Presents four elementary hands-on science activities that highlight animal adaptation (how birds' beaks are adapted to suit their habitats), the water cycle (how nature cleans rainwater that seeps into the ground), aquatic ecosystems (changes over time in an aquatic habitat), and animal habitats (all living beings' need for food, water, shelter,…

Describes the planning and implementation of a science week intended to raise the awareness of science in an elementary school. Educational requirements included exciting science happenings and concentrated science teaching of a high standard. The week included demonstrations, guest speakers, and schoolwide assemblies. Demonstrations included the…

In this paper, we take up and advance the project of rethinking "scientific literacy" by Eisenhart, Finkel, and Marion (American Educational Research Journal, 1996, 33, 261-295). As part of a project of rethinking science education, we advance three propositions. First, because society is built on division of labor, not everybody needs to know the…

A lot of good elementary science involves studying solids, liquids, and gases, and some inquiry-based activities that are easy to set up and do. In this article, the author presents activities pertaining to simple phase change. Using water as the example, these activities introduce upper-grade students to the idea of the arrangement of molecules…

The sight of young children eagerly reaching for and eating string beans, carrots, lettuce, radishes, and even raw beets and onions is an incredibly satisfying one for a science teacher. The experience of growing food is a natural motivation for getting children to eat more healthful foods, and the process of how food is grown, harvested, and…

While babysitting or preparing home meals, young people (and adults too) sometimes overlook cleanliness procedures. One of the first employment opportunities for teenagers is often in a fast-food restaurant where the safe handling and proper cooking of foods is essential. To teach students about food safety practices, the U.S. Food and Drug…

The concept of waves is fundamental due to its occurrence throughout the natural world. Because the concept occurs in so many places, students come to the classroom with prior knowledge, as well as misconceptions, about waves. Students have misconceptions about what is waving in a wave, what properties of the medium determine wave speed, and how…

This article discusses how children can build teamwork through science activities. Through science experiences, the excitement can generate a sense of shared community in class. Science experiments help develop children's learning. Science experiences are a prime source of powerful new words because they use a common language to describe the…

This article describes a lesson in which students construct Bohr's planetary model of the atom. Niels Bohr's atomic model provides a framework for discussing with middle and high school students the historical development of our understanding of the structure of the atom. The model constructed in this activity will enable students to visualize the…

The topic of wetlands provides a rich context for curriculum integration. This unit contains seven activities that integrate environmental science with math, technology, social studies, language arts, and other disciplines. In this series, students will identify plants and animals found in wetlands, understand the function of wetlands through the…

A partnership between a university and a science and technology magnet school brings a renowned herpetologist. Dr. Meg Stewart, to involve third-graders in her studies of coqui frogs. These students prepared to meet this scientist with a series of lesson plans (eight activities and four lab lessons) to learn the anatomy, behavior, and diversity of…

Observing young children learning is an indispensable part of teaching in the early years and this is clearly acknowledged in the "Curriculum guidance for the foundation stage." It is through observing and assessing learning that one can find out what children know and what skills and concepts they appear to have acquired. In this…

This study compares two methods of instruction in practical school biology. The content remains the same but two teaching methods are used, one based on workstations (Group 1) and the other a conventional approach (Group 2). The content was a regular 9th grade syllabus issue: visual perception. Method 1 included a phenomenological introduction,…

This article is about the relation between case-based learning and transfer in teacher education. Through a design research approach a multimedia case has been developed. The topic of the case is "outdoor activities in science education." The core of the case is a 17 minute video that is supplemented by all kinds of background information. Results…

Introduction: This research addresses preschoolers' intuitive understanding of rectilinear movement and some variables which affect it, and the type of arguments used when related knowledge states are justified. A first working hypothesis is that the resolution of practical, functional situations would be based on self-regulation processes. A…
