QUESTION 1a) Grade: 7
b) Theoretical background of the project to your learners
School children were hugely affected by Covid 19 pandemic during the 2020 academic year. Many
stayed at home and were hugely affected in one way or another. One of the big problems which the
children faced was that their play time was reduced or did not happen at all. This have impacted
negatively on the learners as a teacher I need to discover how learners can benefit from
mechanical systems and control as one of the topics I need to cover. Learners will be expected to
investigate the use of levers where they will be required to design the first class lever.
c) The first step of the technological process for the project
To analyse the problem, need and want. Designing of first class lever using accessible material
d) Problem that must be solved
• Is to design the and make a first class lever that will be made using the simple material
• The material must be easier to find as some learners won’t be able to afford any material
that needs to be bought
• Learners must keep the first class lever simple
Gather information about the problem, need or want
• The learners do not understand the mechanical advantage
• Learners may not know where to place the fulcrum and how the effort is affected
• Learners may not know the simple, and accessible material that they can use
Analyse the problem, need or want
• Learners must be taught what a fulcrum is. The fulcrum is the point where the lever turns
• The learners must be given practical example of the real world situations to be easier for
them to understand what is needed on this project
