It is becoming increasingly important for students to go beyond engaging in design by reflecting upon the nature of engineering (NOE) and wrestling with questions such as, "What do engineers do?" and "What is engineering?" This article describes an activity in which middle school students are asked to create a product to help a…

Although nearly everyone is familiar with colors from an early age and the fundamentals of color mixing are taught at various abstraction levels throughout kindergarten to high school, we repeatedly observe that our student teachers in physics have problems in explaining the subject. Therefore, we propose an experimental setup that focuses on the…

Conrad Hal Waddington (1905--1975) was an English biologist who was especially interested in the big (metaphysical) questions of life. His thinking has become part of the foundation of modern systems biology. This article applies his thinking to middle-years school biology curricula (for ages 11-16), to see if their approach to epistemic questions…

Over the past several decades it has become increasingly important to understand nature of science (NOS) for scientific literacy in science education. Science education researchers have suggested using socio-scientific issues to create a context for that purpose. The present fast-moving coronavirus or COVID-19 pandemic as a socio-scientific issue…

What better way to engage fifth-grade students in science and engineering practices than to use paper airplanes to encourage them to question, explore, create, and test designs! This multi-day unit draws from a fourth-grade curriculum (Pearson 2012) aligned with the "Next Generation Science Standards" (NGSS Lead States 2013) used in…

Teaching about drawbridges allows students to apply skills they have learned in math and science, while also being creative with design and the use of available materials. Students can be exposed to current and ancient designs. Today's drawbridges are beginning to look their age and are in need of updating and modernization. New bridges are being…

A "Framework for K-12 Science Education and the Next Generation Science Standards" ("NGSS") are intended for all students, hence "all standards, all students" (NGSS Lead States 2013). To make this vision a reality, the "NGSS" highlight three key instructional shifts: (1) explain phenomena or design solutions…

This column presents ideas and techniques to enhance your science teaching. This month's issue shares information on how students' everyday experiences can support science learning through engineering design. In this article, the authors outline a reverse-engineering model of instruction and describe one example of how it looked in our fifth-grade…

Helping students understand that the scientific community's claims change through time, sometimes radically, allows them to develop a well-grounded sense of the "nature of science." Learning to reason about how scientific claims come to be accepted, and later refuted, is important for understanding the tentative nature of scientific…

Next Generation Science Standards (NGSS), with new emphasis on engineering, reflects broadening definitions of scientific and technological literacy. However, engaging in science and engineering practices is necessary, but insufficient, for developing technological literacy. Just as robust scientific literacy includes a deep understanding of the…

Language is the way students and teachers communicate in the science classroom, but language of science is not always the language children and adults use in their everyday life. As Michaels, Shouse, and Schweingruber put it, "In science, words are often given specific meanings that may be different from or more precise than their everyday…

Mathematics and science are natural partners. One of many examples of this partnership occurs when scientific observations are made, thus providing data that can be used for mathematical modeling. Developing mathematical relationships elucidates such scientific principles. This activity describes a data-collection activity in which students employ…

The National Assessment of Educational Progress (NAEP) measures student science achievement nationally, state by state, and, most recently, across selected urban school districts. Periodically, the framework underlying the science assessment is revised or updated. This document, "Science Framework for the 2019 National Assessment of…

As institutions, science and science education alike have rarely included the perspectives and contributions of indigenous peoples pertaining to the natural world. Yet, people worldwide have benefited from the traditional ecological knowledge of indigenous communities. Western science and technology, though broadly worthwhile, have been a source…

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…
