The night before

This is an original short story. The characters and events are invented. At seven-thirty on Wednesday night, Noor's volcano sat on a tray on the kitchen table. It was made of clay around a plastic bottle, painted brown, with orange lava painted down the sides. The Grade 4 science fair was the next morning. Her poster was already finished, and under the heading Results she had written in big red letters: HUGE ERUPTION! The lava shoots out of the top!

She had not actually tested it yet. Noor had watched videos of baking-soda volcanoes foaming over like a pot of boiling pasta, and she was sure hers would be the biggest in Grade 4. She spooned baking soda into the bottle hidden inside the mountain, poured in a cup of vinegar with red food colouring and stepped back. There was a small hiss. A little pink foam rose to the top, made one tired bubble and slid back down.[1]

Again, and again

"It's just warming up," said her older brother, Sami, from the couch. Noor rinsed the bottle and tried again with twice as much baking soda. Fizz, bubble, nothing. She added a squirt of dish soap, because one video said soap makes more foam. The foam was a little thicker, but it still did not pour over the top. She poked the opening wider with a pencil, in case the clay was blocking it. The mountain gave the same small burp.

By nine o'clock, the vinegar bottle was empty, her hands were sticky and her poster still said HUGE ERUPTION! Sami came to look. "Just leave the poster," he said. "Nobody's going to make you do it in the gym. Or print a picture from one of those videos." Noor looked at the bright red letters. It would be easy. Nobody would know.[1]

The notebook

When Noor went to pack her science notebook, it slipped out of her hand and fell open on the table. Earlier that week, Mr. Okafor had asked everyone to draw a table with three columns: What I changed, What I saw, What I think. Without really meaning to, Noor had filled in a row after every try. Trial 1: normal amounts, small fizz. Trial 2: double baking soda, small fizz. Trial 3: dish soap, thicker foam, no eruption. Trial 4: bigger hole, small fizz.

She read the table twice. It was the only thing on the kitchen table that told the truth. The poster said what she had wanted to happen. The notebook said what had actually happened. Noor imagined standing in the gym beside a picture of somebody else's volcano while a visitor asked, "How did you make it so big?" She would have to keep making things up all morning. She picked up a black marker and, before she could change her mind, drew a line through HUGE ERUPTION![1]

What really happened

Under the crossed-out words, she taped a fresh strip of paper and wrote a new heading: What Really Happened. She copied her four trials from the notebook. Then she added a box called My Guesses. Maybe the baking soda was old. Maybe I did not use enough of it for that much vinegar. Maybe I changed too many things too fast, so I cannot tell which one mattered. It was almost ten when she went to bed, and the volcano still had not erupted.

In the gym the next morning, the volcano at the next table foamed all the way onto the floor, and a group of Grade 2 students cheered. Noor's stomach felt tight. Then a Grade 5 student stopped at her poster and read the crossed-out words out loud. "Why didn't it work?" she asked. Noor took a breath and pointed to her table. "I don't know yet," she said. "But here's everything I tried, and here's what I think."[1]

One change at a time

Mr. Okafor read her poster for a long time. "If you tested it again, what would you do differently?" he asked. Noor did not even have to think. "Change only one thing each time," she said. "Last night I kept changing everything because I was in a hurry." Daniel, the boy with the overflowing volcano, had been listening. "I don't really know why mine worked," he admitted. "We just kept adding stuff until it did."

When Noor got home that afternoon, she did not throw the volcano away. She opened her notebook and wrote a new row: Trial 5: same as Trial 1, but with a brand-new box of baking soda. Change nothing else. She underlined it twice. On Wednesday night, she had wanted a volcano that looked amazing. Now she wanted to know why hers had not worked, and she was going to find out one change at a time.[1]

Fast lesson

Use these checks before you answer the practice questions.

Draw the story map first

Before the questions, sketch five boxes: characters, setting, problem, events and solution. Add one sticky note for each of Noor's trials under events, then move them into order.

Two kinds of solution

Compare with 'Two Ideas, One Poster', where the poster finally works. Here the volcano never erupts. Ask your child whether a story's problem can be solved even when the experiment still fails.

Hoped vs happened

Connect to real school work: write two columns, What I hoped and What actually happened, for a recent project, game or recipe. Talk about what the second column teaches that the first cannot.

Common mistakes

Saying the story has no solution because the volcano never erupts.

Why this fails: The problem is what Noor will report. It is solved when she tells the truth and plans a fair test.

