| Volunteer Valerie Goodmanson, with two rounds of work in Tanzania to her credit, continues her work on behalf of Mwangaza as she oversees the new On-Line Partnership for Secondary Teachers in the U.S. and Tanzania. Mwangaza volunteers are beginning the new year with new colleagues across the globe. U.S. volunteer educators in the areas of math, science, biology, chemistry, physics, and English are sharing concepts, ideas, and educational resources with partner teachers in Tanzania. Although access to the Internet is still limited in most ELCT secondary schools, many secondary teachers are able to connect to the Internet at cyber cafes in towns near their schools. This access, combined with the new computer technology and Internet access at the Mwangaza Centre in Arusha, has enabled us to begin the next phase of our On-Line Partnership. U.S. and Tanzanian teachers have been paired, and, using e-mail as their communications vehicle, international, professional dialogues are taking place as Tanzanians and Americans share teaching tecniq1ues, strategies, and resources, culminating in the completion of lesson plans. Ultimately, Mwangaza will have an On-Line repository of lesson plans that can be accessed by teachers throughout Tanzania. After a successful first year, new and veteran Mwangaza On-Line volunteers are busy once again making connections with teachers throughout Tanzania. The challenges of an international, electronic venture such as this are many, but the enthusiasm of these U.S. and Tanzanian teachers, built upon a common goal of educating children, will see us through. To learn more about this opportunity to volunteer your expertise in the areas of secondary education listed above, please contact Mwangaza Volunteer Valerie Goodmanson at vagoodmanson@rochester.k12.mn. us |

| Habari Emmanuel, Kazi, kazi shambani na darasani. Pole lakini nitajaribu kutoa msada kidogo ! Here are two demonstration ideas that I used to introduce the idea of carbon chemistry…to show that carbon is in so many things around us that don’t appear “black.” #1 Destructive Distillation of Wood (Heating in the Absence or Reduction of O2) • Place some wood splints or sticks in the bottom of a large test tube with a one hole stopper with a glass elbow tube. • Incline the test tube with a clamp and ring stand. Heat the bottom of the tube with a Bunsen burner flame (hold the burner by hand so that you can control the heating). • As the various volatiles leave the tube, you will be able to ignite them at the end of the glass elbow. Liquids may condense near the top of the tube and run back down. The incline should slow this process. • Let the tube cool and then knock out the black carbon residue. • You can then hold the carbon in a flame and show how it burns like charcoal…because it is! • You have just made makaa!...just like folds do in the bush by burning and then smoldering tree stuff! (But your test tube and stopper will be pretty messy!) • I did this demo using cigarettes to help show all of the nasties that are involved in smoking. #2 The last of what I have to offer today applies to making organic ball-and-stick models. Following is a recipe for model-making material. Your students may be very familiar with making mtungi and will know where to find good clay for permanent ball-and–stick models. I suggest tooth picks and bendable wire for the stick bonds. A reusable “clay” here in the U.S., called Play Dough, can be rolled into little balls of differing sizes to represent C, H, O, N and others. Food colors can be added to help to keep them apart. I have just made the recipe below this morning and even though there are references to refrigerators, just cooling should do the trick. Traditional Play Dough [uses cream of tartar – potassium hydrogen tartrate –KC4H506] 1 cup flour 1 cup warm water 2 teaspoons cream of tartar 1 teaspoon oil ¼ cup salt Food coloring Mix all ingredients, adding food coloring last. Stir over medium heat until smooth. Remove from pan and knead until blended smooth. Place in plastic bag or airtight container when cooled. It will last for a long time. (I found cream of tartar in a grocery store spice section.) I have also used paper clips to teach isomer naming…give them a small number of clips (3) and ask increase the number of clips. Do you teach the IUPAC naming system? Basi for now…naomba radthi if this is too simple for your needs or if you already have these ideas!! Fafiki yako, Neil |
| Hope that you are doing fine sir. How are you and your family and all that you are engaged in? I am so fine and the shamba la bwana business has started and the responsibility for this year is quite much because I teach the Form I through 4 Chemistry and the practical part of it in addition to the Second year Open University course. Then there are my other personal life responsibilities. All in all, I believe that through the Lord’s help I will be able to run all with the maximum efficiency and success. Due to the maximum teaching load I have, I am facing the minimum time to visit the Internet café to write to you, but I will try to visit at least once each weekend. For now I have two classes (the second and the fourth level) that need serious attention for the best achievement in their national examinations, as well as my learning the efficiency of the current or new teaching methods we are learning at MWANGAZA. For the fourth level I have started with the topics that will be applicable in their practical examinations and thereafter Organic Chemistry will follow. The only problem I face in teaching Organic Chemistry for the low level is for me to find the best and simplest way for introducing the topic so as to minimize cramming since I have discovered that most of the students need to memorize. May I therefore ask that if you won’t mind, then help me in the form of the lesson plan as well as the simple teaching aids that will be useful for students to build the concept instead of memorizing. Besides that, I am also facing the shortage of the organic models for teaching Organic Chemistry. Therefore, if possible might you find some of the Organic Chemistry teaching models so as to simplify the job? With thanks in advance, may you please receive my sincere greetings from Mwangaza’s Internet Café, Bye for now, Your friend, Emmanuel Laban |
