The Scientific Method 10
Experiments are the basis of science, but for them to be used as valuable data, they must be done following a proper method!
First, you must start with a question and think about a possible answer. The experiment will serve as a confirmation of your idea. A proper experiment should be prepared and observed very carefully, to note the result.

If the experiment proved your answer was correct, you can continue your discovery, or else you can rethink your experiment or your answer to the initial question and try again.

Homemade crystals While crystals like diamonds or other jewels are extremely precious, you can grow your own crystals at home

Boil some water in a pan. Have an adult helping you in this step.
Cut the thread. It must be longer than the depth of the glass, you can adjust it later.
2
Drop some food colouring in the water and stir it.
5
Tie the thread to a pencil.

Add sugar until it doesn’t dissolve anymore and some of it remains on the bottom of the glass
Immerse the thread in the water and leave it for at least a day.

How does it work? Crystals are solids formed by a regular pattern of molecules connecting together. When sugar is dissolved, the molecules are separated in water and, as it evaporates, they fall naturally into their place in the geometric structure.

If you want your crystals to grow further, prepare another solution (steps 1 to 3) and reimmerse the thread again.
The form of the crystals vary depending on the substances they are made from. At home you can also try to grow them from salt or baking soda, following the same process. Can you spot the differences?
Energies in action! Energy is all around us, in many forms, but we can’t see it. Find out where it’s hiding with the following experiments!
Cabbage Magic 112
Cabbages may not be the most delicious food in the world, but some of them have magical properties ‌

Ask an adult to chop the red cabbage into small pieces.

How does it work? The same chemical that gives the cabbage its purple colour is able to detect whether substances are acids or bases. When it comes in contact with acids it turns purple and green with bases. You can create a whole palette of colours experimenting with different susbtances!
