New Data About Plant Growth
Let’s continue thinking about what might be going on with the soil in the restoration project area by comparing soil that is rich in nutrients and soil that does not have as many nutrients.
Plant Growth in Different Soils
Question 7

The pictures below show the scientist’s data. Type in the chart - what do you notice about the plant grown in nutrient-rich soil compared to the plant grown in nutrient-poor soil?
The plants in the nutrient rich soil ______________________
The plants in the nutrient poor soil ______________________
This picture shows photos of plants that were grown without enough nutrients.

Investigating Plant Growth in the Simulation
Now that we have seen the difference in plant growth between nutrient-rich soil and nutrient-poor soil, let’s investigate further to figure outHow do nutrients in the soil help plants grow?
Directions: How Do Nutrients in the Soil Help Plants Grow?
Change the ecosystem so the nutrients disappear from the soil. (Think what adds nutrients to the soil…)
Observe what happens to the plants in the ecosystem.
Answer the questions below, based on your observations.
Question 10
10.
How did you remove nutrients from the soil in the ecosystem?
Question 11
11.
Observe what happens to the plants when there are no nutrients. What did you observe?
Question 12
12.
Add the nutrients back into the soil. What do you observe about the plants?
Question 13
13.
What do you notice about the food matter that plants make when they are healthy? How is that different from when they are unhealthy?
Question 14

B) Into the soil
C) Into their own bodies
D) Into the bodies of other organisms
You are doing an experiment for science class to test the argument that plants need sunlight to grow. You have two identical plants, identical pots, the same amount of soil, and the same amount of water.
Which of the following set-ups would help test your question?
A) Place both plants in the sun.
B) Place one plant in the dark, one in the sun, then switch them after two weeks.
C) Place one plant in the dark, one in the sun.

Question 9

What is different about the body matter of a plant growing in nutrient-rich soil compared to a plant growing in nutrient-poor soil?
The plant growing in nutrient rich soil _____________
Explain what’s happening in Picture A compared to Picture B. Why is that happening?
In picture A, plants ______________ because ______________
In picture B, plants ______________ because ______________
What do nutrients do for plants?
A) Plants need them to make food and body matter
B) They do nothing, plants don’t need them
C) Plants need them to make more food and body matter faster
How do nutrients affect an ecosystem?
A) They have no effect on ecosystems.
B) They make the soil healthier, which creates healthier plants, which creates healthier animals.
