This lesson focuses specifically on teaching concepts of speed and its impact on energy, as well as providing a basic introduction to potential and kinetic energy to fourth-grade students. "Next Generation Science Standards" ("NGSS") 4-PS3-1 states that students should be able "to use evidence to construct an explanation…

Science and engineering practices (SEPs) and crosscutting concepts (CCs) constitute a significant part of "A Framework for K-12 Science Education" (NRC 2012). As teachers, the role of the authors is to highlight the pivotal role that both scientific knowledge and the practices used to generate knowledge play in learning. This article…

The 2017 Total Solar Eclipse (TSE2017) will occur on August 21 in the continental United States, bringing totality to this area for the first time since 1979. The Moon's umbra will traverse from Oregon to South Carolina in about 90 minutes, bringing an eerie darkness to 14 states coast-to-coast and a partial eclipse to every part of the country…

The "Next Generation Science Standards" ("NGSS") state that by the end of fifth grade, students are expected to understand the water cycle, also called the hydrologic cycle, and the three states of matter in which water can exist (NGSS Lead States 2013). Logically, many educators choose to teach these topics concurrently or…

Cunningham and Lachapelle (2011) found that most students have a naive understanding of the field of engineering, mistaking it for the work of technicians or artisans and neglecting to see the contributions engineers make to people's daily lives. In general, public (and teacher) understanding is not much more refined. These misconceptions about…

Children understand the natural world in ways that make sense to them before they learn any science in school. This column provides ideas and techniques to enhance science teaching. This month's issue helps students connect scientifically correct ideas to what makes sense to them.

Kindergarten students have an amazing capacity for wonder and inquisitiveness--two important characteristics for future scientists. Much of what young students "know" about the natural world stems from their daily interactions with peers, adults, the outdoors, and the media. What can be especially challenging to uncover and redirect are…

Not only is science perceived by some as a hard-to-teach subject, but there are certain topics that all teachers regard as notoriously hard to teach. While their natural inclination may be to eliminate some of the details, teachers have to be careful not to water down the curriculum. How do they share the complexity of the natural world without…

As children develop misconceptions about animals they believe are dangerous, they also adopt attitudes that are difficult to change. Changing these attitudes is challenging for teachers. One animal that is easy to find but difficult for children to understand is a spider. As with most wild animals, they are difficult to teach about because…

Formative assessment probes are effective tools for uncovering students' ideas about the various concepts they encounter when learning science. They are used to build a bridge from where the student is in his or her thinking to where he or she needs to be in order to construct and understand the scientific explanation for observed phenomena.…

A "Framework for K-12 Science Education"'s disciplinary core idea PS1.A states that students should know by the end of grade 2 that different kinds of matter exist and many of them can be solid or liquid, depending on temperature (NRC 2012). By the end of grade 8, they describe solids, liquids, and gases by the arrangement and…

Being able to distinguish between physical and chemical changes of matter is a foundational chemistry concept that at first seems like a simple elementary concept to teach, but students often have misconceptions that hinder their understanding. These misconceptions are seen among elementary students, but these ideas are perpetuated throughout…

The American Association for the Advancement of Science (AAAS 1993) states that by the end of fifth grade, students should understand that a model, such as those depicting the solar system, is a smaller version of the real product, making it easier to physically work with and therefore learn from. However, for students and even adults,…

Early-formed preconceptions can be explained by one of the intuitive rules identified by Stavy and Tirosh (2000) called "More A-More B". By starting with students' preconceptions, revealed through the use of a formative assessment probe, teachers can scaffold inquiry-based experiences that will confront children with their misconceptions and guide…

Formative assessment probes are used not only to uncover the ideas students bring to their learning, they can also be used to reveal teachers' common misconceptions. Consider a process widely used in inquiry science--developing hypotheses. In this article, the author features the probe "Is It a Hypothesis?", which serves as an example of how…
