Essential Question:
How is science and technology changing the world? Past, present and future. Are these changes good? Why or why not?

I definitely think it have changed the world. Because past, they needed to take forever to sent a message. Present, we can sent a mail in a second! I believe in future it can be even faster.
Also in past there were to many works need to be done by humans. Present, technology took some job from humans like getting milk. In future I believe the technology is going to take over humans job.
