About this worksheet

What students practice

Students use field-journal observations and graph data as evidence about plant traits.
Students explain how a difference in wind exposure can be related to differences in plant traits.
Students identify fair-test conditions and limits of evidence about environmental effects.

How to use

Read the field journal together, then have students use the graph and recorded observations to support careful claims about wind exposure and plant traits.

Curriculum

NGSS standard covered

Wind Notes from the River Dam Viewpoint

Use field-journal evidence to explain how wind exposure can affect plant traits.

Read the field journal

Read Nia's field journal from the river dam viewpoint. Use the journal and graph to answer the questions.

Nia's River Dam Journal

Nia studied young bean plants at a viewpoint above a river dam. She placed six matching plants in pots. Three pots stood on the open side of the viewpoint, where moving air often reached the plants. Three pots stood behind a solid screen, where the plants were sheltered from most of the moving air.

Nia used the same soil, pot size, amount of water, and number of hours of sunlight for both groups. On Day 1, each plant was 10 centimeters tall and had seven upright leaves. The stems stood straight.

On Day 3, Nia wrote that the open-side stems leaned more than the sheltered stems. On Day 5, the open-side plants had leaves with small tears, while the sheltered plants had fewer torn leaves. She measured the average stem lean and counted torn leaves for each group.

The open-side plants had an average stem lean of 18 degrees on Day 5. The sheltered plants had an average stem lean of 4 degrees. Nia recorded the number of torn leaves in the graph. The plants had the same starting measurements, but they did not have the same Day 5 observations.
