On melting ice cubes and molecular diffusion of heat
First of all, let me say how much I love having chats like the one Elin and I had over the weekend (which you only see the very beginning of…
Ice cubes melting in fresh water and salt water
Today we are doing the melting ice cubes experiment in fancy glasses, because Elin is giving a fancy lecture tonight: The Nansen Memorial Lecture of the Norwegian Science Academy in…
Experiment: Ice cubes melting in fresh water and salt water
Explore how melting of ice cubes floating in water is influenced by the salinity of the water. Important oceanographic concepts like density and density driven currents are visualized and can…
Melting ice cubes experiment — observing the finer details
If you don’t know my favourite experiment for practically all purposes yet (Introduction to experimenting? Check! Thermohaline circulation? Check! Lab safety? Check! Scientific process? Check! And the list goes on…
Teacher training at Lotseninsel
As I mentioned yesterday, I recently contributed to a teacher training on Lotseninsel, a tiny island on the Baltic Sea coast. The training was run by the Ozean:Labor of the…
Melting ice cubes & thermal imaging camera
I haven’t talked about my favourite experiment in a long time (before using it last week in the MeerKlima congress and suddenly talking about it all the time again), because I…
My workshop at MeerKlima.de
Today I ran a workshop at the MeerKlima.de congress in Hamburg: A congress for high school students, organised by a student committee. The large lecture theatre of the chemistry department at…
Workshop prep and a riddle
Looking at the picture below, can you guess which experiment I am going to do at the MeerKlima.de workshop? Yep, my favourite experiment — melting ice cubes! :-) And I am…
Considered exemplary: My “ice cubes melting in fresh water and salt water” in the “on the cutting edge” teaching collection! :-)
After reading recently that I am being considered the queen of the melting ice cube (aaaaw, thank you!!!), having my movies of the experiment featured in Elin Darelius and Petra Langebroek’s article…
Using the “melting ice cube” experiment to let future instructors experience inquiry-based learning.
Using the “melting ice cube” experiment to let future instructors experience inquiry-based learning. I recently (well, last year, but you know…) got the chance to fill in for a colleague…
Oceanography PBL workshop and case
My awesome colleague Marisa ran another workshop on Problem-Based Learning (PBL) in which I was lucky enough to assist. For the last workshop for people who are planning to use PBL in their…
Ice cubes melting at the bottom of the beakers
Because surely there is one more post in this topic? ;-) For those of you who haven’t heard about the “melting ice cube” obsession of mine, please check out the…
Why folic acid might be good for people, but not so good for tank experiments
I had to do the complete series of experiments, of course… The other day I mentioned that I had used salt from my kitchen for the “ice cubes melting in…
Melting ice cubes, again
Somehow I am stuck on this demonstration! I can’t let go of this experiment. Last time I posted about it, someone (Hallo Papa!) complained about the background and how I…
Conducting experiments at EMSEA14
Kristin’s and my workshop at EMSEA14. As I mentioned before, Kristin Richter and I are running the workshop “Conducting oceanographic experiments in a conventional classroom anywhere” at the European Marine Science…
Melting ice cubes reloaded
Or why you should pay attention to the kind of salt you use for your experiments. The melting ice cubes in salt and fresh water is one of my favorites that…
Guest post: The mystery of the cold room
Guest post by Kristin Richter! Today I’m excited to bring to you a guest post from Innsbruck, Austria, written by my friend Kristin Richter. Kristin ran the oceanography lab in Bergen…
Dangers of blogging, or ice cubes melting in fresh water and salt water
When students have read blog posts of mine before doing experiments in class, it takes away a lot of the exploration. Since I was planning to blog about the CMM31…
Melting ice cubes – what contexts to use this experiment in (post 4/4)
What contexts can the “ice cubes melting in fresh water and in salt water” experiment be used in? As you might have noticed, I really like the “ice cubes melting…
