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…

Although science, technology, engineering, and mathematics (STEM) initiatives have received increased attention in recent years (Bybee 2011), the focus is often on science and mathematics (Thornburg 2009). Yet, engineering has been referred to as "the glue that holds the other STEM subjects together" (Thornburg 2009). With the release of…

Teachers have the daunting task of preparing students for a future that they cannot predict. In an age of information where students have the world quite literally at their fingertips, and with the ever-growing momentum of integrated science, technology, engineering, and mathematics (STEM), it is not enough that students experience STEM subjects…

Picture this: a PhD chemist, PhD science educator, and a preservice Latina elementary educator walk into an aftercare program for primary and intermediate students from a rural school. These students are identified as low income and at risk and therefore eligible to participate in this school-provided aftercare. While across the state, these same…

Because students have often been conditioned as passive learners and receivers of knowledge, it can be difficult for them to persevere in solving authentic problems. Nevertheless, teachers must persist in preparing students as problem solvers and critical thinkers. In an urban inner-city neighborhood school in the southeast, students embarked on a…

In this article, Mann and Pynes describe a five-day mini-project-based learning (PBL) unit about organisms and their environments that addresses the "Next Generation Science Standards" (3-LS4-3). Third-grade students were asked how they could determine which animals live in their neighborhoods. In teacher-determined collaborative groups,…

Structural engineering can be a rich and exciting context for exploring and learning about the properties of materials. Even a structure as commonplace as a house requires careful consideration of important properties such as strength, stability, and insulation. As a former engineer and current elementary science teacher educator, the author has…

Problem-based learning (PBL) is one approach to teaching science that supports the notion that students construct knowledge within contextual settings, and that critical thinking and application are best fostered within these realistic contexts. In other words, learning activities are best applied when they are authentic or embedded in real-life…

The authors combined content-driven and inquiry-based lessons into the framework of problem-based learning (PBL). They did this in eight third- through sixth-grade classrooms--two each from grades 3-5, one from sixth grade, and one mixed-grade special education. These older elementary students explored a local problem of lobsters infected by…

With the 2010 Winter Olympic Games prominent in the media, children were exposed to images of athletes skiing down snow-covered slopes, coasting furiously on bobsleds, and skating gracefully across the ice. Therefore, the authors capitalized on their children's natural curiosity about the world around them by exploring the concept of motion in a…

"Watch out, the stove will burn you," "Ooh, ice cream headache!" Students construct their conceptions about heat and temperature through their own intuitions about daily life experiences. As a result, misconceptions can be born from these constructed concepts. The activity described here addresses student misconceptions about thermal insulation…

"On your mark, get set, go!" Elementary students love to hear these words as they participate in the annual Third Grade Better Boat Challenge. This highly motivational project started a few years ago as the author was developing the third-grade science curriculum to include a study that revolved around models, design, and problem solving. It has…

Science centers can engage students; accommodate different learning styles and individual interests; help students become independent and confident learners; and encourage social skills among students. In this article, the author worked with third-grade students as they completed activities at learning centers during a week-long unit on simple…

Imagine--you must bring water to a hurricane-ravaged area. There is only one bridge and only one truck, and the bridge can only hold so much weight. Your calculations determine if the truck--and its load of water--can make it safely over the bridge. This is a typical challenge during two-week summer camps for third-through fourth-grade students…
