Kids are drawn to dolls and dump trucks, and crashing the two together might just be a child's favorite pastime. Who knew such a simple pleasure could serve as an accessible, compelling phenomenon for instigating investigations of force and motion. With a few inexpensive materials straight out of the toy box (literally, a doll, a dump truck, a…

Primary school topics involving abstract concepts are challenging to teach. Electric circuits can be simply constructed but complex to explain. New approaches in teaching students for understanding are needed to advance practice in primary science. This paper combines the strengths of multimodality research perspectives with variation theory to…

Many simple chemical reactions produce an audible fizz due to the formation of gases, such as oxygen, hydrogen, or carbon dioxide. A hands-on activity based on perceiving these audible chemical changes is presented. The relative quality of fizz due to the formation of gases in a chemical reaction was determined by visually impaired middle and high…

Floating and sinking (FS) is a key topic in science education, both at primary and secondary levels. The interpretation of FS phenomena, however, is challenging due to the difficulty of the scientific concepts and explanatory models involved (e.g., density, buoyancy), along with students' everyday experiences, which conflict with scientific…

According to the National Survey of Science and Mathematics Education (2018), only 16% of the elementary teachers surveyed reported including hands-on activities in all or most of their lessons. Strategies that engage students in hands-on investigations help improve student achievement (Minner, Levy, and Century 2010) and provide students with a…

This article focuses on a sequence of learning experiences designed to raise children's awareness about weaving using yarn, which is one aspect of fibre and production technologies. The technologies context of the fibre production allows children to learn about the chemistry concepts related to the materials. An explicit focus on the properties…

Electricity is an integral part of daily life. Children, like adults, infer the effects of electrical conductivity. They see the illumination of a lightbulb or feel the emission of warmth from an electric stovetop but may not understand the role electrical circuits play. Focusing on the concrete aspects of electrical energy transfer helps improve…

Background: The question of the efficiency of withholding answers and the physical manipulation of material in science education has become the target of a large number of researchers (proponents of the Cognitive Load Theory) in recent years. However, no research has been found examining the contribution of these elements of teaching to the…

We describe the development, design, implementation, and preliminary classroom results of an innovative curriculum, "Focus on Energy," that supports learning about energy in Grades 4-5. The curriculum is grounded in the concepts of science as practice, model-based reasoning, and learning progressions, and builds on students' pre-existing…

The role of virtual simulations in the evolution of primary school students' mental models about electrostatics is investigated by analysing the answers of two groups of 9-10 years old pupils inside instructional sequences that combine two hands-on activities using balloons and jackets with the same activities using PhET simulations: one group…

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…

In this article, the authors present a 5E learning cycle for fifth grade that focuses on using a model of matter to explain the properties they observe, and how those properties can help identify whether two objects are made of the same type of matter. That model also helps explain phenomena such as why a specific material floats, no matter how…

A set of core ideas in the life sciences revolve around genetics, variation, and inheritance. While the "Next Generation Science Standards" (NGSS; NGSS Lead States 2013) emphasize teaching and learning about these concepts across K-12 grades, it is critical for early learners to begin to develop understanding of them. By the end of fifth…

This article describes a lesson rooted in "tinkering," an approach to learning that encourages the use of authentic, hands-on experience to develop an understanding of content and physical materials. There were several desired outcomes for this lesson. First, the authors felt that tinkering was an appropriate approach to investigating…

By bringing everyday phenomena into the classroom, teachers can more readily engage students in authentic scientific inquiry. When working with young children, the best phenomena are those that students can directly experience and investigate. Meaningful phenomena can be identified by watching children at play, listening to the conversations they…
