Each student is assigned one of many different elements that are necessary for the health and well being of the human body. They then have to research the effects that their element has on the body, and discover which foods are rich in that particular element. I assign elements to my students by placing the name of each element listed below on a small piece of paper. These pieces of paper are then placed into a large beaker an Read More Go to Site 80.07.12: A Problem Solving Approach to the Introduction of Chemistry Votes:0 Yale-New Haven Teachers Institute Home A Problem Solving Approach to the Introduction of Chemistry by Thelma Stepan Contents of Curriculum Unit 80.07.12: Narrative Objectives Vocabulary Properties of Matter Bibliography To Guide Entry This four to six week unit is to be used to introduce chemistry to college bound high school students. Their reading ability is generally on a high school level and their math background varies from algebra I to pre calculus. Chemistry is usually the first subject these students encounter which requires the application of the various math skills they have been exposed to over the years. They usually tend to compartmentalize their learning experiences, and to leave their math neatly filed away for math class, or semiforgotten.

The best analogy for understanding the mole is the dozen. Students intuitively understand a dozen is equal to the number 12, and that the weight (mass) of a dozen will depend on what you have a dozen of. Students will therefore start by calculating mass to dozen relationships and then progress to mass to mole relationships. Background: Students need to be familiar with the conversion factor method of solving problems and understand the importance of keeping track of the units in a calculation.

First you will study the Periodic Table of Comic Books to find some interesting and amusing misconceptions about chemistry. If you do the Additional Activities, you'll look at some unusual, but workable, ways in which periodic tables are organized and compare them to the structure of the standard periodic table. The standard long form of the periodic table appears on the walls of almost every chemistry classroom. However, it's not the only way that the elements can be arranged. The familiar periodic table is the end result of the creativity of several European scientists in the 1860s. The Russian chemist Dmitrii I. Mendeleev is generally credited with the insights and creativity that led to the Read More Go to Site PH@School: Addison-Wesley Chemistry: Chapter 27 Internet Activity Votes:0 What is Caffeine and Why Is It So Popular? Caffeine is a biologically active molecule found in many foods and drinks including coffee, tea, cola drinks, and chocolate. It is, by far, America's most popular drug. About 90% of Americans consume caffeine daily in one form or another. More than 50% of American adults consume about 300 milligrams of caffeine per day, which is recognized as more than a moderate amount. Caffeine is an addictive drug. Although far more mild than drugs like amphetamines, cocaine, and heroin, caffeine uses the same mechanisms to stimulate the brain. Caffeine provides an "energy boost" or a feeling of heightened alertness. It's often used by people like students and truck drivers who need to stay awake late into the night. Many people feel the need to have a Read More Go to Site PH@School: Addison-Wesley Chemistry: Chapter 8 Internet Activity Votes:0 A Balancing Act One of the greatest difficulties in learning chemistry is to visualize the particulate nature of matter and relate macroscopic observations of our world to the submicroscopic world of atoms and molecules. Chemical equations are a symbolic way to represent the changes matter undergoes in terms of submicroscopic atoms, molecules, and ions. For example, water can be broken down to the elements hydrogen and oxygen by electricity. This change is called a chemical reaction and its symbolic representation is a chemical equation. The coefficients in front of the formulas H 2 O and H 2 serve to balance the equation. They ensure that the same number and kind of atoms appear on both sides of the equation. 2H 2 O 2H 2 + O 2 In this Internet Activity, you will practice writing chemical Read More Go to Site Physical And Chemical Changes Votes:0 Physical And Chemical Changes Physical And Chemical Changes Carolus Love Hoyne School 12535 S.

DESCRIPTION This experiment is most appropriate for a first-year college prep or AP class if done quantitatively. If done qualitatively, it would be appropriate for a general class. One of the most important applications of electrolytic cells is the process of electroplating, in which a thin layer of metal is deposited on an electrically conducting surface. In electroplating, the metal to be plated is used as the anode and the electrolytic solution contains an ion derived from that metal. In this experiment, a copper anode (US penny) will be used in a solution of copper sulfate. Copper will be plated out onto a second penny at the cathode.

It will show that in a chemical reaction where a gas is produced, the mass does not change. The mass does not change provided none of the gas is allowed to escape. This will give evidence for conservation of mass. In furthering their knowledge of the laws of conservation of mass, the loss in mass can be accounted for, when the gas is allowed to escape from the container which it is produced in. This will prove that gas does have mass.
