The Department of Physics and Chemistry of IES Valle del Saja recently delighted us with an excellent thread 🧵 about “10 things you can do, study or reflect on in the classroom":

Thanks to the Department of Physics and Chemistry of IES Valle del Saja for providing me with the original videos.

Table of Contents

1. Silver Mirror

2. Flame Spectra

Suitable ions, methanol, flame 🔥 and… fireworks 🎆🎇.

More information here.

3. Copper Nitrate Fountain

Chemical reactions cause variations in concentration, temperature or pressure that allow to generate bright and colorful fountains ⛲.

4. Golden Rain

Some precipitates are so spectacular that they almost turn them into works of art.

5. Spectra in Discharge Tubes

Another search for color and for deciphering the bar codes hidden in each radiation.

6. Luminescence

Fireflies? Algae? Luminescent phenomena are always the most evocative.

7. Galilean Thermometer

With a design of more than 350 years, just like that. It connects us to the essence of liquid buoyancy and expansion.

8. Newton’s Cradle

A very well known device that does not prevent new studies every year that are equally interesting.

9. Siempre fuimos nómadas (in Spanish)

Dramatizing passages of science, like the best Sagan here, is something that usually works very well with students.

10. Instants

All those moments of emotion that were lost with the pandemic are collected here in instants of other years.
