Volcano eruption

 Hello,

today we will simulate a volcano eruption.

We made a volcano using a Volcanova model, but you can use plastic bottles if you don't have the model.

 We used:

• a volcano model
• sand
• plaster
• water
• a spatula
• paint brush
• colourant
• a spoon
• vinegar
• sodium bicarbonate
• plastic bottles
• connecting tube

We mixed the plaster with the sand and water to build the volcano. Remember to mix it little by little or it'll dry out and you'll have problems. 

The reaction between vinegar and bicarbonate produce bubbles and allow to simulate the liberation of gases and lava in the true volcano.

We added yellow colorant to the vinegar, but if you add a red one it will be more realistic.

We hope you like our video

See you soon.

Solubility experiment

I present you a simple experiment to demonstrate the solubility of different substances. This experiment will help us to see if some materials are soluble in water applying the scientific method.

The substances that we use are:

nailvarnish

icing sugar

rice

cotton wool

instant coffee powder

tap water

We also need the following lab (or kitchen) utensils:

measuring jug

5 glasses

teaspoon.

I formulated my hypothesis and you can see in the video the results.

Potato regeneration

Today we'll regenerate potato plants from parts of potatoes.

Did you know that for avoiding potatoes to grow little roots you have to put it in the same bag as an apple? Apples release etilen a substace which stops the roots growing.

But, today we will use potatoes from vegetative parts of the tuber so we need some that did not stay close to any apple. When are old, potatoes start to grow roots to regenerate themself. After using the potatoes for cooking, we can use part of the peelings to regenerate the entire plant.

You will need:

• a grid or a net
• a container to fill with water
• old potatoes

Watch our video to discover how we did it.

As you can see, it's important that the potatoes are covered with a thin layer of water specially during the first days, until the roots grow. After the roots come out you don't have to worry about the lack of water because they can submerge in the water in the container underneath.

Also we could see how an opaque container could be better for growing taller plants.

We hope you like our potato project for gardening.
