    can reach a new pH level by interacting with soil. If water has a pH that is too high or too low‚ it can be life threatening to aquatic species and can corrode metal structures. After finding this out‚ I decided to test if water could reach an extreme pH just by interacting with soil around it. The question for this experiment therefore became the following. Will interaction with soil change the pH of water? I hypothesized that if water interacts with soil for three days‚ then the pH of the water will

    effect of three different pH levels (4‚ 7‚ 10) on the rate of germination of spanish beans Research Question: What is the effect of three different pH levels (4‚ 7‚ 10) on the rate of germination of spanish beans? Independent Variable: The different pH levels in the water would be the independent variable in this lab. Three different pH levels were tested‚ 4‚ 7 and 10‚ both 4 and 10 were chosen because they are 3 pH levels away from 7 which would be the regular pH level of water. We measured

    Abstract Scientific method is a systematic observation‚ measurement and experiment. It is the formulation and testing of a hypothesis. When analyzing pH it measures for the acidity or basicity of a solution. pH levels vary depending on the solution. The more acidic solutions would be juices and vinegar and cleaning materials would be basic. You can determine the purpose of solutions based on their acidity and basicity. We measure the pH of solutions on a scale with levels from 1-14. These levels

    WIRELESS VIBRATION MEASUREMENT SYSTEM Vibrations are caused due to mechanical oscillation of a structure about an equilibrium point. There will be vibrations involved everywhere where there is any rotating system‚ mechanical system is involved. The vibrations involved at in these places will of high frequency. There will some places where the vibrations of lo0w frequency will be present which will also disturb the normal operation of the system or faultiness in the values measured by the system
