About This Quiz

There's a good reason why we're all taught science from the time we are small until we graduate from higher education. With a world that's ever-evolving, filled with humans who are naturally curious of things around, above and below, there will always be many scientific facts and figures that will be updated and enhanced through time. 

Even ancient scientists know this. Some of them postulated one thing or another about a certain thing or event, only to have their findings refuted by another scientist studying the same thing. Meanwhile, the earth, or mother nature, has its own developing and updating processes, ones that greatly affect all creatures inhabiting the planet. Then of course, outside the planet, there are also many changes happening, ones that could impact us here on earth. 

Yes, that is how science rules our daily life. Some of the scientific knowledge we learn in school are highly practical, while some are preparations for when we decide to specialize on certain fields when we grow up. It's still a win-win situation nonetheless, so learning some science is not such a bad thing for us. Do you think you can answer many of these science-filled pop quiz questions? Discover and see for yourself!

For every action, there is an equal and opposite…what?
Reaction
It’s one of the basic laws of the universe: Any action will have a reaction equal and opposite to it. This is why jet engines can make planes fly, for example.

Why is it a bad idea to be in an open field during a thunderstorm?
Flooding
Strong winds
Lightning strike
Electricity tends to find the shortest way from one place to another. If you’re the tallest object in an open field during a storm, you’re the lightning rod, therefore it will strike you. It’s the same reason you should avoid tall trees when outside, because the lightning will find them and strike, which could hurt you in the process.
Flying objects

Why is there a “dark side” to our moon?
It has dark soil there
We never see that side
The time it takes for the moon to orbit around the Earth is about the same time it takes to spin around its own axis. That means the moon always shows us the same side all the time. The outer side is therefore dubbed as the “dark side” because we never see it facing the earth.
It's near the shadowy edges
It has the remains of a civilization there
