An error that could have been present during the lab includes not letting the zinc react completely with the chloride ions by removing the penny too early from the solution. For instance, the percent error of this lab was 45.6%, which was determined by the subtraction of the theoretical percent of Cu 2.5% and the experimental percent of Cu 3.64% and dividing by the theoretical percent of Cu 2.5%. This experiment showed how reactants react with one another in a solution to drive a chemical reaction and the products that result from the
Introduction The purpose of this report is to summarize what our team, the Fig Neutrons, did for the final project of ECE160. For the project we used an Arduino Sparkfun Kit to build a Simon says game with multiple game modes that would display several different game statistics on an LCD screen. The work the team has done includes Charlieplexing LEDs and including code for implementing the LEDs, writing code for a reverse Simon game. We also had to make the game play a different song than the one provided, and write code for the LCD to display wins, losses, game length, and the number of games played.
Throughout the experiment, copper was altered a total of 5 times, but after the final chemical reaction, solid, elemental copper returned. Each time the solution changed color, a precipitate formed, or when gas appeared, indicated that a chemical reaction was occurring. For the first reaction, copper was added to nitric acid, forming the aqueous copper (II) nitrate (where the copper went), along with liquid water, and
THHS implements a program which emphasizes mastery in the humanities, math and science, with an emphasis on the classics, and requires its students to display the leadership skills, discipline and work ethic expected by the most demanding colleges and careers. All classes are honors, Advanced Placement or college-level, and advanced elective courses are available in all subjects. The school strives to implement their humanities-based approach to excellence through extensive literature and writing courses, advanced courses and electives in English, social studies, modern and classical languages, math, science, social science and science research, as well as a required Queens College humanities seminar. All students are required to study two years of classical Greek or Latin. Students take eight academic subjects each semester, one more than the usual high school program.
Introduction: The purpose of this experiment is to demonstrate the different types of chemical reactions, those including Copper. There are different types of chemical reactions. A double displacement reaction is a chemical process involving the exchange of bonds between two reacting chemical species. A a decomposition reaction is the separation of a chemical compound into elements or simpler compounds and the single-displacement reaction is a type of
II The book describes African Americans in the time period of slavery through civil war and civil rights revolution, to 1980s, after the segregation of the black race. The book mainly focus on the speech done by social activists of different time period. In addition of the reasons and different beliefs of those social activist had. Such as Frederick Douglass, who believe we can’t wait for somebody else to fight freedom for us.
The music video for Beyoncé's song "Formation" is an example of the intersectionality of race, gender, and class in American society. The video begins with Beyoncé sitting on a sinking New Orleans police car and addresses various social and political issues affecting Black women in America. The video relates to week 4’s topic of intersectionality because it discusses multiple factors that affect the lives of black women. The music video for "Formation" by Beyoncé touches upon gender and sexuality issues.
Procedure The formulation of the Technology Supported Material in Calculus 1 with Analytic Geometry is grounded on the curriculum of Bachelor of Secondary Education major in Mathematics. The completion of the course content will be achieved through the following steps: consultation with the CHED’s Policies, Standards and Guidelines for BSED major in Mathematics curriculum and examines the scope of the Calculus 1 with Analytic Geometry (core subject), followed by the administration of the achievement test, subsequently, the determination of strengths and weaknesses in calculus 1 with Analytic Geometry. The weaknesses will serve as a benchmark in the preparation and development of the material that aims to attain student’s learning outcomes
Satya Nadella is the replacement of Steve Ballmer as Microsoft CEO in 2014. He has directed the company away from a failing mobile strategy and focused on other lines of business, including cloud computing and augmented reality. In 2016, he organized the purchase of the professional network LinkedIn for $26.2 billion. Satya Nadella once said "Information technology is at the core of how you do your business and how your business model itself evolves. " This quote is significant, because it shows how Information Systems have a huge impact on the business world today.
The actual conditions which found don’t match with the expected conditions. This gap indicates a problem to be investigated. As an alternative solution of this problem is to implement the adaptive contextual learning model of integrated science by integrating digital age literacy on grade VIII students. There are four theoretical studies which related to the solution of this research problem those are: learning model, contextual learning, integrated science, and digital age literacy. Learning model is a conceptual framework that can be used as a guide by teachers in learning.
Learning to play an instrument or being able to read sheet music is something every child should learn. Taking music classes in elementary could benefit the brain development in children, often relieve stress, and help the students in understanding responsibilities, all which assist them in becoming well-functioning adults. It is amazing how much playing an instrument can get a child's brain working in so many different ways. The possibilities are endless for what can happen to a kid's brain just by taking music classes. In Source #2 it mentions nonstop about how "playing music helps kids use and improve they memory skills."
After the accident at Japan’s Fukushima Daiichi nuclear energy facility, the plant operators and public officials executed plans to keep people nearest the plant safe from any release of radiation, utilizing an emergency planning zone that extended in a 6-mile and, later, 12-mile radius around the plant. Though Japanese response proved effective in protecting its citizens while avoiding widespread displacement, some Americans questioned the adequacy of 10mile emergency planning zone used at U.S reactors. This process will involve having EPA trained experts on site that will measure the dispersion of toxic fumes in the air, how poisonous or toxic are the chemical pollution to make people sick, the type of sickness that the fumes may induce,
A way to encourage scientific enquiry in the classroom is through the use of practical investigations. In the context of thinking and working scientifically, investigations are activities where children can use their conceptual understanding and knowledge of science to find solutions to problems and questions (Skamp, 2012). Supported by Ward et al. (2006) who say that the term investigation is used for activities requiring children to make choices about what to change and measure. Instances where science lessons are practical and focus on the development skills linked with scientific enquiry and where emphasis was placed on the children carrying out investigations independently, were the most beneficial (Ofsted 2010).
If someone searches human experimentation online it will tell you that human experimentation can be broadly defined as anything done to an individual to learn how it will affect him or her afterwards. Experimentation on a human being is the experimentation of humans to help find cures and to help fight off things like illnesses or diseases. It can also help provide us with the medicine and knowledge of what medication should be used to treat the injury or illness medication treats things. Like headaches, sore muscles, injuries, and many more things. There is a lot of debate over human experimentation and whether it is right, if it works, or if it is needed at all.
Intro: Water pollution has caused so many problems to our waterways that no one really knows how to help. Water pollution caused; dead zones, oil spills, garbage floating around, and unsafe drinking water. People disagree about water pollution because, people have found ways to improve and help out the problem that water pollution has caused around the world. Others believe that that water pollution has created situations and are in the process of figuring out solutions. Marine life habitats are getting destroyed, marine life is declining everyday, how and where the garbage is getting into the oceans, and the drinking water is becoming seriously unsafe to drink.
