1-LS3-1
The standard
Make observations to construct an evidence-based account that young plants and animals are like, but not exactly like, their parents.
Next Generation Science Standards
What this standard means
Students need to observe young plants or animals and compare them with their parents. They should notice shared traits, like leaf shape, fur color, body shape, or markings, and also notice differences, like size, shade, or small pattern changes.
Mastery looks like a first grader saying, with evidence, “The puppy is like the parent because they both have floppy ears, but the puppy has a smaller body.” Students often get stuck by focusing only on size, using guesses instead of observations, or saying babies are “the same” without naming traits.
Ways to teach it
- Hands-on: Give pairs parent and offspring photo cards, then have them sort matches and circle two shared traits and one difference.
- Prompt: Show a kitten and cat photo, then ask, “How are they alike, and how are they not exactly alike?”
- Quick assessment: Students draw a young plant beside a parent plant and label one same trait and one different trait.
- Real-world connection: Ask students to observe a family pet, garden plant, or grocery produce and report one trait shared with its parent kind.
