Description of the experiment:

The children and I decided to use the purest water for our essential oil diffuser-vaporizer.

We decided that it would be best to use the water that we collect from the gutters when it rains.

However, looking outside, we saw that our water was frozen.

We thought and decided that we would melt a piece of ice by warming it with our hands and leaving it warm in our room.

After a while, we saw that the ice had turned into water.

We poured the water into our diffuser, added eucalyptus oil, and refreshed and disinfected the air in our room.

I explained to the children that the diffuser also turns water into steam by heating it.

Description of the experiment

Ricky, the little ant, visited our kindergarten and asked for our help!

One day, when he had left his little house, he forgot the door open…

Unfortunately, that day it rained heavily, and water entered Ricky’s house, specifically into his food storage room. It was freezing cold, and everything froze solid…

Now, all the seeds and nuts he had gathered throughout the summer are trapped in the ice…

He came to us for help… We had to find a solution!

The children eagerly agreed to help Ricky thaw his food and came up with various ideas!

They placed one piece of ice on the radiator, inside a bowl.

They sprinkled salt on a second piece of ice.

They decided to place the third piece of ice next to the window so it could be exposed to the light.

We made predictions! Which piece of ice would melt the fastest?

By general consensus, the children believed that the piece of ice placed on the radiator would melt first!

We observed the melting of the ice at regular intervals…

Indeed, our predictions came true!

First, the piece of ice on the radiator melted, then the one with the salt, and finally, the one by the window (note: there was no sunlight that day).

Now it was time to feed Ricky, who had been waiting eagerly all this time!

Solid state 

We filled balloons with water and placed them in the freezer. The next day, we saw that the water had turned into ice. We held a frozen balloon in one hand and a balloon with water in the other and discussed their differences. The frozen balloon was cold and hard, while the other one was soft.

liquid state 

We removed the ice from the balloons and divided it into four plates. We placed one in the fridge, another on the radiator, a third on the windowsill (it was a sunny day), and the last one in a random spot in the classroom. After about half an hour, we observed that the ice on the radiator had completely melted, the ice on the windowsill had melted less, the ice in the classroom even less, and the ice in the fridge almost not at all.

Gaseous state

While we were waiting, we poured water into two glasses. In one of them, we added ice cubes. We stirred it and observed that the ice cubes melted in the water. The children dipped their fingers into the glasses and noticed that the water with the ice cubes had become very cold.

Next, we boiled water in a small pot. We observed that as the water heated up, steam began to rise. It evaporated. Then, we poured the water into a jar and covered it with transparent plastic wrap. As the steam rose and touched the plastic wrap, it turned into water droplets.
