The NGSS MS-ETS1 Engineering Design (1-4) is the focus of the article. Development of a challenging problem-based activity that is an improvement over the traditional egg drop competition is emphasized. Quantification of data collected and real-world relevance are two activity components that are viewed as improvements over the egg drop. The…

This article is the second in "Teaching Science's" "Try This" series. These hands-on activities are designed especially for early childhood students to encourage their natural curiosity and promote development of scientific thinking. In this activity, the problem-based learning approach means that the children are engaged in a…

A laboratory experiment was developed to enable students to investigate the use of smart hydrogels for potential application in targeted drug delivery. This is challenging for students to explore practically because of the extremely high risks of handling cross-linking agents such as glutaraldehyde. Genipin is a safe and green alternative that has…

Laboratory-based practical classes are a common feature of life science teaching, during which students learn how to perform experiments and generate/interpret data. Practical classes are typically instructional, concentrating on providing topic- and technique-specific skills, however to produce research-capable graduates it is also important to…

The power of 3D printing technology has grown exponentially in just the past few years--people around the world are using 3D printers to prepare food, create tailored clothing, build cars and homes, and advance the medical field in ways that never seemed possible. In classrooms across the nation, 3D printers have become increasingly common because…

In a regional gathering called the Youth Water Summit, high school students present projects that respond to the driving question behind their science curriculum: "How can you address a significant water resource challenge in your community's watershed?" Students exhibit scientific posters, interactive presentations, films, art projects,…

A Project Based Learning (PBL) methodology was used in the practical laboratories of the Advanced Physical Chemistry department. The project type proposed simulates "real research" focusing on sol-gel synthesis and the application of the obtained sol as a stone consolidant. Students were divided into small groups (2 to 3 students) to…

A series of qualitative analysis (QA) laboratory experiments utilizing a problem-based learning (PBL) module has been designed and implemented. The module guided students through the experiments under the guise of cleaning up a potentially contaminated water site as employees of an environmental chemistry laboratory. The main goal was the…

This article describes a cooperative project between eighth graders and first graders called "Going Green in the Neighborhood." The project entailed the first grade students sketching home designs on paper to make a model community, and the eighth grade students taking those drawings and making them into 3D computer models and then…

This article describes an after-school program at the Horace Mann School for the Deaf (HMS), the oldest public day school for deaf students in the United States, where almost half of the student body imagined and created bridge and robotic machines. The Deaf Robotics Engineering and Math Team, or the DREAM Team club, included HMS students in…

By the 1970s a fundamental shift had taken place in German science education. This was a shift away from the learning of more-or-less isolated facts and facets in Biology, Chemistry, and Physics towards a restructuring of science teaching along the general principles of the respective science domains. The changes included also the addition of…

Attempts at integrating mathematics and science have been made previously but no definitive, widely adopted teaching model has been developed to date. Research suggests that hands-on, practical, student-centred tasks should form a central element when designing an effective model for the integration of mathematics and science. Aided by this…

This paper discusses a K-12/university collaboration in which students participated in a four-day scenario-based summer STEM (science, technology, engineering, and mathematics) camp aimed at making difficult scientific concepts salient. This scenario, Jumpstart STEM-CSI: Chocolate Science Investigation (JSCSI), used open- and guided-inquiry…

The Hudson River Watershed contains a variety of geologic, topographic, climatic, and hydrologic features and a diversity of land-use patterns--making it an ideal model for studying human impact on the coastal environment. In this article, the authors present the Hudson River Plume (HRP), a problem-based online module that explores nonpoint-source…

One challenge that middle school teachers commonly face is finding insightful, hands-on applications when teaching basic mathematical concepts. One concept that is a foundation of middle school mathematics is the notion of "linear functions." Although a variety of models can be used for linear equations, such as temperature conversions,…
