Ecosystems, interacting systems of biotic and abiotic factors, are a fascinating topic in life science. The "Next Generation Science Standards" (NGSS Lead States 2013) recognize "Ecosystems: Interactions, Energy, and Dynamics" (HS-LS2) as one of four overarching ideas in life science that students should understand. Student…

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…

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…

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…

Science is full of amazing facts, but at times it may be difficult to fully appreciate their significance without an understanding of the scientific practices that gave them meaning. The teaching of evolution may be an example of this situation; there are many interesting facts to consider, but it is equally important for students to learn where…

The primary learning objectives of this "Next Generation Science Standards" (NGSS; NGSS Lead States 2013) aligned activity is to help high school biology students experience firsthand the role of replication in scientific inquiry and food preference as a behavioral reproductive trait of the Madagascar hissing cockroach. The secondary…

This paper highlights learning supports associated with genetics lessons that were implemented in a urban high school biology classroom. The supports provided access to science content for ELLs [English language learners], students with IEPs [individualized education programs], and struggling readers during an introductory unit on genetics. Due to…

Interactive science simulations (sims) have become popular tools for science educators, and research confirms that sims can improve student learning (Rutten, van Joolingen, and van der Veen 2012). Over the past 15 years, the PhET Interactive Simulations project at the University of Colorado Boulder has created a collection of 150 open (free)…

The unequal distribution of natural resources is the direct result of past geologic processes. Once a promising region is located, geologists use a variety of techniques to find the materials and energy that society consumes. Their tools can be as simple as a hand lens or as sophisticated as a satellite. Along the way, exploration geologists and…

Most likely a large number of students have heard of the Northern Lights (Aurora Borealis), and know that they are a phenomenon in the sky. Although they may not have seen the Northern Lights, most have probably seen other phenomena in the sky, such as a rainbow, shooting star, or super moon. These experiences provide an opportunity for students…

This high school life science unit introduces students to the intersection of science, economics, geography, and culture through the current practices of palm oil cultivation in the tropics. For this article, the authors travelled to Sabah Province, Malaysia, to visit palm oil plantations, conduct interviews, and collect resources to help students…
