  1. Science Clubbing Young Engineers and Science Clubs Scotland Ice on the Moon

  2. Science Clubbing No 5Ice on the Moon How might the discovery of large quantities of ice in deep craters at the poles of the moon affect plans for the design of moon-base? This project, developed originally for the Pupil Researcher Initiative, provides opportunities for a wide range of scientific Investigation and technological problem solving …. Craters Solar Cells Ice melting Electrolysis Biospheres Rocket Science Satellite dishes …..etc

  3. Ice on the Moon Experimental Investigations 1. Craters – Diameter v Drop height, Flour scatter effect 2.     Melting Ice- effect of salt on Melting Point 3.     Curved reflectors – finding the focus 4.     Solar Panels – comparing output, linking to Capacitors 5.     Electrolysis – effect of different electrolytes, testing gases produced 6.     Seed Germination – using the Light Bank, comparing soils, growth rates 7.     Rocket Science –Newtons Third Law

  4. Ice on the Moon Technology: 1.Designing and constructing the Solar Melting Devices 2.Constructing Voltammeters 3.Making and testing mini-greenhouse 4. Constructing Solar Powered Buggies

  5. How it was tackled at Lenzie Academy Teams of 6 split into twos to share out the tasks

  6. About the moon…Focus on craters Expt 1: Diameter v Drop Height Use a sand tray and heavy ball* to investigate how the diameter of the crater is affected by the drop height (which affects the speed of impact) *not too bouncy! Expt 2 : Flour Scatter effect Put a small amount of flour at the centre of the sand tray. The impact of the ball will cause the flour to scatter, leaving tracks on the table. Investigate how these might be measured and how different objects creating the craters affects the patterns produced. SAFETY NOTE: Wear Goggles, don’t breathe in the flour and cover the table before you start : )

  7. Melting the Ice Expts : How does adding common salt affect the melting point of the ice? Is this affected by the amount of salt added? Do other salts have the same effect? Technology: Design a system to speed up the melting – can the ideas used in solar heating devices be applied here?

  8. Using Light & Solar Power Expt.1: What factors affect the output voltage from a photovoltaic cell? (a) area (b) angle (c) brightness of the light Expt 2:How can the electrical energy produced be stored? - experiment with capacitors. Expt 3: Demonstrate how curved reflectors bring light to a focus. How can you change the focal length? Research: Satellite dishes and their use in transmitting and receiving signals in space

  9. Electrolysys : Using a Voltameter Expt 1 : Demonstrate how to split the water into hydrogen and oxygen (Beware – if you added salt at the melting stage you might get another gas! ) How can you identify the gases produced?

  10. Electrolysys : Using a Voltameter Technology: Design and build a solar powered, plastic bottle voltameter to electrolyse the water.

  11. Lunar Biosphere Technology : Assuming you can use the oxygen to promote plant growth,use plastic bottles or baguette trays design a model biosphere. Expt: Investigate how the growing medium used affects the seed germination and/or seedling development. The plant experiments can be speeded up if you have access to a Light bank (Check with the Biology Department)

  12. Getting There:Fun with Rocket Science! Newton’s Third Law of Motion What does it tell us? How does it explain rocket propulsion? Experiment : with simple rockets Check out Catapulting Canisters* Technology: Paper Engineering Construct a launch pad for a 2litre water-bottle rocket *see next slide

  13. Rocket reaction rates Film canister rockets work well with water and denture cleansing tablets – but how much water, what temperature of water and what form of tablet give the fastest lift-off time? Use ¼ tablet each time Wear safety glasses, wipe up any spills

  14. Solar Powered Buggies Technology: Using equipment normally found in the club or at home, design and build a simple solar powered buggy which might function as a Lunar Rover. (Research models available to buy, then build your own !)

  15. Living in Micro gravity Research on line (NASA and/or ESA web sites recommended) to find out more about how reducing gravity affects astronauts in Space. Complete the project by preparing a Showcase display, including the following elements • A clear statement of the aim(s) of your project • Highlights from the research you carried out • Investigation Reports for your experiments • Technology Reports for your ‘model solutions’ • Photographic evidence and or power point presentation
