WHAT TO INCLUDE IN YOUR POSTER:



Write the Poster title - PROPERTIES OF WATER
In the Upper right corner, write all your group member’s names
and period
You are to include all of the following tasks on your poster.
TASK 1: POLARITY

Draw and color (Oxygen-RED and Hydrogen- BLUE) water molecule and the valence electrons of
oxygen and hydrogen. Draw in where the slight negative and slight positive charges are on the
molecule below.
o On the back side of your jigsaw, answer the questions under POLARITY.
TASK 2: HYDROGEN BONDING

Cut out the image below and paste it on your poster. Color (Oxygen-RED and Hydrogen- BLUE)
water molecules held together by hydrogen bonds. Add ARROWS pointing to the all the
hydrogen bonds in this image.

On the back side of your jigsaw, answer the questions under HYDROGEN BONDING
TASK 3: COHESION


Either cut out the image to the right and color it OR
draw your own representation of this image on the
poster. Label the image COHESION.
On the back side of your jigsaw, answer the
questions under COHESION.
TASK 4: ADHESION
 Cut out and color the picture below, color the liquid BLUE.
 Paste it on your poster and label it ADHESION.
Adhesion pulls the liquid up
the sides of the straw.

On the back side of your jigsaw, answer the
questions under ADHESION.
TASK 5: SOLUTIONS


Cut out the image to the right and paste it on your poster.
Label the solute and solvent. Color the solute and solvent.

On the back side of your jigsaw, answer the
questions under SOLUTIONS.
TASK 6: UNIVERSAL SOLVENT

Cut out and color the images below. Color Cl GREEN,
Color Oxygens RED, color H BLUE, and color Na purple.

On the back of your jigsaw, answer the questions under UNIVERSAL SOLVENT
TASK 7: DENSITY
 Draw a picture of a glass of soda with ice in it.
 On the back of your jigsaw, answer the questions under DENSITY.
