CHAPTER
1
Where Did the Salt Go?
It was a gloomy and chilly Saturday. Maya looked
out the window. Rain was falling hard. Water ran
down the sidewalk. It filled potholes in the street.
She wished the rain would stop. She wanted to go
outside and play.
2
Maya’s mom came into the room. “Maya, it is going to get cold
later,” she said. “The rain will turn to ice. The front walk will
be slippery. Can you go to the shed and get some sidewalk
salt? The salt will help keep the sidewalk from becoming icy
and slippery.”
Maya liked to help her parents. She put on her raincoat and
boots. Then she headed outside into the rain.
3
Maya found a bucket of sidewalk salt in the shed. She tried to
lift it, but it was too heavy.
Maya looked around. She found a paper bag with handles.
It would be easier for her to carry. She used a small shovel
to fill the bag with salt. Then she carried the bag to the front
sidewalk. She would check the weather again in a few hours.
4
Later that afternoon, Maya looked outside again. She could tell
it was getting colder. Snowflakes were mixing with the rain. It
was time to spread the salt.
But when Maya got outside, she saw that the paper bag was
very wet. It had turned to mush. The salt was almost gone,
too. Maya wondered how this could have happened!

Talk it over
Ask these as you read or afterward. Answers for the teacher are tucked under each question.
Then she headed outside into the rain. 3 Ask students the following questions: LITERAL—What do you see on the television in the background?
Answer
A weather report SUPPORT—Point out that the weather report on the television shows cold temperatures and wintry precipitation (rain or snow). INFERENTIAL—Why might someone want to know what the weather will be?
She would check the weather again in a few hours. 4 Ask students the following questions: LITERAL—What kind of container is the salt kept in?
Answer
A container that is big; a container that is plastic; a container that is deep LITERAL—What kind of container is Maya putting the salt into?
INFERENTIAL—Do you think it is a good idea to put the salt into the paper bag?
Answer
Yes, because it will hold the salt; no, because the salt came from a different kind of container
Maya wondered how this could have happened! 5 LITERAL—What happened to the paper bag?
Answer
It got wet. It got ruined. It turned to mush. SUPPORT—Point out that the water from the rain soaked through the paper bag. That got all the salt wet. When salt mixes with water, the water dissolves the salt. This is the reason there is not very much salt left. LITERAL—What made the bag turn to mush?
