This study investigated students' meaning-making of polymeric concepts during modelling and discuss students' creation of visible representations in chemistry. The analysis combines a phenomenographic and social semiotic approach and leads to the finding and description of 21 different meaning-making processes. We refer to meaning-making as the…

Harmful plastic debris found on beaches and in the oceans are not limited to drinking straws or bags. There are several synthetic organic polymers that can be used to make different kinds of plastic materials and have resulted in billions of tons of waste that can reach the aquatic biome and are harmful to freshwater and marine communities as well…

Plants and plant products are key to the survival of life on earth. Despite this fact, the significance of plant biochemistry is often underrepresented in science curricula. We designed an innovative laboratory activity to engage students in learning about the biochemical properties of natural polymers produced by plants. The focus of the hands-on…

Background: Recently, there is a growing interest in independent learning approaches globally. This is, at least in part, due to an increased demand for so-called "21st century skills" and the potential of independent learning to improve student skills to better prepare them for the future. Purpose: This paper reports a study that…

"I Wonder" boards are a teaching strategy that can be used in the classroom, as well as during science learning opportunities in nonformal settings, such as after-school science programs or summer camps.This simple strategy has led to deeper science exploration in 4-H, as young people learn alongside program staff, teachers, or…

Environmental issues can serve as a marvelous framework for high-level student analysis of critical scientific and social concerns. We describe a series of activities and discussions that motivate students to explore environmentalism, sustainable development, carbon offsets, and related ideas with an engaged learning format that helps students to…

Many first year students of anatomy and physiology courses demonstrate an inability to self-regulate their learning. To help students increase their awareness of their own learning in a first year undergraduate anatomy course, we piloted an exercise that incorporated the processes of (1) active learning: drawing and plasticine modeling and (2)…

In this lesson, a ready-to-teach cooperative reading activity, students learn about the effects of plastics in our environment, specifically that certain petrochemicals act as artificial estrogens and impact hormonal activities. Much of the content in this lesson was synthesized from recent medical research about the impact of xenoestrogens and…

Littering is a careless act indicating lack of respect for the environment, other people, and wildlife. Through education people can learn the consequences of littering and how to stop doing it. This book, designed for elementary children, presents a collection of 16 activities, ideas and resources concerning litter in the aquatic and marine…

The materials in this curriculum supplement, developed for middle school or high school science classes, present solid waste problems related to plastics. The set of curriculum materials is divided into two units to be used together or independently. Unit I begins by comparing patterns in solid waste from 1960 to 1990 and introducing methods for…

The teacher developed curriculum guide provides the industrial education teacher with the objectives, equipment lists, material, supplies, references, and activities necessary to teach students of the 9th and/or 10th grade the concepts of interrelationships between material analysis and processing systems. Career information and sociological…
