Grade 5 - Classroom Chemistry

What is a solid?

• When the molecules are running around at crazy speeds.

• When the molecules are close together and there is barely any movement.

• When the molecules are running around at slow speeds, but far apart.

• None

What is a liquid?

• When the molecules are going at a decent speed and a decent distance away.

• When the molecules aren’t moving at all.

• When the molecules are running in their own small circle away from each other.

• None

What is gas?

• When molecules are far apart and moving at crazy speeds.

• When molecules are moving super slow.

• When molecules are barely moving.

• None

What are the 8 methods of separating mixtures? ( All mixtures )

• Evaporation, distillation, sieve, decanting, buoyancy, magnetism, mass, filtering

• Evaporation, drinking, smelling, sieve, distillation, mass, filtering, buoyancy

• Distillation, drinking, sieve, filtering, mass, buoyancy, magnetism, decanting

• There are no methods of separating a mixture.

What is a solution? What is a suspension?

Pick two answers.

• Solution:

  When ingredients are visible

• Solution: When two or more materials are combined to create one

• Suspension: When ingredients aren’t visible

• Suspension: When two or more materials are combined, but do not create one

What is a precipitate?

• When a solid product is formed from a mixture

• When a liquid is turned a different colour

• When a gas has formed and the mixture evaporates quickly

• None

What is a homogenous mixture? What is a heterogenous mixture?

• Homogenous mixtures are when the ingredients are mixed well

• Homogenous mixtures are when the ingredients are stirred

• Heterogenous mixtures are when the ingredients are visible

• Heterogenous mixtures are when the ingredients are mixed well

When a liquid turns to a gas, it is called…..

• Condensation

• Evaporation

• Melting point

• Freezing point

When you mix two or more substances together, we create a

• Solution

• Suspension

• Chemical reaction

• Mixture

What are clues of a chemical reaction?

• Energy, heat, melting, smelling

• Energy release, gas formation, precipitates, colour change

• Precipitate, release, heat, drinking

• None
