OOBLECK DEMONSTRATION

Materials

Corn Starch

Water

Mixing Bowl

Hands

Willing Participants

Food Coloring

Wooden Spoon

Recipe

1. Add your pre-measured amount of cornstarch to the mixing bowl.

2. Slowly add water while

mixing until the consistency of the mixture thickens.

Note: Adding too much water will cause the demo not to reach the proper “FEEL”.

3 minutes

OOBLECK DEMONSTRATION

Now that you have formed your Oobleck answer questions#1-3. Question 3 is asking about the STATE OF MATTER thismixture has become.

Page 4: STATES OF MATTERkinga2.weebly.com/uploads/3/7/4/3/37431997/states_of_matter.pdf · A type of change in which the form of matter is altered but NO new substance is made Most times,

THE SCIENCE BEHIND IT

Oobleck is what scientists call a “Non-Newtonian” liquid

Newton stated individual liquids flow at consistent, predictable rates-- Oobleck does NOT follow those rules

Oobleck is a SUSPENSION, meaning that the grains of starch are not dissolved, they are just suspended and spread out in the water. If you let Oobleck sit for an while, the cornstarch would settle to the bottom of the bowl.

So why does this concoction act the way it does? Most of it has to do with pressure. The size, shape, and makeup of the cornstarch grains causes the cornstarch to “lock-up” and hold its shape when pressure is applied to it.

All matter is composed of particles (atoms) that have attractive forces between them.

Kinetic Energy : The energy produced by an object in motion

SOLIDSVery little Kinetic Energy

particles vibrate in place

Tightly packed particles with strong bonds.

Have a definite shape and definite volume

Rigid, not very compressible

LIQUIDSMedium amount of Kinetic Energy

Moderate amount of particle movement

Tightly packed, but far enough apart to slide over one another.

Have indefinite shape and definite volume. (takes the shape of the container it is in)

BUT WHAT HAPPENS IF YOU RAISE THE TEMPERATURE TO SUPER-HIGH LEVELS…BETWEEN 1000°C AND 1,000,000,000°C ?

Will everything

just be a gas?

PLASMAVery high Kinetic Energy

Plasma is different from a gas, because it is made up of groups of positively and negatively charged particles.

Like other gases has an indefinite shape and indefinite volume. Examples?

Fluorescent bulbs

Lightening

Plasma has an indefinite shape and indefinite volume.

Total opposite of PLASMA

Unexcited atoms with almost no movement

Created when the temperature of matter is closest to absolute zeroAn ice cube reaches this temperature, atoms begin to clump together, cant move at all and lose all their energy and become the same

MIXING METALS WITH METALS OR NON-METALS

An alloy is a combination of metals or a combination of

one or more metals with non-metallic elements.

The resulting mixture forms a substance with properties that often differ from those of the pure substance, such as increased strength or hardness, or color.

Example: gold and copper produces “red gold”, gold and silver becomes “white gold”, and silver combined with copper produces “sterling silver”.

Example: iron and carbon produce “steel”
