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…

This study aimed to determine the alternative frameworks of elementary school 6th grade students (aged 12-13) regarding the "flower" organ (alternative frameworks) and sources of these alternative frameworks. A total of 158 students from 3 public schools in the province of Bursa participated in the study. In this descriptive and…

Evolution and inheritance appear in the new National Science Curriculum for England, which comes into effect from September 2014. In the curriculum documents, it is expected that pupils in year 6 (ages 10-11) should be taught to: (1) recognise that living things have changed over time; (2) recognise that living things produce offspring of the same…

Children are naturally curious about the world in which they live. To focus this sense of wonder, have your students investigate their local habitat as it changes over the year. This multiseason study will build connections and add relevance to the habitats that children learn about. This series of activities for grades 4-6 explores the changing…

When it comes to directly interacting with and doing experiments with organisms, plants have some distinct advantages over animals. Their diversity and accessibility allows students to use them in experiments, thus practicing important science inquiry skills. This article describes an investigation that was designed to help students appreciate the…

An ethnographic study was conducted with the goal of evaluating the botanical concepts of sixth-grade students. One aspect of the study involved examination of the levels of abstraction students use for naming plants. Nine sixth-grade students were interviewed individually. Each was asked to identify the plants seen in a set of 64 slides and…

Describes the use of cross-age tutoring in which sixth-grade students are used to teach first-grade students about plants. Provides a list of praise words used by the sixth graders and discusses the mutual benefits received by the students. (MDH)

The assertion that there is a social component to children's construction of knowledge about natural phenomena is supported by evidence from an examination of children's classification schemes for plants. An ethnographic study was conducted with nine sixth grade children in central Texas. The children classified plants in the outdoors, in a…

An ethnographic study was conducted with the goal of comparing the botanical knowledge of nine sixth grade students with the botanical concepts developed in the elementary textbook series, Science, by Silver Burdett, 1985. The extent to which the child's conceptual framework resembles that of the scientist and the extent to which the textbook…

Through the 4-H Wheat Science project, students learn the importance of wheat from the complete process of growing wheat to the final product of bread. The curriculum is designed to include hands-on experiences in science, consumer education, nutrition, production economics, vocabulary, and applied mathematics. Teachers can select those units out…
