• Activity! • Draw the picture below. Use a Petri-Dish to

assist you. Label as “Before”.

• Activity! Swirly Milk, A fun starting off activity.– Fill the depression of the plate with whole milk.– Add one drop of different food colorings at 12, 3,

6, 9 O’clock of the plate.

OR


• Swirly Milk Continued.– Draw the plate.– Take a toothpick and dip it into detergent.– Touch detergent (Dawn) on toothpick into the

middle of the milk.– Record your findings with a detailed drawing.

• Draw a “After” Sketch of the SWIRLY MILK . Use a Petri-dish to assist you.

• Questions! Swirly Milk.– What happened to the milk? Why?


• How Swirly Milk Works – When you introduce detergent to the milk, several

things happen at once.

• The detergent breaks the surface tension (skin on the top of the water)

• Food coloring is now free to flow through the milk.

• Detergent reacts with milk…Creates motion

• Detergent breaks up fat in milk pushes color around.

• Continues for awhile and then stops.

• Water from your tap weighs the same as this water.

Density: 1 gram per cubic centimeter.

• Density: How much mass is contained in a given volume. We use grams/cm3

– (grams per cubic centimeter)

– Density = Mass divided by volume


MassD = ------------- = grams/cm3 Volume

• Polar molecule: One end of the water molecule tends to have a positive charge while the other has a negative charge.


• Which molecule below is polar?

Non-polar (lipids) equal charge.

• Activity! Making a surface tension speed boat.– Break a popsicle stick in half and place a small

amount of detergent on the end.– Place on a plate of water.– You only get one shot at this so enjoy.


• Questions to speed boat.– Sketch your boat in your journal and describe

it’s journey.– Why do you think the boat moved around?








• You can now complete this question.

• Activity! Polarity of water and observing cohesion– Add one drop of water to wax paper and sketch

what it does.– Move the drop around.


• Which is polar, and which is non-polar?

Water Droplets


Wax Paper = Non-Polar

Water Droplets Polar


Wax Paper = Non-Polar +/+



Wax Paper = Non-Polar -/-



Wax Paper = Non-Polar -/-

Water Droplets Polar +/-

• What did the molecules attach to? Why?

Wax Paper

Water Droplets

• What did the molecules attach to? Why?– Answer: Because the water molecules are polar,

they attached to themselves and stayed in a drop. The wax paper is non-polar, so the water did not mix with it.

Water Droplets

• Many products use polarity to help waterproof materials.

• Activity Demonstration! Oil and Water don’t…________?– Add a few drops of vegetable oil to a clear Petri-

dish using an overhead projector.– Describe what happens?– What happens when two oil bubbles meet?


• Answer: When two (Non-polar) oil bubbles meet, they join together to form a large bubble.


• Answer: When two (Non-polar) oil bubbles meet, they join together to form a large bubble.


• Add a few drops of food coloring to the mix.– How is the reaction different?– Is food coloring polar or non-polar?







• Where have we seen the picture below?


• Oil and water don’t mix.


• Oil and water don’t mix. An oil spill can cause severe damage to aquatic systems because of this property.
