The variable I am going to investigate is the level of CO2‚ however‚ the addition of NaHCO3 (sodium bicarbonate) to the water may affect the osmotic ability of the water. Just 2g of sodium bicarbonate in 1000ml of water gives the equivalent salinity of seawater‚ and as Elodea is a fresh water plant‚ it cannot survive in salt water. I will need to take this into account when measuring the NaHCO3. To work out the rate of photosynthesis I am going to count how many bubbles of O2 are given off in

General Purpose: To inform Specific purpose: The audience will know that the Dead Sea is devoid of all plant and aquatic life‚ why the sea is so salty and the health benefits. Thesis or central idea: The Dead Sea has a unique environment Main Points: a. The Dead Sea is one of the saltiest bodies of water anywhere b. The Dead Sea is devoid of all plant and aquatic life c. The Dead Sea area has become a major center for health research and treatment Introduction: You know why

Soil Salinity Salinity in both the rivers and on the land is one of the main and most costly results of overclearing and irrigation. Salinity is caused by changes in the delicate balance between surface water and groundwater systems. A small increase in the infiltration of water from the topsoil to the groundwater‚ due to rainfall or irrigation‚ can result in a dramatic rise in groundwater pressure and watertable levels. The trees of the open forests are now replaced by shallow-rooted crops and

The Death of Abdulla the Camel Driver Introduction: Before we explore the conditions surrounding Abdulla’s death‚ let’s review some basic facts. We define diffusion as movement of materials from a region of higher concentration to a region of lower concentration. This movement is due to kinetic energy of particles. An example of this can be observed by opening a bottle of perfume. Soon you will smell the perfume in distant parts of the room. It diffuses from the high concentration

Salinity Experiment Aim To determine a method of measuring a soil sample’s salinity level in order to measure 3 samples’ salinity level. Hypothesis I think that by running a current through a salt solution and measuring the resultant amperage‚ a pattern in the recordings will help find a soil sample’s salinity level. Variables Controlled Amount of solution (100 mL)‚ supplied voltage (4V)‚ amount of soil (50 gm) & water (150 mL) in soil sample’s solution. Independent Amps recorded

INTRODUCTION: The research topic is based upon the impact of the abiotic factors on community properties in the aquatic ecosystems of bith La Vega and Caroni Swamp. The abiotic factors to be included ate salinity‚ turbidity‚ dissolved oxygen‚ phosphates‚ nitrates‚ pH‚ and temperature. Aqautic abiotic factors have become a prudent issue in these ecosystems affecting the abundance and distribution of species as well as feeding relationships as seen in food webs and food chains. In order to try to solve
