Experiment

MATERIALS: 1. Regular orange 2. Peeled orange 3. Deep bowl or pitcher of water One of these oranges will sink and one will float. Drop each orange into the water separately. While the orange with the peel is certainly heavier, it will float while the peeled orange sinks. This is because the orange rind retains air. The air bubbles give the orange a lower density than the surrounding water, causing it to float.

”Ghost balloon in the bottle” Prepare: 1. Empty bottle 2. Balloon 3. Straw Execution: 1. Put the balloon into the bottle and try to inflate it (it will not work) 2. Now put a straw in the bottle next to the balloon and try to inflate it again. What will happen? It will manage to inflate the balloon .... Why? There is also some air in the open, seemingly empty bottle. When you try to inflate the balloon, it will completely close the opening of the neck of the bottle and the air contained in the bottle will not be able to get out. For this reason, you will not be able to inflate the balloon. Only when you let the air escape from the bottle through the straw, you can inflate the balloon and fill the surface depending on the shape of the bottle.

LETâ&amp;#x20AC;&amp;#x2122;S EXPERIENCE AND LEARN EXPERIMENT NEW COLOURS Materials: plastic dishes, paint brushes aand different colours of finger painting or temperas. We mixed two colours of finger painting in a plastic dish and we stir them in order to find a new colour: Yellow + blue = green. Yellow + red = orange. Blue + red = violet.

LET’S EXPERIENCE AND LEARN The Newton disc is a well-known physics experiment with a rotating disc with segments in different colors (usually Newton&#39;s primary colors: red, orange, yellow, green, blue, indigo, and violet) appearing as white (or off-white or gray) when it spins very fast. We tried to spin disc with coloured rainbow in stripes and dots drowen in a spiral. We saw a rainbow stripes. When we spined disc splited in to the triangles: in turns blue and yellow, we saw green colour, in turns red and yellow, we saw orange colour. At least we tried „right“ Newton disc with six colours: yellow, red, violet, blue, light blue adn green. We had to see white disc, but we saw light grey. It is probably becouse we didin´t use orange colour in our disc. In film you will see probably disc with all colours,i tis becouse human eye isn´t perfect and it doesn´t see, what lens of camera can see.

Mix the top layer of water so that it rotates very quickly. 3. Add a few drops of dye or ink to the center of the vortex. What will happen? The swirl funnel will appear Why? The air in the tornado moves in the same way as the dyed aquatic swirl hopper. The tornado&#39;s whirlwind starts high in the air. It consists of winds spiraling down.

LETâ&amp;#x20AC;&amp;#x2122;S EXPERIENCE AND LEARN We put plain baking soda inside our volcano. In a second bowl, we combined the vinegar, dish soap and food coloring. The baking soda reacts with the vinegar to produce a gas: carbon dioxide. The gas builds up enough pressure to force the liquid out of the top of the bottle. The bubbles from the soap help carry the mixture down over the sides of the volcano.

LETâ&amp;#x20AC;&amp;#x2122;S EXPERIENCE AND LEARN EXPERIMENT THE STATIC ELECTRICTY MATERIALS *Balloon *Paper Butterfly

WORK PLAN -Blow up a balloon and rub it in your hair to give it electricity charge. Now hold the balloon on top of your butterfly close enough and watch the wings raise and lower as you move the balloon closer and farther away.

-Our hair looses electrons that are gained by the balloon giving it a static charge. When negatively charged balloon gets close to the positively charged tissue paper they are attracted to each other, and so tissue paper moves towards the balloon.

LET’S EXPERIENCE AND LEARN Myszków/Poland

”Deformation through ice” Products needed: - crushed ice - a plastic bottle with a screw cap How to prepare: 1. Put crumbled ice into a bottle and turn it off. 2. Shake the bottle well so that the walls cool down. Put the bottle horizontally on the table. What will happen? The bottle will shrink and deform. Why? The ice cools the air in the bottle and therefore the bottle shrinks and reduces its volume. The air from the outside presses against the walls of the bottle and deforms it.

Experiment How plants absorb water (and nutrients) up through their stems.

MATERIALS: 1. Chinese cabbage 2. Water 3. Food coloring 4. Clear glass jars, cups or small clear vase Fill the glass with water. Into each glass a few drops of food color. Then place a separate cabbage leaf in each glass. Children do the observation and assume what happens to the cabbage leaf because it lives in color water. As the leaves of cabbage drink the water they will magically change color.

LETâ&amp;#x20AC;&amp;#x2122;S EXPERIENCE AND LEARN EXPERIMENT MIXING THE COLORS MATERIALS *Water *Glass *Paper

WORK PLAN -The three primary colors are red, yellow, and blue; they are the only colors that cannot be made by mixing two other colors. The three secondary colors are green, orange, and purple; they are each a mixture of two primary colors. Their hue is halfway between the two primary colors that were used to mix them. -We put papers into the glass. Later we add some water into the glass. -and we sight. red + yellow = orange blue + yellow =green red + blue =purple

Winter Experiment „ICE HANDS“

MATERIALS: 1. Latex gloves 2. Water 3. Food coloring 4.Twine 5.Shallow baking pan - Fill a glove with water. - Leave yourself a couple of inches at the top because you’re going to have to twist it shut. - Add a drop or two of food colouring, and shake the glove to disperse the colour. - Gloves tightly and firmly fastened with twine - If outside temps are cold enough, place the gloves outside or place the pan with the gloves in freezer overnight The trick to minimizing any casualties is to run the gloved hand under a bit of water, and very gently slide the glove off. You have to take your time when you’re working on the fingers. You may have to dribble a little water into the glove, but be careful not to melt the fingers with the water.

LET’S EXPERIENCE AND LEARN EXPERIMENT 5 A Baloon rocket 1 balloon (round ones will work, but the longer “airship” balloons work best) 1 long piece of kite string 1 plastic straw, tape

What to do Tie one end of the string to a chair, door knob, or other support. Put the other end of the string through the straw. Pull the string tight and tie it to another support in the room. Blow up the balloon (but don’t tie it.) Pinch the end of the balloon and tape the balloon to the straw as shown above. You’re ready for launch.

Let go and watch the rocket fly!

LET’S EXPERIENCE AND LEARN For this experiment we used a juice from red cabbage. We made it by pouring hot water to red cabbage pieces and next we strained it. Clear juice had a violet colour. Next we poured cabbage juice to weater with vinegar. It coloured on the light red. We poured „juice“ to coca cola. It changed colour for dark red.Next we poured to water with soap,witch coloured on the light blue. We poured our „juice“ to milk, it coloured on blue too. The last one was a tee, which we drink every day at kindergarten. It changed on a light red. Red cabbage contains a water-soluble pigment called flavin which is an anthocyanin. Anthocynins can also be found in apple skins, grapes, poppies and plums; and it changes colour with the pH (or acidity/basicity) of the solution it is in. Very acidic solutions turn it a deep red; neutral solutions make it a purple-ish shade; and basic solutions turn it a greenishyellow. So now we know, thta vinegar and coca-cola is acid. Basic is soap and milk.
