Here’s another Aha Moment signpost, this time from The Watsons Go to Birmingham—1963, by Christopher Paul Curtis. In this passage, Kenny is on the school bus with his friend, Rufus and his younger brother Cody. Rufus and Cody are very poor, and a mean kid, Larry decides to make fun of the clothes Rufus and Cody wear. After a rude comment from Larry, everyone on the school bus, including Kenny, laughs. Read the passage below and highlight the portion that shows you that Kenny is having an aha moment. Then
answer the anchor question: How might this change things?

Maybe it was because everybody else was laughing, maybe it was because Cody had such a strange look on his face while he peeked at his underpants, maybe it was because I was glad that Larry hadn’t jumped on me, but whatever the reason was I cracked up too.

Rufus shot a look at me. His face never changed but I knew right away I’d done something wrong. I tried to squeeze the rest of my laugh down.

21 balloons is the story of professor william sherman's travels.

in 1883, he set off from san francisco for a balloon ride over the pacific and was found a month later floating with 21 balloons in the atlantic ocean. this seemed an astounding feat and everyone wanted to know what had happened.    

professor sherman was loyal, however, and said he would tell his tale first to the western american explorers club in san francisco, of which he was a member. this built up suspense for several chapters before he began to tell of the wonders of his adventures and the amazing island of krakatoa, an island which had just been blown up by a volcano.  

the residents of krakatoa are all millionaires who live under a "gourmet government" of their own devising. we get to see all the incredible adventures that creative people with unlimited resources would create according to the author.

ian mortimer in his book "the time traveller's guide to elizabethan england" uses a narrative in his style, which successfully conveys a clear description of the life in england in the 16th century. he writes in second person, which makes it comfortable to reader and easy to understand, he captures the readers attention with views of the landscape, the streets, the people including rich and poor. he also depicts some cultural traits from how people behave, eat or what they wear. his descriptions range from the social, economical, the political power to the examples of the life of common people. it could be tell that this book is about social history rather than a   novel.
