Jaden, Kamira, Cebo and Digace end our experiment orals

My class has just loved our experiment orals, they are very sad that we  had our last three on Friday.


Jaden started off by showing us that salt water can conduct  electricity and light up a
 light bulb.

Demonstrating how to connect
the wires to the battery

 

Add a lot of salt to the
water and stir.

And there you have it..
another successful
experiment.

Next was Kamira. Her experiment proved that oil is lighter than water and food colouring is heavier. She did this by making underwater fireworks.

Kamira was so well prepared and explained everything so clearly. A fantastic effort, well done.

Pour oil into a dish

Scatter drops of different
coloured food
colouring into the oil.

Mix a little with a fork,
 so that the particles are
not broken up too much.

A fantastic display of
underwater fireworks!

Cebo showed us how to make chicken noises using a cup and string. It showed us that sound vibrations travel along the string. The cup intensifies the sounds.

Explaining exactly
how to set up the
experiment

Pull the string..
listen for the chickens!

Last was Dighace. She showed us how to make a volcano. She started off by giving us some general knowledge on volcanoes which was interesting.

Put in some bicarb

She used a mixture of
tomato sauce and vinegar
and poured it in.

Everyone was so
excited when it
erupted.

Thank you parents for your help with all our experiments. They would not have been possible without your input.
