Question: What color are birch tree leaves?
Claim: Birch tree leaves are green
Reasoning:
• The evidence supports my claim that leaves are green.
• Based on this evidence we know that all leaves have
organelles called chloroplast, which have a green pigment
called chlorophyll that makes the leaves appear green,
therefore since birch tree leaves have chloroplast, the
leaves are green in color.
• The leaves are green because of pigment chlorophyll.
