How to Make Polymer Jewelry

article-new_ehow_images_a07_cq_gr_homemade-polymer-jewelry-800x800

Polymer clay can be baked in a conventional oven instead of a kiln. This is because polymer clay hardens at a lower temperature than earthen clays, making it an ideal type of clay for children to work with. You can make a variety of different projects using polymer clay, including colorful and artistic jewelry that can be given as handmade gifts to friends and family members.

Things You Will Need:

 –       Polymer Clay

–       Clay Knife

–       Toothpick

 

Instructions:

  • 1 Roll 8 oz. of polymer clay into a 1/2-inch-thick snake. Polymer clay comes in many different colors, or you can select white polymer clay that can be painted after it is baked.
  • 2 Cut the clay snake into 1/2-inch-long pieces using a clay knife.
  • 3 Roll each piece of clay around in your hands to soften it. Mold the clay into the shape you want for each bead.
  • 4 Insert a toothpick into the middle of each bead, then pull out the toothpick to create the bead hole.
  • 5 Preheat the oven to 200 degrees. Bake the beads on a cookie sheet for 10 minutes. Let the beads cool.
  • 6 Cut one 18-inch length and one 8-inch length of elastic string.
  • 7 Thread beads onto both strings, leaving open space on both ends of each string.
  • 8 Tie the ends of the long piece of string together in a knot. This will create the beaded necklace.
  • 9 Tie the ends of the short piece of string together in a knot. This will make the beaded bracelet.

 

Tips & Warnings

  • Use acrylic paint to paint or decorate polymer clay beads after they have been baked.

Frog Dissection Experiment Follow-Up

Biology class is always fun especially when you learn to dissect animals. As a student, this is one of the most exciting experiments they can experience in their life. As a teacher, this will always be fun to teach the kids and make them understand more of the anatomy of humans and animals. Today, we dissected frogs to further understand how magical the body works.

Most of the students who participated got a little scared with the frogs. I know it’s a little cruel to ‘murder’ them but we will never learn how to dissect properly if we will not do it. Also, it’s quite difficult to find formalin preserved animals here in Cambodia, unlike in the Philippines where we can purchase them from specialized shops who caters for needs like this. I also thought of giving them chloroform as a general anesthetic, but I backed out. Jumping frogs make the experiment more exciting, right?

In summary, my students had a wonderful time doing the dissection. Just look how happy Sovannareth as he cut the frog open 🙂

G6 Unit Project: Build a Solar Oven

Product: Solar Oven

Subject: A device that can boil water using energy from the Sun

Research and Take Notes

Gather information – Look up “solar oven” on the Internet to find out how such devices work. You may find different types of solar ovens, but all will have common features.

Take notes – Take notes or draw sketches of ideas that you want to incorporate into your design. Look for the simplest design that will be easy for you to build and will meet your requirements.

Determine your materials – List all of the materials you will need to build your oven. Choose materials that are inexpensive and easy to find. Solar ovens often use materials that can be found in your home or school, such as cardboard boxes and aluminum foil.

Develop Your Design

Apply your knowledge – You know that dark colored surfaces get warm in sunlight and that shiny surfaces reflect sunlight. Solar ovens uses shiny panels to reflect sunlight into the cooking area, which is usually painted black.

Consider the constraints – Design a plan that you can build within the time constraints for the project and that uses simple materials. You will also need a workspace and an outdoor, sunlit location where you can set up your oven and leave it for periods of time.

Draw a sketch – Make a labeled sketch of your design. List any additional tools and materials that you will need to build the oven.

Build and Test Your Solar Oven

Follow safety procedures – Use caution when cutting cardboard with a knife or other cutting tool. Be sure to use gloves or oven mitts when handling the container of water.

Build and test your oven – Gather your materials and build your oven. Place it in a sunny outdoor spot with the cooking area facing the Sun. The oven should begin to reach 100 degrees Celsius within 20 minutes or so.

Modify your design – If the water does not boil, reposition the oven so more light is reflected in the cooking area. Think of ways to increase the efficiency of your oven. Make design changes to raise the temperature of teh oven more quickly.

Write up your lab report –  Complete your sketches, notes, lists, and explanations about your oven. Write a paragraph or draw a detailed diagram that describes how the oven works. Hand in your lab report.

Demonstrate your oven – Prepare demonstration of your solar oven for teh class. If your demonstration must take place outdoors, point out the parts  of the oven and explain how it works. Compare your design with those of others with the same project. If your oven can be used to heat pizza or another food, you may want to share some with the class.

Deadline: 26th of October 2012

G8 Unit Project: Medicines Around You

Product: Oral report on a medicinal plant with samples

Subject: Local plants with medicinal uses

Research and Take Notes

Research – Search the Internet, using the key words “medicinal plants” and the name of the region you live in, to identify possible plants to research. You might also use an encyclopedia to research the healing customs of the native peoples in your area.

Take notes – Paraphrase or write note in your own words from the sources you consult. Be specific about what illnesses the plant is used to treat as well as how the medicine is prepared. Find out what is the important compound or active ingredient  in the medicine. If you find a picture of the plant, make a copy or sketch of it. Be sure to not the title, author, publisher, and location of each source.

Collect Samples

Find samples –  If you have access to a plant conservatory or nature museum, seek the aid of an employee to help you find a sample of the plant. Visit a forest a preserve only if you are accompanied by a forest ranger or other adult. If you cannot find any samples of the plant, find as many pictures or make as many sketches as you can of the plant.

Develop Your Report

Look at your information –  Read again all the information you have collected. Decide what information you wish to include in your report.

Plan your visuals – Decide how you will use your visuals. Will you direct attention to any particular parts of the plant? Will you demonstrate how the plant is prepared for use as a medicine? Be sure your visuals can provide the information you wish them to show.

Write a script – Write a script for your report. Read it aloud and revise any parts that sound rough.

Practice Your Report

Practice – Practice your report several times before delivering it. Use a tape recorder so you can listen to how you sound.

Present – You will present your report to the class on Tuesday, 2nd of October 2012.
