Previous articles in "Primary Science" have presented a range of ways to teach electricity in engaging and informative ways (e.g. Buckley and Harvey, 2014; Chapman, 2014; Norman, 2014; CLEAPSS, 2016) and Frank Harris provides an interesting historical account of the development and use of batteries in "School Science Review"…

This article details the development of design principles to support teachers in planning for a Community-Based Mathematical Modeling task with a focus on social justice in the elementary grades. By reflecting on the dilemmas we encountered in the design and enactment of the tasks, we developed five design principles that allowed us to address…

The aim of this article is to present a case study in the field of ESD for in-service teachers training conducted in a Swiss primary school. A Discursive Community of Interdisciplinary Practices (DCIP) has been created including researchers, teachers, and a pedagogical advisor in the context of ESD, focusing on the topic of chocolate. In this…

When it comes to winning the hearts of children, it is sometimes hard for plants to compete. How do teachers make plants exciting for children? The answer lies in the ancient practice of hydroponics. Hydroponics may seem like complicated, cutting-edge technology, but, in fact, it has been around for centuries. Using hydroponics in the classroom…

Easy-to-use classroom resources that support science teaching are always welcomed by time-poor teachers. Ideally these resources should be easy to find, useful and have the flexibility to be incorporated with minimal adaptation into an already full teaching day. Using food in the classroom is certainly not a new idea--especially for primary school…

Herbivores are important to ecosystems because they transfer energy stored in plant matter to other organisms. However, when herbivores occur in high abundances, they can become pests and harm the plants that form the basis of food webs. Mangroves are saltwater tolerant trees found along most tropical and subtropical shorelines. Because mangroves…

Tootsie Pops, manufactured by Tootsie Roll Industries of Chicago, Illinois, are spherical hard-candy lollipops with a chocolate-flavoured, chewy center. While Tootsie Pops have been around since 1931, it was a television commercial made in 1969 that captured the attention of many. The commercial, an amusing animated cartoon, posed the following…

Engineering is an intriguing way for students to connect the design process with their knowledge of science (NRC 2012). This article describes the "Engineering a Pancake Recipe" design process which was created to make the structure and properties of matter more meaningful for fifth grade students. The whole pancake recipe engineering…

For the last several years, the authors have implemented an integrated Mars Colony project for their third-grade classes. Students explored several considerations related to colonizing and inhabiting a new world, including food sources, types of citizens, transportation, and housing design. Nearly everything about the project was open-ended, full…

In this article, Claas Wegner, Phillip Weber, and Stephanie Ohlberger share how they have been teaching about variation and staple food crops in the teaching unit they tested with 8- to 10-year-old children. They started by showing some products made from crop plants and asking the class to carry out a simple comparison of similarities and…

Severe flooding was prevalent within the authors' region at the beginning of the school year. Many homes and fields were affected by the amount of rain that fell within a short period of time over multiple days. Their students were concerned about the impact this natural phenomena was having on their local community. Natural phenomena can provide…

In recent years, many schools have taken up food gardening. This is a welcome trend, but it has had to be conducted as an extracurricular activity, often with the help of, or run by, parents and grandparents. Growing vegetables and fruit, if it is to be done well, is a complex activity. The potential good outcomes for health, learning, and…

Planning for and teaching somebody else's class can be a daunting process, especially for a trainee teacher like the author, who still has to gain all the knowledge and experience of managing a group of 36 10- and 11-year-olds. As part of her degree studies, the author had to plan, with a group of other trainee teachers, a series of lessons on…

In this article, the authors discuss a special type of multiplication-and-division-of-fractions problem that elementary school teachers can use to promote children's understanding of fractional quantities and their relationships. These problems are accessible to students working at different levels of fraction understanding, and they can be solved…

An introduction to microscopy is common in the elementary curriculum, but microscope work with elementary school children can be a challenge. There is equipment maintenance to consider, as well as the difficulty of using the microscope for many children. These authors have found that using a digital microscope connected to a projector breaks down…
