A civil engineer designs and builds things like bridges, dams, roads, and buildings, airports, tunnels, and systems for when you flush the toilet.
It’s actually one of the oldest branches of engineering. When people first starting living in permanent settlements like cities, they started to shape their environment to what they needed.
Early engineers build things like walls, roads, and bridges. They also dug wells for water and made irrigation ditches and trenches. As the settlements grew into larger towns and cities, people needed clean water, ways to get rid of waste, and streets and roads that everyone could use. That’s where civil engineering comes in.
For today's class, all you need is a sheet of paper, tape, and a heavy book. You can also use newspaper and an egg if you want to do the second engineering challenge!
