Teacher Resources for Instructional Planning


HS, Physical Science Std 5: Describe physical and chemical changes in terms of endothermic and exothermic processes. • Describe the composition and classification of matter. • Explain phase changes in terms of kinetic theory • Differentiate between physical and chemical properties/changes. • Classify matter according to characteristic properties.

Lesson Plans: Chemical Change and Physical Change To investigate some characteristic of chemical change. Coke Soda, Hot VS. Cold Students will learn a physical chemical reaction in two bottled coke soda, hot vs. cold pop. Students will measure the beginning and the ending of bubbles. Chemical Changes By doing the following demonstrations, students will gain an understanding of how chemical reactions produce new substances. Physical and Chemical Changes In Matter The student will be able to distinguish between a chemical and physical change in matter. Physical and Chemical Changes To study the difference between a physical and a chemical change. The Chemistry of Fire and Other Oxidation Reactions Discover that oxidation is an exothermic reaction. Measuring the Heat Energy of a Chemical Change To study the Law of Conservation of Energy. Secret Message Using the characteristic of a chemical reaction to write a secret letter. Activation Energy The student will define the terms endothermic, exothermic, and activation energy. Heat of Reaction - Hess's Law In this experiment, you will measure and compare the quantity of heat involved in three reactions. These heats of reaction will be measured using a styrofoam calorimeter. 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. Basic Endothermic / Exothermic Lab As a "Matter" of Fact Students describe how matter changes from one state to another. Change Of State A series of exercises to teach the states of matter. Characteristics of Matter The objectives of this lesson are for primary and intermediate graders to examine the relationships among gravity, weight, and mass, the metric measurement of distance and volume, and density and its application to physical properties. It's a Gas! To compare some properties of different gases. Learning About Matter And Energy Students will learn and understand physical properties of matter and energy. Students will discover that some things float, some things dissolve in water. They will be able to discuss that energy can be changed from one form to another.

Resources: Elements: Excellent information about the elements on the periodic table of elements. "Happy Atoms." Good Tutorial Chem4kids Great tutorials and activities. Tom Stretton's Chemistry Pages Great tutorials and practice problems The Periodic Table of Comic Books Associates each element with a comic reference - fun Interactive Periodic Table Created by an eighth-grade student!
