Daisy loved the rain. As she listened to the pitter-patter against her window, she often wondered how the water got all the way up into the sky. “Are there invisible ladders for the droplets?” she whispered to herself.

One morning, she decided to turn her kitchen table into a miniature laboratory. Her fluffy cat, Barnaby, perched on the edge of the chair, watching closely as Daisy carefully filled a clear glass bowl with warm water.

Daisy stretched a piece of clear plastic wrap tightly over the top of the bowl. From the freezer, she took a few cold ice cubes and placed them right in the center of the plastic. Now, she had to be very patient.

Before long, the warm water inside the bowl began to turn into misty steam. When the steam hit the cold plastic under the ice, it turned into tiny droplets, just like clouds in the sky. “Look, Barnaby!” Daisy whispered. “It's my very own little rainstorm!”

She immediately opened her bright yellow science notebook. With her favorite pencils, she carefully sketched how the water rose as steam and then gathered under the plastic wrap. She wanted to remember every single detail.

The next day, Daisy took her notebook to school. During recess, she showed her drawings to her friend Leo. “The sun warms the water in the oceans,” she explained, “and it turns into invisible vapor that travels up to the sky.”

Leo adjusted his glasses and studied the diagram. “That’s amazing, Daisy,” he said thoughtfully. “But does the cycle ever stop? What happens if the sky runs out of water one day?”

Just then, Maya joined them. She looked at the cloud Daisy had drawn and asked another question. “What if the air is extra cold?” Maya wondered. “Does the vapor turn into snow instead of rain?”

The questions from her friends sparked new ideas in Daisy’s mind. She realized that science didn't end with just one experiment. Every answer seemed to grow into a brand-new mystery to solve. She added their questions to her notebook like little stars.

That evening, Daisy stepped out onto the balcony with Barnaby. She hugged her notebook to her chest and looked up at the vast, darkening sky. To Daisy, the clouds weren't just fluffy white shapes anymore; the whole sky was one giant, beautiful laboratory.
