Project goals.

1.Science Students will find out the type of chemicals (paints) used in the writing
2.graphic students will look at the writing.
3.math students will look at the positions and angles of the posts 
4.English students will look at the grammer and the language used.

Subject : Science    Grade level   17  -  18yrs

Lesson goals
At the end of the lesson , students should be able to know about 
a. the following chemicals.
1. water base paints  2.oil based paints 3. acrylic paints
b. use the computer to compute data.

Lesson content objectives:
water base paints - uses water for mixing or dissolving the paint 
      oil based paints -  uses organic solvent in dissolving the paint 
     acrylic paints   - uses neither of the above 
 computer -  use the computer to find percentages

Performance objectives
observe and record the type of paint
use excel to find percentages

Technology objectives:
Application of excel in computing

Instructional activity (teacher component)
Coordinate the formulation of the questionnaire to be used by the students

Questionnaire
Type of paint used
water base   oil based  acrylic

paint colour background contrast 
white         black   green   red    yellow   others

paint colour foregrounds contrast

are some paints faded ?     yes            no

are some paints scraped off ? yes        no

are some paints washed away? yes      no

are the colours used                        deem                   reflective 

what type of materials are used for making the sign post

wood          clay       metal       cement 

Learning Activity (student component )
Students, after going round the locality with the questionnaire,  go to computer laboratory and use excel to compute their data.

Instructional strategies:
In computer room students were put into groups of ten and made to discuss their findings.
Mathematics teacher called in, to help student learn to find averages and percentages using Ms Excel.
Students were given some paint colours to identify in the laboratory

Conclusion
From the observations made by the students, they made the following suggestions in the form of a conclusion:
Most of the artisans use oil base paint which happened to be suitable under the situation .
The background and foreground contrast which is very important in signposting needs attention and improvement.
Most of the paints that had been faded could be attributed to the position (direction) of the post. Some were erected to  face the Sun rays directly and others were almost at right angle to the rays.
Most of the paints that were scraped  away was attributed to their height- either too short to be tempered  by pedestrians or too long, close to an object.
In all, Signposts in the area help the industries to achieve their ultimate goals; with a little alterations, the post can be more beneficial.
A few of the posts were causing nuisance and was due to the crowded posts around these areas.
