@MCPS recently gave its 45-day notice to the teachers union @mceanea so they may start talks to re-open schools.

📢 Here's what teachers, parents & students should be demanding before they step foot in a school (A thread/1) Checks on the HVAC system and #ventilation

1. What kind of system does your school have?
2. Is the ventilation rate meeting minimum requirements in code?
3. What can be upgraded in-time for school re-opening?

An article shared at @NIST: Does color really matter in data visualization?

Many programs apply default color settings to your figures, but those colors may not be the best choice. Color vision deficiency (CVD) affects a significant percent of the population /1 with red-green color vision defects being the most common. nature.com/articles/nmeth… Contrast, saturation, and hue are important options to consider when choosing colors for your figures. /2

#EnviroHealthMatters Interesting slide from Jay Butler, @CDCgov . Could work this into a framework for what you decide to do when venturing out

Watch now: ow.ly/t5Wp50B9zGr @theNASEM AVOID AVOID AVOID these Cs #EnviroHealthMatters

Key takeaways from Tod Companion and Justine Parker

- how do we take complex risk ideas & connect them to people, while addressing each person's risk benefit and decision
- trust, transparency and respect should be core business values for recovery

#CLEAN2020 @Clean2020Summit Key takeaways from @ChemDelphine and Darla Goeres

- important to follow directions on disinfectants & understand material compatibility
- huge amount of research happening now (very exciting) with regards to decontamination
- don't forget about toxicity of secondary products!

Draft plan for re-opening MCPS schools: montgomeryschoolsmd.org/reopening/MCPS…. Highlights (thread):

* School will start Monday, Aug 31 with reduced class size
* MCPS will be virtual-only to start the year given current conditions * Students will return on a rotational schedule by grade level, last name/address (see Phase 1-Phase 3 below)
* Once your grade is allowed to be in-school, they will follow a weekly rotation of 2 days in-person, 2 days at-home (high school schedule looks 😨)

When schools re-open, how about high schools starting an hour later? I've heard so many parents saying the extra sleep has been so helpful for their teens. /1 cdc.gov/features/schoo…

A thread I acknowledge the challenges - (1) work schedules of parents and drop-off times. Maybe telework or shifted hours would allow parents to work and teens to sleep. /2

United States was formed through pillaging ($1 million worth of tea into the Boston Harbor) which sparked the American Revolutionary War. In 1776, the Declaration of Independence was signed which read "that all men are created equal..." /1 ...that they are endowed by their Creator with certain unalienable Rights, that among these are Life, Liberty and the pursuit of Happiness."

But those rights, that life, and that liberty was for the white straight man and the rest of us have been fighting for it ever since. /2
