MOLECULES
• CLICK ON THE CHEMICAL WHICH IS A
MOLECULE:
WATER SODIUM
CARBON HYDROGEN
• REMEMBER:
–MOLECULES ARE MADE UP OF
MORE THAN ONE ATOM
–ELEMENTS ARE ONLY MADE UP
OF ONE ATOM AND ARE ON THE
PERIODIC TABLE
RIGHT!!
MACROMOLECULES
• THERE ARE FOUR MACROMOLECULES.
CLICK ON THE ONE THAT DOES NOT
BELONG.
WATER LIPIDS
PROTEINS NUCLEIC ACIDS
CARBOHYDRATES
• REMEMBER:
–MACROMOLECULES ARE VERY
LARGE MOLECULES
RIGHT!!
WATER IS A MOLECULE, BUT IT
IS A SMALL MOLECULE, NOT A
VERY LARGE MOLECULE

IF YOU FROZE THEN
THAWED AN APPLE, IT
WOULD GET MUSHY. WHY?
WATER IS THE UNIVERSAL SOLVENT
WATER SHOWS CAPILLARY ACTION
WATER IS HYDROPHOBIC
WATER EXPANDS WHEN IT FREEZES
Water IS the universal solvent, but this
means it dissolves many things. This
doesn’t explain the mushiness of the
apple.
