  • Analysis of the Academic Effects from Utilizing Analogies in General Chemistry Course Education
    Analysis of the Academic Effects from Utilizing Analogies in General Chemistry Course Education By Jason Timothy Smith A Thesis Presented to the Department of Chemistry At the University of Florida in Partial Fulfillment to Obtain A Bachelors in Science of Chemical Science Smith 1 Analogies in academic education help teach various ideas and topics. However, the usage of analogies has not been widely applied within second-level general chemistry. This project analyzed the effects and success that analogies have when taught to general chemistry students on a discussion level group size scale. During the fall 2018 semester at the University of Florida, certain analogies were taught to fifty-four students to help convey certain chemical topics in General Chemistry I (CHM2045). The progress exam scores of these students were then compared to the scores of approximately a hundred students who took the same course in the fall semester of 2017. While the exams were not identical, the structure and types of questions were similar on both. This allowed for an adequate source of data to analyze effects that the analogies might have. Several statistical tests were used to analyze the exam scores. It was confirmed that there was a statistical significance in the analogy questions but a statistical insignificance for the non-analogy questions. INTRODUCTION Mental models help convey particular theories and ideas by utilizing certain mental images to improve understanding and have been applied in many cognitive settings. One mental model seen often in everyday life is analogy. Because of their simplicity and effectiveness, analogies have played a huge role in problem solving, decision making, argumentation, conceptualization, and communication to name a few.1 Analogies work by providing a link between two different domains of meaning.

  • Chapter 10: Chemical Reactions
    CHAPTER 10 Chemical Reactions What You’ll Learn ▲ You will write chemical equations to describe chem- ical reactions. ▲ You will classify and identify chemical reactions. ▲ You will write ionic equa- tions for reactions that occur in aqueous solutions. Why It’s Important Chemical reactions affect you every second of every day. For example, life-sustaining chemical reactions occur con- tinuously in your body. Other chemical reactions occur in less likely situations, such as in a thunderstorm. Visit the Chemistry Web site at chemistrymc.com to find links about chemical reactions. The electricity of a lightning bolt provides the energy that sparks chemical reactions among sub- stances in the atmosphere. 276 Chapter 10 DISCOVERY LAB Observing a Change n indicator is a chemical that shows when change occurs during a A chemical reaction.

  • The Farewell Demos Andy Cherkas Stouffville DSS Retired [email protected]
    The Farewell Demos Andy Cherkas Stouffville DSS Retired [email protected] Edit any lab or demonstration you may wish to do for your purposes. For example take out answers so the students can think about them. Try each before having students do them or before you demonstrate them to make sure everything will go as expected. Also remember that any demonstration can be reworked into a hands on lab for students and any lab for students can be demonstrated by the teacher. Any questions about these labs and demos should be directed towards myself or another experienced chemistry teacher that you have contacts with. Demo or Lab: CORROSION LAB Problem: What are the factors that slow and speed corrosion? Materials: eight clean test tubes, distilled water, tap water, common nails cleaned to remove any oil coating, painted nails, galvanized nails, copper wire, salt, acid, magnesium ribbon, 0.10 mol/L potassium ferricyanide solution Safety: Follow general safety procedures. Procedure: Prelab all the set up so students can come in the next day and start the set up. 1. Place a common nail in tap water in a test tube, with the nail head just out of the water 2. Place a 2nd nail in a second test tube completely covered by the tap water 3. Place a 3rd nail in distilled water in a test tube, with the nail head just out of the water 4. Place a 4th nail in the test tube, completely in tap water with salt added 5. Place a 5th nail in the test tube, completely in tap water with 5 drops of acid [vinegar will do] 6.

  • Chapter 9: Chemical Reactions
    Chemical Reactions BIG Idea Millions of chemical reactions in and around you transform reactants into products, resulting in the absorption or release of energy. 9.1 Reactions and Equations MAIN Idea Chemical reactions are represented by balanced chemical equations. 9.2 Classifying Chemical Before fire Reactions MAIN Idea There are four types of chemical reactions: synthesis, combustion, decomposition, and replacement reactions. 9.3 Reactions in Aqueous Solutions MAIN Idea Double-replacement reactions occur between substances in aqueous solutions and produce precipitates, water, or gases. ChemFacts After fire • Wood has to be heated to 260°C before it bursts into flames. • Before wood burns, the water in it boils off. This produces sizzling sounds. • The smoke produced when wood burns contains more than 100 substances. 280 (t)©Robert Clay/Alamy, (b)©Terry W.
