproduce, sometimes explained as "survival of the fittest." An example of evolution by natural selection is the development of bacteria that are resistant to antimicrobial agents as a result of exposure to these agents. Triclosan, which…

Sampson, Victor; Grooms, Jonathon; Walker, Joi – Science Teacher, 2009
Argument-Driven Inquiry (ADI) is an instructional model that enables science teachers to transform a traditional laboratory activity into a short integrated instructional unit. To illustrate how the ADI instructional model works, this article describes an ADI lesson developed for a 10th-grade chemistry class. This example lesson was designed to…

McEwan, Birgitta – Journal of Biological Education, 2008
The following experiment describes an easy experiment for children 11-12 years old, performed during spring in a compulsory school near Karlstad, Sweden. Four different ripe fruits were placed under flowering plants of Impatiens New Guinea (Impatiens hawkeri) for four days on a table and with plastic bags around both plants and fruits. For one of…

Su, Jun-Ming; Lin, Huan-Yu; Tseng, Shian-Shyong; Lu, Chia-Jung – Turkish Online Journal of Educational Technology - TOJET, 2011
Promoting the development of students' scientific inquiry capabilities is a major learning objective in science education. As a result, teachers require effective assessment approaches to evaluate students' scientific inquiry-related performance. Teachers must also be able to offer appropriate supplementary instructions, as needed, to students.…