Calling Daniel's eruption the turning point.

Why this fails: Noor had already crossed out her false result the night before. The turning point is the notebook falling open.

Giving a summary when asked for a theme.

Why this fails: A theme is a general lesson. If the answer needs the characters' names, it is probably a summary.

Problem1. What is the main problem in this story?
Show answer and explanation

Answer: Noor's volcano will not erupt the night before the fair, but her poster already says it did.. The volcano only fizzes, yet the poster already says HUGE ERUPTION!, so Noor must decide what to report. Noor works alone, Sami never breaks the volcano, and the overflowing volcano belongs to Daniel.

Setting2. Where and when does most of the problem take place?
Show answer and explanation

Answer: In Noor's kitchen on the night before the science fair. All four trials and Noor's decision happen at the kitchen table on Wednesday night. The gym is where the story ends, the classroom is only mentioned as where she learned the table, and she never goes to a store.

Sequence3. Which list shows Noor's three extra attempts in the order she tried them?
Show answer and explanation

Answer: Double baking soda → dish soap → a bigger hole. Trials 2, 3 and 4 are double baking soda, dish soap, then a bigger hole. The other orders mix them up, and the brand-new box is only a plan for Trial 5.

Practice answer key

  1. 1. HUGE ERUPTION! The lava shoots out of the top!
    It is in the first paragraph, written in big red letters.
  2. 2. A plastic bottle.
    The first paragraph says the clay is built around a plastic bottle.
  3. 3. One video said soap makes more foam.
    The reason is given in 'Again, and again'.
  4. 4. What I changed, What I saw, What I think.

  6. 6. She will use a brand-new box of baking soda and change nothing else.
    It is the new row in the last paragraph.
  7. 7. She was so sure the volcano would work, and so focused on it looking impressive, that she skipped the actual test.
    She expected hers to be 'the biggest in Grade 4'.
  8. 8. Disappointment; the volcano seems weak and worn out instead of exciting.
    Authors pick describing words to show a mood.
  9. 9. It is late, the vinegar is gone, and she could look successful without anyone knowing.
    The story says, 'It would be easy. Nobody would know.'
  10. 10. She knows it is the right thing to do but still feels tempted, so she acts before the temptation wins.
    The phrase shows she is still struggling inside.
  11. 11. She was nervous that people would compare her small fizz with Daniel's big eruption.
    The detail comes right after the Grade 2 students cheer for the other volcano.
  12. 12. She had already noticed in her guesses that she changed too many things at once, so she knew what to do differently.
    Her My Guesses box from the night before prepared her.
  13. 13. Characters: Noor, Sami, Mr. Okafor, Daniel, a Grade 5 student. Setting: Noor's kitchen on Wednesday night, then the school gym the next day. Problem: the volcano will not erupt and the poster already says it did. Solution: Noor reports what really happened and plans a fairer test.
    A story map shows how the parts of a story connect.
  14. 14. Noor adds dish soap → the notebook falls open → Noor crosses out HUGE ERUPTION! → the Grade 5 student asks why it did not work → Noor plans Trial 5.
    The attempts lead to the turning point, and the decision leads to the ending.
  15. 15. Daniel's volcano shows a big eruption, but he cannot explain why it worked. Noor's poster has no eruption, but it shows every trial and her thinking.
    A strong answer names one strength and one gap for each.
  16. 16. No. The volcano never erupts. Her problem is solved when she reports honestly and finds a better way to keep testing.
    In some stories the solution is a change in the character, not a perfect result.
  17. 17. Example: Being honest about a disappointing result helps you learn what to try next.
    A theme without names can apply to anyone.

Compare with a model response

The main character is Noor, a Grade 4 student, and the story happens in her kitchen the night before the science fair and then in the school gym. Her problem is that her baking-soda volcano only fizzes, but her poster already says HUGE ERUPTION! She tries double the baking soda, then dish soap, then a bigger hole, and each time it only gives a small burp. The turning point is when her notebook falls open and she sees that her trial table tells what really happened while the poster tells only what she wanted. She crosses out the false result and writes What Really Happened, with her trials and guesses. At the start Noor cares most about having the biggest volcano, but at the end she wants to know why hers did not work and plans to change one thing at a time. The theme is that being honest about a disappointing result helps you learn and keep going.

Original fiction. All characters, the school, the trial table and events are invented. The story does not claim to explain why the volcano fizzled; Noor's guesses are labelled as guesses. The source supports the story-map strategy used in the practice, not the story's events.
