Vocabulary Word : Monday
Heat Transfer

Heat transfer describes the exchange of thermal
energy, between physical systems depending on
the temperature and pressure, by dispersing
heat. It may be in the form of conduction,
convection or radiation.

Sentence. Cooking is one way to show heat
transfer.
New Concept : Monday

Energy can be transferred from one system to another
(or from a system to its environment) in different ways:

thermally, when a warmer object is in contact with a
cooler one mechanically, when two objects push or pull
on each other over a distance

electrically, when an electrical source such as a battery
or generator is connected in a complete circuit to an
electrical device

by electromagnetic waves.

TUESDAY ACTIVITY : SPEAKER FOR THE
EYE AND ITS ANATOMY / DISEASES
Vocabulary Word : Wednesday
CONDUCTION

Conduction - to allow heat or electricity to pass through easily by touching or
from particle to particle / VERY COMMON IN SOLIDS

Sentence . When a spoon is placed in a cup of hot soup and the tip of the
spoon becomes hot , this is an example of conduction.

New Concept : Wednesday
 Thermal
energy is transferred through a
material by the collisions of atoms within
the material. Heat flows through materials
or across space from warm objects to
cooler objects, until both objects are at
equilibrium. Heat travels through solids,
primarily by conduction.
Wednesday Activity : CONDUCTION
SAFETY FIRST!

1. The teacher will fill up the styro , plastic and glass containers with HOT water.

2. Be careful when handling HOT water. DO NOT PLAY OR IMMERSE YOUR HAND!

3. Take the temperature of water in the plastic, glass and Styrofoam containers
using the thermometer. Read after 1 minute.

4. Immerse the metallic objects in the styro and plastic containers and feel the
heat as it travels on the spoon or tweezers.

5. Immerse the wooden stick and ruler in the plastic container. Notice if the heat
will travel or conducted too.

6. What is is conduction? Which materials conducted heat ? Which materials did
not conduct heat at all? Which container held much heat? Is it the plastic,
Styrofoam or glass? What do you call those materials?
Vocabulary Word : Thursday
CONVECTION

Convection is the transfer of heat through a fluid ; heat circulation

is the transfer of heat from one place to another by the movement of fluids,
very common in liquids and gases
Convection is the transfer of heat by the actual movement of the heated
material.
Sentence . Boiling is an example of convection.
New Concept : Thursday

Heat is circulated in fluids, both liquids and
gases, through the process of convection.
Radiation is energy that travels across distances
in the form of electromagnetic waves. Over time,
thermal energy tends to spread out through a
material and from one material to another if they
are in contact (conduction). Thermal energy can
also be transferred by means of currents in air,
water, or other fluids (convection).
VOCABULARY WORD : FRIDAY
RADIATION

Electromagnetic waves that directly transport ENERGY through space.
Sunlight is a form of radiation that is radiated through space to our planet
without the aid of fluids or solids.
NCFE QUESTION : Thursday

If you placed a hot stone in a beaker of cold water, what
would happen to stone and water after 10 minutes of time
elapsed?

a. The stone would get warmer and the water would get
cooler.

b. The stone will get as cold as the water had been.

c. The water would get as hot as the stone had been.

d. The stone would get cooler and the water would get
warmer.
