Read out the statements below. Students decide whether the statement is true or false. They indicate their answer in the following way:

False

Don’t know True

Sit down Stand up Stand up with arms in the air

Or they can always use traffic light cards! After each question, ask a selection of students to explain the reasons for their answer. After hearing several reasons, give the students the opportunity to change their answer. 1. The mole is a unit.

T

2. The mole is a mass. 3. One mole of water (H2O) and one mole of glucose (C6H12O6) have the same mass. 4. One mole of H2 contains the same number of molecules as one mole of CO2. 5. One mole of H2 contains the same number of atoms as one mole of CO2. 6. There are more atoms in 12 g of carbon than in 12 g of copper. 7. A mole is a molecule. 8. The mole is a number. 9. One mole of a substance contains Avogadro’s number of elementary entities. 10. One mole of a substance contains 6.02 x 1023 elementary entities. 11. The amount of substance is measured in kilograms. 12. The amount of substance is a volume. 13. I understand what a mole is.

The words on the cards below are important in understanding the definition of the mole. Cut out the cards.

Game 1 Hold a card above the head of a volunteer. The volunteer can ask for clues from anyone in the class, and must keep asking until they guess the correct word above their head.

Game 2 A variation is to ask the student with the card above their head to ask questions until they are able to guess the word correctly.

Game 3 Ask a student to select a card. Only they read the card and then describe the idea to the rest of the class, who guess the word on the card. The student who answers correctly rolls a die and counts round the room from themselves to select the next “lucky” student to describe the word on the card.

Option 1 Give one card to each student. They have to find their match, and can help each other. Option 2 Give each team a set of cards. First team to match the definitions up correctly “wins”.

Molar mass

Avogadro’s number

Atomic number

Mole

Relative formula mass

The number of protons you find in the nucleus of an atom.

The constant for the number of entities in one mole: 6.02 x 1023

Mass number

Atomic mass unit

The total number of protons and neutrons you find in the nucleus of an atom.

Atoms which have the same atomic number but different mass number.

Base quantity for which the mole is the unit. It is the number of elementary entities divided by the Avogadro constant.

The ratio of the average mass of the atom to the unified atomic mass unit

Ratio of the mass of a molecule to the unified atomic mass unit. Sometimes called the molecular weight or relative molar mass.

One twelfth of the mass of carbon-12.
