I made an online practical and simulation database for my department this year. I only went for student-friendly ones. Happy to share it here for the new academic year! bit.ly/OnlinePracticals #STEMeducation #Edutwitter #ChatBiology #ChatChemistry #ChatPhysics
I cannot in good conscience stay on Twitter with the news about the amplification of neonazis and the CSAM used to train its AI to actively produce sexual images of both children and adults. Moving to BlueSky. Please drop your handles before I go, and tell me who to follow.
Estoy en el aeropuerto y no me dejaron sentarme a darle pecho a mi bebé en sillas están vacías, xq están en el área de @united y mi check in es al lado en BA. Prefieren sillas vacías que proteger a las infancias. ¡Qué vergüenza de United y del personal de aeropuerto! #lactancia

One of my favourite #ScienceClub activities using rhubarb to investigate how surface area affects the rate of reaction.

Scientists have uncovered how a protein named IRF1 supports the reprogramming of #macrophages to tune the innate immune response, which could inform efforts to predict or alter the functions of these immune cells. @scisignal scim.ag/4jiBRBH
Really proud of my Y12 for their beautiful results from our practical yesterday. They learnt how to prepare slides of garlic roots. We found so many phases in anaphase! #Microscopy #Biology
How to motivate Y12 to really make an effort retrieving everything they know about mitosis? With mitosis cookies, of course! Can't eat them unless I'm satisfied that all the info is there! @chatbiology @Bakerlogy

Last Sunday, @AsimovPress published an article explaining why it's so hard to diagnose tuberculosis.
Here are 10 interesting things we learned about TB while editing it:
1. TB (not malaria) is the deadliest infectious disease. It kills >1.2M people each year.
Today my Y11 got the most beautiful curve for rate of respiration of yeast we have ever gotten. #BEoutstanding

STEM teachers. This is a great list of STEM competitions that your pupils could take part in. Thanks to Paul Williamson for the tip🙂community.stem.org.uk/browse…

This is mind-blowingly bad.Most up-to-date study on Atlantic Ocean currents system shows signals of collapse.This could happen in 2025-2095 with 95% probability. Land to grow wheat may drop by half. Winter temperatures in North Europe could drop between 10 and 30 °C. 1/🧵
New study: the Atlantic overturning circulation AMOC “is on tipping course”.
The paper by Dutch colleagues adds more weight to recent warnings, such as the OECD Climate Tipping Points report of 2022 and the Global Tipping Points report published 2023.

FUNGUS IN SPACE!!! 🍄🚀
Equal parts cosmic horror and nature being metal, let's talk about the lichen that grew on the OUTSIDE of the International Space Station!
Get your tea and curl up, because I PROMISE you wanna hear about these fungal cosmonauts 🧑🚀

Science teachers. If you haven't seen it before, this link contains pretty much all the resources you will ever need. 1000s of files. Thank you to Mr Clayson for collating

I saw someone post this activity a few years ago. Not sure who to thank but a nice little bit of investigative learning when teaching leaving cert biology about the villi in the small intestine for human nutrition #lcbiology

Look what arrived today! Grappling with Graphs is a super useful book and an essential purchase for every Science dept. In addition to the printed book there are superb digital resources too. Thank you Amanda and Karen 🙂 👏👏👏👏👏

One thing evident from the #PISA data is that allowing phones in the classroom is not good for student learning. Two things stand out:
1.Almost a third of students report being distracted by phones in class: “around 30% of students, on average across OECD countries, reported that, in most or every mathematics lesson, they get distracted using digital devices”
2.Even students who are NOT using phones get distracted by others who use them: “Equally important, around 25% of students indicated that, in most or every lesson, they become distracted by other students who are using digital devices, that the teacher has to wait a long time for students to quiet down, that students cannot work well and that students do not start working for a long time after the lesson begins.
