Science Performance
Grade- 2
Topic – Plants
Title:
How Plants Grow
NGSS Performance Expectation(s) and Learning Target(s):
2-LS2-1 Plan and conduct an investigation to determine if plants need sunlight and water to grow.
Lesson Performance Expectations including Standards: (LESSON)
Carry out investigations to gather and analyze data to provide evidence to determine if plants need sunlight and
water to grow.
Student Science Performance
A. Gathering:

Students will plan and conduct experiments with plant seeds to determine if plants need water and
sunlight to grow.
o Test item 1: seed/plant with sunlight and water
o Test item 2: seed/plant with sunlight; no water
o Test item 3: seed/plant with water; no sunlight
o Test item 4: seed/plant with no water, no sunlight
Record observations to changes over time.

B. Reasoning:
 Analyze observations to determine what elements led to optimum plant growth.
C. Communicating:
 Students construct a written explanation to communicate the results of their experiments that
determined if plants needed sunlight and water to grow.
Assessment of Student Learning (Formative and Summative):

Students will use initial predictions and observations to construct an explanation using evidence to
support their conclusion of determining if plants need sunlight and water to grow.
Critical Vocabulary:
Growth, sunlight, water
Science Essentials (Student Performance Expectations From Appendix C, D, E)
Science Practices
Carrying out Investigations

Conduct investigations and record observations to gather data to serve
as the basis for evidence.
Analyzing & Interpreting Data

Make observations of changes of the seeds and plants.
Constructing Explanations

Use evidence to construct explanations.

Events have causes that generate observable patterns.

Plants depend on water and light to grow.

Allow for partner work and group discussions


Students can measure plant growth.
Students can conduct repeat experiments using different types of
plants or seeds.
