Mystery Bag Observation
Kids use touch, sound, and smell (never sight) to describe and guess a hidden object — a hands-on intro to observation skills.
Sink or Float Predictions
Kids predict, then test, whether everyday objects sink or float — a simple hypothesis-and-test loop that’s real science.
Human Sorting Machine
Students become the "objects" and physically sort themselves into groups based on a rule only some of them are told.
Would It Survive? Habitat Match
Teams match animal cards to habitat cards and defend their reasoning based on the animal’s traits.
Logic Grid Lite
A simplified deduction puzzle — use a short list of clues and a grid to figure out who owns what, works alone or in pairs.
Two-Minute Mysteries
A short lateral-thinking puzzle is read aloud; students ask yes/no questions to figure out what really happened.
No activities match that combination — try a wider group size or "All grades."
