A2 Studying history is reading and discussing the stories historians have created about the past. Doing history is identifying questions about the past, researching evidence relevant to answering those questions, then creating your own stories from that evidence. #sschat

Q2: How is "Doing" history different than "Studying" history? #sschat

@CO2_earth Today’s reading (430.6) looks to me to set a new record high.

BREAKING: In a stunning moment, Rep. Jasmine Crockett asks the Mayors whether there are any immigrants roaming around their cities with 34 felony convictions (all answered no), "because that could be a danger to the community." She is a national treasure.

Quick reminder ahead of Donald Trump’s speech tonight:

He promised that he would “immediately bring prices down, starting on Day 1.”

It’s now Day 44.

Prices have gone up.

Inflation’s gotten worse.

And Trump’s done nothing to lower costs for working people.

#PPOD: Uranus Wide-Field

In the center of this wide-field image from @NASA_Webb 🛰️ is #Uranus, one of the ringed planets 🪐 of our solar system. That's an amazing capture, and it would be extraordinary on its own. But also captured are 14 of the planet’s 27 #moons 🌖: Oberon, Titania, Umbriel, Juliet, Perdita, Rosalind, Puck, Belinda, Desdemona, Cressida, Ariel, Miranda, Bianca, and Portia. Except for the few stars with diffraction spikes, everything else is a #galaxy!

Today, most of us take for granted abundant food, clean water, energy, and health. But this wasn’t always the case, as @CharlesCMann writes, “In Jefferson’s time, not even the president of the United States had what we have.” https://t.co/lNMGOD8Tvu

Hey, MAGAs this is what you voted for. We tried to rein in the GOP, save your Medicaid, collect more tax money from billionaires & get tax cuts for less wealthy Americans but the GOP in Congress voted NO. Let’s hope the Senate is not filled with GOP cowards!

There are no more Disease Detectives @CDCgov -- the Epidemic Intelligence Service is shut down, kaput. The EIS has for decades been the world's top outbreak investigation unit. So, States -- you're on your own now. Good luck solving mysterious ailments in Alabama.

Climate change threatens habitats that many endangered species need to thrive. Conservation efforts must take climate change into account when protecting habitat. https://t.co/LQxBWbAfwF #ClimateScience #environment #ecology #SciChat
