Teacher’s notes This presentation contains a sequence of four statements designed to allow students to narrow down the identity of a mystery element. Students will need to rely on their knowledge of chemistry to identify the element. Make sure that the room is free of trip hazards. Arrange the tables so that there are five ‘islands’. Each island needs to have a large card with the name of one of the following elements on it: hydrogen, carbon, iron, neon and magnesium. Each statement eliminates one of the elements. Students standing at a particular element when it is eliminated are out of the game and must sit down. By responding correctly to each statement, students should arrive at the correct final island.

What element am I?Teacher’s notes
This presentation contains a sequence of four statements designed to allow students to narrow down the identity of a mystery element. Students will need to rely on their knowledge of chemistry to identify the element.
Make sure that the room is free of trip hazards. Arrange the tables so that there are five ‘islands’. Each island needs to have a large card with the name of one of the following elements on it: hydrogen, carbon, iron, neon and magnesium.
Each statement eliminates one of the elements. Students standing at a particular element when it is eliminated are out of the game and must sit down.
By responding correctly to each statement, students should arrive at the correct final island.
Ensure that students do not run.

What element am I?
This presentation contains a series of four elements designed to help you narrow down the identity of a mystery element. You will need to rely on your knowledge of chemistry to identify the element.
You will see that the element names have been put in various places around the classroom. After each statement appears on the screen you must go to one of the elements you think could be the mystery element.
Each statement is designed to eliminate one element. If you are standing at a particular element when it is eliminated, you are out of the game and must sit down.
By using your scientific knowledge you should arrive at the correct final element.
Please do not run. It is not a race.

Magnesium Iron Carbon Neon Hydrogen
1. The mystery element reacts with oxygen
Neon does not react with oxygen – so bad lack if you are standing next to neon.

2. The mystery element is not a gas
Unfortunately hydrogen is a gas – so please take a seat if you arestanding next hydrogen.

3. The mystery element has an atomic number between 1 and 15
Oh dear, iron has an atomic number of 26 – bad luck if you are standing next to iron.

4. The mystery element can join with two oxygen atoms to form a notorious greenhouse gas

4. The mystery element can join with two oxygen atoms to form a notorious greenhouse gas Carbon burns in oxygen to form carbon dioxide (CO2) which is indeed a Greenhouse gas. Better luck next time if you picked magnesium.
