Mira, Dev and their teacher Ms Sen compare a small sunny planter with a larger shaded planter inside their enclosed school rooftop garden.

The school’s rooftop garden had a mystery. One planter looked dry; another still held dark, damp soil. Mira and Dev stood inside the enclosed garden with their teacher, Ms Sen. “The dry one gets more sun,” Dev noticed. “Then sunshine must be the whole answer!” Mira nearly agreed. But their gardening notebook showed that the two planters had not been cared for in exactly the same way. Before changing the watering plan, they needed a better question.

Talk together: Separate an observation from an explanation. What did Dev see, and what did he assume?

The friends examine different soil mixtures and unequal watering measures, discovering why their first comparison was unfair.

They compared the clues. The sunny planter was smaller and held a sandier soil mixture. Yesterday it had also received less water. “We changed several variables,” Mira said. “A variable is something that can differ.” Their first comparison could not show which difference mattered most. Ms Sen brought four matching empty pots. “Can we test just the effect of shade on soil-water loss?” Dev opened a fresh notebook page. This time, they would plan before guessing.

Talk together: Name three differences that made their first comparison unfair. Which one will their new test deliberately change?

With Ms Sen supervising, Mira and Dev prepare four matching pots of soil and measure equal water for a controlled comparison.

With Ms Sen, they put equal masses of the same mixed soil into four identical pots with sealed bases. Each received the same measured amount of water. No plants went into these test pots: they were investigating soil drying, while the growing plants kept receiving normal care. They weighed every pot and recorded its starting mass. Two would stay sunny; two would sit beneath a small, open-sided shade screen. Two pots in each group could reveal an odd result.

Talk together: Explain why the soil, pots and starting water must match. What extra information can a second pot in each group provide?
