Water on our planet
The water we drink is called freshwater is found as ice at the North and South Poles and in glaciers. The water in the ground and the water in streams, rivers and lakes is also fresh water. There is also salt water. This does indeed taste salty and makes up the majority of water on earth. On average, seawater consists of around 3.5 per cent salt. That's about one and a half heaped tablespoons of salt per litre of seawater.
Water and living organisms
Our planet does not only consist of a lot of water, but also living being. Plants dry out, people and animals die of thirst if they don't get enough water. A person needs between one and four litres of water a day, depending on body weight, heat and activity. If you spent several hours outside as a child and played with your friends all day without drinking anything, you know exactly how much you need to drink.
Generating energy with hydropower
If you've ever stood in a river with a strong current, you know that water has a lot of power. This can be used to generate energy. The faster the water flows, the more power it has.
This means that even large objects such as a turbine can be moved. The rotational energy generated can then be converted into electrical energy. Hydropower plants are also very efficient: around 90 per cent of the energy can be converted into electrical energy. Furthermore, hydropower is a renewable energy source and is climate-friendly and CO2-neutral.
How is water purified?
Your morning tea or coffee, water for personal hygiene or a cool glass of water after sport - none of this would be possible without clean water. That's why we need clean, pure water. But how does rainwater become clean groundwater?
In order to achieve high water quality, the contaminated water must be treated and filtered. Rainwater falls onto the ground, seeps and is filtered on its way through the various layers of rock and sand. On this journey, various particles such as dust remain in the layers, just like in a sieve. The further the water seeps down, the cleaner it becomes. The groundwater purified by the earth can now be used as drinking water.
The "Water purification" experiment set from the TimeTEXresearch workshop is ideal for teaching children in primary schools about this process in an exciting and easy way. This set provides the ideal basis for introducing your pupils to the topic of water treatment and water purification. In exciting experiments, the children playfully learn about two different types of water purification and explore how water can be purified. For example, they build a water filter from different filter layers and familiarise themselves with the individual layers.
Experiments with water for children in primary school
As water is so essential to our lives, our children should carry out experiments with water at primary school to understand its importance. With our "Water" research kit, children will have lots of fun experimenting with water. They are provided with many ready-made experiments on the subject of water that are sure to amaze the students. The set is ideal for kindergarten or primary school.
