1. How might we protect ourselves from volcanoes? Put a lid over the top of the volcano Put heat and smoke detectors on top of mountains – and set up an early warning system Build a big moat around the volcano Divert the lava flow using channels, dams and walls Build super high powered fire extinguishers and a fire service staffed by robots Design special protective clothing for people living or going near volcanoes

2. How might humans live on Mars in the future? Design faster rockets (so that the journey takes 7 days not 7 months) or invent time travel Use a workforce of robots to build a city on Mars for humans to live in Build a pipeline all the way from Earth to Mars to transport food, water and oxygen Land a space station on Mars and explore the planet from that Design special suits for people to wear on Mars that generate oxygen to breathe Search Mars for water – look underground

3. How might we explain what the world would be like without rock? No fossil record – no knowledge of dinosaurs and evolution Need a new covering over the Earth – to protect us from boiling magma Mainly wooden housing (risk of ‘great fire of the world’). Have to rebuild Rosendale No coal and oil The natural environment would look completely different – no hills and mountains, no rocks in gardens No roads and pavements We would have to do without all sorts of everyday things – pencils, chalk, medicines, jewellery and much more

4. How might we learn from the extinction of the dinosaurs to safeguard our own future ? Use other planets and moons to block a meteorite heading for the Earth Fire a rocket into a meteorite heading towards Earth to send it off course Make sure that we do not pollute and poison the environment Could a giant sea monster (as we read about in myths) jump out of the water and swallow a meteorite before it crashed into the Earth? Build underwater cities to live in if the environment above sea becomes too polluted Build a protective shield over the Earth
