Understanding Matter and Its Properties

In this video, fifth-graders are introduced to Chapter 2, Lesson 1 of the ecosystem restoration unit, focusing on Activity 4. The lesson explores the concept of matter through a demonstration using balloons filled with water, air, and light. Students are encouraged to think about whether water, air, and sunlight are made of matter. The video concludes with a discussion on the matter chart, highlighting that water and air are made of matter, while sunlight is not.
