MAKING YOUR OWN VOLCANO!

This week we made our own volcanoes!  I bet you never knew you could have a volcano in your own classroom!  Well it is quite simple if you carefully follow the instructions below.  But be warned - this can get messy so make sure you wear an apron or old work shirt before beginning.

YOU WILL NEED:

A large dish/tray

Sand and gravel

A plastic bottle/jam jar

1/2 cup of water

Liquid hand soap

1/2 cup of Sodium bicarbonate (baking soda)

Vinegar

A jug

Red or orange food colouring

Few table spoons of flour

INSTRUCTIONS:

1. Begin by taking your bottle or jar

2. Add the water to the bottle/jar using a funnel or jug

3. Mix the baking soda and flour together and add to the water

4. Add the liquid hand soap (about 5 or 6 tablespoons) 

5. Add the red or orange food colouring

6. Mix everything together.  If using the bottle put the lid back on and shake it all together.

7. Place the bottle/jar on the middle of the tray

8. Pack sand and gravel around and build up into cone shape (the volcano)

9. Measure out 1/2 cup of vinegar

10. Add vinegar to the bottle/jar

11. Wait for the eruption to begin!

DID  YOU KNOW:  When you mix the vinegar and the sodium bicarbonate (baking soda) together it causes an acidic reaction.  This is the reaction you see when the volcano erupts.  This reaction makes a gas called carbon dioxide.
