Refraction 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, why do objects look different through water? Refraction. Light waves travel at different speeds when they go through transparent materials such as water or glass. When the light rays hit the water, they slow down. This causes the rays of light to change direction and bend through the water. This is refraction. Now, the angle of the refracted light and the angle of incidence are not equal. And we remember the angle of incidence is the angle between the incident rate and the normal line, that incident rate in the ray of light coming from the light source. The refraction creates illusions which means we are seeing things incorrectly. Because the light bends when it travels between air and water or glass, objects seen through these materials look bent or distorted but we know they're not really bent at all.

    1) incident ray
    2) reflected ray
    3) refracted ray
    4) water ray
  • When light hits the water, the objects in the water look...

    1) bent and distorted
    2) the same
    3) wet and smooth

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.
