Begin by placing a generous layer of playdough on the tray and smoothing it slightly. The dough should be thick enough to hold deep impressions without tearing. Set out several toy bugs nearby so children can choose which insects to explore.

For best fossil impressions, place the bug upside down before pressing it into the playdough. Turning the bug over allows the raised details on the underside, such as legs, wings, and body segments, to press more clearly into the dough. Taking a moment to examine the bug’s shape and texture before pressing encourages close observation and supports early science skills while naturally pacing the activity.

Optional tools like magnifying glasses and brushes can be added to extend the insect sensory activity and encourage more detailed exploration.
