SAASTE Technology/Modules/Structures Grade 8

Frame Structures SITUATION: You have received a Hi-Fi / play station. It is a very expensive piece of equipment and needs to be kept safe. You will need to use the knowledge and skills of this module to address this situation. Your solution must be a frame structures that includes at least three structural elements you have learnt. (E.g. columns, beams, arches, buttress, struts, stays, guys and ties) Structures have FIVE BASIC FORCES that acts on it. Structural elements are used to strengthen structures that are subjected to various forces that act on it Activity 1: Research Task Look at pamphlets, magazines, furniture stores and various structures to get information. Cut out or Draw pictures showing how structures are strengthen by various structural elements. Identify and Show at least 2 structural elements in each picture / drawing. Make an A4 poster of these structural elements with labels and present it to the class. Place this research task in your portfolio under the section: Investigate. Assessment: RESEARCH Activity 2: Investigating rigidity Investigate whether the following shapes are rigid or non-rigid. Image:SA_NC_Saaste_Modules_23.png Use the following as a guide in your investigation. Use sticky tape and strips of cardboard to make the shapes shown above. Use a small amount of force to check whether the shape is rigid or not. Make the non-rigid shape rigid with extra strip/s of cardboard. Record your results on the table below: +Draw on each shape how you made it rigid.40px40px40px40pxWhat are the smallest numbers of extra strips you need to do so?What shape is repeated? What can you deduce from this investigation? Find pictures or draw sketches that demonstrate this type of strengthening in the real world. Paste it on an A4 page and put it together with the above activity under INVESTIGATE. Activity 3: Practical task - Group work (4 learners per group) Collect the following materials at home or at school. Cardboard Egg containers Straws Corks Plastic bottles, lids, plastic containers Nails Polystyrene Glue String Wood Wool Skewers Wire Sucker Ə Design and make any article using at least 3 of the above materials and include at least 3 structural elements in the one design. Identify a problem, need or opportunity and write a brief State 2 specifications for the product. State the tools and materials list Evaluate the product against the specifications and whether the structure is stable/ rigid when a force is applied to it. Suggest one improvement to the product. You must also comment on the impact of your product on the environment.

People would have fast and easy technical things like:•Mobile cellphone •Microwave And other technical things.In grade 8 we learn that frame structures have many sides.
