Edit just draw/label what each look like. Usually in chapter 1 or 2 of textbook or lab book. Teach just wants to know that you read looked at because they don’t want you lost/confused first day or any day of lab. No time to help you find a 100ml flask trust me with a schedule experiment.Trust me if they say get x,y,z from station drawer. you better know what they are and get them out. Time is of the essence you don’t finish experiment …they know and it prevents you from finishing conclusin of lab etc.
Both flasks and beakers hold liquids etc and have numbers on side in ml/L.
1.Flask – glassware in lab that has a narrower top than beaker. Put strong chemicals in you want to control contact with. ie strong acids/bases etc. Do not want splashig around. Often mix chemical or liquids/powders in titration etc.
2. beaker- most liquids can be placed in these. Weak acids/bases etc.
3. graduated cylinder-Measuring device for liquids. often 100ml in hs labs. but do have larger ones.
4.eye dropper – use when you want to measure out small controlled specific amounts of liquids.
5. cork/rubber stopper – put on top of test tube flask for safe mixing, or prevent spills.
6. test tube -holds small quantities of samples in lab, nonumbers on sides but easy to use and clean.
7. test tube rack -holds your test tubes to prevent breakage, spills, leaks, able to hold various tests of experiment at once, able to use to label /organize experiment
8. test tube clamp-often used to hold test tube especially when heating over bunsen burner
9. test tube brush -use in cleaning of test tubes after experiment
10. hand lens -aid eye to study/observes small granuales of powders/crystals
11. petri dish – augar medium filled plastic/glass dishes to grow organisms/ cultures on. ex mold/bacteria
12. safety goggles -must wear to protect your eyes in lab class
13. forceps – scientific tweezers used to pick up lab specimens/samples
14. triple beam balace – scientific scale used to measure mass in grams during lab.
15.funnel -Use in lab when you want to filter sediments/solids/particles from liquid portion in lab.
Been awhile let me know my grade on this homework assignment after teacher grades. LOL
