Scientific Observations Quiz

A student measures the height of three sunflower plants after giving them different amounts of water. Plant X receives 1 cup, Plant Y receives 2 cups, and Plant Z receives 3 cups of water daily. After two weeks, Plant X is 10 cm tall, Plant Y is 20 cm tall, and Plant Z is 30 cm tall. What can be concluded?

• Sunflowers grow best with only 1 cup of water.

• More water helps sunflowers grow taller.

• Plant Z is shorter because it gets the most water.

• All plants grow the same regardless of water.

Students recorded the number of birds visiting three different feeders in a park. Feeder A had 15 birds, Feeder B had 25 birds, and Feeder C had 10 birds. All feeders had the same type of birdseed. What is the best conclusion?

• Feeder B attracts the most birds.

• Feeder C has the most food.

• Birds prefer feeder A’s location best.

• The type of birdseed affects the number of birds.

A class tested how different colors of light affect plant growth. Plants under red light grew 12 cm, under blue light grew 15 cm, and under green light grew 8 cm after one month. All other conditions were the same. What conclusion can be drawn?

• Plants grow best under green light.

• Blue light helps plants grow taller than red or green light.

• Red light prevents plants from growing.

• Light color does not affect plant growth.
