COURSE POLICIES

A. General Guidelines

1. There are eleven experiments, with each experiment to be completed in one class meeting. In case classes are suspended for any valid reason, the schedule of experiments shall be moved by an amount equal to that which is lost due to the suspension.

2. There is a corresponding manual for each experiment. The manual consists of six parts: prelab activity; introduction; materials; procedure; data sheet; and questions.

3. All experimental procedures are performed by group, except for the Measurement, Uncertainty, and Deviation experiment which must be done individually. Each group consists of three members. Members of the group are expected to read all parts of the manual before coming to class. The Instructor can demand the group to repeat all procedures if the experiment is not conducted properly. However, no extension will be granted if the experiment is not finished on time due to members negligence.

4. Each student must have a copy of the manual on the scheduled experiment. 5. There is one practical examination at the end of all experiments to test the understanding of

each student about the course. 6. Absences are considered excused only if there is a valid reason. Valid reasons include but are

not limited to the following: illness, death in the immediate family, or official UP duty. The student should present on the first lab meeting he/she is able to come back, a medical certificate from the UP Health Service in case of illness or a letter from a parent/guardian in case of a family members death or an official endorsement in case of official UP duty.

7. University rules apply for cheating. Any form of cheating in examinations or any act of dishonesty in relation to studies, such as plagiarism, shall be subject to disciplinary action.

B. Laboratory Protocol

1. Materials for each experiment are borrowed in room F107. Each group must leave one members identification card (ID) and a list of all the members when borrowing materials.

2. Materials for each experiment must be handled with care at all times. Putting specific marks (permanent or not) on certain materials are strictly prohibited.

3. Each member of the group is responsible for knowing the proper operation of any apparatus/equipment assigned to his/her group. If one of the group members damaged or defaced any apparatus/equipment, the entire group shall be liable for the corresponding repair, or in case of irreparable damage, shall replace the apparatus. Failure to do so will be grounds for ineligibility to enroll in the next semester(s).

4. Cleanliness must be maintained in the designated group table. All unnecessary things (e.g. bags, personal items, etc.) must be placed inside the cabinet located in the room.

5. All borrowed materials must be properly returned in room F107 after use. 6. Eating, drinking, smoking, and horse playing inside the laboratory are forbidden. The elementary laboratories are

equipped with CCTV cameras. Anyone caught behaving inappropriately shall immediately be subjected to disciplinary actions.

C. Prelab Activity Guidelines

1. The prelab activity must be accomplished individually before the scheduled experiment. 2. The prelab activity is due right before the start of the corresponding experiment. 3. A student who failed to submit the prelab activity before the start of experiment will automatically get zero.

D. List of Activities and Experiments

EXPERIMENTS Objectives

Measurement, Uncertainty, and

Deviation

Determine the uncertainty of measured or calculated data from observables. Report correctly the measured or calculated data. Determine if the measured data is acceptable.

Addition of Vectors Show that the sum of forces acting on a system in static equilibrium is zero. Obtain the equilibrant of two or more forces. Obtain the orthogonal components of a force.

Measuring Devices

Determine the least count and uncertainty of different measuring devices. Measure the dimensions of an object using a ruler, a Vernier caliper, and a micrometer caliper. Measure the mass of an object using a weighing scale. Calculate the density of different materials.

Free Fall Measure the acceleration of a freely falling body, g, to better than 0.5% precision using a

Picket Fence and a Photogate. Use graphical analysis to calculate the acceleration of a free falling body.

Projectile Motion

Verify that in projectile motion, horizontal and vertical motions are independent of each other. Measure the launch speed of a ball using a Vernier Projectile Launcher Apply concepts from two-dimensional kinematics to predict the impact point of a ball in

projectile motion. Take into account trial-to-trial variations in the speed measurement when calculating the

impact point.

Physical Pendulum Determine the moment of inertia of a cylinder Obtain the period of oscillation of a physical pendulum

Rotation Calculate the net torque for a disk that is rotating horizontally about its center. Calculate the net work done on a disk that is rotating horizontally about its center. Verify the conservation of energy and angular momentum for a rotating disk.

Sound

Measure how long it takes sound to travel down and back in a long tube. Determine the speed of sound experimentally and compare it with accepted value. Measure the frequency and period of sound waves from tuning forks. Measure the beat frequency produced by the sound from two tuning forks.

