1. TEN GREAT LOW-COST TEACHING TOOLS Educational material created by Prof. Alejandra Masís Artavia‚ 2011. 2. INTRODUCTION This presentation’s aim is to provide teachers with ten low-cost teaching tools. Moreover‚ it seeks to explain the importance of using these tools and how they can be used in several ways‚ as Kevin McCaughey states in his article. 3. Tool 1: Scissors (and scratch paper)Importance of using scissors: they transform a single piece of scratch paper into 10‚ 20‚ and even 50 paper

The Effect of the Type of Building Material on the pH of the Vinegar Introduction: For this experiment‚ the town council wanted to test which building material would be the best to build statues in a zoo. The building material with the lowest pH would be the best building material because while 7 is neutral anything below 7 is considered acidic and anything higher than 7 results in a base. Precipitation of 5.5 or lower is considered acid rain. Connecticut and most of the United States have to

For instance‚ it is likely a business report‚ a daily conversation or a political issue which confuse the listener. These conversations may include words‚ phrases or terms unfamiliar to listeners. They are totally strange to them so it is such a hard job to listen when the message is full of terminology. The solution is to ask the students to practice as much as they can on these various materials. Therefore‚ they can
