Plants in Two Museum Places

Use observations to investigate sunlight and water.

Read the investigation records

The Harbor Children's Museum tested basil seedlings for a plant-care display. Read the records and use them to answer the questions.

Two Places and Two Plant Tests

Educators at a children's museum wanted to learn how a plant-care display should be set up. First, they placed three similar basil seedlings in a sunny atrium and three similar seedlings in a dim reading nook. All six seedlings began at 6 centimeters tall. Every seedling received 20 milliliters of water each day. After 10 days, the atrium seedlings were 9, 8, and 9 centimeters tall. The nook seedlings were 7, 6, and 7 centimeters tall.

Next, the educators placed six similar seedlings in the sunny atrium. Three seedlings received 15 milliliters of water each day. The other three received no added water. The seedlings began at 5 centimeters tall. After 8 days, the watered seedlings were 10, 9, and 10 centimeters tall. The seedlings with no added water were 5, 6, and 5 centimeters tall. The educators used the same kind of pot and soil for both tests.

What was the height of the tallest atrium seedling after 10 days? centimeters

Which comparison gives the best evidence about the effect of sunlight in the first test?
