Sustainable impact by design
The STEM Equals Summer Scheme won funding to mark COP26, and so ten Strathclyde staff members were able to work with diverse young people in Ayr and Girvan over five days of STEM (Science, Technology, Engineering and Mathematics) activities, talking about their research and how it can limit climate change.
We had a lot of fun!
Part 1: Lithosphere
Today, the construction sector represents one of the main contributors to the carbon global emissions. Conserving existing buildings represents a more sustainable future.
How sustainable is stone?
We looked at pictures of monuments, and matched the samples of stones under the microscope with the building based on their colour.
Solar cells
Aruna’s work looks at how we can make better solar panels, which will let us make electricity without burning fuel. She showed us how to use juice from berries to make solar cells and, to our surprise, they worked!
Managing electricity
Hong showed us how to make circuits that would control the electricity made in different ways, so that we always have electricity when we want it.
Part 2: Atmosphere
If we pollute the air, animals and plants will die, so this isn’t sustainable. Rui and Agusti showed us how air currents can be used to make electricity. Rockets, like the ones we made with Christie but much bigger, can be used to investigate the atmosphere high above the Earth.
Which bottle rocket will fly best?
We made bottle rockets using water, vitamin C and Seltzer tablets. We tried mixing them in different amounts and placing them differently so they would fly well.
Making electricity without air pollution
We introduced how the offshore wind power is generated, transmitted, and supplied to households to light bulbs. We emphasized what we can do to tackle climate change to encourage children to engage in renewable technology.
Engaging in renewable technology
We helped students understand why we need modern technology to control the wind power.
Part 3: Hydrosphere
Hydrosphere means all the water on, and in, the Earth. This includes seas and rivers, and water in air like clouds and rain.
Water turbines
We made water turbines, which can be used to create electricity with the power of water.
Cola volcanoes
The cola experiment showed us how gas can be pushed out of liquid very quickly.
Did it work?
Giving out carbon dioxide
This is what happens in volcanoes and also happens in the sea as it warms up.
Part 4: Biosphere
We went to Dumfries House and looked at different living things (moths, lichen plants) that are affected by pollution. If species are killed by human activity, the planet isn’t sustainable any more.
Bio-indicators: moths and lichen
Moths and lichen are bio-indicators, which means that they can show us the quality of the air around us. We determined that the air in Dumfries House was clean!
Worms
Listen to Dr Margaret Cunningham explain how they experimented on different types of worms and the optimal environments for the blackworm which survives in water.
Painted stones
The learners tested their skills at rock painting with messages of sustainability. One of the highlights of the rock painting session was discussion on the theme each learner had chosen to paint on their own rock – for example, the sustainability of Harry Potter and his broom vs driving a car!
Conclusion
The student voted for the most sustainable character in the stories, and left a drawing or note for future students in a time capsule.

Sustainability award voting
Should Queen Biosphere should win the sustainability award because her tower produced flowers for the bees, as well as fruit to feed people at Culzean Castle, or should Thomas the servant win because he recycled rubbish, and re-used it to make useful things like a pen-knife?
