Course Overview

This fun and informative Experience will explore how we use technology to measure time to the millisecond in competitive sports, and how we can measure reaction times. Faster reaction times are better, right? We will begin using coding (the visual programming language called Scratch) to create a fun reaction timer game.

Led by our sports-loving, tech-savvy, super charismatic expert, this interactive session will discuss the concept of timing in sports, as a measure of performance in competitive events like running and swimming. What modern technology is used to measure for how fast we run or how quickly a car can race? What are the advantages of using that technology over human observation? Are lasers really better than humans? We will look at instant replay tools and sensors, timing gadgets and how technologies such as RFID chips help capture timings automatically.

We will introduce Scratch and make a simple ball heading game, as an introduction to measuring and improving our own reaction times.

This Experience is perfect for competitive kids who are interested in learning how technology and sports can work together to help humans run, jump and fly further and faster than ever before. No previous knowledge of coding is required. 

FireTech Experiences are a new series of short, high interest, fun and engaging tech demonstrations and talks. These are delivered in webinar style, with the main presenter demonstrating a new interesting aspect of technology and learning, and taking questions from attendees. 

What your child will learn

  • Introduction to Scratch programming, a visual block-based programming language that is easy to use
