Special Guest Blog - Science and Computational Thinking (part 2)

With nearly 3 billion people already facing water scarcity, farmers look to both tech and tradition for ways to grow more food with less of an increasingly strained resource

CT Progress

In authentic contexts and taking account of end-users, students decompose problems into step-by-step instructions to create algorithms for computer programs.

They use logical thinking to predict the behaviour of the programs, and they understand that there can be more than one algorithm for the same problem.

Outcome 3

They develop and debug simple programs that use inputs, outputs, sequence, and iteration (repeating part of the algorithm with a loop). They understand that digital devices store data using just two states represented by binary digits (bits)

Student Speak

  • I can look at a problem and figure out the steps to solve it. I can use a solution and code algorithms for digital device programs.

  • I can predict what my program will do based on the code that it receives.

  • I understand that there can be different algorithms that solve the same problem.

  • In my code I will use inputs, outputs, sequences, and repeat loops (iterations).

  • I can debug my program so that it runs efficiently.

  • I know that digital devices use bits to store data

 

What's the problem here?

Today some 2.8 billion people face insufficient supplies of fresh water, and according to the United Nations that number is set to increate to half the world's population by 2030. The UN Food and Agriculture (FAO) reports that 40% of the world's food depends on irrigation, which accounts for almost 70% of fresh water used.

It makes sense then that farmers are turning to new and old technology in an attempt to manage their water.

 

What's a possible solution?

Other issues to explore - environmental, political, economic, cultural, technological as well as implications for Artificial Intelligence in industry.

What can we do?

Research issues around food production, water use, reuse waste and use technological systems to create a solution to a localised problem.

Use simple programming (sequence, inputs, outputs) to create a digitised solution. Use a design thinking process to create a prototype, test, debug, evaluate, share. Reimagine.
