Скачать или смотреть Bubble Lab: Lesson 3 – The Role of Glycerine | EZ Science Kids Level 1

Welcome to EZ Science Kids!

In this final Bubble Lab video, our EZ Science Kids Ambassador demonstrates the experiment they will teach to their Explorer — discovering what makes bubbles last longer.

In this lesson, we explore:
• Why bubbles pop over time
• What evaporation is
• How glycerin changes bubble strength
• Why bubbles made with glycerin last longer than bubbles made with soap and water alone

Ambassadors compare two bubble solutions and guide Explorers through observations, predictions, and explanations using clear, simple science language.

This experiment brings together everything learned in the Bubble Lab series — surface tension, soap molecules, air pressure, and evaporation — and prepares Ambassadors to confidently teach science through hands-on discovery.
