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…

Early experiences with planning and guiding children's learning can be exciting for preservice teachers in undergraduate teacher training programs. In this article, observations of a preschool play session guide four preservice teachers to design a series of play-centered lessons addressing serious science concepts (Hall 2010). While the concepts…

The "Next Generation Science Standards" ("NGSS") and current research in science education call for students to participate in making sense of scientific experiences by building explanations from evidence collected during these experiences. One way this goal can be achieved is through rigorous classroom discussions. In this…

The integrated STEM activity described in this article incorporated two investigations that sought to develop children's understanding of fair-testing: (1) the first parachutes: how does the angle of a parachute frame affect the speed of descent?; and (2) modern parachutes: how does the size of the parachute canopy affect the speed of descent?…

Blowing bubbles is not only a favorite summer activity for young children. Studying bubbles that are grouped together, or "foam," is fun for children and fascinating to many real-world scientists. Foam is widely used--from the bedroom (mattresses) to outer space (insulating panels on spacecraft). Bubble foam can provide children a…

Earth and space science deserve the same level of inclusion in early childhood curriculum as the other science disciplines, and research shows that the sooner children are introduced to concepts like those presented in planetarium programs, the stronger their lifelong interest in science will be. Much astronomy visualization outside of…

With their sunny stripes and fuzzy bodies, bees are beloved--but unfortunately, they are in trouble. Bee decline, of both wild bees as well as managed bees like honey bees, has been in the news for the last several years. Habitat loss, diseases, pests, and pesticides have made it difficult for bees to survive in many parts of our world (Walsh…

Children naturally delight in the sounds created with their bodies, including their own shrieks and shrills. On the playground and in the classroom, young children fill the air with stories, mimicked animal and car sounds, word games, and songs. Babies are aware of their basic cries of hunger and more developed babbling. Ears and brains constantly…

Scientific investigations are usually introduced to children by referring to phenomena and occurrences that they already know about from their environment. The goal is that children learn to understand everyday observations and experiences from a scientific perspective, pose questions, express and test simple hypotheses by planning and performing…

Teaching students to make daily weather observations is one way educators assist them as they learn to dress appropriately. In addition, it provides a natural and developmentally appropriate link between science and other curriculum areas, such as literacy and language development. The "Next Generation Science Standards" (NGSS Lead…

This article describes how observing whether objects sink or float in water using the P-E-O (Predict, Explain, and Observe) technique is an elementary precursor to developing explanations in later grades that involve an understanding of density and buoyancy. Beginning as early as preschool, elementary students engage in activities that encourage…

Students have a difficult time understanding force, especially when dealing with a moving object. Many forces can be acting on an object at the same time, causing it to stay in one place or move. By directly observing these forces, students can better understand the effect these forces have on an object. With a simple, student-built device called…

This column focuses on promoting learning through assessment. This month's issue uses concept cartoons to assess students' ideas about the moon. Concept cartoons, formative assessment tools that reveal students' preconceptions and probe for conceptual understanding, have recently become popular in the United States, with teachers…

With crosscutting concepts such as stability and change in the "Next Generation Science Standards," this article was written for those who have wondered how to teach these concepts in a way that is relevant to students. In this investigation, students ask the question, "Why is the pond dirty?" As students investigate the health…

Of the eight scientific practices highlighted in "A Framework for K-12 Science Education: Practices, Crosscutting Concepts, and Core Ideas," the first is for students to develop abilities to ask questions and define problems (NRC 2012). Constructing a range of questions about an object or phenomenon validates not only what students have…
