Worksheet: Pressure in a Fluid (Year 9)
Lots of companies around Newcastle build machinery for the offshore industry – footings for wind turbines, robots to lay or inspect cables, and more. Testing machines designed to be used underwater isn’t just a case of dunking them in water. You also have to think about pressure. This worksheet takes students through concepts and calculations about pressure in a fluid, and introduces local engineering company Tyne Subsea, whose hyperbaric chambers are used to test underwater machinery.

This workshop is about observing, predicting and testing the world around us. It is about discovering the power and beauty of volcanoes: exploring their features, thinking about how one volcano differs from the next, and finding out what the limits of our knowledge are.
NUSTEM is fortunate to have a resident volcanologist – our technician Sarah, who’s travelled the world studying volcanoes. Above are some of her photographs, and in the the workshop you’ll talk to Sarah about her work.
To understand the behaviour of volcanoes you need to know about how different materials flow. One experiment we do is to pick a range of liquids, like water and golden syrup, and compare how they flow down a slope. How do you describe what you see? Is there something you can measure? How reliable are your measurements?
Another way of exploring and compare how liquids flow is to blow bubbles through them, as demonstrated in this photograph from our launch event.
The workshop also includes handling and studying samples of volcanic rocks.

One straightforward activity is to explore some currently-active volcanoes. We put this map together of just some of the volcanoes which were doing their thing in February 2015. Click or tap the markers for more information and links for each volcano.
If you’d like a full list of active volcanoes that’s kept up-to-date, there’s a wealth of information over at the aptly-named Volcano News.com.
BBC Earth has some excellent video clips of volcano eruptions and information about Supervolcanoes to follow up on, if volcanoes are a hit.
Stuff flying through the air is always fun. Unless you’re the owner of the priceless vase which happens to be in the way of the otherwise-graceful arc, but that’s obviously not going to happen to you, right? You’re more careful about aiming. Ahem.
Even better is making things you really really don’t like sail through the air with the greatest of east. Above, TV presenter Greg Foot dons his best festive jumper and uses a vacuum clear to hurl his hated brussels sprouts as far as possible. This sort of vacuum bazooka is a classic thing to make, and while it can be a bit fiddly it’s well worth having a go if you’re feeling bored over Christmas.
If you’re really ambitious, you might end up completely obsessed with the things, like our chum Dave Ansell:
Or, if you fancy something a bit simpler, our partners the Centre for Life have a not-quite-the-same-but-similar-results demonstration:
Merry Christmas. And do try not to put anyone’s eye out with flying objects.
