Information for parents →Seven stories, and discoveries beyond the screen
After watching, choose a conversation or a game together. Activities, short audio stories in Greek and English, and detailed parent notes accompany the series. Activities require adult supervision and age-appropriate materials.
The Parent area provides sources, audio recordings, short clips and activity cards. A simple grown-up step precedes access to these tools.
Open the Parent area →From the people in the laboratory, for families
Sikalias WhyLab shares how science thinks with children and parents: observe, ask questions, examine evidence and recognise what we do not yet know. The series receives scientific editorial oversight from the R&D team at Sikalias Pharmaceutical Laboratories, initiated by pharmacist Stasinos Sikalias. Eirini is an adult member of Sikalias R&D.
The children’s area supports education and family conversation, without prompts to buy products. An unfamiliar name does not prove danger and natural origin does not guarantee safety. We distinguish ingredient role, safety in the specific use, the environment and company formulation choices.
