Assignment 3:
Name: Preciosa Valledor Cabrera
School: Ismael Mathay Sr. High School
Part 1: Review the CDs (Schoolnet 1 and 2) and fill up the following table.
a. Select 10 Learning objects (LO) based on your teaching subject. For each learning object,
explore it and try out the activities associated with it. After that, fill in the table below.
Title of LO
Useful
or not
useful
useful
If useful, describe an activity
how you can use it
The concept of
covalent bonding is
discussed through the
use of an interesting
and engaging analogy.
The discovery of
electrons by using
cathode ray tube and
what atom is made
are discussed through
animation.
The properties and
changes of matter
were discussed.
useful
Chemical bonding, Students will
have fun watching and learning
the concept of covalent bond.
useful
Subatomic particles. This can be
used to show how cathode ray
tube is used to discover electron,
one of the subatomic particles.
useful
5. Size of Particles
The effects of size of
particles on the rate of
reaction and to give
reasons why it is so.
useful
6.
Chromatography is
applied to separate
and identify the
components of
mixture.
useful
The ideas on the
existence of atoms
arise from the
evidences gathered by
early philosophers led
by Democritus.
useful
Properties of matter are very
important to understand the
changes matter undergo.
Factors affecting the rate of
reaction. Can be used to predict
the effect of dividing the
reactants into smaller pieces to
the rate of reaction.
Separation of the components of
mixtures. Chromatography is
used to separate and identify
the components of a
homogeneous mixture.
Atoms: The smallest particle.
Describe the nature of atom
1.
Electrolysis
2. Covalent bond
3. Discovery of
Electrons
4. Properties of
Matter
Chromatography
7. Evidence for
Atoms
Short description
Electrolysis takes place
when electric current is
passed through a
conducting solution that
causes the
decomposition of the
substance.
Chemical separation of a
compound, like water, producing
hydrogen and oxygen. The gases
produced can also be tested.
8. Acids Bases and
Indicators
The reaction of acids and
bases are discussed in
this learning object.
useful
9. Atomic Models
Images of atomic
models, subatomic
particles scientists
who proposed the
atomic models
Equilibrium can be
disturbed by different
factors such as
temperature and
concentration of
substances.
useful
10. Equilibrium
useful
Reaction of acids and bases.
Testing substances as acids or
bases using an indicator.
Atomic models and subatomic
particles.
Reversible and Irreversible
reactions. State of balance can
be disturbed by changing any of
the factors, like temperature,
pressure and others.
Part 2:
Select ONE of the LO and design a class activity for that. Write a lesson plan on how you are going to
teach the class with the LO. You should design an activity sheet to accompany the LO. You can
assume that you have a notebook computer and a projection system in your class.
Deadline: 30 October 2009. Upload this into the wiki in the subject resource page. Also, do a link
from your own wiki page.
