Lab: Reactions of Copper
Students perform a series of experiments on copper to produce a variety of copper compounds. In this chemical reactions of copper lesson plan, students use copper wire and nitric acid to produce copper nitrate. They then form a hydroxide followed by an oxide and they regenerate the initial copper.

What is the Percentage of Copper in "Copper" Coins?
Whether in the UK or in the US, the mass of the copper in a copper alloy penny can be determined. If you are in the US, just note that on the lab sheet, a penny is identified as a "1p piece." The penny is dissolved by young chemists in nitric acid.

What is the Percentage of Copper in "Copper" Coins
In this titrimetric analysis worksheet, students determine how much copper is actually in a copper coin. They titrate an iodine solution make from the coin with sodium thiosulphate to determine the mass of the copper present. Students solve 10 post lab questions and write an evaluation of the lab.

TESI 04 Lesson Plan
Learners write and balance five chemcial equations which have been observed throughout the process of completing the experiment. They use vacuum filtration to recover suspeneded particals from a colloidal suspension. Students correctly identify the copper or copper minerals in a recoverd sample of copper material

Chemical Consequences of Burning Fossil Fuels
Future scientists are introduced to the chemical consequences of burning fossil fuels, learning that fossil fuel combustion leads to the formation of oxides of three nonmetals: carbon, nitrogen, and sulfur, all of which end up in the atmosphere and water.

CHM 152-Acids, Bases and Salts (Chptr. 14)
In this acids, bases and salts worksheet, students answer sixty three questions about ionization, pH, pOH, strong acids and bases, equilibrium and salts. They write formulas for acids and bases, they identify conjugate acids and bases and they find pH and pOH of solutions.

The Chemical Detective
In this chemical detectives worksheet, students perform 6 tests on various unknown solutions including a test for chloride ion, sulphate ions, carbonate ions, iron (III) ions, iron (II) ions and copper (II) ions. Students record their tests, take down observations and make an inference about each result.

Acid Base Problems
The pH, concentrations, and formulas are needed to complete this worksheet. Pupils should be able to list physical and chemical properties and then provide definitions and equations for common bases and their reactions. Space is provided for equations of dissociation and for the graphs for the titrations given.

Physical and Chemical Changes
Students observe examples of physical changes that can take place between the three states of matter and develop common sense and intuition in distinguishing between chemical and physical changes. They observe diagrams on the board from which they identify the one that is not a physical change and explain the difference between a physical and chemical change.

Exploring the Physical and Chemical Properties of Polymers
Students identify the physical and chemical properties and explore the differences. In physical and chemical property lesson plan students test polymers for the differences between the physical and chemical properties, record their observations and orally, and in writing communicate their results.
