Flowers for the Playhouse

Nia wants to grow marigolds beside her backyard playhouse. Before planting them outside, she and her aunt run two tests inside the playhouse. Each test lasts ten days. Every group has four young marigold plants. All plants start about the same size, with the same number of leaves. They use matching pots and the same soil.

In the sunlight test, Group L gets sunlight through a window. Group D stays in a dark, airy space. Both groups get the same measured amount of water each day. Nia's aunt checks that both spaces stay at the same temperature.

In the water test, Nia uses new plants. Groups W and N sit together in sunlight. Group W gets a measured amount of water each day. Group N gets no water during the test. Neither group gets rain.

Nia counts the leaves on every plant before and after each test. She records how many new leaves grew in each group altogether. None of the starting leaves fall off. Her graphs show only new leaves, not starting leaves.
