The interaction between water and surfaces is observed in our daily lives and is used in laboratories to study materials properties, such as interfacial tension. Making the connection between fundamental scientific phenomena and everyday observations is a powerful method of highlighting the importance and relevance of science to the K-12…

This article describes how one teacher introduced Earth science topics to a 10th-grade biology class using a 3D printer. The activities described give students opportunities to visit Earth's geologic landmarks through kinesthetic modeling. 3D-printed topographical maps function as a supplement to, or replacement of, two-dimensional drawings,…

In this paper, we present the details of the development of a smartphone spectrometer for education using a 3D printer and characterized the performance by comparison with a paper craft spectrometer. The optical design and the narrow slit used in the build resulted in the formation of accurate images of the slit on the image sensor leading to a…

Microscopes are especially useful for observing fine detail in biological specimens. However, there are many other small items that may be examined with microscopes, and it is important to introduce children to low-magnification images of items they can recognise before moving on to such large magnification that what they observe has no obvious…

Lessons and homework problems involving a pendulum are often a big part of introductory physics classes and laboratory courses from high school to undergraduate levels. Although laboratory equipment for pendulum experiments is commercially available, it is often expensive and may not be affordable for teachers on fixed budgets, particularly in…
