Way forward

  The way forward for any society is their involvement in science education focusing on producing scientific literate graduates/ individuals. According to George E.D (2000) scientific literacy can be defined as follows: The goals for science education are all inclusive and formidable; scientific literacy means that a person can ask, or determine answers to questions derived from curiosity about everyday experiences.

I illustrated the relationship between the moon, sun and the earth with these items; a torch light, an orange, water melon, plywood board, a sharp edge stick, all placed on a table serving as the base.

I pierced the water melon (representing the earth)with the stick, holding the stick edge beneath the melon(as the axis) and twist it to turn round to show how the earth rotate then switch on the torchlight to serve as the sun light. I also move the melon on its axis around the light source to show how the earth orbits round the sun. The process was repeated with an orange (representing the moon) placed in between the light source and the melon (earth) in half, full demonstrating how eclipses are formed.

Natural Disaster

Natural disasters is any catastrophic event resulting from natural phenomenon of the Earth; examples include floods, wild fire,  hurricanes, tornadoesvolcanic eruptionsearthquakestsunamis, and other geologic processes.

A natural disaster causes some economic damage in its wake and also loss of life or property which naturally leaves the sternness of which depends on the affected population’s spirit or ability to recover and also on the infrastructure available. We should be watchful, careful in doing things so that we do not cause  disaster like fire in our surroundings. Continue reading


There are factors that contribute to the risk of collision, including vehicle design, speed of the operation, road design, road types and the driver skill, diver behavoir, notably speeding and street racing.  Collision is short – duration interaction between two bodies or more than two bodies simultaneously causing change in motion of bodies involved due to internal forces. The magnitude of the velocity difference at impact is called the closing velocity


To carry out this experiment; I set out two tables, the first had smooth surface and the second surface is rough (I poured sand on the table). I also used the toy cars, marbles of two different sizes and rings.

Heat Transfer Experiment.

Heat is a measure of the internal energy that has been absorbed or transferred from one body to another.

The metric unit of heat is called the calorie (cal.). A calorie is defined as the amount of energy needed to increase the temperature of one gram of water one degree Celsius.

Heat transfer that takes place because of temperature difference takes place in three different ways; conduction, convention and radiation.

Heat transfer takes place in solid as Conduction from a warmer place to a cooler one. Solid vibrate in a fixed equilibrium position and that molecule in a higher temperature region have more kinetic energy than those in a lower temperature region.

Convection is the transfer of heat by a large-scale displacement of groups of molecules with relatively higher kinetic energy. Molecules with a higher kinetic energy are moved from one place to another place.

Radiation involves radiant energy that moves through space. Radiant energy includes visible light and many other forms.

Materials that contain many small air spaces are good insulators, on the hand materials that contain many small air spaces are poor conductors because air molecules are far apart.

To find out which material will be a conductor and insulators of heat, the following materials were used to carry out the experiment.

  • Hot water
  • Simple thermometer
  • 5 rubber bands
  • 5 identical mugs
  • 5 test materials: cotton cloth, polyethene bag (nylon), serviettes, wood and foil.

All five identical mugs were placed on a table, and poured hot water of the same quantity in to them. Each surface was covered with one of these materials. They were allowed to stand, and the alarm set for 30 minutes, there after the temperature of each content was tested with a thermometer to measure the hotness of the liquid.  These are the results of the test;

S/N Material Temperature (C)
1 Polyethene (nylon) 54
2 Serviette 45
3 Cotton cloth 48
4 Wool cloth 52
5 Foil 48


The mug surface covered with polyethene (nylon) material record the highest temperature while serviette records the lowest temperature.

This is the order of increase; Serviette (45), cotton cloth (48), foil (48), wool cloth (52), and polyethene (nylon) (54). The material that helps to stop heat from escaping are good insulator while materials that allows heat to escape are good conductor.

Therefore polyethene (nylon) is a good insulator while serviette is a good conductor.

Transportation system in Nigeria


Nigerian Airways

my lesson plan for week five was on the transportation system in Nigeria.  the class was  interactive, educative and informative. The students mentioned the types of transportation system in Nigeria and their routs. we also discussed the advantages of transport different road types in Nigeria; Federal road, State road and Local Government road. I gave the students an assignment; to choose the fastest transportation system and make a model of it.

They all agree that  plane is the fastest but they argues on the types and shapes. I attached some pictures of my students work. This particular student argues that the Nigeria airways is the fastest because of its shape.

Iceberg Experiment!

Global warming is an increase in the earth’s atmospheric and oceanic temperatures due to increase in the green house effect resulting from pollution (Merrian-webster,2009).

Green house effect is the gradual depletion of the ozone layer by pollution; flaring of gases from industries, open burning of agricultural materials, gases from the exhaust pipes, dumping of refuge indiscriminately.

Lesson plan is an ideal tool for teaching. It is the teacher’s guide in the class room while teaching. It keeps the teacher focus and direct on the subject and topic to be thought.

Planning a lesson, one has to consider the time frame it will take him/she to teacher that particular topic. The curriculum has to be sub-divided to syllabus main for each level / class and then scheme of work for each term or session.


There are different format of planning a lesson, but in the context the 5 E’s method is adapted. The 5E’s method talks about Engaging the students in a discussion or interactive class, allowing the students to Explore by wondering and questioning. Explanation of the concept to the students by defining key terminology or demonstrating the concept. Elaboration of the topic is done by providing useful life application and evaluation of the students by questioning or assignment. Continue reading
