In today's science classes, where standards are shifting toward engaging in scientific practices, a shift in science assessments to better reflect the skills and knowledge achieved in modern science classrooms is needed. If science is a discipline to be practiced rather than memorized, then science assessments should be designed to gauge a…

Embedding science learning in real-world issues is a research-based way to generate student enthusiasm, interest, and motivation for science. The authors advocate teaching secondary science in the context of "socio-scientific issues" (SSI). SSI are authentic societal challenges with connections to science, such as climate change,…

The "electric grid" is the system of power generators, power lines, and other equipment that transports electricity from where it is generated to where it is used. Electricity and its distribution are crucial to the functioning of modern society, yet its dynamics often go unseen and unnoticed by the public. Teaching about the sources…

In March of 2020, the world of education was upended. Teachers and students across the globe abruptly left their classrooms. Once taught in abstraction, science concepts became national headlines, no longer relegated to textbooks. Misinformation began spreading faster than any virus, and for many science teachers, addressing scientific untruths…

The use of large, open-source data sets is ubiquitous in scientific research. Scientists--ranging from meteorologists to chemists to epidemiologists--are researching and investigating critical questions using data that they have not themselves collected. To contribute to the growing effort to bring data science into classrooms, the authors have…

Polychlorinated biphenyls (PCBs) are a family of synthetic chemicals consisting of carbon, hydrogen, and chlorine atoms. PCBs have been produced commercially since 1929 in hundreds of industrial applications. Their continued production in the United States was phased out in the late 1970s, and strict disposal guidelines were regulated as adverse…

The science and engineering practices in the "Next Generation Science Standards" seek to engage students in complex tasks including planning and carrying out investigations or engaging in argument from evidence. However, such tasks often require students to effectively collaborate. While our students get better at working together in an…

In this secondary-level lesson, students will generate and prioritize questions about the novel coronavirus and evaluate scientific and/or technical information from multiple authoritative sources, assessing the evidence and usefulness of each source for answering their prioritized questions. This lesson consists of three segments: (1) connecting…

Underrepresentation is endemic across disciplines and across time (National Science Foundation 2019), and extensive research clearly shows that this reflects bias and a lack of access, not a lack of ability in students from those underrepresented groups (National Research Council 2012). Systemic injustice is present in the teaching (Moss-Racusin…

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…

For most people, coffee roasting is a mysterious process. Chemically, it's equally mysterious; the roasting process gives rise to over 800 compounds. The science of coffee, from seed to bean to cup of aromatic brew, includes multiple areas of science content for students, and actively engages them in many science and engineering practices. Ask…

To enhance teaching and learning about Earth's climate and global climate change (GCC) in secondary science classrooms, the authors are engaged in a four-year, National Science Foundation (NSF)-funded project to develop, implement, and evaluate a new four-week curriculum module grounded in the use of a data-driven, computer-based climate modeling…

Wildland fires have become a regular aspect of life for people living in the western United States. Wildfire smoke is now impacting air quality across the United States. Unprecedented wildfires have swept through Australia, Russia, and Portugal in the last few years. Like other natural disasters, wildland fires can have a devastating impact on…

There is clear scientific evidence linking climate change to human activity. Despite this, we still find numerous public figures claiming there is no climate change, or that climate change data is "fake news." Societal polarization around climate change (Worland 2017; Pernett 2017; McCright and Dunlap 2011) can provide students with…

DNA extraction from strawberries is a well-known procedure that allows students to visualize DNA and to recognize that living things contain DNA (NHGRI 2018, Science Buddies 2013). In this article, the authors describe a modification to the traditional DNA extraction protocol that promotes student agency in experimental design and also emphasizes…
