Experiment for future astronauts.

MATERIALS:

• balloon

PROCESS:
Blow up the balloon and tie it.
Rub it against your hair on top of your head.
Watch what happens! Your hair will stick up!

Static electricity.

When you rub the balloon on your hair, you’re covering it with little negative charges. Now that each of the hairs has the same charge, they want to repel each other. In other words, the hairs try to get as far away from each other as possible. The farthest they can get is by standing up and away from each other.

Experiments.

Coffee, oil, water and salt.

You need water in a glass, then add some oil, then add coffee at the top. Oil is lighter than water, coffee is lighter then oil. Put some salt on the coffee and wait for a while.

Salt is  heavier so makes coffee sink. But after a while salt dissolves in water and lets coffee come to the surface.

Materials:

• Shallow bowl 
• Water
• Pepper
• Dish soap
• Toothpick or a finger 
• Paper
• Pencil

Procedure

1. Fill the bowl with water.
2. Sprinkle pepper evenly across the surface. 
3. Squeeze a tiny bubble of dish soap onto a clean counter.
4. Touch the tip of your  finger to the bubble of dish soap. 
5. What do you think will happen when you touch your soapy toothpick to the water? How will the pepper flakes react?

As the soap moves into the water, and the surface tension changes, the pepper no longer floats on top. But the water molecules still want to keep the surface tension going, so they pull back away from the soap, and carry the pepper along with them.

Experiment: How does the food taste in Universe?

The crew from Brasov experimented the life in space after watching some videos and reading some articles about the issue.

THE MOVEMENTS OF EARTH AND MOON, CYPRUS

This week we learnt about the moovents of the moon around earth and the moovents of earth around sun. we learnt about days and nights!

Experiment 2 - Poland.

Material List:

1. two balloon
2. two narrow necked glass bottles
3. a pan of hot water
4. a pan of ice water

Procedure:

Take the balloons and stretch it gently over the lip of the  bottles. Place the bottle into the pan of hot water and let it stand for a few minutes. To reverse the outcome, place the bottle into the pan of ice water and let it stand for a few minutes.Observe.

This activity demonstrates that the air inside the  bottle expands when heated causing the air molecules to move faster and get farther apart. This is what causes the balloon to inflate. Warm air is less dense than cold. Since warm air takes up more space than the same amount of cold air it makes the balloon inflate.

Experiment 1 Romania

Wind is occur when the air is moving.

We used a burning candle and we moved it next to an open door, 

What does happen? 

The flame is moving in the direction of the wind: into the room, when the candle is up and out of the room, when the candle is down. That means that the air is moving and the warm air is up and the cold air is down. If we open a door, the air is moving quick and the candle is burnt up. 

Experiment 1.

Small Portuguese scientists!

The first experiment.

A candle is placed in a shallow dish with water and is lit. A glass is put over the candle.

After the candle extinguishes the glass fills with water.

Why does this happen?

Whilst the candle is burning, the air inside the glass heats up. After the candle extinguishes, the heat is taken away and the air cools quickly. This results in a vacuum/negative pressure which balances out as the water enters the glass.
