I have been working with year 5, researching and making some of the exhibits for the Digging Deeper Museum.
We started off in January doing some observational drawings of rocks and fossils using pen and ink. We looked at the shapes and textures of the specimens we were drawing, and drew in pencil first, adding detail in ink using nib pens and brushes.
I am going to frame these drawings so they can be put up in the museum.
We also worked on a 'fossil wall' or 'fossil bed' using clay and plaster of paris.
These pictures show how we made the fossil bed.
The first job on Thursday was to flatten out some clay to make a large square-ish slab of clay to work on.
Then we carved and modelled fossils out of the clay in relief. You can see from the photos that some of the fossils are sticking up on top of the clay and some are hollowed out of the clay.
The next stage was to build cardboard walls around the clay, in order to stop the plaster from oozing everywhere.
We then mixed up the plaster (this was quite messy!) and poured it on top of the clay. We let the clay set overnight.
On Friday afternoon we removed the clay from the plaster cast. Our fossil bed was revealed! We spent some time cleaning any odd bits of clay from the plaster.
A few weeks later we painted the plaster cast with PVA glue - this was to seal the plaster, so it wouldn't absorb too much paint when we painted it. We let the PVA dry then mixed up a yellow ochre/brown-ish colour from acrylic paints, diluted it with PVA and water, and painted it over the whole cast.
This last photo shows the finished result - I think it looks fantastic!
Miss Riddall's class was brilliant to work with - I have really enjoyed my Friday afternoons and I'm looking forward to the museum day on 7th March.
