Science Fair Lab Results

C. An unknown, rectangular substance measures 3.6 cm high, 4.21 cm long, and 1.17 cm wide.

The experiments conducted for this lab report focused on water contamination and filtration. Experiment 1 was effects of groundwater contamination. Oil, vinegar, and laundry detergent were added to clean water with no means of filtration. The clean water was found to be contaminated. A filtration system consisting of cheesecloth and 60 ml of soil was created and the contaminated samples were filtered through it. The soil and cheese cloth did not affectively filter the contaminants. Experiment 2 focused on

The problem that needed to be solved for this experiment was, “How are organisms able to survive and function with proficiency despite metabolic activities that have the disastrous ability to alter pH from a neutral to an acidic or basic environment?” This question needed to be answered by testing different biological materials, as well as tap water, in order to find out what allows modern day organisms to survive such hazardous conditions. A hypothesis that was formulated before experimenting was, “If type of substance is Tap Water, then the changes in pH will be more drastic because water, considered neutral on the pH scale, doesn’t contain a component that will prevent such a change, unlike the content of a buffer solution.” The independent variable for this experiment was type of substance, evidently because this was the part of the experiment that was constantly being changed from trial to trial. The dependent variable for this experiment was pH of the substance because the pH constantly changed depending on the type of substance was being experimented with. The control of this experiment was the tap water and buffer solutions, as the results of the data from the biological materials were constantly compared to the data from both of these solutions.

To develop an understanding of the metric system and use it to measure common objects. To also learn about how to report uncertainty in your measurements.

October 17, 18, and 19, samples were collected from multiple sites along the BSR. The class was split into groups, and samples were collected from seven separate locations along the river and WWTP. There was also a sample collected by the S which is located between sites four and five. For each of these sites, there were ten groups from other labs that also collected a sample from the BSR. At site two of the river, the location included multiple sources of possible contamination. A drainage site was located 200 yards upstream, along with a small PVC drainage pipe next to the collection site. Not only was there drainage running into the river, the site was under a bridge, and contained other trash scattered throughout the area. The

Aquatic organisms use oxygen just like terrestrial organisms. The oxygen percentage of the atmosphere is approximately 20%. The oxygen percentage of water is much lower, at 1%. Many factors affect how oxygen and other gases dissolve in water. The purpose of the experiment was to discover if temperature is a factor for gases dissolving in water. In a beaker, 225mL of water was filled at varying temperatures between 0 degrees Celsius and 65 degrees Celsius. Three 12cc capacity syringes were filled with 7cc of Diet Mountain Dew, the syringes were then pointed upward, pressed of excess carbon dioxide leaving 5cc of seltzer, capped, and plunged into the water. A stopwatch was then used to time for three minutes, after which the syringes were removed

(INTRODUCTION) The scientific method is the procedure used to either ask or answer questions, the components of the scientific method include: observation; which is watching something that peaks your interest, then you must develop a hypothesis; this means that an individual has to make an educated guess for the observation, afterwards an individual must define a question; meaning answering the who, what, when, where and how, ( Simms). The reason for doing the experiment was to figure out through deviation and the class average from the data gathered if the pipette or the graduated cylinder would be able more accurate in measuring the volume of water. Before beginning the experiment my hypotheses was that if I weigh the water in the two different

The purpose of this lab is to test substances and to determine the physical and chemical properties of substances.

The aim of my experiment was to figure out how different chemicals affect surface tension. I chose this experiment because I have always wondered how a drop of water stays together as it falls through the air. My independent variable was the different chemicals used. My dependant variable was which liquid stayed on the penny best. The control in this experiment was pure water. My hypothesis was; if water mixed with salt and water mixed with detergent is tested, then detergent will cause the surface tension to weaken the most.

The purpose of my science fair project is to show that kids are more than just their labels. At the beginning of my project I did research on labels and how they affect students at school and at home. Later on I made a 2 test which one was visual and the other was read out loud. I tested on as much people as I could. After a couple of weeks I analyzed my data and divided what into groups. I did the same tests on every person no matter age or grade.The results I got were very impressive students that were looked as the “bad kids” or “not smart” kids, got the best grades on the test versus the kids that are seen as the smart ones got lower scores. These results show that students are more than the labels given there's is more to us than what

The topic is the differences between bar soap and synthetic detergent. In this experiment the scientists will be testing if detergent remove stains better than soap or it's if the other way around. The independent variable will be Dial liquid soap and Tide detergent. The dependent variables will be the degree of cleanliness after washing the stains off and the unit that will be used are photons measured with a spectrophotometer. The constants are going to be: same amount of soap being used, same type of fabric (white shirt, brought from the same store, same price and brand.) during the will also use the same amount of water in order to wash the pieces of shirt and they will be left drying

The goal of this experiment was for students to create 6-8 labs to discern among four different clear substances, which is water. Students tested and observed for evaporation, smell/observation, viscosity, surface tension, density, and created two of their own to compare to the control in the experiment. Each lab was created to observe the properties of water. It was imminent that water is a solvent due to the tea grains, has capillary action due to its ability to rise into the cotton ball, evaporates when in the presence of heat, and is far more dense than oil.

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.

Prior to doing the lab investigation, the students will sketch graphs predicting what the force and spring stretch relationship will look like. Their graphs will demonstrate that the students that their data will need to support or reject their initial predictions; more importantly, the students will get an idea of what data to gather to support or to change their predictions. Once the students have finished plotting their data, they will share their findings with the class by explaining the relationship that their data indicates. To ensure that all students understand the importance of the learning targets, they will explain to one another why it is important to become skilled in data collection and in data analysis; they will also get to

I have many goals for this month, but my main goal is finishing my science fair project research. It is necessary that I finish this before fall because the clams I am researching on will perish when it gets cold. To do this, I will finish four of my six research sites this week. Then, if it suddenly gets cold, I will have some results. If the weather holds out, I will do two more sites next week. Then, I will have all my research done for Science Fair, and all I will have to do is make it presentable.
