Without any major changes, a pilot version of a physical science lab course was able to continue when the COVID-19 crisis necessitated the abrupt suspension of on-campus education. The 'Maker Lab' course, in which students conceive and set up their own experiments using affordable microcontrollers, required students to follow the entire arc of the…

A simple demonstration that is occasionally used in the classroom to show that light carries momentum involves making an orchestral cymbal audibly ring using light from a common photoflash. A metal plate or a piece of foil can also be used; however, it appears that many people use a cymbal because the sound is easily heard at a reasonable…

Achievement in primary school science courses has always been a field of interest by researchers in Turkey and other countries. For this reason, studies are conducted on science teaching at the primary school level. This study aimed to examine strengths and weaknesses of pre- and in-service primary teachers in science teaching. In addition, to…

Young people now must compete in a global, knowledge-based, innovation-centered economy; they must acquire not just academic knowledge, but also character attributes such as intrinsic motivation, persistence, and flexibility. To accomplish these ambitious goals, the National Research Council (2012) of the United States recommends the use of…

The EU as a context for science lessons may be given scant attention but EU decision-making is a vital factor in everyday life. Lessons on the emergence of soil science with Charles Darwin's simple scientific experiments can be linked with competence through action, inclusion and argumentations in science lessons. Decisions about an EU Soil…

A wind energy focused curriculum for grades 4-8 was designed and implemented to promote the understanding of wind energy concepts with American Indian students. 57 students who participated in the 2009 summer program of the "Reach for the Sky" (RFTS) Science, Technology, Engineering, and Mathematics (STEM) received the curriculum. The…

Biobottles are miniature ecosystems made from 2-liter plastic soda bottles. They allow students to explore how organisms in an ecosystem are connected to each other, examine how biotic and abiotic factors influence plant and animal growth and development, and discover how important biodiversity is to an ecosystem. This activity was inspired by an…

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…

Describes demonstrations suitable for secondary school biology classes relating to the effects of the hormone IAA on plant growth. Demonstrations illustrate how hormone treatments affect stem elongation, callus formation, inhibition of axillary buds, stimulation of secondary growth and initiation of adventitious root development, root elongation,…

Presents a teaching unit on the Langmuir absorption isotherm suitable for advanced secondary school chemistry classes. Describes the experimental investigation of the isothermal adsorption of sulfur dioxide on charcoal, and discusses the derivation of the Langmuir equation and some applications. (JR)

Describes the procedure for making a quantitative analysis of organic compounds suitable for secondary school chemistry classes. Using the Schoniger procedure, the organic compound, such as PVC, is decomposed in a conical flask with oxygen. The products are absorbed in a suitable liquid and analyzed by titration. (JR)

Contends that demonstration lecturing is a valuable science teaching approach. Highlights the benefits of this technique and identifies sources of information for teachers. Provides a listing of popular science lectures suitable for chemistry classes. Describes in detail the "Major of Chemistry" demonstration. (ML)
