Measuring the Effect of Density on Growth of Mung Bean (Vigna radiata) Plants Wylliam Wagoner1 1 Population and Community Ecology‚ Butler University‚ Indianapolis‚ Indiana 46208‚ USA ABSTRACT For this experiment‚ we set out to find if density and time had an effect on growth of mung bean plants. We decided to test evidence of growth by measuring plant biomass. We measured the biomass each week for four weeks of plants grown at different densities. We found that density had an overall effect

Introduction: Specific gravity or relative density is the ratio of the density of a substance to the density of a given reference material. Specific gravity usually means relative density with respect to water. Temperature and pressure must be specified for both the sample and the reference. The following formula is used- Specific gravity= density of sample/density of same volume of water. Specific gravity is commonly used as a simple means of obtaining information about the concentration of solutions

me how to convert between SI units and standard American units of mass‚ length‚ temperature‚ volume and time as well as how to measure the units. Students become proficient in laboratory techniques such as measuring temperature and volume and calculating within them. Procedure: I used a measuring device such as a ruler‚ balance or volumetric flask to determine the values for each measurement. DATA Tables: Data Table 1: Length measurements.

4/3/14 Period 5 Review 5.1 1. The difference between measuring mass and measuring matter is weight is measured in pounds while mass is measured in grams. 2. The mass of the package would be 2 kilograms. 3. The mass of the package would stay the same. 4. The volume of this object would be 80cm3. 5. The volume of the object would be 22mL and 22cm3 6. Density relates to volume and mass. 7. The density of this object would be 5g/cm3 8. The density of a material will always be the same because it’s

Background examination for the Dominant Thumb Experiment: • Upon reading the literature that the researcher found by googling‚ "Thumb Dominance‚" they discovered that almost every human being has a dominant thumb whether it be the right thumb or the left thumb on top after naturally clasping their hands together. However‚ if the individual tries to force their clasped hands to let the other thumb become dominant it ’s most often described as feeling awkward or abnormal. In 1999‚ a scientist by the

methods‚ thermal expansion‚ density‚ and specific heat were used to identify two small metal rods. The overall purpose of this experiment was to identify an unknown metal using the three previously stated properties. This means that the percent error should be relatively low‚ meaning that there would be little difference between the values measured in our experiment and the true values of the metal. Density was the simplest experiment. It basically entailed measuring the length and diameters of

Meter enables a high precise fuel consumption measurement also at low flow rates and short measurement times. With a high accuracy mass flow sensor the fuel consumption is determined continuously and via direct mass flow measurement in kg/h. The density does not have to be determined in addition to the direct determination of the gravimetric or specific fuel consumption like in volumetric measurement methods. The fuel consumption can thus be determined to an accuracy of 0.12% for the whole system
