Plant Growth Data

Students in Ms. Adelman's 4th grade class were studying what makes plants grow.

They learned that plants take energy from the sun, carbon dioxide from the atmosphere, and water from the soil to

grow.

They did a science experiment to see how changing the amount of water a plant receives will affect its growth.

Using five of the same type of plant, they observed the growth of the plants over 2 weeks.

Each plant was assigned a different amount of water to receive each day.

Students measured the total growth at the end of the first week and again at the end of the second week.

They recorded their findings in the graph shown.

1. Which plant showed the greatest growth over the two-week period?

• Plant 2

• Plant 5

• Plant 4

• Plant 1

4. 5. Based on the information from the graphs of both Week 1 and Week 2, if the students continue the experiment until Week 3, Plant 5 is most likely to:

• grow taller than plant 4

• show no growth in week 3

• grow 5 cm in week 3

• show more growth than any other plant
