PaginePaginepagineapp.comRuby wanted to build a volcano for the science fair.
She and Dad made a mountain from clay and painted it brown.
The night before the fair, Ruby tested it. She poured vinegar onto baking soda, but nothing happened!
Ruby felt like crying. "My volcano is broken," she said.
Dad looked closely. "I think the baking soda is old," he said.
They bought a fresh box in the morning.
At the fair, Ruby's volcano bubbled and fizzed over the top.
Everyone clapped, and Ruby learned to always test her supplies.
Number the events in order (1–4).
