Larva Scientist gets too close to Lava – youtube Scientist gets too close to Lava
Hokey Pokey Recipe 5 TBS sugar 2 TBS golden syrup 1 tsp baking soda Bring sugar and golden syrup to the boil slowly stirring all the time. After it starts to foam up, simmer gently over a very low heat for 4 minutes, stirring occasionally and still watching it carefully. Remove from heat and add baking soda quickly until it foams up Pour at once into baking paper.
Lava structure? What is it about the structure of lava that is quite unique? How is the hokey pokey structure the same?
Igneous Rocks Igneous (Ignite) – ig·ne·ous Adjective: 1) (of rock) Having solidified from lava or magma. 2) Relating to or involving volcanic processes: "igneous activity". Igneous … think ignite … think fire … think lava or magna
Igneous Rocks Igneous rocks are formed through the cooling and solidification of magma or lava. Igneous rocks may form either below the surface as intrusive (plutonic) rocks or on the surface as extrusive (volcanic) rocks.
What is the difference between magma and lava? Magma is the molten material beneath the Earth's crust. This material consists of rock, gases, and mineral The temperature of the magma can be as high as 5000 degrees. Lava is the molten rock that comes out of a volcano or from a crack in Earth's surface. The molten rock comes from the underground magma. Lava is just magma that has broken through Earth's surface.
Activity Draw the structure of the earths core. Show the magma An example of lava The Earths crust The Earths inner and outer core. Extra challenge …. Can you draw it to scale! Crust – 5-50 kms Mantle – 2900 kms Outer core – 2250 kms Inner core – 1200 kms Mt Everest – 8.4 kms
