What is density?

Back

Density is the mass of an object divided by its volume, typically expressed in grams per milliliter (g/ml).

Front

What happens when two liquids of different densities are mixed?

Back

The liquid with the lower density will float on top of the liquid with the higher density.

Front

What is buoyancy?

Back

Buoyancy is the ability of an object to float in a fluid, which is determined by the density of the object compared to the density of the fluid.

Front

What is the independent variable in an experiment?

Back

The independent variable is the factor that is changed or controlled in an experiment to test its effects on the dependent variable.

Front

What is the dependent variable in an experiment?

Back

The dependent variable is the factor that is measured or observed in an experiment.

Front

What is friction?

Back

Friction is the force that opposes the motion of an object when it comes into contact with another surface.

Front

What is gravity?

Back

Gravity is the force that attracts two bodies toward each other, pulling objects toward the center of the Earth.

Front

What is inertia?

Back

Inertia is the tendency of an object to resist changes in its state of motion; an object at rest stays at rest, and an object in motion stays in motion unless acted upon by an external force.

Front

What is a chemical reaction?

Back

A chemical reaction is a process that leads to the transformation of one set of chemical substances to another, often involving the formation of bubbles, heat, or color change.

Front

What is a control in an experiment?

Back

A control is a standard against which the results of an experiment are compared, ensuring that the test is fair.
