Does Height Affect The Density Of A Human Experiment

Purpose: Weighing objects. Figuring out the density with an object by calculated volume and Archimedes’ Principle.

I will be doing this experiment to understand density of water compared to the volume of an object. D=m/v=mass/volume

It is hypothesized that the different heights of the test subjects will affect their lung capacity. This is because taller people have larger lungs, therefore allowing their oxygen intake to be greater than those of shorter people.

·  Compare the measurements in the study with the standard normal distribution, what does this tell you about the data?

2. This experiment is not able to support Matthew's hypothesis. Suggest specific improvements that will allow the experiment to more effectively test the given hypothesis. Explain why these changes are improvements.

In Measuring and Understanding Density, several experiments were performed to find density of regularly shaped objects, irregularly shaped objects, liquids and gasses. An additional experiment was done to find the specific gravity of a sampling of liquids. The purpose of the experiment was to provide a better understanding of density and to be able to extrapolate unknowns based upon these calculations. The experiments yielded data in keeping with Kinetic-molecular theory in regards to the density of water versus its temperature. Key measurements and formulae were also used to determine densities of metal and plastic objects as well as irregularly shaped rocks. It is possible to find the density of an object (be it liquid, gas or

1. Describe the context (why it was done, the general interest and what the researchers wanted to find out) of the research and research question (what is the hypothesis). /10

Conclusion: From what you observed, how would you answer your original question? Does the experiment support the hypothesis? Again, no personal

1. Using the data in the file named Ch. 11 Data Set 2, test the research hypothesis at the .05 level of significance that boys raise their hands in class more often than girls. Do this practice problem by hand using a calculator. What is your conclusion regarding the research hypothesis? Remember to first decide whether this is a one- or two-tailed test.

Our experiment was performed in the Science and Technology build on the USCB Bluffton Campus on October 6th from 4:30 to 5:30 p.m. In order to construct the study for this experiment, we divided the actual experiment work in order to be able to complete the study for all sixteen (16) subjects within the given time period available to accommodate the test subjects. The experiments was conducted in the hallway, during the process we tested three participants at a time. We constructed an informational form regarding gender, age, weight amount of exercise per week. The supplies needed were approximately 25 test participants for the class, informational form, a blood pressure reader, timer, 15 jumping jacks, three chairs, paper and pencil to record

The main purpose of the Density Lab is to be able to measure density of different objects whether it is a liquid or a solid. Density is the measure of how much mass in a specific matter. To find the density of a liquid you must find the volume and mass of the liquid. Density and specific gravity go hand in hand by that specific gravity is the density of substance/ density of stand, in this case and most cases the standard is water. You have to use the correct number threw out the calculations to get a scientifically accurate answer.

The purpose of the Density/Graphing Mini Lab was to determine how the density of a small amount of a substance relates to the density of a large amount of the same substance. The density of a substance is determined by the mass (resistance to change in acceleration) and the volume (how much space it takes up). To calculate density the formula used is, F = m/v. Mass is measured in g, volume is measured in mL, and density is measured in cm³. The hypothesis, “If the density of a small amount of a substance is compared to the density of a large amount of the same substance then they densities will be the same because the ratio between mass and volume remains the same,” was proven true as when mass is increased, volume increased as well at the same

If anyone else would like to carry out this experiment in the future, I recommend doing it on a surface that you don't mind getting dirty, as this eperiment was very messy. Mostly because I accidently spilled things. This experiment can be applicable to real life as density is very important in some scientific jobs like chemist or astrologist because density is a very important in those

The hypothesis is that two people of different sizes will have a different temperatures after preforming an activity, this was proven after collecting data from the experiment. The first thing that was noticed in this experiment was the difference in Darryl and Faith's thermal mass temperatures. When looking at the data chart Darryl’s core body temperature was a few degrees higher than Faith’s. The temperatures were taken by using a surface thermometer stick. After the exercises were completed it was shown that after one of the exercises Faith's thermal mass was higher than Darryl's. The exercises that Faith's thermal mass exceled in was when her and Darryl were running up and down the stairs. When running up and down the stairs at different

The overall purpose of the lab is to have the students practice designing an experiment, gathering data, and then analyzing that data to form a conclusion using the scientific method. It also served to understand key terms such as hypothesis, dependent variable, and independent variable. The specific objective of this lab is to determine whether certain human body parts experience allometric or isometric growth. Allometric growth defines when certain parts of an organism grow at unequal rates in comparison to its whole, while isometric growth is when all parts of an organism grow at the same rate in comparison to the entire organism. The specific purpose of the lab is to determine whether or not specific human body parts experience allometric or isometric growth by comparing the ratios of height to two specific body parts, in the students’ case the right hand length and head circumference, in students and newborns. The students formulated the tentative answer that if a team of four compared their height to right hand length ratio, as well as, their height to head circumference ratio, to those of a newborn’s, then the students will discover that the right hand and head experience allometric growth in humans.
