💡 Big idea: Real environmental datasets let you calculate dose and compare it to safety thresholds.
- 0-5 minWarm-up: what does a parts-per-million concentration mean in practice?
- 5-20 minOpen dataset; locate the pollutant concentration column and note units
- 20-40 minCompare values to published safe threshold; flag exceedances
- 40-60 minEstimate dose using concentration and assumed daily intake
- 60-72 minIdentify any time-trend suggesting bioaccumulation; note your reasoning
- 72-80 minExit ticket: report average concentration, threshold, and whether dose exceeds it
- • Today we work with the same type of data the EPA uses to set health warnings.
- • You'll open a real public dataset, identify the concentration column, and do a dose calculation.
- • Comparing your number to the safe threshold is how regulators decide when to act.
- • If values are rising over time, that's a bioaccumulation signal worth flagging.
- 1Open the provided air or water quality dataset.
- 2Identify the pollutant concentration column and its units.
- 3Compare measured values to a published safe threshold.
- 4Estimate dose using concentration and assumed intake.
- 5Flag any values suggesting bioaccumulation over time.
- • You compared dataset values to a safety threshold.
- • You estimated a dose and flagged any bioaccumulation concern.
- • Dose estimation requires knowing concentration, volume or mass intake, and body weight.
- • A safe threshold is a regulatory limit below which risk is considered acceptable.
- • Bioaccumulation occurs when a substance accumulates in tissue faster than it is eliminated.

Day 3 of this lesson. Open this exact section in myPLTW (reached through Schoology), then do the work below.
Do this: Open Problem 4 in your myPLTW course shell and navigate to the current activity, then analyze a public environmental dataset to estimate exposure dose and compare to a safe threshold.
Add your data analysis results to the Problem 4 evidence portfolio.
The exposure pathway diagram is done; this is a mid-Problem 4 milestone, so check your activity guide and confirm your data analysis is on pace.

Check things off as you work, then submit. This tells Mr. Mendoza how you're doing so he can help the class. It does not replace turning in your producible on Schoology.

This is how Mr. Mendoza sees the class keeping pace with PLTW. Be honest, it only helps if it is accurate.
