Sink or Float? Preschool Science Prediction and Recording Activity

Invite children ages 3–5 to predict, test, and observe which teacher-selected objects sink or float in water. This 12-page printable includes a child recording sheet for predictions and results, plus prompts to notice and discuss what happened. Use it for a supervised water-play science investigation that builds early skills in prediction, observation, and comparing objects. A grown-up safety reminder emphasizes shallow water, age-safe materials, close supervision, and emptying the container afterward.
