The school science fair was in two weeks. Leila, Adam, and Hamza decided to work together. They wanted to make a model of a volcano that could really erupt.
They spent the weekend building the volcano with paper and clay. Adam made the shape, Leila painted it to look like real rock, and Hamza read about the chemical reaction they needed.
"We need baking soda and vinegar," said Hamza, reading from a book. "When we mix them, they create a gas called carbon dioxide, and it makes the liquid bubble up like lava."
On the day of the fair, they set up their volcano on the table. Many students and teachers gathered around to watch. Leila poured the baking soda inside the volcano. Then Adam slowly added the red-coloured vinegar.
Suddenly, red foam erupted from the top of the volcano! Everyone gasped and then clapped. Their teacher smiled and said, "Excellent work! You explained both the science and the art very well." They won first prize.
