Grade 3 Science Sheet 3 at medium level explores how the environment shapes living traits and how that differs from true inherited ones. Students complete nine fill-in items and match four examples about plant height in sunlight, tomato fruit size with water, tanning skin, chameleon color shifts, and fixed inherited eye color. Hints and explanations reinforce Grade 3 NGSS 3-LS3 vocabulary all throughout.
