. How did he discover it?
• What was new for you in the text?
• What would you like to learn more?

The text is called "Mistakes that worked" because it discusses various inventions and discoveries that were made by accident or as a result of mistakes. It highlights how some of the greatest inventions in history were not intentionally planned, but rather happened by chance or through trial and error.

The discoverer of penicillin is Sir Alexander Fleming. He discovered it by accident in 1928 while studying bacteria. Fleming had left a petri dish containing Staphylococcus bacteria uncovered, and when he returned, he noticed that mold had grown on it. He observed that the bacteria near the mold had been killed, leading him to discover the antibacterial properties of the mold, which he named penicillin.

In the text, one new thing mentioned is the discovery of the microwave oven. It explains how Percy Spencer, an engineer at Raytheon, accidentally discovered that the microwaves from a magnetron had melted a candy bar in his pocket. This led to the development of the first commercial microwave oven.

Another new thing mentioned is the discovery of Teflon. It explains how Roy Plunkett, a chemist, was trying to create a new type of refrigerant, but instead discovered a slippery polymer substance, which later became known as Teflon.

In regards to what was new for the reader, it would depend on the individual student's prior knowledge and reading comprehension. Some students may find the entire text to be new information, while others may have known about some of the inventions mentioned.

As for what the reader would like to learn more about, again, it would be subjective to each student's interests. They may want to delve deeper into the specifics of penicillin or explore other accidental discoveries throughout history.

Therefore, the text is called "Mistakes that worked" because it focuses on inventions and discoveries that were the result of mistakes or accidents. It highlights how some of the greatest inventions in history were not intentionally planned but instead happened by chance or through trial and error. Sir Alexander Fleming is the discoverer of penicillin, which he stumbled upon while studying bacteria. He noticed that mold had grown on a petri dish and observed that the bacteria near the mold had been killed, leading to the discovery of penicillin. The text discusses the accidental discovery of the microwave oven by Percy Spencer and the accidental discovery of Teflon by Roy Plunkett. It may contain new information for the reader depending on their prior knowledge, and they may want to learn more about specific inventions or accidental discoveries.
