Year 5/6 have been doing experiments to try to recreate a volcanic explosion. All Children had a go at the Vinegarcano experiment and then Mr Holmes from Secondary demonstrated some other experiments.

Vinegarcano experiment

What you need:

warm water
food color
vinegar
baking soda
flour
liquid dish

science glass
conical flask
wooden mat
beaker
funnel

 

How to make a vinegarcano

  1. First get warm water and pour the water into the tray.
  2. Get the liquid dish and pour it in the water then mixed it together.
  3. Pickup the wooden mat and put it on your table and get the conical flask then put it on the wooden mat.
  4. Pour the water that mix with the liquid dish into the conical flask.
  5. Picked the flour and get the spoon then you put 3 spoon of the flour into the conical flask then shake it but don’t shake it too hard.
  6. Put the baking soda into the conical flask but put the baking soda just only and shake it but not too hard.
  7. Mixed the vinegar and the food color in the beaker and use the red food color and mixed them in the beaker.
  8. Get the funnel then put it inside the conical flask but just only into it little bit then get the beaker and in the beaker is the vinegar and the food color and pour it but not too much and it will erupt.

Vinegarcano Experiment

What I saw:

As I poured the vinegar in, bubbles were starting to come up from the conical flask. As I poured more in, it went higher. More bubbles were starting to be created up to the top. It went flowing down the conical flask just if it was a volcano.

How much did it look like a volcano?

       It looked just like a volcano because the vinegar mixed with the food coloring looked like lava flow.

Melting Magnesium


What you saw:

First Mr Homes got something out and when he turned it on, the fire lit up, it became darker blue. I saw Mr Homes burning the magnesium which is a piece of metal, it was very bright! So bright that we have to look away! Then it stopped, when we look at it again it already turned into ashes.

How much like a volcano do you think it looked?

I don’t think it looked like a volcano because, it’s not a shape of a volcano, it didn’t explode and it’s only bright. It’s nothing like a volcano.

Volcano expansion

What you saw:

I saw Mr. Homes get 10 grams of ammonium dichromate; the ammonium dichromate was a bright neon orange colour. He put the ammonium dichromate into a fume cupboard that had so many different types of chemicals in tins and boxes. He placed the ammonium dichromate into a metallic tray. Mr. Homes stood a little piece of a stick in the top of that little neon orange pile. Then he lit the top with a long lighter. We waited for the fire to go down the stick very slowly. Suddenly, just like popcorn, the ammonium dichromate started popping, the lovely neon orange colour turned olive green.  The olive green bits looked bigger than the neon orange bits were.  The small neon ammonium dichromate was a small orange volcano, now it’s a big green volcano.

How much like a volcano do you think it looked?

The orange ammonium dichromate was in a small volcano shape. Then the olive green bit grew just like a volcano would, but only faster. The olive green bit was also in a volcano shape.

Screaming jelly baby experiment

What you saw:

I saw Mr Holmes drop the gummy bear’s with the tongs in the test tube with the potassium chlorate inside it  then the test tube spits out lot’s of sparks and puffed load’s of smokes and they were flowing to the top.

How much like a volcano do you think it looked like?

It looked a bit like a volcano because the smoke was puffing  out of the test tube and the sparks were shooting up to the top, and the explosion was really violent like a volcano.

Year 5/6 also created animations to show what a volcanic eruption looked like. The pictures were drawn using word and then turned into an animation using Windows Movie Maker.
