Experiment with Gummies

Steps

Put one of your gummies
in the cup of water.

-This is your
dependent variable.

Leave the other gummy
untouched.

-This is your control
variable.

Osmosis

The transfer of water.

A special type of facilitated diffusion.

Uses aquaporin for transportation.

Water moves until it reaches a
balanced point in both solutions.

-Water moves toward the solution
with more solute.

Multiple Choice

What does osmosis transfer?

• Ions

• Water

• Oxygen

• Food

Multiple Choice

The purpose of osmosis is to reach a ___ point.

• balanced

• unstable

• new

• better

3 Situations

Hypertonic

-More solute on
outside.

-Causes cell to
shrivel.

Isotonic

-Equal amount of
solute and solvent
on both sides.

-Everything stays the
same.

Hypotonic

-More solute on
inside.

-Causes cell to burst.

Multiple Choice

Where will the water travel in a hypertonic solution?

• Inside

• Already equal

• Outside

Multiple Choice

Where will the water travel in a isotonic solution?

• Inside

• Outside

Multiple Choice

Where will the water travel in a hypotonic solution?

• Inside
