In his book, "A Whole New Mind", Daniel Pink champions the benefits of right-brained thinking: creativity, flexibility, empathy, and meaning. He stresses the need to not only be logical, but also aware of emotion; to not only be sequential, but also conceptual; and to not only be calculating, but also recognize value. The project described in this…

Educational robotics activities are gaining in popularity. Though some research data suggest that educational robotics can be an effective approach in teaching mathematics, science, and engineering, research is needed to generate the best practices and strategies for designing these learning environments. Existing robotics activities typically do…

Images, diagrams, and other forms of visualization are playing increasingly important roles in molecular life science teaching and research, both for conveying information and as conceptual tools, transforming the way we think about the events and processes the subject covers. This study examines how upper secondary and tertiary students interpret…

World Diabetes Day (November 14) offers a wonderful opportunity to educate elementary children about the power they have to control their health. First lady Michelle Obama has urged Americans to educate themselves about childhood obesity, which is often associated with the onset of type II diabetes (Rabin 2010). The authors developed activities to…

We introduced writing activities into a project style third year undergraduate biomolecular science laboratory to assist the students to produce a final report in the form of a journal article. To encourage writing while the experimental work was proceeding, the embedded writing activities required ongoing analysis of experimental data. After…

The past several decades have been times of widespread change in world economies. The 21st century has witnessed scientific technological innovations that have had an impact on almost every sector of our social institutions and the way we do things. To succeed in these changing economies and secure meaningful employment, STEM literacy and…

A leaf is a fundamental unit in botany and understanding what constitutes a leaf is fundamental to many plant science activities. My observations and subsequent testing indicated that many students could not confidently and consistently recognise a leaf from a leaflet, or recognise basic leaf arrangements and the various types of compound or…

The electrical design of the common hair dryer is based almost entirely on relatively simple principles learned in introductory physics classes. Just as biology students dissect a frog to see the principles of anatomy in action, physics students can "dissect" a hair dryer to see how principles of electricity are used in a real system. They can…

Fruit batteries and saltwater batteries are excellent ways to explore simple circuits in the classroom. These are examples of air batteries in which metal reacts with oxygen in the air in order to generate free electrons, which flow through an external circuit and do work. Students are typically told that the salt or fruit water acts as an…

In principle, designing a thermometer scale is easy. The trick lies in persuading others to use your scale. The Homigrade scale is an example of a clever and useful scale that has never caught on. Students can use it as an example of how they might set up their own arbitrary temperature scales.

Many teachers regularly use their own money during the year to pay for miscellaneous teaching materials or to help individual students in need. In this article, the author explains how to secure funds and resources for anything science teachers want to do educationally for their classroom. It's no fantasy; it's simply a matter of thinking ahead…

What do the ideas of Daniel Bernoulli--an 18th-century Swiss mathematician, physicist, natural scientist, and professor--and your students' next landing of the space shuttle via computer simulation have in common? Because of his contribution, referred in physical science as Bernoulli's principle, modern flight is possible. The mini learning-cycle…

We study a system of two RLC oscillators coupled through a variable mutual inductance. The system is interesting because it exhibits some peculiar features of coupled oscillators: (i) there are two natural frequencies; (ii) in general, the resonant frequencies do not coincide with the natural frequencies; (iii) the resonant frequencies of both…

The 5E teaching model provides a five step method for teaching science. While the sequence of the model is strictly linear, it does provide opportunities for the teacher to "revisit" prior learning before moving on. The 5E method is described as it relates to the teaching of aerobic cell respiration.

Science starts at home. Parents play a crucial role in determining how much science their children learn. This paper presents a list of tips that parents can use to help their children learn science. They are: (1) Focus on your child's interests; (2) Talk with your child about what you are doing-- make it a two-way conversation; (3) Girls are just…
