Artificial photosynthesis is a promising approach to generate commodity chemicals using abundant chemical feedstocks and renewable energy sources. Despite its importance, affordable and effective hands-on classroom activities that demonstrate artificial photosynthesis and teach key concepts, especially for primary school students, are lacking.…

The use of digital technologies as teaching and learning materials supports and enhances science learning, encouraging students to develop valuable inquiry skills and knowledge. In response, this paper seeks to explore digital inquiry-based learning as a useful aid for teaching the elementary school science curriculum on plants in Malaysia. There…

In this article, a low-cost and pocket-sized setup for measuring CO[subscript 2] is presented. This setup is based on Arduinos, making it economic and open to modifications or improvements that satisfy other needs. It is composed of an Arduino board, a CO[subscript 2] sensor, an SD-card module, and a control panel. The device has been tested in…

The diet of many students consists of on-the-go processed food. As part of a larger school garden project, the authors wanted students to consider the relevance of plants in their own lives, both as food sources for us and for the animals that we eat. In this article, they present a mini-unit they taught in a third-grade classroom that helped…

This article addresses how we can develop learning environments that establish a need for scientific practices and provide a context for developing content knowledge through practice. It argues that Pickering's (1995) notion of "The Mangle of Practice" informs these efforts by focusing our attention on how resistance, or push-back from…
