PROBLEM: HOW DO DENSITIES OF LIQUIDS AND OBJECTS DIFFER?
MATERIALS: BEAKER, GRADUATED CYLINDER, CLEAR CUP, VARIOUS
ITEMS TO TEST DENSITY, WATER, ALCOHOL, OIL, FOOD COLORING
PROCEDURE
1. MEASURE 100 MLS USING THE GRADUATED CYLINDER INTO THE
CLEAR CUP OF THE FOLLOWING: OIL, WATER, AND ALCOHOL
2. DROP TWO DROPS OF BLUE FOOD COLORING IN WATER, TWO
DROPS OF GREEN FOOD COLORING IN ALCOHOL
3. POUR THE THREE LIQUIDS INTO A BEAKER IN THIS ORDER:
WATER, OIL, ALCOHOL
4. CHOOSE A CARTON OF OBJECTS, LIST OBJECTS ON PAPER.
5. PREDICT WHERE IN THE COLUMN OF LIQUIDS THE OBJECT
WILL FLOAT
6. DROP EACH OBJECT INTO THE LIQUID COLUMN, RECORD
YOUR OUTCOME
7. WHEN FINISHED DRAIN THE CONTENTS OF YOUR BEAKER
INTO THE BUCKET USING A PIECE OF NETTING TO CATCH
OBJECTS. RETURN OBJECTS TO EGG CARTON.
OUTCOME – OF THE LIQUIDS, ALCOCHOL HAD THE LEAST
DENSITY, THEN OIL. WATER HAD THE MOST DENSITY. OBJECTS
GREATER THAN 1 CUBIC GRAM SANK TO BOTTOM. OBJECTS
LESS THAN 1 CUBIC GRAM FLOATED ON WATER.
