The climate emergency is a source of anxiety for many young people. Images of drought, heat waves, wildfires, storms and flooding are increasingly appearing in the media. Today's children stand to be the recipients of our legacy of climate change, while not feeling empowered to do anything about it, so perhaps it is no wonder they are anxious.…

When Mentos candies are dropped into a bottle of Diet Coke, a foamy fountain jets out of the beverage container. It has previously been argued that ingredients found in Mentos candies significantly enhance this fountaining effect. Other previous work has demonstrated that the kinetics of foam production can be quantitatively monitored using a…

Sound is an interesting topic for physics lessons at all ages. However, it is difficult to illustrate this ubiquitous phenomenon and many models do not adequately represent the properties of sound and thus promote unwanted conceptions. The experiment presented here avoids this by visualising sound itself with the help of the schlieren technique.…

Life would not be possible without plants. Plants supply food to many organisms (including people), produce oxygen, absorb carbon dioxide from the air, provide products for human use, and homes for many other living things. It is not surprising, therefore, that plant growth is a familiar topic in the primary school science curriculum. This paper…

Science is one of the most important subjects for students at all educational levels. To promote engagement, hands-on experiments can provide a 'realistic and exciting experience of the content' (Holstermann, Grube and Bögeholz, 2010: 744) and hopefully facilitate motivation. In this article, George Stylos and Konstantinos T. Kotsis present four…

Science is the study of the world around us, and a scientist's job is to ask questions about the world and then experiment to find the answers. There is not a more natural scientist than the Elementary child, whose reasoning mind is eager to ask questions, investigate, and discuss and compare findings with their peers. In this article, the authors…

Research has shown that visual literacy is an important element to use within a classroom (Tillmann 2012). One way to incorporate visual literacy into the science classroom is with the use of advertisements. In this article, Tiffany Pace describes how she and her students began their visual literacy quest while studying mixtures and solutions,…

The aims of teaching have evolved along with the society in which we live, from a teaching based in memory to a one that teaches to reason, in order to adapt to the accelerated rate of change imposed by the application of scientific discoveries in our society. We have a society in continuous learning, which requires the ability to reason in order…

This article introduces a science game which can be used for innovative teaching and as an assessment tool. The Shadow Races Game is designed for first and second grade students to learn the phenomenon of shadow through inquiry-based activities and questions that require the children to apply inferences from those activities. In this amusing board…

In this work, the first experiment ever done to determine the age of the Earth is revisited. The benefits of its application at primary and secondary school levels are presented and discussed. In particular, emphasis is placed on the advantage of facing students with the challenges that scientists have had to overcome during the past three…

Why Does It Take Longer to Boil Potatoes at High Altitudes? This column provides background science information for elementary teachers. This month's issue looks at why water boils at different temperatures at different altitudes.

The author believes that science within a primary school is there to enable children to be interested in the world around them and to help them start to understand it, getting them interested in the very basics, and pointing out things around them that they had not considered, so that they can start asking the questions 'why' and 'how' and 'what'…

The Next-Lab project provides free web-based resources supporting teachers in enhancing students' learning experiences. By including online laboratories, experiments otherwise difficult or impossible to perform are facilitated (e.g. crashing meteoroids into Earth). This article briefly presents the project and opportunities offered to teachers and…

The Australian Science Teachers Association offers an innovative international professional development program for science teachers called the Science Teachers Exchange -- Japan. The program offers Australian and Japanese teachers an opportunity to travel to the corresponding country, allowing the teachers to grow in their knowledge of the…

When carbonated beverages (which are supersaturated solutions of aqueous carbon dioxide) are confined within a narrow-necked container, events which rapidly release the gas from solution produce a fountain out of the beverage. One well-known variant of this experiment is the addition of Mentos candies to a bottle of Diet Coke. Previous reports…
