SCIENTIFIC INVESTIGATION
WHILE WALKING TO SCHOOL, ANA NOTICED THAT THE PLANTS BESIDE THE ROAD WERE WILTING FASTER THAN THE PLANTS IN HER GARDEN. THIS MADE HER CURIOUS ABOUT THE DIFFERENCE. WHAT STEP OF THE SCIENTIFIC INVESTIGATION IS SHE PERFORMING?
OBSERVATION
IN A CUP OF COFFEE, SUGAR DISAPPEARS AFTER STIRRING AND BECOMES EVENLY DISTRIBUTED THROUGHOUT THE LIQUID. WHAT IS SUGAR CALLED?
SOLUTE
A STUDENT CONTINUES ADDING SUGAR TO WATER UNTIL NO MORE SUGAR DISSOLVES, EVEN AFTER STIRRING. WHAT TYPE OF SOLUTION HAS BEEN FORMED?
SATURATED SOLUTION
A LIQUID TURNS BLUE LITMUS PAPER RED. WHAT IS THIS SUBSTANCE CLASSIFIED AS?
ACID
THIS LABORATORY EQUIPMENT ALLOWS TO HEAT SUBSTANCES USING AN OPEN FLAME.
BUNSEN BURNER
AFTER OBSERVING THAT HER PLANTS WERE WILTING, ANA ASKED, "DO PLANTS GROW BETTER WHEN WATERED EVERY DAY?" WHAT STEP OF THE SCIENTIFIC INVESTIGATION IS THIS?
ASKING A QUESTION
WATER IS ADDED TO POWDERED JUICE UNTIL IT COMPLETELY DISSOLVES. WHAT IS WATER CALLED?
SOLVENT
ANOTHER STUDENT ADDS ONLY A SMALL AMOUNT OF SUGAR TO WATER, AND ALL OF IT DISSOLVES EASILY. WHAT TYPE OF SOLUTION IS THIS?
UNSATURATED SOLUTION
A HOUSEHOLD CLEANING SOLUTION TURNS RED LITMUS PAPER BLUE. WHAT IS THIS SUBSTANCE CLASSIFIED AS?
BASE
A TEACHER WANTS HIS STUDENTS TO VIEW MICROSCOPIC ORGANISMS, LIKE PLANT AND ANIMAL CELLS. WHICH LABORATORY EQUIPMENT SHOULD HE GIVE TO HIS STUDENTS?
MICROSCOPE
TO TEST HIS PREDICTION, MIGUEL PREPARED TWO IDENTICAL PLANTS, GAVE THEM THE SAME AMOUNT OF WATER, AND PLACED THEM IN DIFFERENT LOCATIONS WITH DIFFERENT AMOUNTS OF SUNLIGHT. WHAT STEP OF THE SCIENTIFIC INVESTIGATION IS THIS?
PLANNING AND CONDUCTING AN INVESTIGATION
A MIXTURE OF SALT AND WATER APPEARS UNIFORM BECAUSE THE SALT CAN NO LONGER BE SEEN. WHAT IS THIS HOMOGENEOUS MIXTURE CALLED?
SOLUTION
TWO DRINKS CONTAIN THE SAME AMOUNT OF WATER, BUT ONE HAS A MUCH GREATER AMOUNT OF DISSOLVED POWDERED JUICE. WHAT SCIENTIFIC TERM DESCRIBES THIS SOLUTION?
CONCENTRATED SOLUTION
A SOLUTION THAT HAS A PH LEVEL OF 7.
NEUTRAL
MICA WAS HEATING A BEAKER FOR AN EXPERIMENT. SHE WANTS TO TRANSFER IT TO ANOTHER AREA. WHAT LABORATORY EQUIPMENT CAN BE USED TO TRANSFER THE HOT BEAKER?
BEAKER TONGS
AFTER MEASURING THE HEIGHT OF BOTH PLANTS FOR TWO WEEKS, MIGUEL STUDIED HIS DATA AND DETERMINED THAT THE PLANT RECEIVING MORE SUNLIGHT GREW TALLER. WHAT STEP OF THE SCIENTIFIC INVESTIGATION IS HE PERFORMING?
ANALYSIS OF RESULTS
SAND IS MIXED WITH WATER, BUT IT SETTLES AT THE BOTTOM INSTEAD OF DISSOLVING. WHAT SCIENTIFIC TERM DESCRIBES THIS PROPERTY OF SAND?
INSOLUBILITY
COCOA POWDER DISSOLVES MORE QUICKLY IN HOT WATER THAN IN COLD WATER. WHICH FACTOR AFFECTING SOLUBILITY IS RESPONSIBLE?
TEMPERATURE
WHEN AN ACID REACTS WITH A BASE, A NEW SUBSTANCE SUCH AS SODIUM CHLORIDE IS FORMED. WHAT IS THIS TYPE OF SUBSTANCE CALLED?
SALT
SUKUNA WANTS TO TRANSFER A FEW DROPS OF IODINE SOLUTION ONTO A SPECIMEN. WHAT LABORATORY EQUIPMENT CAN HE USE?
DROPPER
MIGUEL PREDICTED THAT "IF A PLANT RECEIVES MORE SUNLIGHT, THEN IT WILL GROW TALLER THAN A PLANT KEPT IN THE SHADE." WHAT STEP OF THE SCIENTIFIC INVESTIGATION IS THIS?
HYPOTHESIS
WHEN SUGAR IS STIRRED INTO WATER UNTIL IT BECOMES EVENLY MIXED, WHAT PROCESS IS TAKING PLACE?
A STUDENT CRUSHES SUGAR INTO SMALLER PIECES BEFORE MIXING IT WITH WATER, CAUSING IT TO DISSOLVE MORE QUICKLY. WHICH FACTOR AFFECTING SOLUBILITY IS ILLUSTRATED?
PARTICLE SIZE
A STUDENT USES A SPECIAL PAPER THAT CHANGES COLOR TO DETERMINE WHETHER AN UNKNOWN LIQUID IS ACIDIC OR BASIC. WHAT IS THIS TESTING MATERIAL CALLED?
LITMUS PAPER
GOJO ACCIDENTALLY SPLASHED A CHEMICAL TOWARD HIS EYES AND WANTS TO PREVENT INJURY BEFORE STARTING THE ACTIVITY. WHAT LABORATORY EQUIPMENT CAN HE USE TO PROTECT HIS EYES NEXT TIME?
SAFETY GOGGLES
