Baggie Chemistry Experiments

Baggie Chemistry Experiments Overview An ordinary ziploc bag can unlock a world of interest in chemistry and in the reactions within and around us. In this project, safe materials are mixed to change colors and produce bubbles, heat, gas, and odor. Explore endothermic and exothermic chemical reactions and help students develop skills in observation, experimentation, and inference. These activities are targeted for students in grade 3, 4, and 5, although they may also be used for higher grade levels. Objectives The purpose is to generate student interest in chemistry. Students will observe, experiment, and learn to draw inferences. Materials These quantities are suitable for a group of 30 students to perform each activity 2-3 times: 5-6 plastic ziploc-style bags per lab group5-6 clear plastic vials or test tubes (may be used instead of baggies)1 gallon bromothymol blue indicator 10-ml graduated cylinders, one per lab groupteaspoons, 1-2 per lab group3 pounds calcium chloride (CaCl2, from chemical supply house or from store selling this type of road salt or laundry aid)1-1/2 pounds sodium bicarbonate (NaHCO3, baking soda) Activities Explain to the students that they will be performing chemical reactions, making observations about the results of these reactions, and then designing their own experiments to explain their observations and test hypotheses that they develop. It may be helpful to review the steps of the scientific method. First, direct the students to spend 5-10 minutes exploring the lab materials using all of their senses except taste. Have them write down their observations regarding the way the chemicals look and smell and feel, etc.Have the students explore what happens when the chemicals are mixed in baggies or test tubes. Demonstrate how to level a teaspoon and measure using a graduated cylinder so that students can record how much of a substance is used. For example, a student could mix a teaspoon of sodium bicarbonate with 10 ml of bromothymol blue solution. What happens? How does this compare with the results of mixing a teaspoon of calcium chloride with 10 ml of indicator? What if a teaspoon of each solid and the indicator are mixed? Students should record what they mixed, including quantities, the time involved to see a reaction (warn them that everything will happen very fast!), the color, temperature, odor, or bubbles involved... anything they can record. There should be observations such as:Gets hot Gets coldTurns yellowTurns greenTurns blueProduces gasShow students how these observations can be written down to describe rudimentary chemical reactions. For example, calcium chloride bromothymol blue indicator heat. Have the students write out reactions for their mixtures.Next, students can design experiments to test hypotheses they develop. What do they expect to happen when quantities are changed? What would happen if two components are mixed before a third is added? Ask them to use their imagination.Discuss what happened and go over the meanings of the results.

5B - Essay Example This seems to be an inconsistency in her behavior. While it is true that she is probably a very naà ¯ve little girl, even toddlers are made aware of significant dangers to avoid, such as large wolves appearing from the forest. If she is old enough to take food to her grandmother, Little Red Riding Hood is also old enough to know better than to fraternize with wolves. An alternate goal of this story might be a classic set-up job. The wolf refuses to attack children in the village where the men can easily attack him and thus rid the village of the danger he poses. At the same time, it is known that the wolf prefers young children and he is likely to go after Little Red Riding Hood if she is sent off to her grandmother’s house. If the little girl is instructed by the hunter to first tell the wolf where she’s going, the hunter can be sure to find him, making it possible to kill him. If the hunter was obliged to follow a discreet distance behind Little Red Riding Hood to be sure the wolf didn’t attack her on the way to her grandmother’s house, not knowing the wolf would run ahead and await the girl at the cottage, this would explain his late arrival and his failure to warn the old woman. In the fairy tale Rapunzel, there is no clear goal as to why the witch might demand an unborn child in exchange for the theft of some vegetables out of her garden or why she might lock the girl up in a tower once she becomes of marrying age. Associations of her as the overprotective mother are refuted by her complete refusal of Rapunzel once she learns of the prince, which should have meant a happy match for her ‘daughter’. Instead, I see the witch as obsessively consumed with ensuring she is provided with company until the end of her days. If the witch was growing the rapunzel plant as a needed ingredient for a cure for a loved one who is lost as a result of the stolen plants, this