Torque and Equilibrium

Calculate and add torques applied on a rigid body. Use the concept of equilibrium in determining unknown masses. Construct a simple beam balance to measure the mass of small objects.

Buoyancy Obtain the density of fluids using the buoyant force experienced by an object computed using

its apparent weight while suspended in air and in water. Calculate the density of irregularly shaped solid objects using the buoyant force.

Friction*

Differentiate the coefficient of static friction from the coefficient of kinetic friction. Obtainthe coefficient of friction via two methods. Determine the dependence of the coefficient of friction to the type of materials and the area of

contact. Marked by (*) means the experiment will only be done if time permits.

E. Schedule of Experiments Due to limited number of apparatus/equipment, parallel sections cannot perform the same experiment on the same day. Below is the list of experiments according to the laboratory room:

Measurement, Uncertainty, and Deviation worksheet shall be done individually.

F. Worksheet Guidelines 1. Raw data, calculations and analysis must be legibly written in the worksheets. Erasures should be minimized. 2. Raw data and most calculations are checked at the end of every meeting. The Instructor can demand the group to

repeat all procedures if raw data are erroneous or largely deviates with the expected results. 3. The worksheet grades (60%) will come from the data (40%) and the analysis questions (20%). The grades may be

adjusted by the results of peer-evaluation. 4. Fabrication of experimental data/results and copying another persons worksheet (except for raw data, in the case of

group activity) is strictly prohibited. Anyone caught violating this rule shall immediately be subjected to disciplinary actions.

5. Worksheets are due before the start of every experiment. A group may not start a new experiment until the worksheet for the previous one is submitted. Worksheets submitted after the official class time will be considered late. Late worksheets will receive a 50% deduction for every week late.

6. All prelab activities and data and worksheets must be returned to the Instructor on the day of the practical examination. Students who will not surrender all their prelab activities and worksheets will be given a grade of INC.

G. Practical Examination Guidelines

1. The practical examination is a 27-item multiple-choice type of exam conducted during class hours a week before the end of classes.

2. The practical exam consists of 9 different stations. A student is given 6 minutes to answer all questions per station. 3. Each station consists of 3 questions regarding certain experiments. Each question has 4 possible choices and can be

answered by following the instructions stated in each station. 4. Instructions in each station are not limited to procedures introduced in class. It may be a modification of experiments

performed in class or it may be an entirely new experiment that is not performed in class but directly applies the concepts/skills learned in class.

H. Grading System

1. A student is given a grade of 5.0 if the accumulated absences reach three (20%), at least two of which are unexcused.

For the case of three absences, 2 of which are excused, the student is advised to drop the course. It is the responsibility of the student to undergo the dropping procedure. If the student misses the deadline of dropping upon being advised, he/she will be given a grade of 5.0.

2. A student who missed an experiment due to valid reason(s) will be given a make-up experiment only after he/she presents a valid excuse slip/letter on the first lab meeting he/she is able to come back. Make-up experiments should be done during the day scheduled for Assessment and Reflection.

3. A student who missed an experiment and its corresponding make-up will automatically be given a grade zero for that experiment.

4. A student who missed an experiment without valid reason(s) will automatically be given a grade of zero for that experiment.

5. A student who missed the practical exam due to valid reason(s) can take a make-up practical exam. If the student missed the make-up practical exam, he/she will be given a grade of INC only if his/her class standing (assuming a zero score in the departmental exam) is at least 4.0.

6. A grade of INC can be removed by completing the missed requirement within one academic year. A student must be enrolled during the semester he/she completes the missed requirement. The grade of INC will be converted to a numerical final grade upon re-calculation of the grade including the requirements completed.

7. The Instructor will only give a grade of DRP upon the students completion of the dropping module. 8. A student granted a leave of absence (LOA) would only be given a grade of either DRP or 5.0. A grade of 5.0 is given if

the LOA is granted after of the semester has lapsed and the student's standing is failing; otherwise DRP is given. 9. The student must re-take the course when a grade of 4.0 is incurred. There is NO removal exam.

I. Student Conduct and discipline

1. Observe courtesy during class hours and exams by putting all electronic devices into silent mode. Using unnecessary electronic devices inside the laboratory is not allowed.

2. Any form of vandalism is strictly prohibited in the NIP building. A student who is found guilty shall immediately be subjected to disciplinary actions.

3. CCTV cameras are set-up at different places inside and outside the NIP building that monitors and records any untoward incidents 24/7.

4. Wear your IDs at all times inside the premises of NIP.
