Sessions of our laboratory-based physics course have been "meeting" synchronously online instead of on campus due to the pandemic. Shifting to remote instruction prompted us to create online versions of the course. In the unit on global climate change, for example, we continued engaging students in documenting their initial and evolving…

Powerful online visualizations can make unobservable scientific phenomena visible and improve student understanding. Instead, they often confuse or mislead students. To clarify the impact of molecular visualizations for middle school students we explored three design variations implemented in a Web-based Inquiry Science Environment (WISE) unit on…

This unit of study for secondary students focuses on energy uses, energy sources, energy forms, and energy conversion. The unit is designed to take five 45-minute class sessions. In the first class session, the teacher conducts several energy conversion experiments. In subsequent sessions, students are divided into seven groups and each is…

This unit of study for elementary students focuses on energy uses, energy sources, energy forms, and energy conversion. The unit is designed to take five 45-minute class sessions. In the first class session, the teacher conducts several energy conversion experiments. In subsequent sessions, students are divided into seven groups and each is…

Performance objectives are stated for this secondary school instructional unit concerned with aspects of physical chemistry, involving the physical properties of matter, and laws and theories regarding chemical interaction. Lists of films and state-adopted and other texts are presented. Included are enrollment guidelines; an outline summarizing…

A science and social studies unit developed around rosin is described. Students develop an understanding of the processing of raw material from a plant source into a commercial product and how to protect wood from weathering by preparing, testing, and evaluating varnish and shellac for their wood protective qualities. (Author/DS)

Described is a praparium, a completely sealed and self-contained living aquarium. Steps on how to set up the aquarium, cautions, and a list of suggested aquarium plants and fish are included. (DS)

Presents an alternative series of investigations replacing the propanone-trichloromethane system (Topic 10) in the Nuffield A-Level course. A trichloromethane-ethyl ethanoate (acetate) system presented in four experiments give good results and removed the dangers arising from the other system. Topic 10 need not be re-written, just the replacement…

This handbook contains information that has been used in the high school laboratory by many teachers. Most of the experiments can be adapted for use as individual laboratory exercises or as teacher-student demonstrations. The resource material in this handbook should be helpful to all physics teachers as they continue to adapt their courses to…

This unit is one of 10 first year units produced by the Independent Learning Project for Advanced Chemistry (ILPAC). The unit, which consists of two levels, focuses on the elements and compounds of Group IV (halogens) of the periodic table. Level one deals with the physical and chemical properties of the individual elements. Level two considers…

Highlights assessment issues which the Department of Biological Sciences at the Manchester Metropolitan University has addressed in developing an integrated approach to course provision, in particular for implementing first-year laboratory practical units. Beneficial outcomes and some continuing problems are also considered. (LZ)

This unit on the principles of equilibrium is one of 10 first year units produced by the Independent Learning Project for Advanced Chemistry (ILPAC). The unit consists of two levels. After a treatment of non-mathematical aspects in level one (the idea of a reversible reaction, characteristics of an equilibrium state, the Le Chatelier's principle),…

The Zimbabwe Secondary School Science Project (ZIM-SCI) developed student study guides, corresponding teaching guides, and science kits for a low-cost science course which could be taught during the first 2 years of secondary school without the aid of qualified teachers and conventional laboratories. This ZIM-SCI study guide presents activities…
