This Grade 3 hard worksheet pushes students to trace inherited traits across generations under NGSS 3-LS3. Four multiple-choice questions look at sibling rabbits, trained dogs, curly hair families, and tomato plants, then five fill-ins review species, variation, offspring, generations, and learned behavior. Students must read each example carefully, use evidence, and choose between inherited, learned, and environmental explanations using clear Grade 3 language.

Inherited Traits and Learned Behaviors
Part A: Multiple Choice
Circle the best answer for each question.
1. Two sibling rabbits from the same parents have different fur colors. What science idea does this best show?
A) Variation within a species
B) Only learned behavior
C) All traits are the same
D) Only environmental change
2. A young dog learns to sit after its owner practices with it every day. What kind of behavior is this?
A) Inherited trait
B) Learned behavior
C) Variation in species
D) Parent trait only
3. Grandma, Mom, and a child all have curly hair. What does this pattern across generations best show?
A) A learned behavior
B) An environmental effect
C) An inherited trait
D) A new species forming
4. A tomato plant grown in rich soil with lots of water grows bigger than one in poor, dry soil. What best explains the difference?
A) Learned behavior
B) Environmental influence on a trait
C) A completely inherited trait
D) Variation only
Part B: Fill in the Blank
Write the correct answer on each line.
1. A group of living things that can reproduce with each other is called a species.
2. Differences between members of the same species are called variation.
3. A child of parents is called an offspring.
4. Grandparent, parent, and child together represent three different generations of a family.
5. A skill gained from practice, like reading, is a learned behavior.
