II.Subject Matter:

Insecticides and Pesticides


Insecticide is a chemical poison used to kill harmful insects at home, such as cockroaches and mosquitoes. It is applied with the use of spray guns and aerosol bombs.

There are three basic types of insecticides, namely: phosphates (malathion), carbomates, and DDT ( dichlorodiphenyltrichlorothane)

Pesticide is a poison used in farms to effectively control pests such as stemborers. The use of pesticide improves the yield of crops such as rice, corn, and sugarcane.

Pesticide is grouped into three, namely: herbicide, insecticide, and fungicide. Herbicide kills harmful weeds. Insecticides destroy harmful insects in plants. Fungicide destroys fungi.

I.Objective:

Measure velocity of a moving object.


Velocity


The other way of describing motion is by its velocity. Speed (S) and velocity (V) both describe the rate of motion of an object. The difference is that the velocity has a specified direction while the speed has none. Because of this specific direction, the distance measured in calculating velocity is not the actual distance covered by the body, if the body were going in different directions. What is measured is its displacement. Displacement differs in distance in that distance refers to the total path traveled by the moving body from starting point to terminal point.

A frame of reference is to what an observer compares the position of an object.

When two forces are exerted upon a body, such that a net force results from their interaction, the system of forces is said to be unbalanced.

When two or more forces are applied simultaneously on a body such that there is no net force acting on it, the system of forces is said to be balanced or in equilibrium.

A body at rest is acted upon by a balanced system of forces.

Cite examples on how heat energy can be transferred.

Ask how do they know that an object has moved.


1.Motivation:

If you are going to observe the wall clock, why is it easy to say that the second hand of a clock is moving?

2.Presentation:

Activity

a.Show figure 6.3a and 6.3b.

b.Observe figure 6.3a and 6.3b

c. Infer which of the animals moved.

d.Observe and infer

- It there any change in the position of the animals?

- What can you infer from this observation?

- Can you tell for sure which of the two animals moved? Why?


The class can tell which objects moved. Ask how do they know that an object moved.

Give the difference between balanced and unbalance forces.

4.Application:

Before judging things on people around you, what would you do?

IV.Evaluation:

Choose the correct answer.1.How do you know that an object has moved?

a.There is a change in an object's weight.

b.There is a change in an object's size.

c.There is a change in an object's position.

d.There is a change in an object's texture.

2.An observer said the bus has moved. He viewed the bus with respect to another object, we call this hisa.starting point

b.frame of reference

c.way of measurement

d.estimation

3.Newton's first law of motion states that a moving body will maintain its motion

a.and gain acceleration.

b.but will gradually slow down because of friction.

c.along a circular path and with constant acceleration.

d.unless acted upon by an outside force.

V.Assignment:

Make a list of things, objects or bodies around you which are being acted upon bya. balance forces

b. unbalanced forces

Date: ____________

I.Objective:

Observe that a body at rest tends to remain at re;t and a body in motion tends to be in motions unless an outside force is applied on it

Values:Handling materials with care; respect for others

II.Subject Matter:

Mechanical Energy Formation and Uses


A body will not move unless acted upon by a force and when it is set into motion, it will continue moving unless stopped' by a force, which is called inertia or a body's resistance to acceleration.

Mass is a factor that affects a body's acceleration

The greater is the mass of a bodys the greater is its inertia, and therefore the lesser is its acceleration.

It is easier to accelerate or decelerate a body with less mass than a body with a greater mass.

List of things, objects or bodies which are acted upon by balanced/unbalanced forces.

Ask how 60 they know that. objects have moved/which objects moved.


1.Motivation:

Put a ball on the table, let it remain at rest. Ask them if the ball moves. Let it roll, ask if it continues roiling. Let it roll once again, then, put a stick on its way, what happen?

2.Presentation:

Activity:

a.Suspend two plastic cups with equally long strings. Fill one plastic cup with sand. b.Use the drinking straw to blow against the plastic cups to set them in motion.

b.Observe and infer.

-Which plastic cup has more mass? Which plastic cup has more inertia?

-What can you infer from these observation?

-Why is weight not a factor to be considered in moving each plastic cup?


Explains what inertia is.

Tell the factor that affects acceleration.
