What Is Matter? - The Dr. Binocs Show | Best Learning Videos For Kids | Peekaboo Kidz
Peekaboo Kidz
Overview
This video introduces the concept of matter, defining it as anything that has weight and occupies space (volume). It explains the three primary states of matter: solid, liquid, and gas, providing examples and characteristics for each. The video also includes simple experiments to demonstrate that air, a gas, has both volume and weight, confirming its status as matter. Finally, it briefly mentions other, less common states of matter.

Chapters
- Matter is defined as anything that has weight and takes up space, also known as volume.
- Weight refers to how heavy an object is.
- Volume is the amount of space an object occupies.
- Everything around us, including air, water, and physical objects, is composed of matter.
Understanding the definition of matter is fundamental to comprehending the physical world and the substances that constitute it.
A ball occupies a small volume, while the sun occupies a much larger volume.
- Matter exists in different states, with the three most common being solid, liquid, and gas.
- Solids maintain their own shape and do not flow easily; examples include tables, sugar cubes, and rocks.
- Liquids can flow and take the shape of their container, possessing weight; water is a common example.
- Gases are often invisible but are present everywhere, like the air we breathe.
Recognizing the different states of matter helps explain the diverse properties and behaviors of substances we encounter daily.
Ice is a solid, but when it melts, it becomes liquid water.
- Air, a gas, occupies space, which can be demonstrated by lowering an inverted glass into water.
- The water level inside the inverted glass is lower because the trapped air prevents it from filling completely.
- Tilting the glass allows air bubbles to escape, showing that air was indeed occupying that space.
- Air also has weight, which can be proven by balancing a meter stick with two balloons, then inflating one; the inflated side will dip due to the added weight of the air.
These experiments provide empirical evidence that gases, like air, are physical substances with measurable properties, reinforcing the definition of matter.
When one balloon is inflated and attached to a meter stick balanced on a string, the stick tilts down on the side with the inflated balloon, proving air has weight.
- While solid, liquid, and gas are the most common states of matter, other states exist.
- Man-made states of matter include plasma, fermionic condensates, and Bose-Einstein condensates.
Knowing about additional states of matter broadens our understanding of the physical universe and the possibilities of material science.

Key takeaways
- Matter is the fundamental building block of everything, defined by having mass (weight) and occupying space (volume).
- The three common states of matter—solid, liquid, and gas—exhibit distinct properties related to shape, flow, and volume.
- Solids retain their shape, liquids conform to their containers, and gases fill their entire container.
- Gases, like air, are often unseen but are demonstrably matter because they possess both volume and weight.
- Simple experiments can visually confirm the physical properties of gases, making abstract concepts more concrete.
- The study of matter extends beyond the three common states to include more complex forms like plasma and condensates.
