The Year 2011 is a challenging year for the National Science Teaching Instrumentation Center (NSTIC) because it was able to accomplish various tasks that were more demanding in terms of knowledge, expertise and time. Aside from the regular programs, the Center was also successful in implementing a big project on “Mass Production and Supply and Delivery of Science Equipment to the selected Public Secondary Schools Nationwide”. To ensure that the delivered equipment will be fully utilized and will last longer than expected, it conducted a nationwide Training Workshop on the Use and Care of Science Equipment to the recipient public secondary science teachers, division and regional science supervisors.
This annual report is an accounting of the accomplishments on the implementation of the CY 2011 programs, projects and activities of NSTIC. To make this report more presentable, informative and easy to interpret, graphical presentation of the data and some pictorials were included.
The major programs of NSTIC based on its mandate in the Executive Order No. 112 are the following: a) Science Equipment Development Program (Prototyping of Science Equipment and the preparation of the corresponding manuals); b) Training of science teachers; c) Preparation of training manuals; and d) Project implementation on projects related to science and mathematics equipment.
The detailed information of the CY 2011 Operation of the National Science Teaching Instrumentation Center are as follows:
- I.SCIENCE EQUIPMENT DEVELOPMENT PROGRAM (PROTOTYPING)
This program aims to develop science equipment prototypes of acceptable quality that will adapt to the locally available materials and technology so that it could be mass produced in our country at an affordable and reasonable cost. Another purpose of prototyping is to improve the functionality and quality of the existing science equipment in the market and reduce the production cost. There are two types of science equipment prototypes developed by NSTIC namely: a) standard science equipment – it is produce using production equipment and tools; precise and accurate and for experiments that are quantitative in nature; and have longer life; b) improvised science equipment – it is a simplified version of the standard science equipment that can be constructed by the science teachers or the students applying the concept of Do-It-Yourself (DIY) and uses common materials for household, office, etc and even the recycled items. It will be manufactured by the science teachers or the students using common household hand tools; it is low cost; and generally use for qualitative experiments.
The following science equipment prototype were processed in 2011
- A.STANDARD SCIENCE EQUIPMENT
- a)Integrated Science (Science I) – There are five standard science equipment undergoing development namely:
- 1.Earthquake Simulator – is used to simulate the seismic or earthshaking usually caused by earthquake or bombThis model could simulate the horizontal and vertical seismic movement while most of those available commercially could only simulate the horizontal movement. The development status is 86% in process and in-house try-out or testing is ongoing.
- 3.Seismograph – an apparatus use to measure and record the vibration within the earth and of the ground. The prototype could measure and record the horizontal and vertical vibration. The development status is 86% in process and in-house try out is ongoing.
- a)Integrated Science (Science I) – There are five standard science equipment undergoing development namely:
- b)Biology (Science II) – There is only one standard science equipment undergoingnamely:

This self-contained unit allows students to observe angles of reflection, refraction and complete internal reflection for a light ray that passes through two clear media. The development status is 100% completed, however, design improvement is necessary to correct minor deficiencies with regards to the functionality.
- 2.Optics Kit Case – A hard storage case with soft cavities (made of foam) to keep and protect the delicate lenses and other items from scratch, making it safe, organize and ready for use. The development status is 100% completed, minor changes on the design of the foam compartment is necessary for the convenience of the user and total protection of the optical elements.
- 3.Electronic Sound Source – An electronic device when connected to a speaker create audible sound without the need of a connected acoustic transducer (mic, pick up, or recorded signal). This device is an accessory of a resonance apparatus which is limited to only 2-preset frequencies in sine waveform and powered by a 9 volt dry cell battery. The development status is 85% in process. The electronic circuit needs to be redesign to improve the sound output.
- 4.Sound Resonance Apparatus – Is composed of outer and inner tubes. The inner tube serves as piston to vary the air column inside the outer tube. This is used with electronic sound source to observe the resonance phenomenon in an open ended cylindrical tube and to determine the velocity of sound in air at a given temperature. The development status is 100% completed and ready for presentation to the NSTIC MANCOM Sub-Technical Committee who will do the final evaluation and critiquing before declaring the science equipment ready for mass production. This committee is composed of experts from DepEd BSE and DOST ITDI and SEI.
B. IMPROVISED SCIENCE EQUIPMENT
- a)Integrated Science (Science I) – There are four improvised science equipment developed namely:
- 1.Momentum Conservation – An improvised apparatus that utilizes two or more discarded plastic bottles suspended on a horizontal nylon string that can put into motion or collision without falling. This low cost apparatus allows the students to observe the momentum conservation phenomenon. The development status is 100% completed and for manual writing prior to introduction to the field.
- 2.Soot less Kerosene Burner – The development as improvised equipment is 100% completed, however, NSTIC decided to elevate it as standard equipment for better functionality and longer life. This equipment is necessary especially in far flung areas wherein the supply of denatured alcohol is very limited or none at all and only kerosene is readily available. This equipment will improve the combustion and performance of a kerosene fuelled lamp and eliminate the soot emitted due to incomplete combustion. It will generate a flame equivalent to denatured alcohol fuelled lamp.
- 3.Atmospheric Pressure Measuring Device – Low cost improvised equipment made of discarded plastic bottles, colored water and transparent plastic tube. Without calibration it function as water baroscope that only detects rather than measure the changes of atmospheric pressure indicated by the rising and falling of water column inside the plastic tube. The development is 100% completed and for manual writing prior to the introduction to the field.
