Earth Sciences/ Planetary Sciences/ Physical Environments
Objectives/Goals The objective of this experiment was to find the effects of turbidity on dissolved oxygen levels in various water samples. Methods/Materials Seven water samples were collect…

Earth Sciences/ Planetary Sciences/ Physical Environments
Objectives/Goals The objective was to determine whether fresh water holds heat longer than salt water. I think that the salt water will hold heat longer than fresh water because salt water h…

Earth Sciences/ Planetary Sciences/ Physical Environments
Objectives/Goals Since California is unprepared for a major tsunami, I wondered if a man made shallow underwater structure would make the wave break earlier before and give up some of its de…
CSEF · 2006
Earth Sciences/ Planetary Sciences/ Physical Environments
Objectives/Goals Building foundations are usually made of steel and concrete, which in turn rely on a solid soil base beneath them for stability. During an earthquake the soil base undergoes…
CSEF · 2006
Earth Sciences/ Planetary Sciences/ Physical Environments
Objectives/Goals The objective is to find out what location (front, middle, back) and length of seepage curtains cause the most resistance to seepage under dams. If dams with seepage curtain…
CSEF · 2006
Earth Sciences/ Planetary Sciences/ Physical Environments
Objectives/Goals The objective was to determine the affect bottom contour has on the height of a wave. I wanted to try to reduce a wave as much as possible. I wanted to find a possible way t…
CSEF · 2006
Earth Sciences/ Planetary Sciences/ Physical Environments
Objectives/Goals to measure the dissolved oxygen in different water sources and some different areas of the rivers to see if it effects the aquatic life. Methods/Materials La motts dissolve…
CSEF · 2006
Earth Sciences/ Planetary Sciences/ Physical Environments
Objectives/Goals To find out which mineral causes the biggest sinkhole when mixed with water. Methods/Materials For my experiment, I covered the bottom of a container with six inches of sand…
CSEF · 2006
Earth Sciences/ Planetary Sciences/ Physical Environments
Objectives/Goals To examine which soil textures can hold the most water (water holding capacity). To check that different soil textures have different water holding capacities. Methods/Mater…
