Melting micro-lesson

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.

So, melting is the process of changing something from a solid into a liquid and it's the opposite of freezing. So, when the temperature rises, it gets hotter, and the solid matter melts. The particles in the solid then loosen their bond to each other and then are able to move more freely around each other so the matter is then liquid and no longer solid. But it's important to remember that melting is the process of changing a solid back into a liquid. So, some solids cannot be changed into a liquid and when they're heated up, they have a completely different reaction to the heat. For example, paper will burn when heated so, therefore, cannot be melted. Now, the temperature at which something begins to melt is called its melting point. Now, ice is the solid version of water and the melting point for ice or water is 0 degrees. Other solids have very different melting points. For example, glass melts at an extremely high temperature at between 700 degrees and 800 degrees but metals will have different melting points. One example is lead. Lead melts at a temperature of about 327.5 degrees.

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.
