Capillary Action Snowflakes can be a fun science activity for people of all ages. We provide these generalizations as guidelines about what children at different ages might do during Capillary Action explorations at the Discovery Center’s Experiment Station, in the kitchen at home, or at school. Listed below are science and technology process skills that children may be practicing during their explorations. Please remember: each child develops at a different rate, so some children in each age group may be able to do some of the things described in the age group before or after their own.
