Title:
Comparing the absorbency rate of different brands of diapers.
Introduction:
Many parents these days find it difficult to make the right choice on different brands of diapers. The choices may seem endless when searching for a disposable diaper. They select the diapers after seeing the advertisements. Once they start using the diapers they will be facing problems like, wetting, rashes and burns in babies.
A disposable diaper is generally composed of an inner layer of polyester that allows liquids to pass through to a layer of absorbent material, and an outer waterproof plastic layer of polyethene film. A disposable diaper's absorbent core contains wood pulp (usually bleached white with chlorine) and super-absorbent polymers, usually sodium polyacrylate (a

A good quality diapers should be able to absorb a good quantity of urine in it. There are two main reasons for the leakage of diapers. The biggest cause of diaper leakage is an inadequate diaper material or the poor absorbency of the diaper. The second reason is the size of the diaper. Parent should select adequate size of diaper for their baby because different brands will have different sizes for a specific weight range. Also the thickness of the diaper material differs for various brands. Therefore I have decided to do a research on various brands of diapers to test their rate of absorption.
Research Question: To determine the absorbency rate of some branded disposable diapers.
Independent Variable:
The five different brands of diapers
Dependent Variable:
The amount of water absorbed by the diaper
Variable Controlled Way the variable is to be controlled
Initial amount of water 500 ml
Size of diaper 10cmx10cm
Absorption time 5 minutes
Materials:
➢ 15 Different diapers (5 different brands with 3 of each brand)
➢ Stopwatch (1/100 sec)
➢ Measuring cylinder
What were the variables? The independent variables are the male and female gender. The dependent variable are the dosage of bolus given. 1.
Identify the independent Variable Size of the tablet Identify the dependent Variable Reaction time List the controlled variables The solution (water), temperature, volume of water (200 mls) The amount of Alka- Seltzer How will the dependent variables be measured A stop watch will be started as the pieces of Alka-Seltzer are dropped into 200ml of room temperture water Describe the expected results if the hypothesis is true The 3 smaller pieces of Alka Seltzer will dissolve quicker than the ½ tablet .
a biology class wants to perform an experiment to investigate the effect of different colors of light of green, yellow, red and clear cellophane and plant three seeds in each one. What part do the three seeds experiment? A,Confounding variables B.Independent variables C.Control variables D.Dependent variables 40. Iodine directly helps which of the following glands to function properly?
Executive Summary: There were three brands of garbage bag rolls: Limp-o-Lixo (Ad-Lider), Dover Roll (Fort Roll) and Koleta (Colmag). Ad-Lider Embalagens, SA was planning on introducing a new product line of handled garbage bags named as Fecha Facil. They wanted to know the preferences of target audience so that the impact of such attributes can be used for the deduction of success rate for Fecha Facil. Since a huge amount was invested into this product, thus they wanted a good return as well. The research conducted was comprised of mainly individual and focus group interviews in the market to be tested.
EYE13WB-1.1 Explain the role of the early years practitioner during: • nappy changing • toilet training • washing and bath time • skin, teeth and hair • meal time It is very important to establish a routine as an early year practitioner. Routines will support the physical care needs of children. It should provide a predictable and well-ordered environment, children know what to expect. They are comforting and provide regularity, especially for babies as they enable them to adjust to their own body rhythms.
To accurately determine this, each trial will have recorded dependent and independent variables, constants and a control. The hypothesis being researched, indicates higher temperatures allow for a rapid rate of dissolution. In this particular case with someone needing Alka Seltzer, they will feel better faster if they use hot water to dissolve the medicine before
School Dress Code is Sexist School dress code has gotten out of hand, limiting young girls and boys on what they can wear to school. Telling young women that they are distractions in class because of what they wear. Girls get sent home because of their outfits it makes it seem like the administration is not worried about whether or not they get an education. Many types of clothing d or that have such as leggings, low cut shirts, and shorts have been banned or have restrictions. It is hard to find clothes that meet all these requirements.
Independent Variable amount of substrate (sucrose) present 3. Controlled Variables temperature, pH, sucrase + sucrose incubation time 4. Describe what is measured as an indicator of sucrase activity and why this is an indicator of sucrase activity. I believe glucose and fructose was used as an indicator because they are what produces sucrose and sucrose creates more sucrase activity.
This scientific question is, does the different kind of gum increase or decrease your concentration? This question was chose because many people in the world always are looking for some tips on what helps them concentrate, and chewing gum is a very easy way to help improve concentration. The Independent Variable is the type of gum, the Control Group is Bubble Gum, the Experimental Group is the Spearmint, the Dependent Variable is test scores, the Constant Variables are same timed test, same timer, and same brand of gum. The hypothesis for this science fair project is if spearmint gum is chewed then the person's concentration will be increased. This hypothesis was picked because spearmint gum is minty and the scientist thought that maybe mint impacted the brain the most.
It is targeted at young parents wanting to use the best most trusted diaper for their baby in order to nurture them and make them feel as safe as they are in their mother's arms. It states that they are the only diaper that is the number one choice of

Expansion of venous online around the anus is usually caused by an unhealthy lifestyle and stress. National recipes based on herbs can be of great help in the treatment of this unpleasant disease. According to statistics, about one-third of humanity suffers from problems with hemorrhoids, a disease that significantly impairs the quality of life. Hemorrhoids are actually varicose veins in the anus and can be internal or external.
A lot of the incontinence is caused majorly by stress while it is also proven that it is caused by the increased pressure from the fetus that is growing and the pressure it is putting on the bladder. The growing fetus puts pressure on majority of the abdominal and lower abdominal region of a woman 's body. The pressure may temporarily cause leakage during pregnancy. Not only the pressure of the fetus, there are associations of low pelvic floor muscle strength with stress urinary incontinence during pregnancy and postpartum. Many state that the prevalence of urinary incontinence rises during pregnancy and declines after childbirth.
The dependent variable, which is the time taken for the empty muffin paper cup to touch the ground (immediately after it was dropped). This will be measured using a stopwatch, which will start when the paper cup is dropped, and stopped when the paper cup touches the ground. This will be done on table, preferably inside a science laboratory. (The table will be parallel to the muffin paper cup).
DIARRHEA Definition and Overview Diarrhea is a medical condition where the patient has at least three loose or liquid bowel movements a day. It is one of the most common diseases experienced by any age group, and is especially common in children. The most significant complication of diarrhea is dehydration. Dehydration is a condition resulting from massive loss of body water and electrolytes. When diarrhea ensues, body fluid and electrolytes are eliminated by the body before they are adequately absorbed.
