About this worksheet

Plant growth is easy for children to observe, but explaining it with evidence takes practice. Second graders may say a plant needs soil because they see soil in a pot, while missing the tested variables of water and light. They may also name plant parts without connecting those parts to needs. This worksheet asks students to read short investigation setups, identify the missing need, connect roots, stems, and leaves to jobs, read growth graphs, and choose fair tests that compare one changed condition at a time.

Diagram labels are hidden when the label is the answer. Support versions use familiar water and sunlight examples and one-step graph reading. Challenge versions ask children to choose what to change and what to keep the same, predict what happens next, and read a graph with three plants. Encourage your child to ask what changed, what stayed the same, and what observation proves the plant need.

What your child will learn

Identify water, sunlight, and room to grow as plant needs
Connect plant parts with their jobs
Use evidence from a plant investigation
Choose a fair test for plant growth

NGSS standard: 2-LS2-1

Worked example

If one bean plant gets water and another does not, weaker growth in the dry plant is evidence that water matters.

Common mistake

Naming something near the plant instead of using the investigation evidence.

Helpful hint

Look for the condition that is missing or changed.
