Germinating a seed is presumably the first experiment made by a child in his life. So, it has an important place both in child's scientific experience and understanding. Despite the significance of the experiment, the literature indicates that students possess various misconceptions related to the concepts of seed and seed germination. So, it is…

Plants encounter several different threats that affect their well-being during the spring. With chemistry, plants may defend themselves from, for example, excess UV-radiation and herbivores. The defense compounds between plant species vary, which makes it possible to utilize chemistry in identifying the plant species. In this laboratory…

One of the most captivating things about plants is the way they capture the Sun's energy, but this can be a difficult topic to cover with elementary students. Therefore, to help students to make a concrete connection to this abstract concept, this series of solar-energy lessons focuses on leaves and how they act as "solar collectors." As students…

Presents an interview protocol used to identify and evaluate students' conceptions of plants which is an invitation to participate in the third national study exploring elementary students' science conceptions. (YDS)

This document contains a set of instructional materials about photosynthesis that were used in a research study of middle school science teaching during 1985-86. The Middle School Science Project investigated ways to help middle school science teachers use teaching strategies that were identified in earlier studies as particularly effective in…
