Today we had a brilliant time making our very own volcano explosions!! We discussed what we already knew about volcanoes as a class and watched a video clip of one erupting. We made a class word bank of words to describe volcanoes. Then we predicted what would happen when we mixed vinegar and baking soda in a bottle. Lots of us used our kowledge about volcanoes erupting to guess it might explode, because we thought the vinegar might make it fizzy.
Wow! We couldn't believe how many bubbles it made. The bubbles pushed the vinegar out of the bottle and got Miss Coleman!! We thought the vinegar looked just like the lava erupting from
a  volcano!
