STEM Project: Tools and Machines in Primary School Education

This homework assignment explores STEM concepts through the lens of tools and machines suitable for primary school education. The document begins by examining various tools, including levers, sliders, and pulleys, explaining their functions and applications, and providing visual aids. It then delves into the workings of a grass-cutting machine, highlighting the integration of these tools within a practical context. The assignment also touches upon the STEM program and its significance in fostering science and technology development within schools, with a focus on project-based learning activities like growing crystal trees and candy science experiments. The assignment concludes with a list of references to support the information presented.

PHOTOS OF TOOLS
Levers
It is the tool that is helpful in moving one object from one place to another. The centre point is
called fulcrum , if the person sit far away from the fulcrum then more force will be apply. More
force is applied by the users then more force will be produced at the initial point thus, tool will
perform its work to carry the object.
Sliders
1

It is helpful in giving strength to different tools and hold them at the same place. It is used to
produce flat surface and contour as well. That works in a direction so that movement between
two tools can be done easily and both attached tools can perform easily.
Cams or pulleys
It is used in transforming rotary motion that helps in delivering pulses of power to steam
hammer. It is the wheel that make it easy to lift things. While using this tool individual does not
have to put too much force as it rotate the rope or connector and pull the objects. It has two equal
arms, this wheel has rimmed edges that gives support to rope. By using this tool individual can
life a object by using half force.
Machine used by all these three tools

Grass cutting is the machine which is used to cut grass. In this machine, 270 individual
parts are included in which Cams or pulleys, Sliders and Levers are included. Outside of grass
cutting machine there is revolving blades are placed that supports in cutting grass surface. Height
of the machine is adjustable due to presence of bolt (Grass cutting machine, 2018.). Cams give
support in delivering pulses of power, sliders help in holding and leavers support in placing the
rough material from one place to another. Cams retain at the cutting head assembly that gives
strength to blades so that grass can be cut easily. Lever is the important mechanical tool in the
grass cutting machine which gives support to the centre and in less forced initial balder can
perform their work and can life the objectives in half force (Grass cutting machine, 2018.).
STEM
STEM is the program which includes science, technology, engineering and mathematics.
This is used by the schools to contribute in science and technology development.
PBL STEAM activities for toddlers and preschoolers can be beneficial for the school
students. Growing a crystal tree is the activity that can be included in the school by this way
learners get to know about building a cardboard tree. Furthermore, candy science experiments
are another activity that can be included under this. All these learning activities will enahnce
knowledge of students in the primary education (17 Examples of STEM Project Based Learning
Activities, 2018).
