Lab #5: Dissolved Oxygen Lab Be sure to read and understand the below instructions BEFORE the lab! Experiment 1: Investigating the Effect of Temperature and Salinity on the Concentration of Dissolved Oxygen in Water Introduction: In an aquatic environment‚ oxygen must be in a solution in a free state (O2) before it is available for use by organisms (bio-available). Its concentration and distribution in the aquatic environment are directly dependent on chemical and physical factors and are

Subject Content Most of the objectives specified in this section relate to Knowledge with Understanding‚ although some indication has been given as to where the skills of Handling Information and Solving Problems may be developed. Teachers are reminded that‚ in the written papers‚ 40% of the marks are allocated to these higher ’thinking’ skills. In almost every section‚ students should therefore be given practice at dealing with unfamiliar situations so that these higher thinking skills can be developed

STATE HIGH SCHOOL | Comparison of fertilizers on plant growth | | | Year 11 Biology Year 11 Biology Abstract An investigation was carried out to compare the effect between inorganic and organic fertilizers on plant growth. Tomato seedlings were used‚ which were divided into 3 groups - the inorganic fertilizer group‚ the organic fertilizer group and the control group. Besides using different fertilizers‚ all of the seedlings were planted in the same condition. The result has shown that

The coral reef structure also buffers shorelines against waves‚ storms‚ and floods‚ helping to prevent loss of life‚ property damage‚ and erosion. Several million people live in U.S. coastal areas adjacent to or near coral reefs‚ and the well-being of their communities and economies is directly dependent on the health of nearby coral reefs. Reefs also protect the highly productive mangrove fisheries and wetlands along the coast‚ as well as ports and harbors and the economies they support. Globally
