RESEARCH QUESTION: WHAT EFFECT DOES FREEZING TEMPERATURE HAVE ON WATER?
HYPOTHESIS: I JUST THOUGHT THE WATER WOULD FREEZE.
METHOD: COMPLETELY FILL A PLASTIC BOTTLE WITH WATER GETTING OUT ALL THE AIR AND CAPPING IT TIGHTLY AND PLACE THE BOTTLE IN A PLASTIC BAG AND PUT IT IN THE FREEZER OVER NIGHT.
OBSERVATION: THE NEXT DAY WE GOT THE BOTTLE OUT AND ON ONE SIDE OF THE BOTTLE IT WAS BULGED OUT AND EXPANDED.
CONCLUSION: MY HYPOTHESIS WAS WRONG BECAUSE IT DIDN’T FREEZE IT BULGED OUT FROM THE WATER FREEZING AND EXPANDING.
APPLICATION: WATER GETS INTO PAVEMENT AND CRANKS AND EXPANDS WHEN FROZING TO BRAKE THE PAVEMENT.
