VIDEO CLIP http://www.youtube.com/watch?v=47rQkTPWW2I HOW DOES THIS RELATE TO WHAT WE TALKED ABOUT YESTERDAY?
A way of learning more about the natural world that provides possible explanations to questions and involves using a collection of skills. Science helps us answer questions and solve problems. Science is the process of trying to understand the world.
Observation Background Information: One of the most important skills in science is that of OBSERVATION. Most of the time we think of observation as something we do with our eyes; when we see something, we observe it. However, all five of our senses can be used to make observations: sight, hearing, taste, touch, and smell. We can make two kinds of observation: those that are FACTS, and those that are OPINIONS. Facts are those things that are true for everybody. Opinions are beliefs based on personal preference.
Observation Activity Procedure: 1. Close your eyes. Keep them closed! 2. Use your sense of TOUCH to observe the object I put in you hand. 3. Write at least three sentences describing what you observed.
4. Use your sense of HEARING as you LISTEN the object. 5. Write at least three sentences describing what you observed.
6. Use your sense of SIGHT to observe the object. 7. Write at least three sentences describing what you observed.
8. Use your sense of SMELL to observe the object. 9. Write at least three sentences describing what you observed.
10. Place the object in your mouth. Use your sense of TASTE to observe it. 11. Write at least three sentences describing what you observed.
Describe the purpose and care of commonly used pieces of lab safety equipment such as: triple beam balance, graduated cylinder, thermometer, spring scale, and ruler.
GUIDING QUESTIONS Explain the purpose of at least five lab safety rules.
GUIDING QUESTIONS What measuring tools would you use to determine the following physical properties of matter: length, temperature, mass, volume, weight and density? What tools are used to determine the boiling point of a substance?
GUIDING QUESTIONS Demonstrate the ability to find the volume of a regular and irregular solid.
OBJECTIVES - 1. The locations and usage guidelines of safety equipment in the classroom 2. There are lab safety rules that must be followed in the lab 3. Understand purpose of MSDS - Material Safety Data Sheets.
Bell Work GET OUT YOUR SIGNED SAFETY CONTRACT AND CLASS RULES. Grab your passport. What would you do if one of your classmates was injured in class? Work with your groups and develop a set of 3 guidelines for working in a science lab. Write your 3 guidelines in your passport.

Sixth Grade Science Laboratory Safety Rules I m Labbie, your laboratory retriever. When you see me, it s a friendly reminder to follow all lab rules and safety procedures.
Sixth Grade Science Laboratory Safety Rules Scientific laboratory is a place of adventure and discovery. Some of the most important events in scientific history have happened in laboratories. The antibiotic powers of penicillin were discovered in a laboratory. Plastics used today for clothing and other products were first made in a laboratory. The list is endless.
Sixth Grade Science Laboratory Safety Rules One of the first things any scientist learns is that working in the laboratory can be an exciting experience. However, the laboratory can also be quite dangerous if proper safety rules are not followed at all times. In order to prepare yourself for a safe year in the laboratory, read the following safety rules. Then read them a second time. If you do not understand each rule, ask your teacher to explain any rule that is unclear.
SAFETY CONTRACT ENGLISH http://www.flinnsci.com/Documents/miscPDFs/safet y_contract_MS.pdf SPANISH http://www.flinnsci.com/Documents/miscPDFs/safet y_contract_MS_SP.pdf
Safety Contract Dress Code Tie back long hair. Remove dangling jewelry. Do not wear loose, billowy clothing. Wear closed-toed shoes; sandals don t protect your feet. Laboratory Behavior Read all directions for an experiment several times. Listen carefully during the pre- lab. Ask questions if you do not understand any part of the experiment. Follow the directions exactly as they are written. Make sure the work area has been cleared of purses, books, jackets, etc. Before starting the lab, be aware of all safety precautions and know the location of all safety equipment. Do not speak loudly or engage in horseplay in the laboratory. Never eat or drink in the laboratory.
Safety Contract Safety During the Laboratory Lesson Never perform activities that are not authorized by your teacher. Do not handle any equipment unless you have permission. Wear safety goggles, lab aprons, and protective gloves when required. Take extreme care not to spill or break any material in the laboratory. Clean-up procedure Follow your teacher s instructions for proper disposal of chemicals; do not pour anything down the drain unless instructed to do so. Do not work alone in the lab. Report all accidents to your teacher immediately. End-of-Experiment Rules Clean up your work area and return all equipment to its proper place. Wash your hands after every experiment.
Safety Contract You will now receive your personal safety contract. This MUST be signed and returned by tomorrow. You MUST read over the rules and sign with your parent. IF YOU DON NOT HAVE YOUR SIGNED SAFETY CONTRACT, YOU WILL NOT BE ABLE TO PARTICIPATE IN LABS. NO EXCUSES. If you lose your contract you may print another one from the notes on the website.
Safety Spots in Our Class Eyewash fountain demonstration. Show location of fire blanket, fire extinguisher. Aprons and gloves. Goggle cleaning station.
Map of Classroom Draw a map of the classroom. Label all of the safety spots. (Fire blanket, goggle station, fire extinguisher, eyewash station) Label all the exits.
RECYCLING AND CONSERVATION What substances can be washed down the drain? Never return unused chemical to an original jar (called a stock jar or the reagent jar ). Review types of items that can be recycled: glass, paper, aluminum, certain plastics, etc. (NOT WOOD)
MSDS Material Safety Data Sheets.

