Get ready to WOW your kids with a super EASYscience experiment for kids!
I have been there too!
Thisrising water experimentis NOT one of those science experiments.
Thisthe burning candle experimentis actually super simple and uses common things you have in your kitchen already!
Plus there is a free science worksheet to help teach the scientific method with older elementary age students too.
Thescience worksheetpdf file will open in a new window for you to save the freebie and print the template.
I suggest using a chunky tall candle so the water wont overwhelm the candle and it has some stability.
If you use a tall tapered candle, you may want some playdough to hold it in place.
But Id say 1/2 cupr or so was right for us.
We mixed our water with food coloring first and then poured it on the bottom of the dish.
I suggest filling out the pdf science worksheets at this point to help students make educated guesses or hypothesis!
Light the candle and put a mason jar over the top of the candle.
WARNING: Fire is dangerous and this should only be done under the carefuly observation of a responsible adult.
like use common sense when completing this science activity.
Have students watch carefully.
The candle will start lit, but wont stay that way for long!
CAUTION: The glass will become hot to the touch.
Fire needs oxygen to live.
But something else happened when the candle was burning, the flame heated up the air inside the glass.
The hot air expanded quickly and created higher air pressure inside the glass than outside the glass.
To restore equilibrium, some of the high-pressure air inside escaped from under the glass.
You may have seen tiny bubbles escaping from underneath the glass.
When the flame extinguished, the air inside the glass began to cool down.
Cooling air contracted, which in turn lowered the air pressure inside the glass.
The remainder of the blue water was sucked in to the mason jar.
After you explain what happened, ahve children write their conclusion.
