Here is the 2nd page I did for my class over at ATDML for March's virtual crop. There is a template for the heart that you can paint around, and then the rest is quite straightforward - just lots of layering and embellishments.
The photo is from the lunch area in the Natural History Museum on one of our many trips to it (I love it!) and my kids love a selfie opportunity too. We went to the Museum as they have recently opened up the new Earth Zone with the earthquake machine and loads of hands on experiments to have a go at to explain lots of the science behind our planet.
There is one more page that I made with the kit - if you haven't downloaded the instructions, then here is a link.
