Question

title: effect of light color on plant growth
name: date: class period:
i. purpose / question
what question is this lab trying to answer?
write in a complete sentence:
ii. background information
use the space below to summarize what you know about:

• how light affects photosynthesis
• why plants might grow differently under various wavelengths

write 3–5 sentences: because they use specific pigments and photoreceptors that are sensitive to different parts of the spectrum.
iii. hypothesis: make a prediction using: \if…, then…, because…\

iv. independent variable (what i change):
dependent variable (what i measure):
controlled variables (kept the same): (write at least 4)

1. 3.
2. 4.

v. materials

• virtual lab: plant growth under colored light filters - pencil
• data table (provided) - calculator
• graph paper or digital graphing tool - chromebook / computer access

vi. procedure

1. open the plant growth virtual lab.
2. select the plant type (spinach, radish, or lettuce).
3. choose a light filter color.
4. run the simulation and record the average height.
5. repeat steps for all five light colors: red, orange, green, blue, violet.
6. repeat the data collection for all three plant types.
7. enter all measurements into the data table.
8. create a graph showing plant height vs light color
9. answer the analysis and conclusion questions.

Explanation:

The lab is about the effect of light color on plant growth, which relates to photosynthesis and plant biology. The subfield of Biology (under Natural Science) is most appropriate as it deals with plant life processes, photosynthesis, and how environmental factors (light color) affect plant growth.

Answer:

Natural Science - Biology
