Are you looking for fun science games that you can use to help your child understand more about how the world works and help her to become more perceptive?
Then the fun science games below are just what you are looking for.
Bubble Machine Game
(Teaches a law of gases)
How much water can fit in a bottle? It depends on the size…right?
But there is also one other very important factor to consider and that’s temperature.
You can use this game to literally show your child that gases contract with lower temperatures and expand when they get warmer.
Here’s what you’ll need:
An empty 20-once bottle without the cap
A wide glass of clean water
Bubble solution made from dish soap and a ¼ cup of water put into a bowl
Here’s what you’ll do:
Put the mouth of the bottle into the water. As expected nothing happens.
Dry the bottle. Now this time put it into the freezer for about five minutes. Once the five minutes is up put the mouth of the bottle into the water. This time you’ll notice that air escapes from the down turned bottle into the water.
Dry the bottle again. Put it into the freezer for another five minutes. This time put the mouth of the bottle into the bubble solution you left in the bowl. Next put the bottle mouth up on a table. You’ll notice that it blows a bubble. Repeat this process until the bottle has reached room temperature and the bottle no longer blows bubbles.
How you can explain what happened to your children?
When you put the bottle into the freezer the gases inside contract. In other words the molecules, which are like little balls of “stuff” that are floating around start getting closer to each other.
When you take the bottle out of the freezer the gases warm up so the molecules have more energy and move away from each other. When this happens they run out of room and have to push themselves out of the bottle causing it to blow bubbles.
The Balloon Won't Pop!
(Teaches a law of physics)
When you stick a needle into a ballon it pops. But why?What’s the reason a balloon pops when you stick a needle in it?
The fun science game show below will help your child to know the answer to that question and see that there is more to the world than meets the eyes.
What You’ll Need For This Fun Science Game:
1 role of clear tape
1 straight pin
What you’ll do:
Blow up the balloon, then take one two-inch strip of tape and place it on the balloon. Then put another two-inch strip of tape and place it over the other so that they make an “X” on the balloon.
Puncture the center of the “X” with your straight pin. You’ll notice that the balloon doesn’t pop.
Remove the pin and watch the hole. Some air should be escaping and the crack should slowly widen. If not then squeeze the balloon. Once the crack reaches the edge of the tape the balloon should pop.
Why did the balloon pop when the crack reaches the edge of the tape?
It’s because of a phenomenon called catastrophic crack propagation.
You see once the hole reaches the edge of the tape it spreads incredibly fast ripping the balloon.
The tape slows this process considerably by holding the balloon together and preventing the crack from spreading too fast.
When the crack does reach the edge the crack rips the balloon apart faster than the speed of sound.
So the “pop” that you hear is actually a small sonic boom!
