New post from TheSciEd Distillery! Over 90% of students in one study thought that if you react a blue substance with a yellow substance, the resulting product would be green. Overcoming this requires a shift from additive to emergent thinking. thescieddistillery.blogspot.com/2025/03/comp...

Compounds: The importance of emergent thinking

I am seeing lots of online sources categorise bending/cutting as physical changes. The curriculum focus here at age 9-11 is only on reversible changes of state/ mixing/dissolving but should bending/cutting be included as irreversible physical change? Where can I find a trustworthy definition?

Hi BlueSky - I'm doing a mock interview for a student applying for biomedical engineering at Imperial. This is outside of my expertise so would appreciate ideas/inspiration/questions. Any idea what the interview would focus on?

Latest post from the SciEd Distillery. Do all your students understand how far air pollutants can move? This understanding is critical to comprehending increases in carbon dioxide levels in the atmosphere. thescieddistillery.blogspot.com/2025/01/move... #ChatChemistry

I am currently writing some resources linked to the mole and quantitative chemistry. It has got me thinking. Is there a hidden curriculum that should lie behind the assessed curriculum? A specification only details the latter.

You hear about fiction authors being guided by their characters. Today I started writing a resource on relative atomic mass and it has become one on molar mass. Not sure you can be guided by chemistry as an author but it is feeling like it...

Whilst I am trying to keep this channel exclusively for professional posts about science education I did want to share a little musical something at the start of the advent season and welcome my choir to BlueSky!
