This article describes the use of project-based instruction in activities and labs intended to develop higher-order thinking skills with high school students and pre-service teachers through the use of soap making.

The project team gathered data with the assistance of Recreational and Cultural Organization of Mashhad Municipality, Organization of Mashhad Municipality and Science and Astronomy Science Center of Mashhad Municipality, Khorasan Razavi, Islamic Republic of Iran. This paper discusses the effect of science center on attitude of students who visit…

The maker movement consists of a growing culture of hands-on making, creating, designing, and innovating. A hallmark of the maker movement is its do-it-yourself (or do-it-with-others) mindset that brings individuals together around a range of activities, both high- and low-tech, all involving some form of creation or repair. The movement's…

Understanding how the periodic table of elements is organized and how to read information from it is fundamental for understanding chemistry. Introductory chemistry courses usually include discussions detailing what elemental information can be determined by virtue of its position on the periodic table. Although many people have been exposed to…

Project-based learning and interdisciplinary projects present an opportunity for students to learn both technical skills and other skills which are relevant to their workplace success. This paper presents an assessment of the educational impact of the OpenOrbiter program, a student-run, interdisciplinary CubeSat (a type of small satellite with…

Development of an effective strategy for promoting science education and professional development of K-12 science educators is a national priority to strengthen the quality of science, technology, engineering, and mathematics (STEM) education. This article reports the outcomes of a Geoscience Professional Development Program (GPDP) workshop…

This study stemmed from concerns among researchers that reform efforts grounded in promoting inquiry as the basis for teaching science have not achieved the desired changes in American science classrooms. Many science teachers assume that they are employing inquiry-based strategies when they use cookbook investigations with highly structured…

Tech Trek opens up STEM possibilities for girls in many contexts. It expands and influences their academic and social lives, starting in middle school and continuing on into their careers. The program seeks out talented girls, sparks their interest, illuminates the value of a college education, and validates their passions. Tech Trek's exciting,…

After agreeing to host over 200 students on a daylong genetics field trip, the author needed an easy-to-prepare genetics experiment to accompany the DNA-necklace and gel-electrophoresis activities already planned. One of the student's mothers is a pediatric physician at the local hospital, and she suggested exploring genetic-disease screening…

A laboratory experiment is described to determine the primary current distribution in parallel-plate electrochemical reactors. The electrolyte is simulated by conductive paper and the electrodes are segmented to measure the current distribution. Experiments are reported with the electrolyte confined to the interelectrode gap, where the current…

Nanoporous zeolite foam is an interesting crystalline material with an open-cell microcellular structure, similar to polyurethane foam (PUF). The aluminosilicate structure of this material has a large surface area, extended porosity, and mechanical strength. Owing to these properties, this material is suitable for industrial applications such as…

When doing spring planting activities, what does a teacher do while waiting for the plants to grow? This waiting time is a golden opportunity to explore another side of gardening--the creatures that make it all possible. Insects are an integral part of everyday world, having existed for over 300 million years; they are the most common animal on…

A cost-effective, hands-on laboratory exercise is described for demonstrating nanoscale fabrication at non-research-based educational institutions. The laboratory exercise also contains a component involving qualitative and quantitative surface characterization of student-fabricated nanoscale structures at institutions with on-site access to an…

Because educators vicariously touch the future through their students, the author believes that they sometimes have the uncanny ability to see the future. One common future forecast is the phenomenal growth of green jobs in the emerging green economy, leading to the creation of the "Reach of the Sun" Solar Energy Academy at La Mirada…

One of the author's biggest challenges as a preschool teacher is helping children in a group see and touch and do. Hands-on explorations are important for everyone, but essential for young children. How can young children do hands-on explorations of spiders and their webs? Teachers do not want children handling all sorts of spiders. They worry…
