Everything around us has changed at least a little since yesterday. In nature, a tree has grown a little, a flower blossomed, bees have made new honey, a cloud has disappeared, a bird has sung… Even the things we can’t see change, but it does not mean we can’t find out about these changes.
Lara and Tina are curious, imaginative and always happy to learn something new.

Let’s find out new things together with Lara and Tina! What happens when we put sugar in water? What should we do to make a candle not burn out? How can we hide a coin in salty water? How can you tame an egg? We can learn more about all these things if we find what we need and do an experiment. At the beginning, we will ask questions, and then we will look for answers. It will be quite an adventure!
Lucas knows stories that hide questions, and Mary knows many answers.

Ice Bars I love when ice is like a thin shell. I can nibble at it!

fter many snowy days, a sunny morning dawned. The window was so bright, as if spring had come. But the next day it was cold again, and everything looked different. Ice bars appeared on the window, and the sun couldn’t be seen anywhere.
Where did the ice bar on the window come from? You will find that out when you do the experiment on the next page. 4
Tina, look! The ice in my glass is also slowly melting!
Since you’re mentioning ice, I’ll tell you what happened last winter.
will need:
water, a few cubes of ice, a little saucepan, a lid, a cooker, help from an adult.
2. Pour some water in the saucepan and
heat it on the cooker. When the water boils, it will turn into steam.
1. Put the ice into the saucepan, heat the saucepan slowly, and observe. The ice will turn into water.
Steam turned into water on the cold lid.
3. Heat some water in the
saucepan again. Put the lid on the saucepan after the water boils. After one minute take off the lid. There will be drops of water on the inside of the lid.

this too: rn There are three states of mater of water in nature. The state of matter in which water will be depends on the temperature. When the sun shines, ice begins to melt. When you put a bottle filled with water in the freezer, the water freezes. 5

Puddles remind me of what happened in the park the other day. Don’t you remember?

will need:
two glasses, water, sugar, a teaspoon.
1. Half-fill one of the glasses with
water. Add a spoon of sugar in the water and stir it. The sugar will dissolve in the water.
2. Half-fill the other glass with water. Add some sand and stir it. The sand will not dissolve in the water.
L ea
Sand is heavier than water, which is why it will fall to the bottom of any water filled container.
this too: rn Sugar dissolves in water easily. Sand does not dissolve in water. If you filter the water which contains sand, the water goes through the filter while the sand remains on it. This means that things that do not dissolve in water can be easily separated from it.
