The Wiggers diagram showing simultaneous events of the cardiac cycle in composite graphs is one of the most intimidating figures students encounter in their study of physiology. This paper describes a discovery learning activity that walks students through the construction of the Wiggers diagram by focusing on the core concepts of blood flow down…

An increased public knowledge of the health benefits of unsaturated fats has resulted in a surge of different cooking oils. Intense advertising of various oil brands claiming to provide the best dietary recommendations often leaves buyers unclear of what their best choices are. Herein, we describe a research-based project for upper-level…

Our youngest learners thrive when their learning environment is one that celebrates curiosity, exploration, and imagination. This comprehensive resource sets the stage for play-based learning that will help children build a strong literacy foundation as well as negotiate the choices they make in real life. Get your students off on the right foot…

In this article, the authors share discoveries about how taking risks can expand students' and teachers' narrow experiences with academic writing. The article outlines four teaching strategies one of the authors implemented in her classroom, highlighting how these strategies fostered student and teacher flexibility, agency, and confidence in…

A discovery-based undergraduate organic chemistry lab experiment has been developed in which students establish the diastereoselectivity of hydride reduction of the a-chiral ketone (±)-benzoin isopropyl ether to erythro and threo diastereomeric alcohols by two different reducing agents. Students achieve this goal by working collaboratively and…

The so-called Diet Coke and Mentos experiment is initiated by dropping Mentos candies into a bottle of Diet Coke or other carbonated beverage. This causes the beverage to rapidly degas, causing foam to stream out of the bottle. Simple application of the gas laws leads to the straightforward prediction that ejection of greater foam volume is…

The ACS Guidelines for bachelor's degrees in chemistry call for the curriculum to include polymer chemistry principles and the synthesis of different classes of macromolecules. Organic chemistry can provide an important introduction to polymer chemistry principles, and photochemically induced radical polymerization is one method for generating…

Students thrive when presented with tasks that are approachable, challenging, and interesting. Remembering to challenge all students is essential, not just those who excel in mathematics; teachers need to open the door to meaningful mathematics for every learner. In this exploration into subtraction patterns, teachers will see how curious young…

Museums are public resources that can offer rich extensions to classroom educational experiences, from tours through botanical gardens to searching for family records in the archives of a local historical society. With clarity and a touch of humor, Quinn presents ideas and examples of ways that teachers can use museums to support student…

At first glance, science and art seem as likely companions as oil and water. Is there more to mixing them up than mere metaphor and a messy floor? In this article, Tom Pringle shares some ideas for powering up the classroom by turning STEM into STEAM by dipping the paintbrush of art into the pot of science. In both art and science pupils can…

One challenge of teaching chemical analysis is the proliferation of sophisticated, but often impenetrable, instrumentation in the modern laboratory. Complex instruments, and the software that runs them, distance students from the physical and chemical processes that generate the analytical signal. A solution to this challenge is the introduction…

Discovery sessions are usually based around a stimulus that the teacher has set up. When children are all doing something similar, watching what happens, talking about the science that is going on, the teacher has a way in to learn about their understanding, but then the teacher can take it deeper into exploring their skills in working…

This article describes how a farm-based class in the Great Lakes region investigated how plants and animals prepare for winter. Two groups of children, ranging in ages from three to five years old, had a farm, pasture, gardens, forest, and a pond available for exploration. A low teacher-to-child ratio was maintained, with one teacher to…

The outdoors can offer children a rich space for learning and inspires authentic mathematical opportunities. The author describes the experiences her kindergarten students have when when they spend many hours each day, exploring their vast play yard and engaging in play-based activities typically done inside a classroom. She also chronicles the…

Earth's easily seen surface features (mountains, volcanoes, and islands)--and the movement of the tectonic plates that lie below--offer hints about the processes that produced them. Inquiries in seismology, the study of earthquakes and other ground movements, can help students learn about Earth's geologic processes. This article describes an…