Earning a College Degree Essay Example for Free

Earning a College Degree Essay Earning a college degree has always been a very important goal of mine. My children are getting older and in a few short years will start looking into college themselves. It became more important for me now than ever to make my dream, my goal, a reality. There were many factors that came into play when I decided that this was the right time in my life to return to school. Being a non-traditional student, cost, flexibility, and accreditation were among the most important factors for me when choosing an online university. As my research into finding the right university continued, I found that Western Governors University had much more to offer their students than just an education. The financial aspect of returning to school was probably my biggest concern. I wanted to earn a degree, but didn’t want to be left with a hefty student loan payment at the end. Many of the online University’s that I looked into were â€Å"for profit† schools. Being inexperienced and new to this research I didn’t realize that there was such thing as a â€Å"non for profit† online University until I stumbled upon WGU. With affordable tuition, I knew that my dream could soon become reality. My children and husband are my number one priorities. They always have been, always will be. My time spent with them is precious and something that I would not give up for anything. The flexibility in classes and coursework that WGU offers has given me the perfect balance to be both a mother and a student. Since WGU is a competency based school, this allows me to spend less time on the material that I already know and concentrate more on the subjects that I am not as familiar with. Accreditation was another important factor for me. I didn’t want to spend the next 3 to 4 years going to school, spending countless hours reading and studying, only to find out that future employers would not take my degree seriously. Finding out that WGU is highly respected among businesses made my decision that much easier. There have been a few unexpected surprises along my journey thus far, with WellConnect being one of them. I never realized how much an online university could care about the health and wellbeing of their students. WGU also has some great mentors who not only offer encouragement, but push you to do the best and be the best that you can be. From my first inquiry of Western Governors University to now, I can say that, without a doubt, I made the right decision. I have finally found an online university who is just as committed to my success as I am. I would encourage anyone thinking about  returning to school as a non-traditional student to look no further than Western Governors University. With their low-cost tuition, flexibility, and accreditation to their amazing and caring mentors and their competency based program, WGU is definitely a perfect fit.

The Importance of Education in Preventing Prejudice Essays -- Importan

Ignorance is a huge problem, it is one of the biggest factors responsible for issues such as racism and sexism. Luckily, ignorance, generally speaking, is a relatively easy issue to fix. The obvious answer here would be more education, but this is not necessarily the case. In order to eliminate much of the racism, sexism, and other forms of prejudice that arise due to ignorance, it is necessary to look at education from another perspective: one that encourages togetherness and development alongside people of all races and genders. One quote by Grace Boggs book The Next American Revolution summarizes the issue perfectly. â€Å"Just imagine what our neighborhoods would be like if, instead of keeping our children isolated in classrooms for twelve years and more, we engaged them in community-building activities with the same audacity with which the civil rights movement engaged them in desegregation activities fifty years ago! ...Our children will be absorbing naturally and norm ally the values of social responsibility and cooperation at the same time that they are being inspired to learn the skills and acquire the information necessary to solve real problems† (Boggs 158). So, the main point here is that prejudice, against all sexes, genders, and creeds, can be eliminated via education that encourages cooperation with the largest variety of people. In order to understand this concept, it is necessary to look at it from a few different perspectives to analyze its viability in modern society. First, it is necessary to examine the current paradigm within education in order to determine exactly what it is about the modern system that requires changing. One of the most immediate concerns comes as a result of the school facilities the... ...r through the power of music, will not be forgotten. Racism, sexism, and other forms of prejudice are simply not acceptable in modern society, and the sooner they can be eliminated altogether, the sooner the world can truly advance.

Entrepreneurial Organization Essay

In Business today the Entrepreneurial Organizations continue to grow, thrive and help change the way companies and people do business. These Entrepreneurial changes that happen internal to large organizations or at small start-up companies all have some of the same traits in common with each other and use some of the same tactics to create business opportunities. Some of the traits they share to promote their business are: Individual action and initiative, Innovation, Differentiation and Risk Taking. Individual action and initiatives taken by the employees within the organization are to create new product offerings or enhance existing products. These actions do not always succeed in creating revenue for the business, but might help start another product line that will create revenue in the future, but the failures of these products is not seen as a negative within the organization but are treated as growth and are seen as positive steps. Innovation is a primary and necessary building block for the entrepreneurial organization. There are 2 types of innovation that should be looked at, used, changed and viewed when using innovation and these are Product and Process. These types of innovation will create change in either a product or process but both are essential to using innovation within the organization and will be used to create new ideas, process and test new theories. Differentiation is another advantage that has to be used, displayed and shown for an entrepreneurial organization. This shows the advantage to customers and investors what unique good, service, talent and innovation that the organization has that makes the customers willing to pay a premium for their services. Risk taking from a large or small organization requires some sort of investment on the part of the company, either in personal resources or financial resources. The level of risk that the organization is willing to support shows the employees that the organization is willing and able to make changes if the risks are worth the reward. But risks must be taken in these types of organizations to create and discover new opportunities. In conclusion, these are four reasons why entrepreneurial organizations seek to use innovation to create new opportunities and are  some of the building blocks for many large and successful companies. With the landscape of business always changing, if companies are not willing to use innovation to try and create new opportunities they might not be successful in the future.
