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.
Kids learn by watching short, engaging video lessons.
So, evaporation is the process where liquids change to a gas or vapor. Evaporation occurs when the particles in the liquid, for example, water, have been heated and it’s caused their particles to become looser or freer. Now, these particles leave the surface of the liquid and evaporate into the air. So, there are different factors that will affect the rate of evaporation. That means how quickly it happens or how much it happens. So, these factors are things like the surface area of the liquids and the temperature and if there's any wind present at all. Evaporation increases with an increase in surface area. So, the bigger the surface area, the more evaporation. This is because the large surface area that's exposed to the air means that more molecules can escape into the air. And if there's any wind moving over the water or the land surface, that can also help to carry any of the water vapor, essentially drying the air and leads to an increased evaporation rate. Evaporation happens naturally every single day. For example, after it rains, the puddles may form, and these will then dry up by being evaporated over the course of the day. And similarly, once you've mopped the floor, it won't stay wet for long because it will evaporate.
Kids earn more screen time by answering fun educational questions.
Here are some example of questions about this video that kids may be asked in the 1Question app to earn screen time.
A liquid will evaporate faster if it is1) boiling2) frozen3) refrigerated4) room temperature
Evaporation increases with1) increased surface area of liquid2) decreased surface area of liquid
Evaporation is a1) process2) state of matter3) temperature
Evaporation is a process where which state of matter changes to which state of matter?1) liquid changes to gas2) Liquid changes to solid3) solid changes to gas4) gas changes to solid
What factors can you remember which influence the rate of evaporation?1) Surface area of liquid, temperature and wind2) Moon phase, precipitation, season, and ocean currents3) Time of day, soil type, water quality, and cloud cover4) Altitude, latitude, and longitude
What happens to particles from liquids during evaporation?1) They loosen and leave the surface of the liquid into the air2) they dissapear into the air3) bonds tighten4) the move slowly
What happens to the temperature to cause evaporation?1) rises (heats up)2) falls (cools down)3) stays the same4) fluctuates
Why do you think all of the sea does not evaporate?1) different temperatures wind and surface areas2) Because the sea is too cold to evaporate3) Because the sea is too salty to evaporate4) Because the sea is too deep for the sun to reach and cause evaporatio
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.
