Effect of Osmosis on Egg Introduction: The purpose of this lab was to test the effects of hypertonic‚ isotonic‚ and hypotonic environments on the weight of a shell-less egg. We tested the weight of the egg after thirty minutes in water as well as corn syrup. I hypothesized that when the egg was placed in water‚ it would swell and gain weight because it was in a hypotonic environment. That hypothesis was correct as the egg grew slightly and the weight when up. I also hypothesised that when the egg

Victor Seo has developed an experiment to prove the hypothesis: “people who consume lots of chocolate will produce more acne than people eat less chocolate. 400 students of teenagers with grades ranging from 9 to 11 will be examined divided into four groups each consuming 1 bar‚ 3 bars‚ 6 bars‚ or 10 bars daily. This experiment will remain over a time period of a month. Meals will be served in equal amounts and the amounts of acne will be recorded every week. METHOD In secondary schools in Toronto

Reverse Osmosis For Wastewater Recycling Reusing treated wastewater for beneficial purposes‚ such as agricultural and landscape irrigation‚ industrial processes‚ toilet flushing‚ or groundwater basin replenishment‚ is growing in response to environmental and economic concerns. One of the key factors involved in recycling wastewater treatment plant (WWTP) effluent for another use is the need to reduce total dissolved solids (TDS). This is often done by using a reverse osmosis (RO) system‚ which

Sometimes the data we need may not be available from internal or external sources. In such cases‚ we may have to obtain data by conducting our own survey or experiment. In a survey‚ we do not exercise any control over the factors when we collect information. For example‚ if we want to collect data on the money various families spent last month on clothes‚ we will ask each of the families included in the survey how much it spent last month on clothes. Then we will record this information. A survey

Biotechnology‚ Mapua Institute of Technology ABSTRACT In this experiment‚ solubility class of various organic compounds are to be determined. The main objective of the experiment is to identify an unknown compound through the use of preliminary tests such as examination of physical state‚ color‚ odor‚ and ignition properties. Also‚ solubility tests were used to further examine an unknown compound’s solubility class. In this experiment‚ the apparatus used are micro test tubes and droppers for mixing

Title Antimicrobial properties in different type of plants. Introduction A substance that kills or prevents the growth of microorganisms for example bacteria‚ fungi or protozoans is called an antimicrobial. This substance has 2 major roles which are to either kill microbes (microbiocidal) or prevent the growth of microbes (microbiostatic). Disinfectants are antimicrobial substances used on non-living objects outside the body. This substance included antibiotics‚ antifungals‚ antiprotozoals and

The graph should show an increase in arbitrary units the further away from the light source the beaker is because the greater the distance from the light source‚ the lower the light intensity and so less photosynthesis
