Investigation of the rate of photosynthesis of pondweed. Research question: How does the concentration of sodium bicarbonate relate to the amount of oxygen produced by Elodea (Canadian pond weed) in the process of photosynthesis? Hypothesis: If there is an increase in concentration of sodium bicarbonate the amount of oxygen produced will increase because the sodium bicarbonate concentration will increase the carbon dioxide levels. Independent variable- Concentrations of sodium bicarbonate (8%

for instance Price Earnings Ratio (P/E) and Price Book Value Ratio (P/BV).

Since JetBlue does not pay out dividend before listed (despite dividend distributed to preferred shares shareholders)‚ such model is considered as inapplicable. The FCFE and FCFF method were developed for firms which does not distribute dividend and their valuation is

wasn’t any flaws in this experiment. When changing this experiment use different brands‚ scents or waxes and see which one would burns faster. The results were the unscented candle burned faster but they both burned at the same speed rate so it doesn’t really matter too much. Other brands could change the effect of the burn rate than other brands that are out there and they may also be made differently. There are more than one wax and that might change the burn rate of the candles. Some waxes may last

Introductory Activity Heart Rate (pulse) Have the students find their heart pulse on the carotid artery of the neck. Use the index and middle finger to measure the pulse. Count the number of beats for 6 seconds and add a zero to the end of that number. This number represents the heart beats per minute. The heart pulse is located on either side of the wind pipe‚ next to the voice box. Allow the students to practice measuring their pulse to determine their resting heart rate. Explain that they need to
