Privileged to engage with #NSELA60 leaders today to discuss the current historic moment & diverse sense-making from #SciEd frame. Here are my slides—PDFs, PPTs. I so appreciated the authentic & vulnerable conversation! #EquityFirst

@Mrs_Mongelli Agreed! Survival of the fittest? 🤔

[Kathleen Van Valen @MsVanValen]

Wow!! Check out this awesome publication that explains complex and often misunderstood mechanisms in a very accessible format 🤓

[Jacob A Tennessen @JacobPhD]

As promised: The Emoji Guide to Human Genetic Diversity. A scientifically whimsical online resource. Important stuff that everyone should know.

Thank you @Mrs_Mongelli and @RHSiCoach for your support throughout this past quarter as I tried out a LOT of new ideas! Our Ss carried out REAL science to build, test, revise, & evaluate their algae farms as a solution to climate change🌎

[Kristin Germinario Mongelli @Mrs_Mongelli]

Ss in @MsVanValen's class shared engineering successes & improvements, and used a peer feedback protocol to individually share noticings/wonderings on the sticky side of post its, followed by group discussions (a
@PBLWorks
strategy we experienced this summer!) #RandolphSchools

[Kathleen Van Valen @MsVanValen]

@MrAEmmons @RandolphHigh So cool! When can students start engineering solutions for the school with this technology?!😁

[Kathleen Van Valen @MsVanValen]

@miss_schilling_ @NGSS_tweeps We are using the same phenomenon to discuss cellular respiration! Students are loving it🏈

[Kathleen Van Valen @MsVanValen]

Can't wait to prepare bio students to work collaboratively on their algae farms and think like engineers!

[Kristin Germinario Mongelli @Mrs_Mongelli]

Excited to meet @MsVanValen’s honors biology classes tomorrow- they are about to dive into an epic engineering project! We are using scaffolds to support students’ understanding of the engineering design process (thanks @KnowlesTeachers) 🎉 #NGSS #engineering

[Kathleen Van Valen @MsVanValen]

Love when new inquiry activities work out! Students activated prior knowledge of photosynthesis & chemical indicators to interpret the photosynthetic ability of different flasks. So many "ah-ha" moments! 🌿

[Kathleen Van Valen @MsVanValen]

Plus students LOVE to decorate walls!☺️

[Kathleen Van Valen @MsVanValen]

This week in #APBio ... we explained how our cells communicate to maintain homeostasis using neurons! Good opportunity to have important & relevant conversations about substance abuse, tolerance, & addiction (on the cellular level!)

🙏🏼🐝

[Kathleen Van Valen @MsVanValen]

@Mrs_Mongelli @msbryanteaches @DukeFarmsFdn So great for our students to see successful sustainable practices out in the world!!

[@NGSS_tweeps @NGSS_tweeps]

Making non-fiction txt comprehensible to our SpEd & ELLs is part of our push towards equity in science. Here are 2 versions of the same Performance Task text. We used https://t.co/xmGXGqMvPL to quickly identify potentially problematic words. How do you incorporate reading #NGSS

[Kathleen Van Valen @MsVanValen]

Happy Halloween from (most of) @RandolphSchools biology!!! 💀🦊🐿

[Kathleen Van Valen @MsVanValen]

Check out these walls! 😍 so much space for student sense-making

[Victoria (Schilling) Curtis @miss_schilling_]

Student- led class modeling activity today!
“Can I add on to yours?”
“So I was thinking... and I heard this from other people too...”
“Would anyone like to agree or disagree?”
“Oh, you want to add on?”
ALL from students!!! #proudteacher @NGSS_tweeps #ngsschat #ngss

[Kathleen Van Valen @MsVanValen]

Making great progress designing authentic project-oriented units thanks to a lot of productive discussions with colleagues. Excited for September! @PBLWorks

[Meng-meng Fu @Meng2Fu]

Happy 4th of July - here are some cellular fireworks!

This oligodendrocyte is actively growing its microtubules. It's expressing fluorescent EB3, a protein that binds to the plus ends of microtubules and shows that most microtubules have directed growth away from the cell body.

[Kathleen Van Valen @MsVanValen]

@MrAEmmons Wow! So proud of our hard working students at RHS! Thanks for the support to make it possible! 😁🧬

[anthony emmons @MrAEmmons]

Blown away by our #AP Bio scores!
Outstanding work by our students and teachers!
@MsVanValen & Ms. Buchalski
Looking forward to 19-20 with 59 students!
Onward & Upward!
