This experiment is a fun and delicious way to see how an aquifer works.
[Voiceover – student]: Today we're going to make our own aquifer.
What we need to create our aquifer is: a clear plastic cup, ice cubes, some ice cream, sprinkles, food colouring, lemonade and a straw.
Start by placing some limestone into the bottom of your aquifer, about halfway will do.
[Student adds icecubes to a tall glass, about half way up]
Next we need to add some topsoil to our aquifer.
[Students adds a scoop of vanilla icecream to the glass]
We also find things like dead leaves, earth worms and other organic matter in our topsoil, so we need to include them in our aquifer.
[Student adds coloured 100s & 1000s sprinkles to the glass]
Unfortunately we also find pollutants like fertilisers, herbicides, pesticides, oil and petrol in our aquifers.
Add these in the form of food colouring. Just a little as it goes a long way. See how it filters down contaminating all the layers.
[Students adds a few drops of red food colouring to the glass, which starts to run down the other items]
Be careful not to add too much as it will make your groundwater unusable.
[Students adds a few drops of green food colouring to the glass]
Now all we need is for it to rain - but not too heavy!
[Student pours lemonade on top of all the items in the glass]
Now we can go ahead and extract our groundwater through a bore.
[Student selects a coloured straw from a packet]
Sink your bore pipe, attach your pipe and start extracting.
[Student starts to drink using a straw to 'extract' the liquid]
