PROBLEM SOLVING METHOD

What is problem-solving?

Students are presented with problems which require them to find either a scientific or technological solution.

It is a student-centered strategy which require students to become active participants in the learning process.

Problem solving is a teaching strategy that employs the scientific method in searching for information.

This approach is used most often in science and mathematics classes. The students are trained to be sensitive to any puzzling situation or to any difficult situation that needs to be solved. Having defined the problem clearly, a tentative solution is solicited.

The closest scientific guess is then pursued by undertaking an appropriative investigative technique such as performing an experiment or gathering data through directed observations. Finally they are led to formulate conclusions.

EGG-CITING EXPERIMENT

Materials:1 raw egg1 piece of newspaper1m string1m sticky tape

!!!Do not add nor subtract anything from these materials.

Procedure:

Design a container that will protect the raw egg from breaking when dropped from a height of 10 m.

GUIDE QUESTIONS:1. Did your egg break? Why or why not?

2. How many feet were you able to drop your egg before it broke?

3. What would make one object have more air resistance than another?

4. Why would something not break if it fell on a pillow as compared to the bare floor?

FORCES

- is any interaction which tends to change the motion of an object.

- Can also be described by intuitive concepts such as force or pull.

GRAVITY

- Is a force that tends to pull objects towards the center of the earth.

DRAG/ AIR RESISTANCE- is the forces that are in opposition to the relative motion of an object through the air
