Wow it works | MOE Singapore

moe singapore

The “wow it works” program has a close relevancy to the syllabus  dictated by MOE Singapore . We will use the “walkalong glider” as an example how this project can be fitted into MOE Singapore  requirements as “Inquiry based education” for kids .

MOE Singapore | Science knowledge , understanding and application

The central or focus is actually science , in this case , the basic is knowledge is about Bernoulli’s principle . This can be easily demonstrated using the aircraft wing design , where the top of the  wing , due to air flow will cause lower pressure compared to the bottom wing and as a result a “lift” is created .

Kids can take any pictures available on the web and trace out the shape or design . Then use the traced out design to  cut out the paper thin foam . See the diagram below

  • Trace out a image or picture from the web.
  • Then transfer the image to the paper thin foam
  • Cut out the foam to get the shape of the original image . This is a glider of a flying fish . To see the link of the flying fish glider , click the link [flying fish glider]

Now kids not only learn about Bernoulli’s principle , they get a chance to try it themselves to see if Bernoulli’s principle really works . Kids get a chance to design their very own traced out wing from the web , apply it onto a thin foam to make their very own glider and see if it works .If their design did not work , why ? If their design works , can it be further improved ? We can have a little competition to see who can maintain the longest flight duration using their glider design

Kids will learn very quickly that if the ailerons of the wing is not in proper position , the glider may not glide well . So is the center of mass or gravity of the glider . So this is in alignment to  MOE Singapore in regards to science knowledge , understanding and its  application .

MOE Singapore | Science as an Inquiry

Once kids get a chance to design and fly their own glider , kids can actually explore other possibilities .

Science as an inquiry | Man made

Let’s start with the man made wing design of aircraft . We can get kids to compare the various wing design of commercial aircraft such as the  Boeing 747 and Concord , then compare them with fighter planes wing design  .

  • Which design will fly or glide better ?
  • Why does fighter planes have such wing designs ?
  • What about the future aircraft wing designs ? How will they look like ? Why ?

Science as an inquiry | Animals that fly

Kids can also explore the wing designs of animals such as flying foxes and birds .

  • What do they have in common ?
  • What are their differences ?
  • How does the differences help them in flight and also in landing ?

Science as an inquiry | the world of insects

Next possibility is the insect world .The insect world in a very interesting and exciting world especially how they fly . Scientists today are studying the insect flight mechanism to understand them better  to design better  robots and drones

  • Examine the wing design of insects such as the dragonflies ,  butterflies and ants
  • Which wing design offer better flight stability ? Why ?
  • Note the resemblance and differences of the front and hind wings . Why ?
  • Insects normally have 2 pair of wings, eventhough some may have only reduced to just 1 pair .What are they ?
  • There is also a new discovery of insects having 3 pair of wings . What are they ?
  • Test out the frontal wing if this alone can maintain flight ? If it can , what is the purpose of the hind wings ?
  • There are insects that made use of the hind wings to fly ? Why ?
  • inquiry based educationCompare the wings of butterflies and note their similarities and differences ?
  • What other purpose do they serve ?

inquiry based education

Science as an inquiry | Wing construction

There is a lot of things that we can learn from the remarkable world around us . Nature is so wonderful that there is so much to learn . We can get kids to look into the construction of wings of insects to see how they are able to have a strong and sturdy structure and yet light enough to maintain flight . Why some butterflies fold up their wings while other lay flat ?

MOE Singapore | Systems

In the “walkalong glider” project , there is a system that one can consider from MOE Singapore stand point . In the construction and building of the glider , there is a manufacturing system . There is

  • Choice of material type (paper , foam , etc)
  • Different design parameters (dimension , weight , thickness , design , etc)  of each wing design
  • The cutting process
  • The folding process
  • The testing process.
  • The quality check process

MOE Singapore | In Summary

The wow it works program fit MOE Singapore syllabus and curriculum reasonably well . Equipped with just Bernoulli’s principle , the wow it works program opens up a lot of other opportunities for kids to explore and to experience what works and what did not , through actual hands on . Building models of actual wings of a plane , or wings of animals or insects allow kids to explore and to compare similarities and differences in the design and construction and more importantly why . It gets kids to think , to investigate , to explore , to evaluate and to try . This is what we think is needed of our kids in the future . So get them prepared for this challenge , in alignment with MOE Singapore  !!
