G9 Science – Engineering Project – Reflect and Share

How successful we were:

  • We were able to complete the project only needing to work outside of class once.
  • We were not able to consistently power our LED.
  • The turbine does not spin at a constant speed and often does not spin at all because the water cannot handle the torque we put on the turbine through gears.

How the turbine works:

  • The turbine is attached to a shaft with a gear on the other side that leads into a wooden box where there is a smaller gear attached to another shaft that leads to a dynamo. The dynamo is then attached to an LED. When water turns the turbine, the gears turn and power the dynamo, lighting up the LED.

Reflection

  • The decision of making a gearbox to increase the amount of electricity generated per rotation was not very good because the increased torque created caused the turbine to not be able to turn under the water at ISB.
    • We think that our turbine would be able to consistently generate electricity if there was a higher water pressure.
  • Remodeling the turbine we made to make some structures longer would allow our turbine to catch more water and thus allowing our turbine to turn would be a good improvement.

Impact

  • Our turbine could be extremely useful if we made some minor improvements and if it is paired with a fountain to pour the water again at the top.
  • The turbine could be placed in a natural stream and generate energy through environmentally friendly sources.

G9 Science – Engineering Project – Create and Improve

February 21st

  • Gathered needed materials such as wood, shafts, and gears.
  • We were able to build a small-scale model that worked via a hand-crank

February 23rd

  • Took apart our model and began building our large model
  • Began building our gearbox

February 27th

  • Built housing for our dynamo and attached the LED
  • Created additional supports for our turbine
  • Created a 3D model of our turbine and printed
    • The dimensions of the model were not thick enough to print

March 1st

  • Revised 3D model and reprinted
    • The model had too many supports

  • Remade 3D model and printed

  • Created a backup turbine in case the model will not print well

Feedback

Jayden:

  • Liked the initial idea of creating a water turbine to create electrical energy
  • Could have made the device simpler by removing gears from our design

  2. Finish decorating

G9 Science – Engineering Project – Define and Inquire

Potential ideas:

  • Wind-up toy 
      • This video shows an extremely straightforward design for a wind-up car, but if I choose to follow this design, I will employ gears to create a more complicated wind-up toy.  
    • Summary: The toy will be easy to use, similar to that of traditional wind-up toys.  
    • Energy: The winding mechanism will transfer elastic potential energy into kinetic energy.  
    • Challenge: ★☆☆☆☆
  • Water turbine 
    • Pros: Many resources online to teach me how to build and design the machine.  
    • Cons: This requires some knowledge of 3D printing, and I need to learn how circuits work.  
    • https://www.youtube.com/watch?v=zqdaWFHn1Tc 
      • The video shows a medium-scale design of a water turbine, but if I choose to make a device similar to this, I will probably scale it down.  
    • Summary: The water turbine will be able to light up a light bulb or an LED while it is being spun.  
    • Energy: The water turbine will use the falling water as gravitational energy to turn the turbine, turning the generator with kinetic energy that creates electrical energy.  
    • Challenge: ★★★★☆
  • Drum 
    • Pros: Building should be simple and easy to make.  
    • Cons: I have limited knowledge of what the design of the device should be like.  
    • The motor has multiple ‘sticks’ attached, and sticks hit a balloon spread across a cup.  
    • Summary: The spinning motor will generate sound by hitting the ‘drum’. 
    • Energy: The kinetic energy of the motor will allow the ‘sticks’ to hit the ‘drum’ creating sound energy.  
    • Challenge: ★★☆☆☆

¿Lo que está en Melbourne? (Los mejores y los peores) 

 

31 octubre, 2022  

Por Bowen Ke  

Melbourne es una ciudad al lado del mar. Hay muchas playas y muchos espacios verdes. En mi opinión, Melbourne es una de las mejores ciudades en el mundo para visitar. Pero, la ciudad tiene muchos aspectos malos. Por ejemplo, Melbourne tiene muchas personas que sin casas. La ciudad es muy buena para las personas que gustan viajar.  

LOS PROS 

Las Playas 

Melbourne tiene muchas playas. Una playa en la izquierda, una playa en el derecho, playas en todas las direcciones. Si vas a la playa, trae un amigo o amiga. ¡Es muy divertido! Pero, las playas tienes muchas personas y es muy ruidoso. 

Las Comunidades 

La ciudad de Melbourne es muy internacional. La gente es muy bienvenida a los extranjeros. La ciudad tiene más de cuatro millones inmigrantes. Además, la ciudad es muy ecológico. Por ejemplo, muchas compañías usen paquetes ecológicos, y tiene muchos espacios verdes. La ciudad tiene muchos parques para perros y personas.  

La Cocina 

En mi opinión, los mejores lugares para comer son los cafés. Todos los cafés son locales, y la comida todos son saludables. Otra comida famosa en Melbourne es el pescado. La mayoría de las veces, el pescado se pescar el mundo. Todos los pescados son frescos. Hay un café en la mayoría de las calles. Las personas venden los cafés por solo cinco dólares. 

El Entretenimiento 

Hay muchos parques de atracciones. Los parques son muy famosos en Australia. Son un poco viejos, pero los parques son muy divertidos. También, in Melbourne el arte en las calles son muy hermosas. Tiene calles que solo tiene arte, con Banksy y otros artistas famosos.  

LAS CONTRAS 

La Educación 

La educación en Melbourne es muy lenta. En mis cuatro años viviendo en la ciudad, yo no aprendí nada. En mi opinión, los profesores en Melbourne son un poco perezosos.  

El Costo de Vida 

Las casas son muy caras en este momento, y la comida son caros también. Si vas al supermercado, usar más de cincuenta dólares australianos. Pero, la cualidad es muy bueno, y son muy deliciosos.  

La Transportación pública 

La transportación pública no está muy eficiente y crea mucha contaminación. El tráfico es muy malo y los autobuses son muy lentos. El sistema de transporte público tiene bastante personas.  

La Gente 

Hay mucha gente en la ciudad, especialmente en el centro. La mayoría de la gente es muy sociable y simpático, pero algunas personas son muy molestas y groseros. Otro problema es la gente sin casas.  

El Clima 

 

El clima en Melbourne es extremo, a veces, el clima cambia muy rápido. En un momento, hace sol y triente minutos después, está lloviendo. El tiempo es un poco frío en el invierno, pero es bastante calor en verano. 

Welcome to Your New Blog!

When you blog you create posts and posts are categorised according to your subject. Some categories have already been set up for you. If you need more categories you can add them as needed. It’s important that your posts have the following:

  • An engaging title – this should not include the name of the subject since this is referenced in the category.
  • Body – this is where you share your learning. This can include text, images, embedded videos from Dragons’ Tube or elsewhere. You should always consider how your post looks to your audience. Is it engaging? Do they want to keep reading?
  • Category – select one that has been set for you or add a new category. Posts can have more than one category e.g. Humanities and Myself as a Learner
