## Learning time​

Kids learn by watching short, engaging video lessons.

Gas is one of the three states of matter. And the three properties of gas you need to remember are gases have no fixed shape, they have no fixed volume, and they fill all of their available space. So, gases have no definite shape and gas behaves very differently to solids and liquids because we cannot really see or touch gas in the same way that we can with solids and liquids. But there are gases around us all the time. The air we breathe in and the air we the breathe out are both gases. That's oxygen and carbon dioxide. Now, the particles in gas are very, very spaced out so there's lots of room for these particles to move around. And this is why gases move so freely and why they expand to fill all of their available space. Some examples of gases are helium which helps our balloons float and carbon dioxide. So, gases have no fixed weight, no fixed shape, and they fill all of their available space.

Kids earn more screen time by answering fun educational questions.

## Recreational screen time

Kids can use the screen time minutes they earned to unlock the apps selected by their parent e.g. games, social media, streaming, etc.

## Out of time

When screen time minutes run out, kids are locked out and need to complete more learning in 1Question to earn more time.
