In this state of matter, particles are locked tightly together, vibrating but keeping their own shape.
Solid
True or False: A glass cup sitting on your desk with no liquid in it is actually completely empty.
False
The science word that describes "how thick a liquid is."
Viscosity
When we stir sugar into warm water, the solid sugar disappears because it does this.
Dissolves
Oobleck is a mixture of water and this soft, powdery solid kitchen ingredient.
Cornstarch
This state of matter has a definite volume, but no shape of its own—it flows and takes the shape of its container.
Liquid
When we pushed our cup upside down into the water, this crumpled object stayed completely dry because air took up the space inside the cup.
If a liquid flows very, very slowly, we say it has a _______ viscosity.
High
A mixture where a solid completely dissolves and hides in the microscopic spaces of a liquid is given this scientific name.
Substances like Oobleck that break the rules of solids and liquids are called this type of fluid.
Non-Newtonian Fluid
Particles in this state are spread far apart, have high energy, and fly around to fill whatever space they are in.
Gas
This invisible force pushing in all directions is strong enough to keep an index card stuck to an upside-down cup of water.
Air Pressure
We used this flat kitchen item covered in wax paper to race drops of water, oil, and syrup.
Plate
When we mix sand and water, the sand does not dissolve; instead, the heavy sand eventually does this.
Sinks to the bottom
To make Oobleck act like a hard solid, you must apply a quick, hard push, which is called this.
Force
In our Day 1 experiment, we melted ice by transferring this.
Heat or Energy
When we tilted our cup underwater, we saw the trapped air escape in this circular, floating form.
Because olive oil is less dense than water, it does this when you pour them into the same cup.
Floats on top
In a mixture like olive oil and water, the two liquids refuse to stay combined, proving they are a regular mixture and not one of these.
A solution
When you stop moving your hands, the solid ball of Oobleck immediately turns back into this state of matter.
The scientific word for anything in the universe that takes up space and has mass (weight).
Matter
When the air left our tilted cup and the water rushed inside to take its place, we said the water did this to the air.
If I pour 100 milliliters of water from a tall, skinny cup into a wide, flat bowl, the shape changes, but this stays exactly the same.
Volume
Because dissolving sugar in water is a physical change, you can easily get your solid sugar back out of the cup by letting the water do this.
Evaporate
When you apply force to Oobleck, the particles do this, which blocks the water from moving and makes it feel solid.
Tightly Packed
