Ocean acidification (OA) has been called climate change's evil twin for a reason. Increased levels of carbon dioxide, caused by humans burning fossil fuels, are not only causing a rise in global temperature but are also having adverse impacts on marine ecosystems. In the lesson presented in this article, students conduct investigations using…

This paper provides a conceptual analysis and methodology to improve the Next Generation Science Standards' focus on interdisciplinary connections. The paper identifies a plethora of connections across Disciplinary Core Ideas that are neglected by the NGSS. In addition, it presents a methodology to generate "educative" curriculum…

Evolution can be a difficult concept for students, even though it is an organizing principle in biology. It can also be a challenge for teachers to cover evolution properly (or at all) in the classroom, whether due to personal attitudes or lack of knowledge or confidence in the material (Rutledge and Mitchell 2002). Even in some states where…

EngQuest, an initiative of Engineers Australia, provides an exciting, non-competitive way for students to participate in free, fun and educational engineering activities involving mathematics, science and technology. This article describes a project designed to teach middle school students how to construct a water catchment system. Water…

The Bold Fold, which is presented in this article, is a 45-minute activity in which students create a protein model while learning the processes of transcription, translation, protein folding, and delivery, which are often difficult to understand and have led to common misconceptions (Wright, Fisk, and Newman 2014). This activity has been used…

In this article the authors describe an Integrative Science Technology Engineering and Mathematics (STEM) Education Design-Based Learning (I-STEM ED DBL) activity that invites students to delve into the science, technology, and engineering related to the production of Ötzi's copper axe and to speculate about the circumstances surrounding his…

The "burning candle" experiment is used in middle school education programs to prove that air contains a component that is essential to burning (i.e., oxygen). The accepted interpretation taught by teachers in middle school is this: when burning occurs, oxygen is used up, creating an underpressure that causes a rise in water level inside…

This interdisciplinary scientific inquiry lesson specifically utilizes the 5E learning cycle to engage high school students in an investigation on size-dependent properties of matter. In particular, this inquiry lesson focuses on a biologically relevant phenomenon, namely accessibility to a pharmaceutical drug with respect to the size of the pill.…

As solar energy becomes increasingly affordable, many schools are considering installing new solar power systems. In this article, the authors present Solarize Your School, an engineering project that gives students the opportunity to design and evaluate solar power solutions for their own schools. This STEM project requires students to learn and…

Solar eclipses occur several times a year, but most people will be lucky if they see one total solar eclipse in their lifetime. There are two upcoming total solar eclipses that can be seen from different parts of the United States (August 21, 2017 and April 8, 2024), and they provide teachers with an amazing opportunity to engage students with a…

This practical lesson describes how students in six eighth grade science classes participated in a lesson combining the National Core Arts Standards with the Next Generation Science Standards. The goal of the lesson was to provide visual representations of finch beak form and function so students could better understand genetic variation and how…

This paper discusses a set of easy, hands-on experiments that inquire into and differentiate among tattoo inks of varying quality. A classroom scenario is described for integrating these experiments into secondary school chemistry classes. Initial experiences from the classroom are also presented.

Why are there only crumbs left at the bottom of the cereal box? Many factors, such as package handling, have caused the cereal pieces to break down into crumbs. This explanation is also related to the process of creating sediment from rocks. Sediment is created by weathering over millions of years, and it is deposited all over the world by…

A solid understanding of the structure and function of cells can help establish the foundation for learning advanced concepts in the biological sciences. The concept of the cell is introduced in middle school life science courses and is continued at the undergraduate level in college (NRC 2012; Reece et al. 2014). Cells are introduced to students…

Ocean acidification, a product of CO[subscript 2] absorption by the world's oceans, is largely driven by the anthropogenic combustion of fossil fuels and has already lowered the pH of marine ecosystems. Organisms with calcium carbonate shells and skeletons are especially susceptible to increasing environmental acidity due to reduction in the…
