9 Summary

In this unit you have found out that:

  • The sensation of pain is caused by the release of a chemical (prostaglandin) that stimulates the nerve endings and sends an electrical message to the brain.

  • Pain can be reduced if the formation of prostaglandin can be inhibited.

Plant Structure
The plant stem is  above ground and supports the plant leaves. The stem is made of the protective dermal tissue, the ground tissue and the bundled  tissue. Plants have one primary root and secondary root branches that contain thousands of root hairs and this is explained in this three minute video. A word wall and/or handout would be most helpful in watching this video because the graphics are poor.

According to the promises: the subculture of school science, teachers' pedagogic identity and the ch
This paper reports findings from the Economic and Social Research Council-funded InterActive Education Project, in which teachers, researchers and teacher educators have worked together to develop, perform, and evaluate secondary school science department-based ‘Subject Design Initiatives’. Drawing on notions from sociocultural theory, we have focused on ‘cultural tools’ as material and symbolic mediators of learning. In the Subject Design Initiatives teachers are seen as central to lear

4.3 Dutch elm disease

Not all change is a direct result of human intervention. Sometimes changes can occur over which we have little control. One such example is the case of Dutch elm disease (so-called because most of the early studies of the disease were carried out in Holland, although the disease was first observed in France in 1918). The disease is caused by a fungus, Ceratocystis ulmi, that has the elm, Ulmus procera, as its only habitat and food source. Spores of the fungus are carried by the
