Misconceptions about sinking and floating phenomena are some of the most challenging to overcome (Yin 2005), possibly because explaining sinking and floating requires students to understand challenging topics such as density, force, and motion. Two scientific principles are typically used in U.S. science curricula to explain sinking and floating:…

This article addresses misconceptions surrounding the Coriolis force and describes how it should be presented as a function within inertial and noninertial frames of reference. Not only does this demonstrate the nature of science as it strives to best interpret the natural world (and presents alternative explanations), but it offers a rich…

Nothing brings out the best in eighth-grade physical science students quite like an engineering challenge. The wind turbine design challenge described in this article has proved to be a favorite among students with its focus on teamwork and creativity and its (almost) sneaky reinforcement of numerous physics concepts. For this activity, pairs of…

Using "hands-on" instruction in the science classroom has obvious value for both teachers and students. However, just because a type of instruction does not allow students to physically interact with objects does not mean it is not worthwhile. One method the author has found to be productive and engaging for students uses examples of historical…

During a recent unit on characteristics of animals in different environments, "backyard safari" trips around the schoolyard provided opportunities for students to describe ways that animals are adapted to their unique environments. This led to a discussion of how polar bears have adjusted to living in the arctic. Therefore, students' questions…

In the atmosphere or on the ground, snow provides students with unique opportunities to discover winter weather patterns. Traditionally, when students study weather, it is limited to the collection of data one would see on a weather report. However, the interdisciplinary Students Synthesizing Snow data in Natural Objective Ways (SSSNOW) project…

Although in some schools cell phones have to be turned off or perhaps kept in lockers to avoid misuse, the authors hope to demonstrate in this article how they can be used under supervision to assist learning. This ubiquitous device can be a powerful classroom tool. (Contains 2 figures.)

What do the ideas of Daniel Bernoulli--an 18th-century Swiss mathematician, physicist, natural scientist, and professor--and your students' next landing of the space shuttle via computer simulation have in common? Because of his contribution, referred in physical science as Bernoulli's principle, modern flight is possible. The mini learning-cycle…

Studying the Olympic sport of curling is a fun and engaging way to learn about the concepts of friction, forces, momentum, and Newton's laws. Each winter, the author takes her eighth-grade physical science class on a field trip to experience curling firsthand. This field trip has become a favorite of the eighth graders at Capitol Hill Day School…

In order to fully understand student learning, we science teachers need to know the ideas that students bring into the classroom. Plus, good assessment calls for ongoing evaluation of students' progress and difficulties with learning on an everyday basis. Cartoons are one tool that has been used successfully as a means of assessing student…

Explosions and fires--these are what many students are waiting for in science classes. And when they do occur, students pay attention. While we can't entertain our students with continual mayhem, we can catch their attention and cater to their desires for excitement by saying, "Let's make rockets." In this activity, students make simple, reusable…

Many of the skills and talents required to be a successful scientist, such as analysis, experimentation, and creativity, can be developed and reinforced through art. Both science and art challenge students to make observations, experiment with different techniques, and use both traditional and nontraditional methods to express their ideas. The…

Throughout our lives we are surrounded by sounds in our environment. Our ability to hear plays an essential part in our everyday existence. Students should develop an understanding of the role technology plays in personal and social decisions. If we are to meet these goals we need to integrate aspects of responsible behavior toward hearing health…

Several teachers from State College (Pennsylvania) Area School District became intrigued with helping their students better understand the science associated with a unit on air and aviation. In particular, they observed that students often encountered difficulty with abstract flight concepts, such as lift, thrust, and drag. Content issues became…

Storytelling is an age-old and powerful means of communication that can be used as an effective teaching strategy in the science classroom. This article describes the authors' experiences implementing the Storyline Approach, an inquiry-based teaching method first introduced by Kieran Egan (1986), in the context of teaching the concept of air…
