Harlow, Danielle; Hansen, Alexandria – Science and Children, 2018
The Maker Movement (Dougherty 2012) highlights innovation and creativity through "activities focused on designing, building, modifying, and/or repurposing material objects, for playful or useful ends, oriented toward making a 'product' of some sort that can be used, interacted with, or demonstrated" (Martin 2015, p. 31). When engaged in…

Wang, Bo; Lin, Zhiqiang; Wang, Min – Journal of Chemical Education, 2015
Paper-based microfluidic devices (µPAD) are a burgeoning platform of microfluidic analysis technology. The method described herein is for use in undergraduate and high school chemistry laboratories. A simple and convenient µPAD was fabricated by easy patterning of filter paper using a permanent marker pen. The usefulness of the device was…

Brown, Patrick L.; Concannon, James; Hansert, Bernhard; Frederick, Ron; Frerichs, Glen – Science Activities: Classroom Projects and Curriculum Ideas, 2015
Why does a balloon deflate when it is left in a cold car; or why does one have to pump up his or her bike tires in the spring after leaving them in the garage all winter? To answer these questions, students must understand the relationships among temperature, pressure, and volume of a gas. The purpose of the Predict, Share, Observe, and Explain…

Ward, Lauren; Lyden, Sarah; Fitzallen, Noleine – Australian Mathematics Teacher, 2016
Context based learning (CBL) is a powerful tool that utilises areas of student interest framed in meaningful contexts to foster development of new skills and understanding. For middle school students, engineering activities that relate to real-world problems provide suitable CBL contexts for acquiring conceptual scientific and mathematical…

Kao, Jacqueline Y.; Yang, Min-Han; Lee, Chi-Young – Journal of Chemical Education, 2015
Neo magnets are neodymium magnet beads that have been marketed as a desktop toy. We proposed using neo magnets as an alternative building block to traditional ball-and-stick models to construct carbon allotropes, such as fullerene and various nanocone structures. Due to the lack of predetermined physical connections, the versatility of carbon…

Feng, Z. Vivian; Edelman, Kate R.; Swanson, Benjamin P. – Journal of Chemical Education, 2015
Flow synthesis in microfluidic devices has been rapidly adapted in the pharmaceutical industry and in many research laboratories. Yet, the cost of commercial flow reactors is a major factor limiting the dissemination of this technology in the undergraduate curriculum. Here, we present a laboratory activity where students design and fabricate…

Andraos, John – Journal of Chemical Education, 2015
This paper presents a simplified approach for the application of material efficiency metrics to linear and convergent synthesis plans encountered in organic synthesis courses. Computations are facilitated and automated using intuitively designed Microsoft Excel spreadsheets without invoking abstract mathematical formulas. The merits of this…

Hudson, Reuben; Glaisher, Samuel; Bishop, Alexandra; Katz, Jeffrey L. – Journal of Chemical Education, 2015
A multiple day activity for students to create large-scale plastic objects from the biopolymer chitin (major component of lobster, crab, and shrimp shells) is described. The plastic objects created are durable and made from benign materials, making them suitable for students to take home to play with. Since the student-created plastic objects are…

Hoffman, Adam; Turner, Ken – Journal of Chemical Education, 2015
A multipart laboratory activity introducing microbeads was created to meet engineering and engineering design practices consistent with new Next Generation Science Standards (NGSS). Microbeads are a current topic of concern as they have been found to cause adverse impacts in both marine and freshwater systems resulting in multiple states proposing…

Priano, Christine – American Biology Teacher, 2013
This model-building activity provides a quick, visual, hands-on tool that allows students to examine more carefully the cloverleaf structure of a typical tRNA molecule. When used as a supplement to lessons that involve gene expression, this exercise reinforces several concepts in molecular genetics, including nucleotide base-pairing rules, the…

Sandoval, Christopher – Teaching Science, 2012
Plain flour has a lot of chemical energy packed into it. When the flour is in a clump or pile it does not ignite although it may blacken. This is because there is not enough flour exposed to the oxygen in the air. Aerosolising the flour exposes it to much more oxygen allowing a self sustaining combustion reaction to occur when an ignition source…

Christensen, Doug – American Biology Teacher, 2013
Understanding how DNA banding patterns in a gel can aid in the conviction or exoneration of suspects and be utilized for positive identification of biological fathers in paternity cases can be intimidating. In reality, the logistics and technology used in such cases are rather straightforward. This exercise is designed for use in high school…

Michael, Kurt Y. – Technology and Engineering Teacher, 2013
The "Titanic" caught the attention and imagination of the public when, in 1985, the sunken ship was discovered 370 miles off the coast of Newfoundland (PBS, 2012). Since that time, scientists have conducted numerous expeditions using high-resolution SONAR working in tandem with remote-operated vehicles (ROV) to collect information used…

Falteisek, Lukáš; Cerný, Jan; Janštová, Vanda – American Biology Teacher, 2013
To involve students in thinking about the problem of AIDS (which is important in the view of nondecreasing infection rates), we established a practical lab using a simplified adaptation of Thomas's (2004) method to determine the polymorphism of HIV co-receptor CCR5 from students' own epithelial cells. CCR5 is a receptor involved in inflammatory…
