"Little Nobel" PPT courseware 2

Nobel is a famous Swedish inventor. He has liked to do small experiments since he was a child, and he is a child who loves to use his brain.

Once, little Nobel went to the street to buy salt. On the way back, he and some friends started playing in the sand. A friend accidentally broke the salt bag and spilled the salt. He was so anxious that he didn't know what to do. Little Nobel thought for a while and said, "It doesn't matter, I have a way." He put away the dirty salt.

When he got home, little Nobel poured the dirty salt into the water without haste, and the salt dissolved in the water. Then he filtered the brine through a gauze screen, leaving the sand behind. Finally, he put the filtered salt water into the pot and boiled it. After the water evaporated, white salt appeared at the bottom of the pot. The friends said in admiration: "Nobel, you are really good!"

For the experiment, pile up the salt, spread it, take over the pot and cook it.

Think about it:

1. How does salt stain?

2. What did the friends and Nobel do after the salt was sprinkled?

The first step: Little Nobel poured the dirty salt into the water calmly, and the salt dissolved in the water.

Step 2: He uses a gauze to filter the brine, leaving the sand on the gauze.

Step 3: He put the filtered salt water in the pot and boiled it.
