We are doing lots of fun experimenting in science this term.  Today we made some volcanoes just like the ones we have on Earth and Venus.  First we thought about what we knew about volcanos already, some of the children said they explode and have lava and some of us new the tricky words extinct and magma.  We weren't sure what the lava and magma was and whether or not Elephant hill and Chapel hill were volcanoes so the children have a little challenge to find out the facts, we decided books, the internet or asking an adult might find us the answer.
We all worked together to make the first volcano and put in half a teaspoon of baking soda and a mini cup of vinegar. We were all really excited when the volcano starting fizzing and bubbling.  The children then had to think of their own 'What will happen if ...' questions and carry out their own experiments in small groups.  Here are a few photos of our little scientists in action.  Some of the children decided they were going to make their own volcanoes at home so I've posed them my own question ' What would happen if the vinegar is warm?'  Please let me know if you find out the answer!
