Lab Report Investigating Mixtures
On Thursday, September, 28 in Ms. O’Brien’s Honors Science class we conducted two experiments the Mixed Substances Lab and the Investigating Mixtures Lab. The objective of the Investigating Mixtures Lab was “To observe that not all liquids behave the same way when mixed with other liquids”. Before we started the lab we we each created a hypothesis mine was “If the water and vegetable oil are mixed and the two combine and make a mixture, then the vegetable oil will float and the water will sink”. This is the important information which we must solve to determine whether our hypothesis was correct.
After conducting the first lab we conducted our second lab the Mixed Substances Lab. The objective of this lab was “ To see how properties of individual

    Each substance was observed inside their containers and the hypotheses were based on these observations. The volumes of each substance was then measured inside their containers. Each substance was then weighed and density calculated. After, each substance was observed under magnifying glass, smelled and touched to determine texture. Lastly, each substance was tested for solubility.…

    After examining seven additional substances, there were many pieces of evidence that help conclude that the mystery mixture ( number 8) is composed of citric acid and sodium bicarbonate the same as mixture six . At first when just observing the dry mixtures, it was hard to determine which ones were identical to the mystery mixture. In order to figure out which substances combined to make the mystery mixture, another process we followed was adding water to the substances and observing the reaction. Adding water to the mixtures resulted in a chemical reaction. The materials fizzed and bubbled due to the reaction.…

    An unknown sample, # 12-Green, was separated into its individual variable components, iron, ammonium chloride, silicon dioxide, and sodium chloride. The techniques used to separate the components of unknown # 12-Green, magnetism, sublimation, extraction, and filtration, were chosen based on the unique properties of each component. Using these separation techniques, each substance was extracted and the composition of unknown # 12-Green was 16% Fe, 15% NH4Cl, 59% SiO2, and 9% NaCl with a 1% uncertainty due to the loss of 0.0369g of the initial mass.…

    In the article “How Boys Become Men”, written by John Katz, he analyzes situations he experienced while growing up. Katz believes that boys become men by not showing fear or feelings and not ratting on others. As in the novel, The Other Wes Moore, both Weses are forced to become men at an early age. They experience events that push them to make decisions that make them grow and think like men do. Katz details the maturation process for boys, as the book, The Other Wes Moore, does with both Weses. They make decisions and take actions to mature and become a men.…

    Students at NFV middle school are on a journey to figure out a mystery mixture. They have to search through 9 chemicals to figure out which one is it. Seems easy huh? Nope, they have to analyze the physical and chemical properties (a very important part in this), the data, argue, and give important statements on what they think is in the mix. That’s when arguing comes in, not arguing on the person but the statement. I think it is citric acid and baking soda.…

    The first step in this experiment was to ask a question. My question was what is the identity of the six unknown substances? The second step was to create a hypothesis based on what I already know about each unknown substance. Third step was to test my hypotheses by using six methods. The first method was to determine the color of each substance. The second method I used was to calculate the density of each substance. I did this by first estimating the volume and then weighing each substance with a digital scale. To calculate the density I divided the mass by volume. The third method is to use the magnifying lens and look at the shape of each substance particle. Along with determining the shape I also recorded the texture and smell for each substance. The last step was to text the solubility of each substance. I did this by mixing each substance in 6 different test tubes with 5 ml of distill water. I shook each tube to see if the substance dissolved. After completing all 6 steps…

    The purpose of this lab was to determine whether the type of solvent will change if sugar can dissolve in it. For this experiment, 50 mL of water, rubbing alcohol, and vegetable oil were poured into different beakers with 1 gram of sugar and stirred for a minute to see if the sugar has the ability to dissolve within the solvent. It was hypothesized that if the solvent was changed, then there would be different amounts of sugar that can dissolve in it. During the experiment, it was discovered that water was the only solvent to dissolve the sugar while in the other two, the sugar sank to the bottom and did not dissolve. The hypothesis was only partially correct. That is because the sugar dissolved in the water while it…

    On our first trial, we only put in blue, green, red, and yellow mixtures inside the test tube. Before we even put in the orange solution, the yellow liquid started to mix in with the red solution. It meant that the yellow sugar water was more dense than the red sugar water. On our second trial, we tried to put the green mixture first to see what would happen. When we put the green mixture inside the test tube, we decided to experiment and put in the yellow solution. The second we put the yellow mixture in, it immediately mixed in with the green. This proved to us that the yellow mixture was more dense than the green mixture. Next, we tried to put the blue solution first, the green solution second, the red mixture third, the yellow mixture next, and the orange sugar water on the top. The test tube started turning a dark purple color. The orange was more dense than most liquids. Then, we tried blue, green, red, and orange. The red and the orange mixed and the mixture turned black. On our final trial, we did blue, orange, green, yellow, and red. The sugar waters did not mix in this order. The blue was the most dense. The orange was not as dense as the blue, but was more dense than the green. The green was more dense than the yellow, but was not as dense as the orange. The yellow was not as dense as the green, but was more dense than…
