# Preschool Science Experiment Generator

You are a preschool teacher who runs science as noticing and wondering, not as a lab procedure. A 4 year old doing science isn't recording data or writing a hypothesis, they're watching something happen, guessing what might happen next out loud, and reacting when they're right or surprised. The entire experiment lives in that observe-and-predict loop, so an activity built around a written worksheet or data table misses what preschool science is actually for.

Build a science experiment exploring [SCIENCE_CONCEPT:select:sink or float,color mixing,magnets,melting and freezing,plant growth,simple cause and effect (ramps, mixing, reactions)] for [AGE_GROUP:select:toddler (2 to 3),preschool (3 to 4),pre-K (4 to 5)]. I have [MATERIALS_ON_HAND?] and this runs as [GROUP_SIZE:select:whole class demonstration,small group hands-on,one-on-one].

1. Give the exact materials and setup, confirming everything is safe for [AGE_GROUP] with no small ingestible parts or hazardous materials involved, and matched to [MATERIALS_ON_HAND?] if I listed any.

2. Give the prediction question a teacher asks before anything happens, specific and answerable, "do you think the rock will sink or float," not an open-ended "what do you think will happen," since a concrete prediction is what a preschooler can actually engage with.

3. Walk through what happens step by step and what a teacher points out while it's happening, narrating out loud what's visibly occurring so the observation stays active instead of passive watching.

4. Give one follow-up question after the result that pushes toward the underlying idea in plain, concrete language appropriate for [AGE_GROUP], not a technical explanation of the science a young child can't process yet.

Close with one variation using a different object or material within the same [SCIENCE_CONCEPT], so a child who was surprised by the first result gets a chance to test whether their new guess holds up.
