Investigating Properties Lab Ishan Godra SCH4U Lab Partner(s): DeSean Lawrence Ms. Boulougouris 10/31/14 Purpose The purpose of this experiment is to analyze the properties of four different types of solids: ionic, polar covalent, non polar covalent, and metallic Hypothesis It is hypothesized the samples which are shown to be insoluble are likely non polar, while soluble samples are polar. Because of the molecular nature of each type of bond, it is hypothesized that polar covalent molecules It is hypothesized that the samples which are insoluble in water are likely to be non-polar molecules or network covalent and the samples which dissolve are either ionic or polar molecules to have dissolved in the water.…
Nettie Stauts January 26, 2018 CDT-2413 Module 1 Lab Parents Perspective: The parents were apprehensive, but eager, entering their son Luke in a child care program. They were getting early intervention home-centered services in which Luke had progressed with assistance from his therapist and babysitter. He lacked social developmental skills and they heard about inclusion although unfamiliar with the concept. They were adapted interacting with Luke through gestures and augmentative communication devices yet anxious about his communication in the classroom.…
Experimental Conditions It is important to note that in our lab experiment we used galena, PbS, with 170 – 200 mesh (i.e. there were 170 to 200 wires per inch of sieve used to sort out the galena crystals). This means our diameter range of our particle size was 75-90 μm. Table 1:Experimental Conditions for PbS leaching FeCl3·6H2O (g) to be added is found by: The weight of FeCl3·6H2O (g) added in our experiment was slightly larger than the theoretical amount of FeCl3·6H2O needed, as can be seen from the example equation below:…
This experiment does show and follow the law of conservation of energy by turning potential energy into kinetic energy. cannot be created or destroyed, but only changed from one form into another or transferred from one object to…
"Energy Story", "Hands-On Science with Squishy Circuits" and "Conducting Solutions". All very informative sources about electricity and how its conducted. In Energy Story what the author is explaining the basics of the science behind the amazing process that allows us to have electronic instruments that run on this source of energy. The purpose of the article "Energy Story", is to inform the reader about the scientific force behind this process, and what goes on when we flip a light switch. It also reviews the many components of the atoms or ions, that are involved in the flow of electricity through a circuit.…
Jessica Vandeventer April 13, 2016 Energy Comparison of Fuels Purpose/Question- The Purpose of the lab is to see a comparison of fuels using a home made calorimeter. Hypothesis– The burner fuel is going to be a better source of fuel than the tea candle. Data Tables/ Graphs – Data Table 1.…
The experiment began with a reaction of a 1cm3 cube of lamb liver and 5mL of hydrogen peroxide solution being put in test tubes in a beaker filled with 10℃ water until the temperatures of the liver and hydrogen peroxide were 10℃ also. The liver was put into a 100mL measuring cylinder and the hydrogen peroxide was also poured in as the timer was started. After twenty seconds, several millilitres of froth had been produced from the chemical concoction. This froth was recorded into a results table, and the previous steps were repeated but with increasing temperature increments of 10℃ until 50℃. After carefully completing the experiment, the final results obtained by measuring the volume of the froth produced after 20 seconds, were recorded in a table - see Table 1, and able to be observed in a graph, see Figure 7.…
Input- Energy used to play with it. Output- Emotions and the ending conclusion of the game Process- The soccer ball is made in a sphere form and stitched with pvc (Poly Vinyl Carbonate) and/or leather for a great amount of exercise and resulting in a fun team sport. The ball rolls and usually stays on the ground.…
Ms. Francis was just discussing the final project for AP Physics C that was due at the end of the week. It had been two weeks since the group project had been assigned, and Barry Wolfe’s group had yet to even start on it. The project was worth 20% of his final grade, and Barry needed a one hundred in order to get an acceptable grade in the class. Barry’s father, Hrobert, has not shut up about the importance of good grades in order to get into college. A college Barry can only get into if he aces this project.…
Neurons are one of the most important cells in living animals. There are billions of neurons throughout our bodies, especially the brain which is the control house of the body. Neurons are what help us see, hear, taste, and feel sensation. This is all do to a critical phenomenon known as action potential. Action potential is caused by a change in various ions, specifically sodium and potassium.…
All the rules for soccer are in effect while the ball is on the ground. In order to get a “ground ball” into the air, a player has to kick the ball up into the air. A method of moving the ball from the ground into the air is by using some…
Introduction Actual rocket ships use chemical reactions to lift off into space. Using baking soda and vinegar we can simulate a rocket taking off because when mixed together, a chemical reaction occurs. By changing the amounts of the chemicals we can determine which will allow the bottle rocket to go farther. Chemical Reaction Vinegar is an acetic acid.…
By using the pseudo first-order kinetics method, you are able to determine the rate law for the reaction between crystal violet and hydroxide ion. crystal violet hydroxide CV+ + OH- ————> CVOH Rate=k[CV+]m [OH-]n The objective for this experiment was to analyze the absorbance of the dyed molecule crystal violet using a colorimeter and the molar absorbance of the reactant. This data was used to calculate the concentration of the the crystal violet and hydroxide ions.…
Multiple different training techniques are incorporated and three different energy systems are present for a soccer player to achieve optimal performance. Muscle Groups Used The lower body. The legs are the primary muscle involved in soccer.…
My steps inched closer to the ball until my plant foot reached the left side of the ball. In that moment, every sound turned to nothing, my kicking leg swung forward in slow motion, and feeling of my own heartbeat felt as though it was about to beat right out of my chest. The contact with the ball and my right foot was weak. My own knowledge of how to properly kick a soccer ball had skipped out of my mind. My foot skimmed over the top of the ball, causing it to slowly dribble to the right side of the goal.…
