STEAM Café ski run 1
At the STEAM café, we now have a Lego ski run. This is made from Lego, which forms the bulk of the model.
The actual ski run parts appears to be just plastic, however the rest is Lego, and is quite heavy, white to represent snow, and green represents grass or other plants.
I took this photo on the way to work, later in the day the model is now complete, so I will take and share a 2nd photo, and share here and on Mastodon.
One of the uses of this will be to demonstrate the relationships between friction and surfaces.

Paper model DNA
Creating visual models can be very beneficial educationally, while you can do this using software and view in on screen, sometimes building by hand can be very beneficial, and perhaps therapeutic too. If you are studying biology then DNA plays a part in this subject, so building a model of the DNA molecule (or part of it) is useful PDB101 has a nice paper model of this, which we can look at building at a future STEM Group meeting at Paignton Library.
In the meantime you can still use Rasmol and OpenRasMol to visualise molecules and other structures.

Astatine as an anti cancer treatment
I found an interesting article entitled Astatine is a chemistry puzzle that shows anticancer promise so decided to try and build the molecule cited in the article from Molymods.
I am not too sure if I have done this correctly so am asking putting all the information here in the hope someone can perhaps help and advise further.
My main concern here is between the C6H4At – and N2 part, I have had to put in a carbon as I would assume the angle between the two indicates a carbon atom. This has left 2 Bonds free so not sure if I am meant to attach Hydrogen here.
So hopefully the above illustrates what I have built, so question is simply is this correct.
There is a thread on Science forums to discuss further here
