Computational thinking (CT) is a thought process composed of computer science ideas and skills that can be applied to solve problems and better understand the world around us. With the increase in technology and computing, STEM disciplines are becoming interwoven with computing. In order to better prepare students for STEM careers, computational…

The topic 'Animals including humans' runs through the primary science National Curriculum in England (DfE, 2013). Ideally, topics such as inheritance will lead onto adaptation, natural selection and evolution across key stages 1 to 2 (ages 5-11). This article provides nine engaging activities to support the teaching of adaptation and improve…

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…

A lesson that focuses on the intricate co-evolution of flowers with their pollinators is one way to help students learn the delicate balance in nature and help ensure that our actions do not upset this balance. In this lesson students use the engineering design process to engineer a flower that is a perfect model for its chosen pollinator. Next,…

Understanding the nature of science has long been a focus of science education reform efforts, including the Next Generation of Science Standards. Students' views about the process of how scientific knowledge is acquired has been shown to affect their ability to learn scientific concepts. Integrating the nature of science into science lesson plans…

We describe a hands-on, collaborative activity designed to illustrate general properties of evolution, provide practice for quantitative skills, promote creativity and collaboration, and enable student self-assessment of learning. During the activity, teams construct bridges using common office supplies. The best-performing bridge becomes the…

In this classroom activity, students build a phylogeny for woody plant species based on the morphology of their twigs. Using any available twigs, students can practice the process of cladistics to test evolutionary hypotheses for real organisms. They identify homologous characters, determine polarity through outgroup comparison, and construct a…

Teachers are being challenged to engage students in ways that will elevate student interest and understanding of concepts in science and encourage students to gather evidence to support what we know about science. It is critical for teachers to have budget-friendly, supporting activities that are aligned with current educational standards, that…

The Eden Project, an educational charity based in Cornwall, is home to the largest rainforest in captivity and is a unique and awe-inspiring destination. It is one thing to talk about the idea of adaptation to environment but quite another to actually go into the rainforest and use your senses to explore up close living examples of ingenious plant…

The evolution of complexity remains one of the most challenging topics in biology to teach effectively. We present a novel laboratory activity, modeled on a recent experimental breakthrough, in which students experimentally evolve simple multicellularity using single-celled yeast ("Saccharomyces cerevisiae"). By simply selecting for…

In this activity, students examine nine hominin skulls for specialized features and take measurements that will enable them to determine the relatedness of these species. They will ultimately place each specimen on a basic phylogenetic tree that also reveals the geological time frame in which each species lived. On the basis of their data, and…

We describe an alternative to the kinds of observation-based lab exercises that are often used to cover animal and plant evolution with respect to transitioning from aquatic to terrestrial habitats. We wrote this activity to address these objectives, but also to model the process of scientific inquiry and to require students to collect and analyze…

Considerable anecdotal evidence indicates that some of the most difficult concepts that both high school and undergraduate elementary-education students struggle with are those surrounding evolutionary principles, especially speciation. It's no wonder that entry-level biology students are confused, when biologists have multiple definitions of…

This paper presents an activity that engages students in model-based reasoning, requiring them to predict the behavior of the trp and lac operons under different environmental conditions. Students are presented six scenarios for the "trp" operon and five for the "lac" operon. In most of the scenarios, specific mutations have…

For many students, preconceived notions about Darwin are among the most significant obstacles in learning about the theory of evolution by natural selection. I present an activity designed to eliminate this obstacle and encourage empathizing with Darwin, utilizing the history-of-science approach. Through the activity, students' negative thoughts…
