Xiang, Lin; Srinivasan, Madhusudan – Journal of College Science Teaching, 2023
Integrating authentic research practices into introductory laboratory courses to prepare tomorrow's scientists has become increasingly prevalent over the past decade. However, an incomplete understanding of the nature of science (NOS) and authentic scientific inquiry (SI) precludes higher-level learning in undergraduate research experiences. In…

Rizik, Nadya; Taylor, Subhashni; Taylor, Neil; Sharma, Manjula – Teaching Science, 2018
Energy is one of the most complex yet central concepts taught in schools and is featured in the Australian Science Curriculum, as one of the six key organising ideas (Australian Curriculum, Assessment and Reporting Authority (ACARA), 2015). The literature portrays a multitude of complications associated with teaching energy (see Millar, 2005 for a…

Johnson, Christopher D.; Montgomery, Laura E. A.; Quinn, Joe G.; Roe, Sean M.; Stewart, Michael T.; Tansey, Etain A. – Advances in Physiology Education, 2016
This laboratory session provides hands-on experience for students to visualize the beating human heart with ultrasound imaging. Simple views are obtained from which students can directly measure important cardiac dimensions in systole and diastole. This allows students to derive, from first principles, important measures of cardiac function, such…

Bierema, Andrea M.-K.; Rudge, David W. – American Biology Teacher, 2014
One of the key aspects of natural selection is competition, yet the concept of competition is not necessarily emphasized in explanations of natural selection. Because of this, we developed an activity for our class that focuses on competition and provides an example of the effects of competition on natural selection. This hands-on activity models…

Bindel, Thomas H. – Journal of Chemical Education, 2012
A hands-on laboratory exercise at the general chemistry level introduces students to chemical equilibrium through a simulation that uses poker chips and rate equations. More specifically, the exercise allows students to explore reaction tables, dynamic chemical equilibrium, equilibrium constant expressions, and the equilibrium constant based on…

Redfern, James; Burdass, Dariel; Verran, Joanna – Journal of Biological Education, 2013
School science laboratory classes and hands-on public engagement activities share many common aims and objectives in terms of science learning and literacy. This article describes the development and evaluation of a microbiology public engagement activity, "The Good, the Bad and the Algae", from a school laboratory activity. The school…

Sultana, Khalida; van Rooy, Wilhelmina – Teaching Science, 2009
Extracting DNA from fruit and vegetables provides students with hands-on opportunities to engage with a visualisation of genetic material that can later be supported by ICT and practical model making. Here is a quick, cheap and easy way to extract DNA from strawberries that avoids the mess involved in other DNA extractions, such as from dried…

Hassoun, Lama; Hable, Whitney; Payne-Ferreira, Tracie L. – American Biology Teacher, 2008
Hands-on biological exploration has been shown to have a great impact on learning. When students "do" something, they remember more details than when they sit through a lecture describing the same activity. In this article, the authors present an exercise that has the potential to get all levels of students into the lab for practical experience…

Franklin, Bill – AAPT Press (BK), 2004
This American Association of Physics Teachers/Physics Teaching Resource Agents (APPT/PTRA) spiral-bound manual features labs and demos physics teachers can use to give students hands-on opportunities to learn about impulse and momentum. "Make-and-take activities" include AAPT Apparatus Contest winners "An Air Impulse Rocket," "A Fan Driven…

Ward, R. Bruce; Sadler, Philip M.; Shapiro, Irwin I. – Astronomy Education Review, 2008
We report on an evaluation of the effectiveness of Project ARIES, an astronomy-based physical science curriculum for upper elementary and middle school children. ARIES students use innovative, simple, and affordable apparatus to carry out a wide range of indoor and outdoor hands-on, discovery-based activities. Student journals and comprehensive…
