Teacher Resources for Instructional Planning


Grade 8, Science Std 7.1: Explain the effects of temperature, concentration, surface area, and catalysts on the rate of chemical reactions. • Differentiating between endothermic and exothermic reactions.

Lesson Plans: Physical and Chemical Reactions Students examine the four ways in which a reaction can speed up (concentration, surface area, temperature, & catalysts). Chemical Reaction Rates Students learn phenomenologically some of the factors which affect the rates of chemical reactions. Reaction Rates - Catalysis, Concentration, Surface Area, and Temperature To observe factors affecting the rate of a chemical reaction. Basic Endothermic / Exothermic Lab Lab activity to demonstrate endothermic and exothermic reactions Exothermic and Endothermic Reactions Students are to observe several exothermic and endothermic reactions, determine the changes that take place in a chemical reaction, and to observe how fast a reaction is taking place and what factors influence a chemical reaction.

Resources: Chemical Bonding Good explanations and examples of chemical bonding Chem4kids Great tutorials and activities. Chemistry Index Lots of ideas from SMILE Classic chemistry experiments 100 activities
