The Unbelieve-a-Bubble Science Show with Emma

Emma was very funny.  To begin with she put water on her hand and then put soap bubbles on her hand.  Then she lit her hand on fire!  We think she had some flammable gas inside those bubbles.

Initially, she made medium-size bubbles.  We tried to make different shaped bubbles using a star, square and a heart-shaped thingamegigy.  But they just made sphere-shaped bubbles.  She made massive bubbles using a big bubble thingamajigy.

She made bubbles using soap mixture and helium and they went straight up to the roof and popped.

Fallan learnt that there are four bubbles on a car.  So if you came to school in a car you were riding on bubbles.  

Devon, Mele and Idika took part in an experiment to see if they could trap carbon dioxide - from a fizzy tablet (effervescent).  They put some water in a little container with part of an effervescent tablet and put the lid on.  They shook the container and put it on the table.  The one Emma did exploded.  The ones the girls did, needed a little bit more of a shake by Emma but they did explode.

Emma taught us that a bubble is just some gas trapped inside something.  A balloon is a bubble.  She filled a balloon with air and then she let it fart.  Emma then filled a balloon with helium and she lit it on fire.  It popped like a regular balloon.  She lit the giant lighter again and set the other balloon on fire.  It made a flame explosion.  This balloon was filled with hydrogen.

We learnt more about how science is all around us and we are all scientists.   We all enjoyed the show!

Creating a Volcano using Playdough

 Today we created playdough volcanoes, using baking soda and vinegar eruptions.  We taped a plastic cup to a piece of cardboard and put baking soda and vinegar into the cup.  After it had "erupted" we marked where the "lava" had flowed to.  We dried up the "lava" and placed a layer of playdough over where the lava had been.

We then erupted our volcano with more baking soda and vinegar.  Again once it had erupted we marked where the "lava" had flowed to.  We dried the "lava" with paper towels and placed a layer of different coloured playdough over the area the "lava" had flowed.

We then erupted our volcano one more time and marked where the "lava" had flowed.  After drying the "lava" we used another different coloured playdough to cover the area where the "lava" had been.

This enabled us to make a volcano with three different layers of lava.  We then used clear straws to take a core sample of the volcano - just like real scientists do!
