Introduction
Today, we will be investigating biomimetics, robotics and gravity. The purpose of this engineering challenge is to inspire you to explore how we can USE gravity (a possible source of green energy) to move a simple walking robot and how we can DEFY gravity to build an arch. We also challenge you to explore these two engineering problems as a scientist would. What does this mean?
Scientific exploration is different than just playing around because it asks you to think about HOW you investigate. This means you need to do your investigation by observing what happens when you change a variable you have carefully chosen. This helps you to understand WHY something happens. Scientific exploration also means that you record WHAT you see or measure and that you record WHY you think it happens. The Young Scientist Journal that you are holding will help to guide your investigation and give you a place to record your observations, measurements and conclusions.
