Data collected in many biology laboratory classes are on ratio or interval scales where the size interval between adjacent units on the scale is constant, which is a critical requirement for analysis with parametric statistics such as t-tests or analysis of variance. In other cases, such as ratings of disease or behavior, data are collected on…

In this article the authors describe a model that starts from the basics of the OWL (observe, wonder, learn) large-group discussion strategy then moves onto new experiences that serve as the jumping off point for student-generated questions and investigations. The OWL version of a KWL (Know-Want to Know-Learn) process becomes a path to language…

Life would not be possible without plants. Plants supply food to many organisms (including people), produce oxygen, absorb carbon dioxide from the air, provide products for human use, and homes for many other living things. It is not surprising, therefore, that plant growth is a familiar topic in the primary school science curriculum. This paper…

DNA barcoding is an important molecular methodology for species identification that was developed over the last two decades and it should be covered in the biology bachelor curriculum. Here, we present an example of DNA barcoding by sequencing a segment of the 28S nuclear ribosomal large subunit rRNA gene of wild mushrooms and framing the…

Nitrogen- or phosphorus-based fertilizers, used in agriculture, can run off into nearby waterways during periods of heavy rain or high flow and cause harmful blooms (Paerl et al. 2016), low oxygen (Joyce 2000), and decreased biodiversity (Sebens 1994). Studies of the effects wetlands can have on water and habitat quality (Verhoeven and Meuleman…

Increasingly, undergraduate institutions are incorporating original research into the curriculum as a matter of best practice. However, while the practice of science has grown more collaborative, undergraduate research has remained largely confined to single-institution studies. Incorporating long-term, distributed research projects into the…

Civilization simply would not exist without plants, yet their importance is often overlooked. As the nation's ability to respond to the botanical challenges associated with food production, climate change, invasive species, and biodiversity loss continues to decrease (Kramer, Zorn- Arnold, and Havens 2010), educators must discourage this…

In this study, we explored how a teacher used a new mobile application that enables students to collect data inside and outside the classroom, and then use the data to create scientific explanations by using claim-evidence-reasoning framework. Previous technologies designed to support scientific explanations focused on how these programs improve…

A "citizen science" outreach program was aimed at high school students in Western Australia with a focus on agricultural sciences. The program had two main objectives: the collection of samples and the mapping of the distribution of the leaf disease powdery mildew of barley across the state; and support for the teaching and learning of…

This column presents ideas and techniques to enhance science teaching. In the "Talking Window Garden" project, students create "smart" plant pots that use sensors to collect and analyze data on the health of their plants. The Talking Window Garden project was a collaborative effort between an elementary teacher who wanted to…

The Next Generation Science Standards (NGSS) will define science education for the foreseeable future, yet many educators struggle to see the bridge between current practice and future practices. The inquiry-based methods used by Extension professionals (Kress, 2006) can serve as a guide for classroom educators. Described herein is a method of…

What if you could challenge your second graders to design an outdoor STEM classroom with a butterfly garden, birdbath, and sundial? With this volume in the "STEM Road Map Curriculum Series," you can! "Investigating Environmental Changes" outlines a journey that will steer your students toward authentic problem solving while…

Participatory research is a useful technique for collecting basic data over a large geographic area. Garlic production was chosen as a participatory research study focus in Maine. Project participants (285) received bulbs to plant, monitored their crop, and reported data online. Participants received a monthly educational newsletter to improve…

The progression of the taxonomic organization of life from Linnaeus's original two kingdoms to the traditional five-kingdom system to today's widely accepted three-domain system is explored in a group-learning activity. Working with a set of organisms, students organize them into each system. Discussion after each step focuses on viewing…

A Framework for K-12 Science Education (NRC 2012) includes inheritance as a core idea within the life science framework. For example, life science core idea 3A states that by the end of second grade, children's knowledge should include the ability to recognize and investigate physical differences and similarities among the same kind of…
