FIRST OF FOREMOST, EACH OF US BRING OUR OWN PLASTICINE TO CLASS WITH DIFFERENT COLORS WHICH IS RED, YELLOW AND BLUE. WE STARTED TO MAKE IT INTO DIFFERENT SIZE OF SHAPES.

WHILE MAKING THE PLASTICINE INTO DIFFERENT SIZE OF SHAPES, WE STARTED TO THINK OUR OWN IDEAS TO MAKE THE ARCH MORE INTERESTING AND STABLE SO THAT IT CAN WITHSTAND ANY FORCES AND PRESSURE.

NEXT, WE MAKE THE COLUMN OF THE ARCH IN 3 INCHES EACH, IN ORDER TO MAKE SURE OUR ARCH IS BALANCE, WE DOWNLOADED AN APPS WHICH IS BUBBLE LEVEL TO MEASURE THE BALANCING OF COLUMN OF THE ARCH.

THE ARCH WAS SUCCESSFULLY BUILT. WE STARTED TO TEST HOW HEAVY IT CAN WITHSTAND AND WE TRY OUR BEST TO MAKE IT STRONGER. 

THIS IS OUR ARCH. AS YOU CAN SEE BOTH OF THE COLUMN ARE ROUGHER SO THAT IT CAN BE BALANCED.

AFTER 2 HOURS OF THE ARCH BUILDING. NOW, IT'S TIME TO COMPARE WITH OTHER GROUPS TO TEST HOW HEAVY OUR OWN ARCH CAN WITHSTAND. EVENTUALLY, THE ARCH OF OUR GROUP CAN ONLY WITHSTAND 5 SMARTPHONES. 

REFLECTION

HENCE, THE REASON WHY OUR ARCH COLLAPSE AFTER PUTTING 5 SMARTPHONES IS BECAUSE THE COLUMN OF THE ARCH ARE NOT ROUGH ENOUGH. DURING THE PROCESS OF THIS ARCH BUILDING, I REALLY LEARNT A LOT THAT WE NEED TO BE EXTRA CAREFUL OF THE BALANCING OF THE ARCH SO THAT IT WON'T COLLAPSE EASILY.   

THESE ARE THE STEPS OF ARCH BUILDING OF OUR GROUP ( JANSON, JOYI, KIMBERLY)
