What is an acceptable safety goal for a science lab? • Is 90% acceptable? • Number of classes per day = 6 • Number of students per class = 28 • Number of years in a career = 30 • So the total number of students taught in a career would be 6x28x30 = 5040 • If just 1 student got seriously hurt, my safety percentage would be 5039/5040 = 99.98%
99.98% is pretty good unless you are the 1 student that gets seriously hurt! • So my goal is 100%
# 1: Beaker #2 : Graduated cylinder • Uses: • Measure, store and heat liquids • Large amounts • Uses: • Measure and store liquids • Small amounts • More accurate Safety Precautions: Glass is breakable Hot glass looks like cold glass
#3: Test tube #4: Agar Plate • Uses: • For growing bacteria; the red jelly is the agar. It is full of “food” for bacteria • Uses: • To store small amounts of liquid (usually) Safety Precautions: Test tube is glass = breakable Agar is NOT food for people (no eating)
#5: Triple beam #6: Ruler Balance • Uses: • Get the mass of objects and materials • Units are grams • Uses: • Get the length and/or width of geometric shapes • meters or cm Safety Precautions: TBB are heavy Rulers are NOT small swords or bats– don’t use them that way!
#7: Thermometer • Uses: • Get the temperature of liquids being heated • Units are oC and/or oF Safety Precautions: usually glass so handle with care
