Class/Safety Rules

POWHATAN COUNTY PUBLIC SCHOOLS

SCIENCE SAFETY RULES AND PROCEDURES AGREEMENT

In order to ensure that science experiments are safe and positive learning experiences, students and their parents should read, discuss, and sign this science safety rules and procedures agreement. No student will be permitted to participate in laboratory work until this agreement is signed by parent and student and returned to the teacher.

Act in a responsible manner at all times. Misconduct that endangers any student will not be tolerated.

Never work without adult supervision. Do not handle any materials until instructed by the

teacher to do so.

Perform the experiments as directed. Do not do anything which is not part of an approved

experimental procedure. Follow all instructions given by the teacher. Read the written procedures.

If you don’t understand a procedure or piece of equipment, ask the teacher.

Use of tobacco products, eating, or drinking in the lab or experimental work area are forbidden.

Wear appropriate protective equipment A lab coat or apron and ANSI approved eye protection should be

worn when necessary. Keep hands away from face, eyes, and mouth while using chemicals or preserved

specimens.

Learn the locations and operation of emergency equipment including eyewash fountains, safety

showers, fire extinguishers, fire blankets, etc. Report all accidents, injuries, closecalls, or unsafe

conditions to your teacher.

Shoes must be worn at all times; never go barefoot in the lab. Special care should be taken with floppy

clothing. Tie back long hair to keep it away from flames and chemicals.

Never taste a chemical. Never pipette by mouth - always use a pipette bulb.

Check odors only if instructed to do so by gently wafting some of the vapor toward your nose with your

hand.

Carry sharp objects with tip or sharp edge pointing downwards.

Use caution when heating materials in the lab. Keep hands and face away from the mouth of a test

tube or beaker being heated. Turn off burner or hot plate when you are finished never leave an

active heat source unattended.

Do not enter science prep rooms or storage areas unless under teacher supervision.

Never take chemicals, supplies, or equipment out of the laboratory without the knowledge

and consent of the science teacher.

Clean your lab area; put away all equipment and reagents; wash your hands at the end of each work

session. Report any damaged glassware or equipment to your teacher.

Additional safety instructions may be added to the back of this form by your science teacher.

I , _______________________________ have read, understand, and agree to follow these science

safety rules and procedures. I agree to abide by any additional instructions, written or verbal, provided by my science teacher or adult supervisor.

Powhatan County Public Schools Physical Science Student Learning Goals

Virginia Standards of Learning
The student will:

PS.1 plan and conduct investigations in which

· length, mass, volume, density, temperature, weight, and force are accurately measured and reported using the International System of Units (SI - metric);

· triple beam and electronic balances, thermometers, metric rulers, graduated cylinders, and spring scales are used to gather data;

· data from experiments are recorded and interpreted from bar, line, and circle graphs;

· research skills are utilized using a variety of resources;

· independent and dependent variables, constants, controls, and repeated trials are identified;

· valid conclusions are made after analyzing data;

· research methods are used to investigate practical problems and questions; and

· experimental results are presented in appropriate written form.

The student will investigate and understand:

PS.2 the basic nature of mater. Key concepts include

· the particle theory of matter;

· elements, compounds, mixtures, acids, bases, salts, organic, inorganic, solids, liquids, and gases;

· characteristics of types of matter based on physical and chemical properties;

· physical properties (shape, density, solubility, odor, melting point, boiling point, color); and

· chemical properties (acidity, basicity, combustibility, reactivity).

PS.3 various models of atomic structure including Bohr and Cloud (quantum)

models.

PS.4 how to use the periodic table of elements to obtain information. Key

concepts include

· symbols, atomic numbers, atomic mass, chemical families, periods, valence numbers, metals, metalloids, and nonmetals; and

· binary compounds (chemical activity, physical properties, formulas, and nature of bonding).

PS.5 changes in matter and the relationship of these changes to the Law of

Conservation of Matter and Energy. Key concepts include

· physical changes (effect of temperature on state, particle size on solubility, and temperature on solubility);

· nuclear reactions (products of fusion and fission and their effects on human beings and the environment); and

· chemical changes (types of reactions, reactants and products, and balanced equations).

PS.6 states and forms of energy and how energy is transferred and transformed.

Key concepts include

· potential and kinetic energy;

· mechanical, chemical, and electrical energy; and

· heat, light, and sound.

PS.7 temperature scales, heat, and heat transfer. Key concepts include

· absolute zero, phase change, freezing point, melting point, boiling point, conduction, convection, radiation, vaporization, and condensation; and

· applications of heat transfer (heat engines, thermostats, and refrigeration).

PS.8 characteristics of sound and technological applications of sound waves.

Key concepts include

· wavelength, frequency, amplitude, interference; and

· technological applications of sound.

PS.9 the nature and technological applications of light. Key concepts include

· reflection, refraction, particle theory, wave theory; and

· electromagnetic spectrum.

PS.10 scientific principles and technological applications of work, force, and motion. Key concepts include

· work, force, mechanical advantage, efficiency, power, horsepower, gravitational force, speed/velocity, mass/weight, Newton’s three laws of motion, acceleration; and

· applications (simple machines, compound machines, powered vehicles, rockets, restraining devices, projectiles).

PS.11 basic principles of electricity and magnetism. Key concepts include

· static, current, circuits; and

· magnetic fields and electromagnets.
