WE KNOW AND PROTECT CZECH RIVERS E-LEARNING

, WE KNOW AND PROTECT CZECH RIVERS E-LEARNING, We map the world

Ohře, Elbe, Vltava, Lužnice, Otava, but also the river Punkva, as the most mysterious Czech river. Children get to know Czech rivers and interesting things about them in a playful way. They will also learn how to protect rivers. Suitable for children from the first and second three years of Montessori, or for the first stage of primary school. Ideal activity for Map of the Czech Republic.

Dear children,

first listen to a little talk about rivers. You can take a piece of paper and a pencil in your hands and try to write down the names of the rivers you know. Then see how many you managed to guess. We'll talk more tomorrow.

(We draw texts from the Montessori tool called "Discovering Czech rivers", which we offer <a href="https://cdn.shopify.com/s/files/1/1932/8043/files/200721_ODSTOUPENI_BEZ_UDANI_DUVODU__EN.pdf?v=1595428404" data-gt-href-en="https://en.notsofunnyany.com/">here</a>)

Greetings!

I am the hand that caresses the Earth. Sharp stones become rounded by my action. I dig gorges, I pour into valleys and I can be powerful. I am a memory of the landscape and home to many animals I care for. Although I often procrastinate, I never forget my distant goal.

If you throw a stone at my surface, you will see circles as a sign of my constant cycle. Your age-old task is to take care of me and know my names. I invite you, dear man, on a long and adventurous journey together!

Yours river

Dear children,

Your task today is to write down the names of rivers that are located near your home or school. Can you map the path of these rivers from their source to where they end? For clarity, try painting it on paper. And do not forget to mark the names of the tributaries of other attractions.

Below is, for example, the river Bělá. Today the sun shines beautifully on it and it is amazingly clean.

Hi!

Do you know what a river is?

The river is a natural watercourse. Compared to a stream, it usually has a higher flow.

The water in the rivers comes from melting snow, rainfall and water that has soaked into the Earth and springs back to the surface in a place called a spring. 

What two Czech rivers flow directly into the sea? Their names became tangled. WILL YOU COMPLETE THEM?

O - L - D - A - R - B - A - E

 

Can you find these two rivers on the map? (you can print the map and write down the names of the rivers)

Hello children,

today we will make our own washing powder!

Wondering how washing is related to rivers? Lots of! Conventional detergents may contain fasphalts, artificial perfumes, bleaches and cheap chemicals, all of which are substances that do not belong in nature. So let's get into the grating - enumerating what they contain…

formaldehyde - is known not only as a chemical that irritates the mucous membranes, but as a potential carcinogen.

Sodium lauryl sulfate - may release substances dangerous to health.

Until recently, they were added to detergents to soften water phosphates which most wastewater treatment plants cannot cope with. They enter rivers, reservoirs and ponds, causing cyanobacteria to multiply and poisoning fish and other aquatic organisms.

Phosphates in detergents are gradually being replaced zeolites, which can bind to each other from other chemicals present and then release heavy metals (in contact with salts) -in particular, they pollute the sea water in estuaries. With sweat, they get from washed clothes through the skin to our body, where they are able to cause disorders of the immune system.

Bleaching agents and optical color brighteners are added to detergents for the deceptive effect of bright white laundry. Very bleaching substances are very toxic for us and for nature chlorine, which is stored in adipose tissue and increases the overall toxicity of the organism. Chlorine also contaminates water and accumulates in the body of fish.

Task for you: Deliberately look at the washing powders you have at home at home and look for the abbreviations of harmful substances on the label: TAED (tetraacetylethylenediamine, bleach activator), EDTA (ethylenediaminetetraacetic acid), fiber protection stabilizers, ER, KSN, OB, OB-1, Benzenecarbaldehyde / phenylmethanal, DEA, LAS, ethyl acetate, nonylphenol ethoxylate

So these are just a few reasons to buy environmentally friendly washing powders. And what's the best thing about it? You can easily make washing powder at home or in class. It's really simple.

, WE KNOW AND PROTECT CZECH RIVERS E-LEARNING, We map the world

We will need:

Prepare a scale, a container in which you will mix everything and a ladle or a wooden spoon. Next, get:

100 grams of dishwasher salt.

100 grams of core soap (you can find in every store), which we grate on a grater

150 grams of fine soda powder (not crystalline). You can find it, for example, in the Tierea Verde packaging stores, where it will be weighed for you as needed.

150 grams of baking soda.

10-20 drops of essential oil (no need to add).

To wash white laundry, add an additional 100-150 grams of citric acid.

Approach: Grate the core soap on a fine grater. Weigh the other ingredients and mix everything together and store in an airtight jar (such as a large jar).

The powder is used like any other detergent. Depending on the hardness of the water, one to two tablespoons of powder are enough for one washing machine, and a little more for heavily soiled laundry. The powder does not leave a scent on the laundry.

TIP: For washing wool and silk, omit washing soda.

TIP: If the powder starts to clump over time, add a small cloth bag filled with rice to the powder in a container to absorb moisture.

TIP: You can also add vinegar to the washing machine before washing, which softens the laundry and prevents soap from remaining on the fibers.

It's easy, isn't it? So here we go! The rivers will definitely thank you! Next time we will talk about how to make a washing gel…

    Very nice talk about the river. As an idea for an activity. Probably the same would apply to mountains, states, caves, deserts,… The sound form is catchy and reminiscent of reading fairy tales.
