Lab safety, myPLTW, and how to submit

Your goal: Pass a lab-safety check and sign the safety contract, tour the myPLTW web portal, and learn exactly how to submit each kind of work.

One product: Lab-safety check: signed safety contract, completed safety scavenger hunt, and course-access check (login screenshot if available, or a note that access is unavailable).

If the assignment or access is unavailable, save the dated written preparation locally and ask the teacher for help opening the assignment. Complete the actual hunt, signatures and safety checks through the teacher's directions if you have not done them. Use a genuine login screenshot if actual course access is available; otherwise provide the access-unavailable note. Do not infer a completed activity from a login.

Start the work

Use a cue, recall, check, and revise.

Icebreaker: Would You Rather, lab edition (goggles for a day or gloves for a week?).
Learn lab safety: PPE, reading an SDS, and the SOP for handling, storing, and cleaning up.
Lab-safety scavenger hunt: find the eyewash, the fire blanket, the SDS binder, and the PPE in our room.
Read and sign the lab-safety contract (a copy goes home for a parent signature).
myPLTW student access is not available yet. Follow the teacher's course tour and write access unavailable for your access check. Then practice finding the matching Schoology assignment for a notebook sample, exit ticket, and lab write-up.

Show the 80-minute plan

0 to 6 minutes. Use H1 and E2 for the icebreaker and both opening questions.
6 to 25 minutes. Read E1/E2/N1 and M1; complete all five section matches.
25 to 40 minutes. Answer S1 and repair the overclaim; say which room and contract actions you actually did and what you need next.
40 to 65 minutes. Use R1 to match all three artifacts and practice checking the proposed route. Record tour and access check.
65 to 80 minutes. Answer Q1, complete the solo review and P1 work-check record; save or submit through the linked assignment.

H1: written preparation and actual checks

Today has written work and actual classroom checks. This page supplies the written practice. It does not sign the contract, locate equipment or pass the teacher’s safety check for you.

For the icebreaker, discuss goggles for a day or gloves for a week. This is a question, not an instruction to wear either item for that time.

Answer the opening questions: do you know the actual eyewash location, and what does one PPE item help protect? Write location not checked if you do not know.

Use the reference cards, scenario and model before answering. Leave materials untouched during this paper practice. The teacher directs any real equipment use or room tour.

E1: rules in the local safety contract

The linked Student Safety Contract says to follow written and spoken directions, ask when unclear, and obtain teacher permission before touching equipment or materials. Only approved activities are allowed. [CONTRACT]

It requires reporting accidents, injuries and unsafe conditions to the teacher right away. Follow the teacher’s directions for waste and cleanup. This page gives no cleanup method.

It requires learning safety-equipment locations and use. A copied example is not a room observation. Do not operate equipment or enter storage areas just to complete this written work.

It requires student and parent or guardian signatures on file before participation in science activities. Reading these cards does not complete either signature or prove permission.

Read the actual full contract with the teacher. Handle its signature and personal questions through the teacher’s private local process. This practice record asks what you have done and what you need next, not for signatures or health details.

E2: protection depends on the task

PPE means personal protective equipment. Suitable eye protection can help shield eyes; gloves can help protect hands; an apron or coat can help protect skin and clothing.

No one item protects against every hazard. CDC’s laboratory risk guidance considers the task, hazards, setting, staff training and controls together. [CDC]

The teacher must select suitable protection and teach its use for the actual task. An SDS informs those choices but does not replace the local SOP or permission.

For the prerequisite, observe or try assigned PPE only when the teacher directs you. In written practice, name an item and its general purpose; ask the teacher to check its fit and suitability for the task.

N1: a source-navigation reference

This is a section guide, not a chemical’s SDS. It contains no chemical name, hazard rating, first-aid treatment or handling procedure.

The Canadian Centre for Occupational Health and Safety lists these SDS headings: 1 Identification; 2 Hazard identification; 4 First-aid measures; 7 Handling and storage; 8 Exposure controls/Personal protection. [CCOHS]

A real SDS must match the actual product. Its general information may need further workplace instructions. The Canadian guide explains document structure; it is not a statement of Ohio school law.