Dear Mad Scientist Safety Letter: You are the Mad Scientist. Yesterday you received this note in the mail. Now you need to reply providing the science student with the information they requested. Dear Mad Scientist, School starts in a few days. I am excited and nervous. I love science and can t wait to get into science lab! Last year I got in trouble a lot for playing with the materials and making my own directions. What should I do so I don t get in trouble this year? Sincerely, Curious Kate Dear Curious Kate, Sincerely, Mad Scientist
OBJECTIVES Various pieces of equipment are used in the lab There is a proper way to use and care for all pieces of lab equipment
Your Journals Yes, journals are a type of lab equipment. You are going to be keeping a science all year. This journal will be a place for NOTES and VOCABULARY, as well as some LABS and ACTIVITIES. You will have quizzes over the information in your journal. You must bring your journal to class EVERYDAY.
Triple Beam Balance Expert Information: Balances are used to measure mass. The units of mass are grams (g) and kilograms (kg). The instrument you will use most often to measure mass is the triple beam balance. The triple beam balance gets its name from three long, horizontal metal bars called beams connected to a pointer on the right-hand side. The pointer should always be at zero point before obtaining the mass of any object. On each beam is a rider that slides across the beam.
Before using a triple beam balance, you should remember the following: Slide all riders back to 0 on the beams before massing any object. Use the adjustment knob to zero out the instrument if necessary. Place the object to be massed on the pan. Chemicals should be placed on waxed or filter paper before massing. Gently slide the riders along the beams while determining mass. The pointer will swing above and below the zero point while you are adjusting the riders. Make sure each rider is in a notch before reading. The mass of the object will be the sum of the masses on all beams. Always return the riders to zero BEFORE removing the object from the pan.

Graduated Cylinder Expert Information: A graduated cylinder is used to measure liquid volume. The unit is the milliliter, abbreviated mL. To use a graduated cylinder, you must remember the following: Place the graduated cylinder on a flat surface and view the height of the liquid in the cylinder with your eyes directly level with the liquid. The liquid will tend to curve downward. This curve is called the meniscus. The graduated cylinder will usually have heavy markings at 10, 20, 30 . . . milliliters. There are usually smaller markings in between the larger units called graduations. Read the graduated cylinder to the nearest tenth of a milliliter (31.5 mL or 30.0 mL).
Meniscus Notice how the liquid curves up the side of the graduated cylinder. To get the most accurate reading, read the measurement at the bottom of the curve, or meniscus.
