Read Sofia’s account: She watches hen Penny and five chicks. Similarities—Evidence 1: all have feathers, two legs, two wings, beak, claws. Evidence 2: all scratch, peck, flap, and roost. Evidence 3: all make chicken sounds (clucks/chirps). Evidence 4: all eat grains, insects, and greens. Differences—Evidence 1: chicks have many feather colors (brown, black, white, spotted, reddish). Evidence 2: chicks are 4–6 oz, mom is 6 lb. Evidence 3: chicks have tiny combs; mom has large comb. Evidence 4: chicks act calm, active, or shy.

Read Carlos’s account: He grows four marigolds from one parent’s seeds. Similarities—Evidence 1: all have orange flowers. Evidence 2: all have feathery leaves. Evidence 3: all grow bushy with branches. Evidence 4: all make seeds. Differences—Evidence 1: heights vary 15–20 inches (parent 18). Evidence 2: flower numbers vary 20–30 (parent 25). Evidence 3: first bloom varies week 7–9 (parent week 8). Evidence 4: stems vary thin to thick. How are the plants like but not exactly like the parent?
