Grade 3 Science Sheet 4 at hard level extends the idea that many traits are inherited yet further shaped by environment and practice together. Four multiple choice questions explore bean plant height in poor soil, sibling height with good food, inherited singing voice improved by lessons, and flower color in low sunlight. Five fill-in items with careful hints reinforce the Grade 3 NGSS 3-LS3 combined-cause concept for every learner.

Inherited Traits and Learned Behaviors
Part A: Multiple Choice
Circle the best answer for each question.
1. Grade 3: A bean plant has inherited tall genes but grows short in poor soil. Which is true?
A) Height is inherited but also changed by environment.
B) Height is inherited and never changes at all.
C) Height depends only on soil, not on parents.
D) Height is a fully learned behavior from the plant.
2. Grade 3: Two siblings inherit tall genes, but one eats better and grows taller. Which statement fits?
A) Height is inherited and shaped by nutrition.
B) Height is only a learned behavior from parents.
C) Height depends only on inherited genes always.
D) Food has no effect on inherited human height.
3. Grade 3: A child inherits a good singing voice but improves greatly with lessons. Which choice is correct?
A) Singing is inherited and improved by learning.
B) Singing is only a learned behavior with no genes.
C) Singing is fully inherited and never needs practice.

Part B: Fill in the Blank
Write the correct answer on each line.
1. Plant growth patterns are inherited but can be changed by water and sunlight.
2. Human height is partly inherited from parents and partly shaped by nutrition.
3. Singing ability uses inherited voice and learned skill from practice.
4. A trait influenced by both genes and surroundings has multiple causes.
5. Good food, exercise, and care form the environment that shapes inherited traits further.
