Term 2, Week 1

Mental Edge

This morning we discussed 'futurism' and 'being a futurist'. We then watched a clip from 1974 where Arthur C Clark was discussing his ideas behind 2001: A Space Odyssey.

It appears that he is predicting the internet and PC's. The ODC students then put their 'Thinking like a Futurist' hat on to predict where they think technology will be in 38 years time. Here are some of their ideas.

* There will be voiced controlled computers that have their own voice boxes. The internet will continue to improve: faster, more information and more readily available to everyone.
* Pantry Pads. A pantry pad shows what food you have in your pantry. You tap it and it will bring food to you. It will put food away for you and bring you what ever you tap on it.
* I think 'Willy Wonka' type technologies will available.Food will be transported through televisions, especially fast food, that will be the food of choice in the future. I also think food will also be in a pill.
* Computers will continue to get smaller and they will be completely voiced activated, but it will only recognise your voice for security reasons.
* Technologies will  will be developed and available to the people faster and will upgrades to new technologies will happen automatically.
* Human body transplants will continue to evolve to the point where there will be human brain transplants.
*Holograms is a wasted technology that I think will evolve more in the future. People will use holograms for work conferences that they are unable to attend.
* You will be able to be transported physically into a game using the technologies that were used in the Hydron Collider.
* You will be able to visit virtual worlds using glasses and move and interact within them as your own physical being.

Concept

 Oobleck is one of those things you just have to see (and touch) to understand. Sometimes it acts like a solid, sometimes it acts like a liquid. It all depends on how much pressure you put on it.Today we used it to test out some of our debatable truths about CHANGE.

All CHANGE has a cause and effect
CHANGE can be influenced
The speed and impact of CHANGE can vary (a new generalisation)
CHANGE can be positive, negative or neutral.

 Oobleck is a material that is also known as a dilatant. A dilatant is a material that gets thicker with an increase of pressure. Oobleck is a liquid until pressure is applied to it and then it solidifies. It seems to defy Newton’s Third Law of Motion that states that every action will have an equal and opposite reaction. Here is a great way to test this … take two pie pans, fill one with water and one with oobleck, take both outside and slap them with an open hand. The water will splash while the oobleck stays put on the bottom of the pan. Water is a Newtonian fluid because it obeys Newton’s Laws of Motion. Oobleck is a non-Newtonian fluid because it defies Newton’s Third Law of Motion. 

Once we had finished making and playing with oobleck, we linked our experience back to the debatable truths. 

Have a go at making it at home and see if you can work out how the debatable truths fit in with its non-Newtonian form.

What you need:
  • Cornflour
  • Water
  • Mixing container
What to do:
  1. Place 1.5cups of cornstarch in the container.
  2. Add 1 cup of water and stir well.
  3. Add more water or cornstarch until you get a mixture which “tears” when you quickly scrape your finger through it and then “melts” back together again.
Squeeze it! ... Smoosh it! ... Scoop it! ... Pinch it!

 Some other fun things to observe about OOBLECK:
  • Oobleck is a solid and a liquid at the same time. 
  • If you make a ball and throw it up in the air, it loses shape and becomes flat in the air. 
  • Oobleck can be molded in a container and when taken out does not keep shape. 
  • If you fill a balloon with 0obleck, the air presses or forces the Oobleck back out. 
  • When you leave Oobleck in the sun, the color evaporates, it turns hard like cement on the top and like jelly on the bottom. When heated this also happens and it is sticky. 
  • Oobleck does not bounce.

  1. Enjoyed reading the post, a lot of great ideas from the children about future technologies.The interview with Mr Clarke was great.
