Grade 3 Science Sheet 4 at medium level focuses on identifying trait patterns across parents and offspring. Learners fill in nine sentences and match four parent pairs to possible child traits, exploring brown and blue eyes, tall pea plants, black and yellow lab puppies, and curly or straight hair. Grade 3 hints and clear why notes support the variation, generation, and species vocabulary throughout practice.

Inherited Traits and Learned Behaviors
Part A: Fill in the Blank
Write the missing word or number on each line.
1. Mom has brown eyes and Dad has blue eyes; a child may have either color.
2. Offspring receive inherited traits from both mother and father parents.
3. When traits vary across siblings, scientists call this inherited variation.
4. Puppies in one litter can have different coat colors inherited from each parent.
5. A new generation of plants or animals is called offspring or the next generation.
6. Dogs are one species with strong variation in size, color, and ear shape.
7. If both parent rabbits have black fur, offspring most often inherit black fur.
8. Tall pea plants crossed with short ones can produce different sizes in offspring.
9. Inherited traits move from parent to offspring through seeds, eggs, or birth.
Part B: Matching
Match each item on the left to the correct answer on the right.
1. Match each item to its correct answer.
