New Rubrics in Performing Laboratory Activity

Grading Rubrics for Lab Work

Score	Level	Description
Safety
4	Advance	Obeys all safety rules all of the time; a model of safety behavior; encourages others to be safe.
3	Proficient	Obeys all critical safety rules
2	Basic	May require an occasional reminder during perceived non-critical moments to obey safety rules; does not fool around; obeys most chemical and equipment rules
1	Novice	Consistent not following safety rules; endangers self and others
Participation / Effort
4	Advance	Efficiently utilizes all class time; professional work habits; completes lab
3	Proficient	Utilizes class time constructively; completes lab.
2	Basic	Stays on task most of the time; may or may not complete lab time allotted
1	Novice	Needs consistent monitoring to stay on task; may or may not complete lab
Data Collection/Observation
4	Advance	Actively shares idea; observation, and answers in each question in the activity; follows all the procedures in conducting experiments and recording observations; observations are exemplary; helps in identifying errors in data gathered
3	Proficient	Observations are adequate though more could have been recorded. Instruments have been read to limits and all units have been recorded. Sources of error and effect on data have been recorded
2	Basic	Critical data needed to meet basic lab objectives has been collected. May not have used correct format or followed all guidelines in expectations. Attempts to identify sources of error and effect on data
1	Novice	Critical data needed to meet basic objectives is missing. No attempt to identify sources of errors.
Techniques
4	Advance	Uses all equipment properly. Procedure taken and decisions made during experiment exemplify chemical literacy. Techniques employed insure accurate data collection
3	Proficient	Uses all equipment properly. Procedure taken and decisions made during experiment indicate good chemical literacy. Techniques used allow for accurate data collection
2	Basic	Most equipment is used properly. Techniques may lead to inaccurate data collection
1	Novice	Misuse equipment. Appears to have minimal understanding of how to conduct experiment
Clean-Up Procedure
4	Advance	Cleans working areas efficiently ( includes table, floor, and sink) ; returns stools and all equipment clean and in their proper places; Helps in cleaning working areas without being told
3	Proficient	Cleans working areas; returns all equipment clean and in their proper places; Helps in cleaning working areas without being told
2	Basic	May require constant reminder in cleaning up procedure
1	Novice	Helping in the cleaning up is inefficient

Second Quarter Activities for Biotechniques

PLANT PRESS

Materials:
Two pcs of plywood, 30cm X 30cm X 1cm
Rubber straps from old bicycle or motorcycle interior tubes

Procedure:
1. Cut the pieces of wood to size.
2. Cut the rubber straps from old interior tires of bicycles or motorcycles.

Illustration:

Notes:
1. Place the plant between several layers of newspapers between the press plates. Wrap the rubber straps around the plates and newspapers to hold them securely.
2. Ropes or heavy strings may be used instead of the rubber straps.

Activity for Biotechniques: Measuring Pollen Size Using a Razor Blade Scores Scale and Microscope

One technique used to determine the size of objects under the microscope is to compare it to an external standard as a razor score scale. This however, is made possible only on straight body tube, monocular microscopes.

OBJECTIVES:
1. To describe pollen grains seen under the microscope.
2. To determine how many times a pollen is magnified under the HPO of the microscope.
3. To illustrate pollen grains as seen under the HPO of the microscope.
4. To measure the size of pollen grains under the microscope using the razor blade scores scale.

MATERIALS:
glass slides
compound microscope
dissecting needle
razor blade scores scale
flowers with pollen grains

PROCEDURE:
1. Dust off some pollen on the surface of the glass slide.

2. Observe under the LPO of the microscope.

Q1. Describe the pollen grains.

3. Then shift to the HPO.
Q2. How many times have these pollen grains been magnified?
Q3. Draw 2 or 3 pollen grains as seen under the HPO. Indicate the magnification.

4. Ussing the dissecting needle, transfer dew pollen grains directly over the razor glade scores scale.

5. Observe the pollen grains under the LPO.
Q4. Describe what you have observed.
Q5. Make an estimated of the size of the specific pollen you are observing.
Q6. If four pollen grains can fit in one scale, What is its estimated size.

Activity for Biotechniques: Making a Razor Blade Scores Scale

In this activity, you will make a scale to measure sizes of objects seen under the microscope.

OBJECTIVES:
1. To use the HPO of the microscope in checking score made by razor blades on TP.
2. To describe the steps in making a razor blade score scale.

MATERIALS:
glass slides
Rubber band transparent tape
razor blades transparency sheet (TP)
Cutting mat or chopping board
scissors / cutter

PROCEDURE
1. Bundle 5 razor blades with rubber band.
2. Place the TP sheet on a cutting mat or chopping board to make scores on the TP sheet with one stroke of the bundle razor blades.
3. Cut out the scored TP sheet about the size of a cover slip.
4. Tape on the sides the scored TP sheet to a glass slide.
5. View under the LPO of the microscope.
6. Are the four spaces even or equidistant to one another? if not repeat 2-4 until you have an equidistant scored sheet.
7. You may have a razor blade scores scale. You will scale in activity.
