Fractals is the Science of Surprises; it teaches us to expect the unexpected. It deals with nonlinear things that are impossible to predict or control like turbulence, the stock market or our brains. Chaos Theory helps us to capture the complex and infinite mathematical patterns in the world around us; trees, snowflakes, mountains, rivers and organs like our lungs and brains. With the help of Maths and Computational Thinking we can get an insight and some wisdom about the fractal nature of our world and make sense of it. These 4 challenges will give you an opportunity to explore and discover the fractals and recursive designs with your students.
