Ryperian Buffer Lab-
Use topographic maps and google earth to plot out stream buffers and how they have depleted throughout time. Students will compare maps from 1960's to present google earth info to see how the stream buffer zones have depleted.
Teachers feel this lesson reaches Bloom's first five levels, and could reach the evaluation level if they evaluate the root causes of depletion and the negative and positive effects of this. Do they feel that the depeltion of the buffer zones can be justified with economic development, etc.
Teacher direction comes in materials and basic instruction, student direction comes from determining what counts as buffer on the maps, and choice of streams. Motifications can come in the form of brainstorming and developing causes and solutions to this problem, and possibly plan new development that will promote conservation.

General Sciences

Coral Tank
Take fragments of living coral tissue and propogate it by changing the levels of light, temperature, ph levels, water movement, etc. Measure progress over the course of months and show how the effects of polutants and changes in environment can effect the growth/development of the coral.
You can then show how to change the ph levels by both adding CO2 which would create the acidic ph level or how one can change the level of ph in the water by adding more organic material and the conditions of its development.

Sonar Lab
Give students speed of sound in water, and then give them a scan of sonar time as you cross the susquehanna river. So kids use the timing to graph the bottom of the river. Students can then use these numbers to find treasure in the bottom of the river. Integrating math and science.
