Use common sense
• When in lab, pay attention to what you are doing
• Watch where you are going• Don’t push, shove, pinch, startle, or sneak
up on anyone• Don’t crowd around chemical or weighing
stations – everyone will get a turn

24Physical Science
Wash bottle
• Squeeze bottle• Often holds distilled water• Never touch the tip of a wash bottle to
anything.– After you stop squeezing, the bottle sucks in
air.– If there is a chemical on the tip of the bottle, it
will suck that in too.
![Page 25: Physical Science1 Laboratory Procedures. 2Physical Science Fume Hood Located between lab and prep room Prevents harmful fumes from entering lab May be.](https://reader030.fdocuments.in/reader030/viewer/2022032723/56649cff5503460f949cfe2e/html5/thumbnails/25.jpg)
25Physical Science
Measuring solids
• Use a balance• Place your weighing paper or other
container on the balance.• Push the ZERO button.• Make sure the balance reads zero before
you start putting the material on it.
![Page 26: Physical Science1 Laboratory Procedures. 2Physical Science Fume Hood Located between lab and prep room Prevents harmful fumes from entering lab May be.](https://reader030.fdocuments.in/reader030/viewer/2022032723/56649cff5503460f949cfe2e/html5/thumbnails/26.jpg)
26Physical Science
Measuring solids
• Add a little at a time so you don’t go over the needed amount.
• If you get too much, don’t put it back in the bottle.– Give it to someone else who needs it– Or put it in the waste beaker
![Page 27: Physical Science1 Laboratory Procedures. 2Physical Science Fume Hood Located between lab and prep room Prevents harmful fumes from entering lab May be.](https://reader030.fdocuments.in/reader030/viewer/2022032723/56649cff5503460f949cfe2e/html5/thumbnails/27.jpg)
27Physical Science
Measuring liquids
• Unless the directions say approximately, measure with a graduated cylinder.
• Use the smallest graduated cylinder that will get the job done – this will be the most accurate.
![Page 28: Physical Science1 Laboratory Procedures. 2Physical Science Fume Hood Located between lab and prep room Prevents harmful fumes from entering lab May be.](https://reader030.fdocuments.in/reader030/viewer/2022032723/56649cff5503460f949cfe2e/html5/thumbnails/28.jpg)
28Physical Science
Measuring liquids
• Read the graduated cylinder at eye level.– Don’t hold it up to your eyes.– Bring your eyes down to its level by squatting
or bending over.
![Page 29: Physical Science1 Laboratory Procedures. 2Physical Science Fume Hood Located between lab and prep room Prevents harmful fumes from entering lab May be.](https://reader030.fdocuments.in/reader030/viewer/2022032723/56649cff5503460f949cfe2e/html5/thumbnails/29.jpg)
29Physical Science
Measuring liquids
• Pour slowly so you don’t get too much– Be extra careful if you are using a funnel
• If you get too much, don’t pour it back in the bottle.– Give it to someone else who needs it– Or pour it down the drain with lots of water– Or put it in the waste beaker
![Page 30: Physical Science1 Laboratory Procedures. 2Physical Science Fume Hood Located between lab and prep room Prevents harmful fumes from entering lab May be.](https://reader030.fdocuments.in/reader030/viewer/2022032723/56649cff5503460f949cfe2e/html5/thumbnails/30.jpg)
30Physical Science
The meniscus
• Measure to the bottom of the meniscus

31Physical Science
Using droppers
• Like wash bottles, make sure the dropper tip doesn’t touch anything. – After you stop squeezing, the dropper sucks in
air.– If there is a chemical on the tip of the dropper,
it will suck that in too.

Cleaning labwareFor lightly soiled items:• Rinse three times with tap water.• Rinse once with distilled water.• Place in designated location.For heavily soiled items:• Apply a small amount of soap and scrub with your
fingers or a brush• Rinse with tap water until all the soap is gone (at
least three times)• Rinse once with distilled water.• Place in designated location.
