Thermometer – Procedure

Agrupamento de Escolas de Oliveira do Bairro - PORTUGAL

The bottle is handed to a

random person who should

measure and pass it on to the

person sitting on his/her right

saying his/her name.

Initial Temperature

Thermometer – Procedure

The second person should shake the bottle

(5 seconds) say his/her name and pass it on.

This process continues until the last person.

At the end the temperature is measured.

MathematicsMathematics

Step 1: Write a 3 digit number ( all numbers

must be different and not palindrome).

Step 2: Write the reverse of that number.

Step 3: Subtract it from the initial number.

Step 4: Write the reverse of the result.

Step 5: Add it to the result of the subtraction.

TemperatureTemperature is

the measure of

the kinetic energy

level within an

object, system or

body.

Kinetic Energy Kinetic Energy (energy related to movement)

• Inside the bottle we have our lead balls.• When you shake the bottle, balls will move much faster so

its kinetic energy is greater. • Moving faster there will be more clashes between them

resulting in more heat. • We measure this heat through collisions between particles

inside the bottle and at the end by measuring the thermometer that will register a higher value.

Why this theme?

Science Technology Society

The increase of world energy consumption, results from our increasing needs for comfort and well-being.

From a broader standpoint the scientific competence represent what people know, do and value most in your life.
