What is a solid?

100

This force lets water form droplets and helps insects like water striders stay on the surface.

What is surface tension?

100

This is a mixture where one substance dissolves evenly in another.

What is a solution?

100

This method separates an insoluble solid from a liquid using filter paper.

What is filtration?

100

Everything around us that has mass and takes up space is called this.

What is matter?

200

This change of state happens when liquid water becomes water vapour.

What is evaporation?

200

This is calculated using mass divided by volume.

What is density?

200

In salt water, salt is this part of the solution.

What is the solute?

200

This method separates mixtures based on particle size.

What is sieving?

200

This is the amount of matter in an object.

What is mass?

300

Gas particles are easy to compress because there is a lot of this between them.

What is space?

300

An object will usually float if it is less dense than water. This means its density is ______ than water’s density.

What is lower?

300

A mixture where particles settle over time is called this.

What is a suspension?

300

This method uses a magnet to remove iron from a mixture.

What is magnetic separation?

300

This is how much space an object takes up.

What is volume?

400

This change of state happens when a gas cools and becomes a liquid.

What is condensation?

400

This method finds the volume of irregular objects by measuring the rise in water level.

What is water displacement?

400

This term describes a solution that contains a lot of dissolved solute.

What is concentrated?

400

This method separates a dissolved solid from a solution by forming crystals.

What is crystallisation?

400

A substance made of only one type of atom is called this.

What is an element?

500

When water is heated, its particles move faster. This causes the water’s ______ to increase.

What is temperature?

500

When water is placed in a very thin tube, it can rise up the tube because of attraction between water and the tube. This is called this.

What is capillary action?

500

This is a pure substance made of two or more elements chemically joined.

What is a compound?

500

This method separates a mixture by carefully pouring off the liquid from solids that have settled at the bottom.
