Term 2 Topic 3 Combining Materials IntroductionMaterials can be processed to make new materials or products such as:Mixing and setting (e.g. plaster of Paris or polyfilla and water to make plaster).Mixing and setting (e.g. sand, gravel, cement and water to make concrete).Mixing and cooking (e.g. making dough).Mixing and cooling (e.g. jelly powder and water to make jelly).Mixing and drying/firing (e.g. wet clay and straw to make clay bricks).The properties of the new materials/products may be different to the those of the original materials.Teacher Input 1Before the lesson starts, the teacher will need to:Watch the video clip on Making Glue (link provided below).Set up all ingredients.Prepare a poster board with heading: PROCESSED MATERIALS.Prepare pictures of processed materials for learners to glue to the poster board (e.g. jelly, cake, clay bowl, etc.).Greet learners.Make the glue in front of them, explaining each step.Learner Activity 1Allow learners to use the glue to paste pictures of processed materials on the poster board.Ask learners to look at each picture and try to list what was combined to make each one.Teacher Input 2Show Presentation 1.Show Video Clip 1 (1:38 minutes).This video shows us how to make new material from existing material. It shows us how to make glue that is non-toxic & eco-friendly.Show Video Clip 2 (4:43 minutes).The video shows how easy it is to make your own shower gel or liquid soap from a bar of soap.Show Video Clip 3 (7:02 minutes) .The video shows the steps taken to make a clay pot.Learner Activity 2This activity is designed to give learners the opportunity to show that they can work in a group, give instructions, and demonstrate that they understand how products are processed.Divide learners into groups of 4.Each group must choose one process – Making Jelly; Making Glue; Making a Clay Pot; Making Cement; etc. – and prepare an oral presentation on this process.Groups must have clear instructions and pictures in their presentations (drawn or printed).Learners will find guidelines for this task from THUNDERBOLT KIDS pg 76 - 193 .Groups will then present their demonstrations to the class.After each demonstration, learners will create a flow chart on how the processed material was made (example from THUNDERBOLT KIDS pg 173).Teacher Input 3Give feedback on the Group oral presentations.Hand out Worksheet A and ask learners to complete it.Hand out Worksheet B.Using the example of pineapple jelly, explain to learners how to fill in the worksheet.Learners must fill in answers using their vocabulary list.Revision Activity 1Learners complete Quiz 1.Revision Activity 2Learners complete Quiz 2 in class or as homework.Additional Resources: Video LinksMaking pottery clay - https://www.youtube.com/watch?v=aYCA7rmX_4YMixtures and solutions - https://www.youtube.com/watch?v=e-2EoyDYamg By Administrator|2015-07-16T12:33:49+02:00June 17th, 2015|0 Comments Share This Story, Choose Your Platform! facebooktwitterlinkedinredditwhatsapptumblrpinterestvkEmail About the Author: Administrator Leave A Comment Cancel replyYou must be logged in to post a comment.
