What Plants Need

Grade 2 - Science - Building Confidence

Worksheet 1

  1. Read the plant setup: Plant B has light, air, and soil but gets no water. What need is missing?

  2. Which plant part is connected to this job: takes in air?

    A plant diagram has one part label hidden.A diagram of a plant with leader lines to 4 parts. 1 label is shown as empty boxes to be filled in.flowerstemroots

  3. Which observation is evidence that the plant needed sunlight?

  4. Which fair test checks whether a plant needs sunlight?

  5. The graph compares plants with water and plants missing water. What claim does the evidence support?

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, 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. Challenge versions include air, space, and stronger evidence statements. 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, light, air, and space as plant needs
  • Connect plant parts with plant needs
  • Use evidence from a plant investigation
  • Choose a fair test for plant growth

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.