Navigation practice: for questions about product identity, hazards, first aid, storage and PPE, write the section number and heading. Then state why this guide cannot answer a chemical-specific question.

Actual remediation requires the teacher-selected matching SDS and its first-aid section. Actual extension requires one hazard from that SDS. If it is missing, name the input you need and ask the teacher; do not invent its contents.

S1: a fictional missing-information case

In this invented case, a learner has read the contract. No signatures are on file yet. The teacher has not supplied the task, its SOP, matching SDS or permission to handle materials.

The learner has not checked the room’s safety-equipment locations. A peer says that gloves used last time are enough. No actual chemical, equipment location or experiment is described.

Choose the next action for this case. Cite E1 and E2, name two missing inputs and explain why each matters. Write what you actually did and what you need next.

Challenge statement: I read the rules, so my hunt, signatures and official PLTW activity are complete. Replace it with one accurate sentence and explain two unsupported claims.

R1: three fictional artifacts and route cards

These are paper matching inputs, not live assignments. Route A accepts a notebook sample showing notes, cue questions and a summary. Route B accepts an exit ticket answering one closing question.

Route C accepts a lab write-up organized as question, supplied evidence, explanation and limit. These descriptions explain submission matching; they do not assign or describe an experiment.

Artifact X is an invented page with cue questions, a notes column and a summary about class routines. Artifact Y is one paragraph answering a closing question about checking evidence.

Artifact Z is a fictional document with question, evidence, explanation and limit headings. It contains no measured data. Match X, Y and Z to A, B or C and cite a visible feature.

For each match, describe what you would check before upload: enrolled course, assignment description and intended attachment. Actual assignment names and file requirements must be checked in Schoology.

The website provides the daily target. Schoology carries the matching class assignment. myPLTW contains official course work. Opening a course proves access only, not activity completion.

Student myPLTW access is unavailable today. Record access unavailable for that branch and follow the teacher’s tour. Do not attempt a sign-in through this written exercise.

If the teacher later confirms access, record the real course-access result and required login screenshot locally. Never share passwords or account details here. A screenshot of access is not an activity submission.

Q1: check and recover

Self-check: what evidence belongs in the actual daily product, and where does it go? Use E1 and P1. Separate the physical contract from the Schoology record.

Answer check: hand the genuinely signed contract to Mr. Mendoza. Send the completed hunt and access check to the confirmed matching assignment. Use a real login screenshot if available, or an access-unavailable note.

For a solo review, check two things: did each answer use a supplied rule or input, and did any sentence claim an action you did not perform? Revise one error or explain why your record is accurate.

If stuck, complete one N1 heading match and explain it. Then finish all five heading matches, all three artifact matches and the case. A short recovery does not replace the complete written work.

If absent, finish this paper work and ask how to complete the supervised hunt, PPE lesson, safety check and contract process. Do not mark those actions complete from home.

P1: keep each actual requirement visible

Keep separate rows for written practice, full contract reading, student and guardian signature return, supervised safety check and teacher permission. Give each location its own row: eyewash, fire blanket, SDS binder and PPE.

Also record the teacher-selected SDS and SOP lesson, task-specific PPE instruction, teacher portal tour, actual course access and matching Schoology submission. For each item, give evidence of what you actually did or name the next action you need.

Today’s physical contract goes to Mr. Mendoza. The hunt and course-access check belong in the matching Schoology assignment. The dated folder is Class Records.

Use the linked BI assignment for today’s safety hunt and course-access check. Read its posted directions, format and deadline. If access fails, save the work locally and ask the teacher for help.

Follow the teacher’s current direction about course access and record only the actual access state.

Confirm remaining due dates with the teacher. January 26 is the pretest and goal-setting lesson.

No homework is due before this class. Finish any earlier website, notebook or orientation work that you have not done.

January 21 was the previous BI notes lesson. January 27 is a separate course-launch lesson. Today assigns no official myPLTW activity.

An official activity, safety check, signature or submission is complete only when its real requirements are met. Keep missing inputs visible and continue the supplied written practice.

M1: a different record and correction

Original model: an invented learner has finished a practice worksheet for another class. The intended worksheet file is saved, but the real Schoology assignment cannot be opened.

