Put on the correct safety lab gear

[[PUT ON YOUR SAFETY GEAR - PUPELLO]

114207_2 — 2025-09-22 16:50:56 UTC

you should prepare your protective gear, you should make sure that you fully understand what your about to do, and prepare your workspace.

what should you do before starting a lab? [PUT ON SAFETY EQUIP - PUPELLO]

222314_24 — 2025-09-22 16:53:25 UTC

get what any type of objects you need for whatever your working on like goggles and make sure your in a clean inviroment and making sure your safe in any way

you should (c) inform the teacher

210833_13 — 2025-09-22 16:53:58 UTC

you should put on your glasses, tie your hair, put on all the tools you need to be protected, and clean all your work space to prevent accidents.

[More importantly, what else??? - PUPELLO]

222986_4 — 2025-09-22 16:55:22 UTC

Before starting a lab, you must understand the experimental procedure, including its hazards and the location of safety equipment like fire extinguishers and emergency showers.

make sure you have the safety stuff on

Check safety equipment and make sure everything is set up correctly

[Include true/false in your answer! - PUPELLO]

222986_4 — 2025-09-25 16:51:27 UTC

No, you cannot take off your safety goggles before other students are done with their lab; safety goggles must be worn at all times when in the laboratory, even if you have finished your experiment, unless you have received permission from the instructor to leave the room.

No because they still working in a lab, That chemical can splash in your eyes and skin. The only way you can remove your glasses is if you move far away from the lab so no chemicals can splash anywhere on your body.

A single measurement, by definition, has nothing to be compared against.

A single measurement isn’t enough to determine precision because precision refers to how consistently measurements are repeated

1884213 — 2025-10-01 16:53:32 UTC

precision is the consistency of set measurements

1849603 — 2025-10-01 16:54:15 UTC

210833_13 — 2025-10-01 16:54:41 UTC

a single measurement ins't enough because the precision is consistency, for consistency you need multiples trys, not just one

A single result provides no information about precision, as precision is determined by how consistently the same result is produced in repeated trials.

false?/True

[Explain WHY - PUPELLO]

222986_4 — 2025-10-06 16:39:52 UTC

8.25 inches is a more precise measurement

A single measurement is not enough to determine precision because it does not show how consistent or reproducible the measurement process is. Multiple measurements are needed to observe the variability and assess the precision of the measurements.

221293_15 — 2025-10-06 16:44:19 UTC

[Incorrect - PUPELLO]

114207_2 — 2025-10-06 16:45:44 UTC

8 inches is more accurate because its an exact measurement unlike 8.25

8.25 inches is more accurate because it is measured with greater precision.

221293_15 — 2025-10-06 16:45:53 UTC

[What do you mean? Be more specific - PUPELLO]

1780274 — 2025-10-06 16:46:43 UTC

8.25 because it gives the exact measurement

[Incorrect - PUPELLO]

1791712 — 2025-10-06 16:48:21 UTC

Because the measurement can be off by the slightest

[Incorrect - PUPELLO]

210833_13 — 2025-10-06 16:48:29 UTC

8 because has no middle decimals of fractions

[Incorrect - PUPELLO]

186502_6 — 2025-10-06 16:49:59 UTC

8 inches is more accurate because its straight forward

[Explain WHY - PUPELLO]

1791712 — 2025-10-06 16:50:27 UTC

8.25

8.25 inches because includes more decimal detail, indicating a finer level of precision.

1884213 — 2025-10-06 16:50:35 UTC

[Incorrect - PUPELLO]

1986291 — 2025-10-06 16:53:11 UTC

8 inches is more accurate becasue its closer to the correct value.

[Explain what you mean - PUPELLO]

1849603 — 2025-10-06 17:07:13 UTC

8.25 because it has more precise detail

Do Now 10/6

227698_2 — 2025-10-07 04:05:32 UTC

The measurement of 8.25 inches is more accurate because it includes a decimal, showing it's a more exact and precise measurement.

when reporting results of a measurement

To reflect the precision of the measuring instrument. For example, a ruler marked in millimeters allows for more significant figures than one marked only in centimeters. To ensure the result does not imply greater precision than the least precise input measurement
