Essential Science for Teachers: Physical Science Session 3. Physical Changes and Conservation of Mat
What happens when sugar is dissolved in a glass of water or when a pot of water on the stove boils away? Do things ever really "disappear"? In everyday life, observations that things "disappear" or "appear" seem to contradict one of the fundamental laws of nature: matter can be neither created nor destroyed. In this session, participants learn how the principles of the particle model are consistent with conservation of matter.,In this segment the interviewer asks the student to draw and explain

2.3 Summary

In this unit we have used the Blackwater to identify the theme of environmental response. Responses involve the interaction of human and natural processes. For example, the rise in sea level experienced in the estuary is partly natural readjustment after the Ice Age and partly a response to greenhouse gas emissions caused by human activity. This rise has brought about two forms of response: human responses to change in the environment and responses made by the environment.

1.2.2 Change and response in the ‘meadows of the sea’

Midway along the northern shore of the Blackwater estuary lie the Old Hall Marshes on a peninsula three and a half miles long and lying between tidal creeks and mudflats (see Figures 3 and 15a). It is a wild, flat, remote area of mixed habitats of reedbed, open water, saltmarsh and improved and unimproved grassland. Ecologically, it constitutes coastal grazing marsh (Author(s): No creator set

1.2.1 Managing risk in conditions of uncertainty

Earlier we considered what is meant by ‘environmental responses’. There are two aspects to this concept. One is the response made by the environment to processes of change, whether brought about by natural or human causes or a combination of both. The other is the response to environmental changes made by humans or non-humans. In this section we shall consider both of these aspects of response by focusing on an issue of particular significance in the Blackwater: how the

1.1.2 A balancing act: conservation and sustainable development

All around this coast are examples of efortsf to protect or enhance the environment. There are nature reserves, country parks and protected habitats, and the whole coastal fringe is designated as an area of scientific interest requiring special protection. There is also evidence of the need to manage the environment to ensure, so far as possible, compatibility between competing interests. Built development is prevented along the shoreline and restricted to existing settlements; caravan parks
