They can be identified by a color change, if a new gas is given off, if a precipitate or new solid forms, and if light, electricity, or heat is given off. b. observations- The observation that was made was that there was going to be many different experiments set up. Each of the experiments that were going to be set up would have a chemical change or physical change take place. c. purpose-The purpose of this experiment is to find out how to differentiate a…
We also wanted to discover as many chemical and physical properties as possible. Physical properties are those that can be determined without performing any changes to the identity of the substance. Chemical properties are properties that can only be determined after a chemical reaction is performed in order to change the identity of the substance according to “Physical”2…
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.…
Instructions: Buddy Lab - Physical and Chemical Change You’ve learned a lot about matter lately and now is your chance to teach someone younger about what you know. Your job is to design a lab that will help a primary student experiment and understand what physical and chemical changes are. Follow the guiding questions below to help you create your lab. Question:…
Learning Objective: After modeling for a class and practicing portioning shapes into two equal parts as a class, students would be able to portion circles and rectangles into two equal shares, with 80% accuracy. Applicable Common Core Learning Standard: CC.4. MD. 3 Apply the area and perimeter formulas for rectangles in real world and mathematical problems.…
In the basement of Temple University’s Tyler School of Art is where Pepón Osorio’s installation reForm is located. The installation reForm is in lieu of the Fairhill Elementary School in North Philadelphia. This installation was to show viewers how Philadelphia’s budget cuts can greatly affect children and their education if school were to be forced to close. Pepón Osorio makes a very powerful representation of the issues of school budget cuts that arise via Fairhill Elementary. Osorio is known for his ultra-baroque methods when creating his works of art.…
The object that I chose to describe to my friend over the phone was a Darth Vader coffee mug. I started describing the object by its color, which is black and it is also shiny. I use it mostly during the morning time. That should have been a good indication that it was some part of a morning routine. I informed my friend that it is breakable and that it needed to be cleaned after every use.…
History of Wands Wands have a long and rich history throughout time. From the first wand of the Egyptian priests and rulers using ivory amulets to todays wand made from magical trees and other magical materials, there have been many creations and re-creations to arrive at the semi-sentient object, we call wands. In Canada, the First Nations people had their own spiritual magic. Once the European wizarding community arrived, they brought their history and their wands. In 1722, Decusroggan was born to an Englishman and a Cree woman.…
Although this research is not life or death, it is of utmost importance to understand how other animals think and react to the world around them and would be relatively simple to incorporate into existing studies. Understanding if other animals recognize false patterns will not gain humans a cure for cancer or end world hunger, but it will advance human knowledge. Obviously more funding should go to the most crucial research, but it would be simple and cost efficient to include false pattern recognition test into existing research studies. Although it is not possible to say for certain that animals do have false pattern recognition, because enough reliable research has not previously been conducted to come to a scientific conclusion, the quality…
However, the same wax remains. Therefore, our awareness regarding the solid wax and the liquid wax being equivalent…
There are many important objects that people use on a day to day basis. Whether the object would be a car that is used to get around places or a cell phone which gives you access to connect with your close ones. These objects are a reliable source to one’s self because it get them through the day including mine. Even though writing about either one of these objects will be an interesting task, I decided to choose any everyday object that has a deeper meaning to me. The object I’ll be speaking about in my essay is my crucifix necklace.…
The evaluation of an object without the visual concept can be difficult for some people, since they experience the internal process where frustration, anxiety and boredom are a barrier from concentration. The assignment that we did consisted in bringing to class an unfamiliar object in a bag so anyone could see it in order to describe the object in details without the visual concept. We exchange the object with someone else who did not know what the object was. My partner gave me her object inside her glasses case; so I decide to close my eyes and try to describe the case also as part of this assignment since I did not see it in details. After I received the object I put it under my desk and open the case.…
Discussion There were four goals for Project 11: Identification, Properties, and Synthesis of an Unknown Ionic Compound. The first goal was to identify the unknown compound, the second goal was to determine the reactivity of the compound, the third goal was to determine the quantitative solubility of the compound in water, and the fourth goal was to find the percent yield of a product from a reaction involving the unknown compound. Determining the identity of the unknown compound was achieved by performing a variety of tests for the physical properties of the substance. Some of these properties, such as melting point and chemical structure, could be discovered by making a few immediate observations of the substance. The unknown compound…
American Sign Language is a unique language with diverse syntax, semantics, pragmatics, and morphemes, which includes grammatical aspects which are not present in English including classifiers. Despite the limited research in specific areas of ASL, due to ASL not being officially recognized as a language until 1960, the importance of classifiers is indisputable. Classifiers are “designated handshapes and/or rule-grounded body pantomime used to represent nouns and verbs” by representing a class of things with a shared characteristic (Aron 1). They can express many different key pieces of information and are an extremely complex aspect of ASL grammar. Classifiers are essential to nearly all levels of storytelling, making both receptive and expressive…
We have decided to study the centration theory by testing 6 years old identical twins with various conservation tasks in order for us to study their dimension of centration theory. We would like to prove whether the theory is applicable to the twins and do the twins answers for the conservation tasks is the same as what has been proposed by Piaget centration theory? Conservation is one of the terms of Piaget which mean the ability to understand the measure of two objects still constant even though their shape changed as long they do not take away or add the measure and content of the object, (Feldman, 2012) This measurement can be in volume, mass, and number length.…
