Science Investigations and Concepts: Earth and Space/Matter

Front

What is thermal conductivity?

Back

Thermal conductivity is the ability of a material to conduct heat. Materials that conduct heat well, like metals, have high thermal conductivity.

Front

What does it mean for a material to be soluble in water?

Back

A material is soluble in water if it can dissolve in water to form a solution. For example, salt is soluble in water.

Front

What is electrical conductivity?

Back

Electrical conductivity is the ability of a material to conduct electric current. Metals like copper and aluminum are good conductors of electricity.

Front

What are physical properties of matter?

Back

Physical properties are characteristics of a substance that can be observed or measured without changing its identity, such as color, shape, and density.

Front

What does it mean for a material to be bendable?

Back

A bendable material can be shaped or bent without breaking. Examples include rubber and certain metals.

Front

What is a magnet?

Back

A magnet is an object that produces a magnetic field, which can attract or repel certain materials, such as iron.

Front

What is the difference between conductors and insulators?

Back

Conductors allow heat and electricity to pass through them easily, while insulators resist the flow of heat and electricity.

Front

What is matter?

Back

Matter is anything that has mass and takes up space. It can exist in different states, such as solid, liquid, or gas.

Front

What is a solution?

Back

A solution is a homogeneous mixture of two or more substances, where one substance (the solute) is dissolved in another (the solvent).

Front

What is density?

Back

Density is the mass of a substance divided by its volume. It determines how heavy an object is for its size.