Before statement: My worksheet is submitted because I saved it. After statement: My worksheet file is saved; I need help opening the assignment before I can upload it and check that Schoology shows Submitted.

My reason is that a local file and a received submission are different evidence. I can describe the saved worksheet, but cannot claim an actual upload.

My record says: the worksheet is saved locally; next I need help opening the assignment so I can upload my work. No account or private record is supplied.

This model corrects a claim about what was actually done. Apply that distinction to S1 yourself; a worksheet example does not answer the missing safety-input case.

Try the decision

A different case from S1: signatures are on file, but the teacher has not named today’s task, SOP or matching SDS. A classmate says to start with the gloves on the bench. Which action follows the supplied rules?

Leave materials untouched and ask the teacher for the task, SOP and SDS first.
Put on the bench gloves and start because the signatures are on file.
Record the task as complete because the contract is already signed.

Explain your choice using the reading. Discuss it or say it to yourself. This practice does not add another submission.

Your response record

Use these labels on paper or in your document. The space below also works when this page is printed.

Opening safety questions

Discuss the icebreaker. Record whether the eyewash location is known or not checked; name one PPE item and its general protective purpose.

Do not guess a room location or try equipment. H1 and E2 supply the written route.

Find the information type

Match product identity, hazards, first aid, storage and PPE to N1 section numbers and headings. Explain one fact this guide cannot supply.

Use the five supplied headings. Ask the teacher for the actual matching SDS before attempting chemical-specific remediation or extension.

Choose a supported next step

Answer S1 with a next action, E1 and E2 support, two missing inputs with reasons, and what you actually checked.

Distinguish reading from permission, signatures and supervised checks.

Repair the overclaim

Replace S1’s challenge statement with an accurate sentence. Explain two unsupported completion claims.

M1 models a different correction. Keep only actions supported by the stated record.

Match three kinds of work

Match X, Y and Z to routes A, B or C. Give a visible feature for each and name the checks needed before an actual upload.

All descriptions are in R1. These fictional routes do not create live assignments.

Evidence and destinations

Answer Q1: list the three actual product parts, their destinations and the access-unavailable alternative. Then complete both solo review checks.

Do not create a signature or screenshot. Cite E1, R1 or P1 and revise an error or justify accuracy.

Separate written work from actual actions

For every P1 row, write what you actually did or what you need next. Add actual evidence or a next action. Keep the real contract, hunt, access check and submission distinct.

No health details, names, passwords, signatures or invented observations belong in this written record.

Check your product

The written case uses the supplied rules and identifies missing inputs without guessing.
All five navigation matches and three artifact matches include their reasons or headings.
The record distinguishes written work from actual room checks, signatures, safety approval, access and submission.

This original written preparation cannot authorize handling materials, pass the actual safety check, provide a chemical-specific procedure or complete signatures, official activities or submissions.

Turn in your work

Wk2 Pre-lab: Lab safety, myPLTW, and how to submit

Hand Mr. Mendoza the genuinely signed contract. Use the linked BI assignment for the completed safety scavenger hunt and course-access check. Ask how this written preparation should accompany that work before uploading. After uploading, check that Schoology shows Submitted.

Open this assignment in Schoology

Connection to PLTW

Original written safety preparation with genuine classroom checks retained.

These references locate related course material. Complete only the official work and stopping point your teacher assigns. This local preparation does not establish completion of an online activity.

Optional practice and examples

Use these resources to practice related skills. Follow the required work and evidence limits above. A simulation does not authorize a live experiment or add another submission.

Open the worked example. Compare the method with your own work; retain your assigned records and product.

The Glove That Failed

Slides and optional notes

Keep five section matches, three artifact matches, the case and correction, self-check and full record of what you did or need next. The written record does not replace the signed contract, room hunt or access evidence. Guided notes are optional and do not add a second submission.

Keep going

If you were absent or lost your place, read the word guide and reading first. Try the example, then complete the first unfinished response.

No partner is required. Read your response aloud to yourself and check it against the product checklist.

Take home: Use the matching rule, record only what you checked, and ask the teacher for missing safety or access requirements.

Use what you actually completed and what you still need when you set a learning goal on January 26. Which completed check or unresolved need should shape your learning goal?
