LI: to learn about bombs and structures
This week we had a visitor named Mr Ching. He taught us about Dumb Bombs and Smart Bombs. Dumb Bombs are like grenades. The Dumb Bombs go where you aim them. When you shoot them you have no control. Smart Bombs are bombs that you can control when you launch them.
After that we watched a video of the results of missiles, and shock waves. Shock waves are the air that are really strong and can destroy you. We also learned something about a sonic boom. A sonic boom is when the air compresses together and releases and makes a big clap, or boom sound.
After that we first got into groups of five and had to make a structure that is strong enough to stop the structure. Our materials were paper, tape, scissors, and straws. We had to make a structure to be strong enough to protect a helicopter. When we finished we had to test our structures. We simulated a shock wave using boards.
