After a review of the electroscope and what it showed, charging by conduction and induction were introduced separately using the demonstration from the video. The science behind each method was discussed, and notes written following the tapes.

Using electroscope images demonstrate that like charges repel and unlike charges attract. Review the atomic structure, indicating that only the electrons move from object to object. A positively charged object is due to electrons being transferred, leaving a surplus of protons, and a negatively charged object is due to receiving electrons. The law of conservation of charge was defined and demonstrated with arbitrary numbers given to transfers from and to objects in contact. The electroscope was looked at and shown to just indicate charge, not the type of charge.

continuation with electrostatics and electric charges on objects

Introduction to electrostatics... The neutrality of matter, the fundamental particles of an atom, the charge on each particle and the way in which a substance becomes positive or negatively charged...
How a balloon can become charged and attract pieces of tissue to it. A video demonstrating different examples of static electrical charge was shown and discussed.

A review of the term rate as it applies to chemical reactions started the class. The collision theory of chemical reactions was briefly discussed, and the effect of temperature, as covered previously, was reinforced. The effect of concentration on rate was explained, and reinforced using a shared video which reinforced the concept by showing reactions under differing concentrations of reactants. Some of the reactions were previously done in our lab. The effect of particle size was also demonstrated in speeding up the rate of a reaction. All The factors were then outlined for her notes.

Review exothermic reactions, show examples. Define and discuss with examples endothermic reactions. Explain why the taking in of heat makes the reaction colder. Explain the term rate, and that it involves time. Discuss slow rate reactions and fast reactions, using everyday examples. Discuss factors which change the rate of reaction; temperature and concentration.

Discussion of the types of energy which are involved in chemical reactions, with the emphasis on thermal energy. The definition of exothermic reactions, along with examples of exothermic reactions performed in the lab. A video was used to show an exothermic reaction producing "elephant tooth paste". The energy graph of an exothermic reaction was drawn from information in the text.

A review of the 4 major types of chemical reactions started the class. The textbook was used to read passages defining what an ionic bond is and how ions are formed. The periodic table was used to define and explain the groups and periods of elements on the table, and the meaning of the group and period numbers. The determination of valence numbers and energy levels of specific atoms was found using these numbers. The relationship between the chemical properties of the atoms or ions and that of the compounds formed was briefly discussed, with importance placed on the fact that the properties of the compound are different from the properties of the individual elements

The 2 remaining types of chemical reactions were outlined.They were a single replacement reaction and a double replacement reaction. Examples of each were given in both word and chemical reaction form. Single replacement being A + BC = B + AC, with an example from a previous lab we performed. The double replacement was shown by the general formula AB + CD = AD + CB. A previous lab reaction was also used. Two YouTube videos were shared to show some interesting demonstrations of both types of reactions.

A formal lab write up was done for the lab given the previous day. The chemistry of the formation of iron oxide by increasing the rate of the reaction, oxidizing iron by flame. The production of oxygen and hydrogen gas, along with the testing done to show the presence of each was written up as a lab experiment, and the reactions explained.
