Do you struggle with balancing your kids’ screen time with their education? Say hello to 1Question, the app that solves this problem with a fun twist! Our app lets your child earn screen time minutes in their favourite apps by watching educational videos and correctly answering quiz questions. And the best part? You get to decide which apps to lock behind learning using 1Question.

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.

Answer time

Kids earn more screen time by answering fun educational questions.

2) fixed shapefixed volumeFill no space

3) No fixed shapeNo fixed volumeInvisible

4) No fixed shapefixed volumeInvisible

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.
