Dippy the Dinosaur and Perfume Making

We were grateful to be invited to spend a day with Dippy the Dinosaur in Kelvingrove Museum, Glasgow, as part of the Geological Societies day.

Some of you might be wondering who is Dippy? Dippy is a Diplodocus found in America. The replica of the dinosaur came to the UK after Edward VII saw a sketch of the skeleton in Skido Castle, Scotland, in 1902 and Andrew Carnegie, founder of the museum in America that Dippy stayed, made a plaster cast for the King. He is made up of 292 bones and is 21m long. He ate plants and moved on large trunk-like legs.

Our Geopark representatives and volunteers were warmly welcomed by the museum visitors, with lots of people learning about Lochaber’s geology and fossils.

Dippy is in Kelvingrove until May 6th 2019, we recommend you go and see him on his tour!

 

At Caol Primary’s STEM committee, last Friday, Lochaber Geopark’s STEM ambassador had been asked to teach perfume making, as part of British Science Weeks activity pack.  Perfume bottles, pipettes, essential oils and olive oil… were all used in the ‘mini factory’.

When perfume was first made it was produced with the same ingredients that we used, unlike the alcohol that is the base of perfume today (which makes it evaporate quickly). It originated around 2000BC, in Egypt and Cyprus, and was used in ceremonies, using local herbs and flowers.

The result from the group’s perfumes: some fragrant perfumes, and some pungent! The aroma from different herbs varied in strength. We wanted to see which essential oil was the strongest smelling and it turned out to be Thyme. We discussed these topics in relation to perfume:

  1. The strength of smell
  2. The history of perfume
  3. The science behind the extraction of smells
  4. The link between smell, your other senses and memory experiences

Thanks to Caol for a great STEM session!
