Where do inventions come from?
1. Inventions come from problems to be solved.
What problems did the inventors face?(expressions:People wanted something..../People had a hard time... They wished...)
People wanted something to communicate over long distances quickly. They had a hard time sending messages far away. They wished for a faster way to talk to others.
How did they solve the problem?(expressions:The answer was to.../...decided to invent a ... It was able to...)
The answer was to invent the telephone. Alexander Graham Bell decided to invent a device that could carry voices through wires. It was able to let people speak to each other even when far apart.
2. Inventions come from curiosity.
Describe the importance of curiosity for inventions by giving some examples of inventors.
Curiosity drives inventors to explore and create. For example, Benjamin Franklin was curious about lightning, so he flew a kite in a storm to study electricity. Marie Curie wondered about invisible rays, which led her to discover radium.
What is the importance of the invention?
3. Figure out the functions and importance of inventions. (expressions:It is able to work with..../Once it senses...., it starts.../It will be able to...)
The light bulb is able to work with electricity to provide light at night. Once it senses the switch is turned on, it starts shining. It will be able to help people work and study even after sunset.
What qualities do inventors have?
4. Summarize the qualifies of inventors. (expressions: ..., a ...scientist/inventor, was curious about... He/She spent years studying ... Finally, he/she...)
Creativity:They imagine new solutions (like Post-it Notes from weak glue). Persistence: Thomas Edison spent years testing materials for the light bulb. Curiosity: Zhang Heng studied earthquakes to invent the first detector.
