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.
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.
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)

Could technology help us tackle the obesity crisis?
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?
Worldwide obesity has nearly tripled since 1975, yet obesity is preventable.
Most of the world's population live in countries where overweight and obesity kills more people than underweight.
In 2016, more than 1.9 billion adults, 18 years and over, were overweight. 38 million children under the age of 5 were overweight or obese in 2019.
What's a possible solution?
Other solutions to explore -social media, history of technology,wearable technologies, human enhancement (bionic) gamification,relationships, and healthy communities.
What can we do?
Research the history of technology and sport. Design programmes, circuits that includes technology and social human elements to create interactive challenges (treasure hunt) or track fitness and health (pedometer).
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.
