There’s chemistry everywhere, all the time. We’re made from chemical compounds and everything that happens in our bodies, even our thoughts, is a chemical process. The Chemistry Lab is where we explore the magic of chemistry.
The Chemistry Lab has a minimum admission age of 3. Children aged 3–9 are welcome if accompanied by an adult.
It is called a chemical reaction when chemical substances form new chemical substances. Some reactions start on their own while others need an addition of energy, such as heat, to get started. Reactions can be fast and powerful as in New Year's rockets or slow as rusting iron.
A real Chemistry Lab!
In The Chemistry Lab you do experiments under the guidance of an explainer. In the program and on the screen outside the lab, you can see what times the labs start.
The Chemistry Lab got room for 32 persons at the same time. Bag your place by taking a ticket from the board outside the lab. The tickets are released 15 minutes before the lab starts.
Here are some of the labs we usually do:
Welcome to a colorful chemistry lab! Put on your lab coat and experiment with fantastic colors.
What gives the planet Mars its red color? What is on the poles of Mars? And in what ways are Earth and Mars different? In the Chemistry Lab, we explore some of the challenges of settling on Mars through colorful and smoky experiments.
Write secret love messages that only chemistry can reveal – then give them to someone you like. We also explore how UV light shows things in our environment that are hidden from our human eyes.
Acids and alkalis
Substances can be acidic, neutral or alkaline. Acidity is measured on a scale called pH. In the middle of the scale we find neutral substances, like tap water. It has a pH of 7. At home in the kitchen you can find lots of examples of acidic and alkaline substances. Lemon, yoghurt and vinegar are acidic and all have a pH below 7.
What determines whether a substance is an acid or an alkali is the amount of positive hydrogen ions, protons, in the solution. The more hydrogen ions, the lower the pH. Positive hydrogen ions are very important for all living things. This is why the natural world is very sensitive to changes in pH.
The amount of carbon dioxide in the atmosphere is increasing. When carbon dioxide is dissolved in sea water, it forms carbonic acid, which results in the pH falling and the sea becoming more acidic. Many ocean organisms such as coralline algae, sea snails and crabs have shells made from calcium carbonate. When calcium carbonate comes into contact with more acidic surroundings, it becomes porous and finally dissolves. This is a problem if you happen to be made from it.
You can test how an acidic environment affects something made from calcium carbonate. Put a raw egg in its shell in vinegar overnight. What happens?
