Describes an elementary school teacher's implementation of authentic assessment strategies, in her science class. Discusses her use of different strategies including science logs, performance assessment, creative drama, scrapbooks, and interviews. Highlights factors that contributed to successful implementation of assessment strategies,…

Describes a project in which discussions were held between agriculturalists and elementary teachers in order to provide an opportunity for the participants to examine the ways in which science is developed and used in an occupational context integral to the community. Examines the views of science and school science expressed by the participants.…

Uses charcoal briquettes, ammonia, water, table salt, and laundry bluing to create white fluffy crystals. Briquettes are placed in a bowl while the remaining ingredients are mixed together and poured over the briquettes. The result is white fluffy crystals forming on top of the charcoal. This experiment dramatizes chemical reactions to…

Children love observing seeds change as they germinate and grow into tall healthy plants, but how can teachers make investigating plants an exciting and immediate event? Microscopy might just be the answer. Although most students have seen flowers, not many have looked closely at their various structures or seen their colorful designs only…

Spring is an exciting time in any kindergarten classroom. The children are communicating better, and they have begun working more independently. Their critical-thinking skills are growing each day. Last year, as the warm days of spring teased our senses, a plant unit seemed especially enticing, so the author created four interactive, plant-themed…

The author is surprised every year when fifth-grade students react to the study of biomes as if they've never given any thought to the differences across parts of the world. Sure, they've all heard of the tropical rain forest and the desert, but it seems as though they think the rest of the world is just some undefined area with climate, animals,…

The science notebook is more than a record of data that students collect, facts students learn, and procedures students conduct. It is also a record of students' questions, predictions, claims linked to evidence, conclusions, and reflections--all structured by an investigation leading to an understanding of "big ideas" (not factoids) in science. A…

Thematic topics offer tremendous potential for science learning in the early grades and beyond. One second-grade class explored honeybees, a subject their teacher found both fascinating and easy to connect to a number of learning standards and science concepts. Her unit, "Honeybees and Apple Trees: A Close Look at Nature's Balancing Act," explored…

This elementary activity follows the 5-E Learning Cycle as described by Bybee et al. (1989) and integrates literature from Dr. Seuss. Students observe and identify characteristics of several slime substances and must make comparisons to determine which one most closely resembles the slime substance described by Dr. Seuss. To maximize this…

Land snails are common invertebrates that fascinate children. Unfortunately, they are seldom used for activities in the science classroom. Snails are inexpensive, take up little space in the classroom, and require only low maintenance, and their learning dividends can be enormous. For example, students can use them in inquiry-based activities that…

Renewable energy is harnessed from natural and sustainable sources, like wind, sun and water. They offer a pollution-free, endless source of electricity that is crucial in the fight against climate change. Every unit of this "green" electricity directly replaces electricity normally generated from conventional polluting sources such as coal or…

Most primary science practitioners would immediately list questioning as one of the key ways in which they influence children's learning. Even so, effective questioning is not a straightforward skill. In this article, the author offers ideas to help practitioners understand the relevance and importance of questioning in primary science and how…

When thinking about talk and discussion in primary science, the author often returns to the little gem of a book by Douglas Barnes--"From communication to curriculum" (1976). Barnes used observations of science lessons to make cogent points about the value of talk for both thinking and communication. A useful distinction that he…

Pupils' books in primary science are either rarely used, underused, or misused, even though many excellent books and schemes exist. Various explanations have been offered, such as cost, lack of "match" to the QCA scheme, failure to differentiate, lack of visual literacy, cultural inappropriateness, and language problems (Peacock, 1995, 1997). So…

Why introduce genetics at primary level? Children are fascinated by themselves and where they come from. Many have heard of genes, mostly through the media coverage of genetics, and want to know more. Children should be engaged in science at an early age to foster an interest and encourage an appreciation of its relevance to life. Genetics sits…
