Hot Goes Up Cold Goes Down

Learning Outcomes

1. Students will be able to understand the process of convection.
2. Students will be able to describe the movement of heated particles of liquids and gases during heat transfer through convection mode.
3. Students will also be able to cite example of the transfer of heat through convection.

Description Of Activity

How to play

1. Students will be dived into two teams  A and B
   Team A - Will include the teacher, a student called cooling agent (CA) and another student called as heating agent(HA).
2. Team B  - All the students of the class except the cooling and the heating agent will act as liquid/gas particles and constitute  the team B.
3. 2. The play ground will be divided into two parts I and II with a line or an arc.
4. 3. All the liquid particles will run in the portion II of the ground. The cooling agent will chase and try to catch hold of these particles.
5. 4. As soon as a liquid particle is touched by the cooling agent (CA), it will go and sit down on the line dividing the portion I and II of the ground.[The CA will announce :- "cool goes down"]
6. The liquid particle are now cool and will move only in sitting position.They will now start moving towards the heating agent (HA) by taking frog leaps.
7. 5. When the cool liquid particles reach the HA and touch it, they will again stand up. [The HA will announce :-"Hot goes up"]
8. 6. The liquid particles now run  and join the other liquid particles in portion II of the ground Here again they will be chased by the CA and the game will go on.
9. As the game is announced to be over, if the no. of students standing in portion II of the ground is more than the no. of students sitting / frog leaping in portion I of the ground; Team B wins. However of the no. of students sitting on the portion I of the ground outnumber those students who are running in portion II, Team A wins.

 

Variations

1. The heating agent need not necessarily has to be a student. A chair/ a pole or any other object can be labelled as heating agent.
2. There can be more than one heating and cooling agents in the game.

Coaching Tips

1. The liquid particles have to run within the boundary of portion II of the playfield. They will try to avoid being caught by the Cooling Agent(CA).
2. While in portion I of the playfield, the particles will try to reach the Heating Agent (HA) as fast as possible.

Equipment/Material Required

No special equipment required.The ground can be appropriately marked for the game.
