Candles and Oxygen

In addition to any fire turns living creatures need oxygen, 
Through these exciting games or we can prove that the fire needs air.

Materials and tools: 
1. candles, 
2. plates,
3. glasses,
4. matches, 
5. dyes. 

Procedures:
1. First you turn on a candle and place on plate, then take the glass and close the wax using the glass
2. See what happens .. yes ... the candle outages. 
3. To enliven the atmosphere if done in class before the candles on the lid invite students to do hipoitesa with questions.

After the experiment above, we proceed with the following experiment in which we can prove that there really air out when the candle of life.
Still with candles and dishes before, the input of water into the dish, give it a little dye to facilitate observation. Turn on the candle, and then do the same experiment with the above, observe what happens .... and ... .... water is sucked into a glass dish.
Rising water in a glass to prove that that air is lost because it is used in the combustion process so that the empty space is replaced by water.

Naked Egg

Ever see the contents of the egg without breaking?

Through the following experiment where you can see how to view the content without breaking eggs .. how easy ..egg naked let's get started:


Tools and materials:
1. eggs
2. glass
3. citric acid or vinegar


Procedure:
1. Fill glass with water until half full.
2. Add 2 tablespoons of citric acid and stir until dissolved
3. Enter a quail egg into a glass and let some time
4. This experiment can also use the vinegar solution eat


Oooo .. What happened ..Outer skin to peel eggs and turn into white.


Let's find out yes ...


Egg shell is made of a substance called calcium. This substance will change when mixed with citric acid. The result is carbon dioxide gas. That is why you see no bubbles in the glass. Gas is more and more. Because it is lighter than water, gas moves upward, lifting egg.

Change starts from the outermost egg. That is why the skin with brown spots off first. As a result, the egg into the net. If the egg continues to be soaked, then the skin will come off. well now you try to soak the egg task longer what will happen.


Note:
to facilitate a mixture of citric acid can be replaced with regular eating vinegar.

Discovery the Gasses in the Air

Put out the candle without blowing on it or touching it. When you do this experiment, you show that air is a mixture of invisible gases. One of these is especially important. It is oxygen which is used when things burn and produce energy.

Materials:
1. Candle
2. Coloured water
3. Glass jar
4. Bowl and Candle holder

Procedures:
1. Put the candle in the holder and place it in the bowl. Then pour in the water.
2. Ask an adult to light the candle. Then place the jar over it. Leave it for a little while.
3. At first, the water level in the jar rises, and then the flame suddenly goes out!

Air and Energy
Like other cars this racing car gets its energy from petrol burning in its engine. Burning fuel provides most of the energy we use forheating and powering machines. This process uses oxygen, which comes from the air around us.

Weight Some Air

When something is very light, people often say “It’s as light as air”. But air is not light at all. Do this simple experiment to show that air is really quite heavy.

Materials:
1. Balloon pump
2. Two balloons
3. Rubber band
4. Two Drawing Pins
5. Long thin piece of wood
6. Ruler
7. Pencil
8. Sticky tape
9. thread

Procedures:
1. Use the ruler to find the centre of the wood. Then mark it.
2. Push a drawing pin into each side at the centre mark.
3. Tie the thread to the middle of the rubber band.
4. Fix the loops of the rubber band around the drawing pins. Lift the wood by the thread. It should balance.
5. Tape one of the balloon to one end of the wood.
6. Tape the second balloon to the other end of the wood. Check that it still balances. Then remove one balloon and blow it up.
7. Tie the neck of the blown-up balloon and attach it to the wood in the same place as before. The balloon make the wood lose its balance.

Drinking with a straw.
When you drink through a straw, the weight of the air helps you. The air above the drinks pushes on the surface of the liquid. As you suck, it forces the liquid up through the straw to your mouth.

Seal with Air

Stop water falling out of an upturned glass. A card can stick to a glass and keep the water in it, as if by magic! Air pressure forces the card upwards, against the glass. The pressure is strong enough to stop the weight of waterpushing the card away.

Materials:
1. Thin flat card
2. Glass
3. Water

Procedure:
1. Hold the glass over a sink or a basin. Carefully pour some water into the glass.
2. Place the card on the glass. Hold down so the eard touches the rim all the way around.
3. Still holding the card turns the glass upside-down. Let go the card. The water stays in the glass!

Form A Gas

Inflate a balloon without blowing into it, or using a pump! You can do this by making a gas and then getting it to go into a balloon. The gas is called carbon dioxide. It is this gas which forms the bubbles in soda water and fizzy drinks.

Materials:
1. Vinegar
2. Sodium Bicarbonate
3. Balloon4. Funnel
5. Narrow-Necked Bottle

Procedures:
1. Pour some vinegar into the narrow-necked bottle until it is about a quarter full.
2. Using the funnel, fill the balloon with sodium bicarbonate powder.
3. Stretch the neck of the balloon over the neck of the bottle. Do not let the sodium bicarbonate escape from the balloon.
4. Lift the balloon so that the sodium bicarbonate falls into the bottle. The vinegar begins to fizz and the balloon slowly starts to inflate. The vinegar reacts with the sodium bicarbonate to release bubbles of carbon dioxide gas. As more as gas forms, its pressure increases and the balloon expands.

Exploding drink
Shake a bottle of fizzy drink then unscrew the cap. The drink fizzes up out of the bottle! Carbon dioxide gas is dissolved in the water in the drink. It is kept under pressure in the bottle. When you unscrew the cap, you reduce the pressure and the gas bubbles up out of the water.

Crush With Air

Make a plastic bottle collapse without touching it! The air does the job for you. You cannot feel air, but it presses against every surface. This is called “air pressure”.

Materials:
1. Ice
2. Funnel
3. Hot and Cold Water
4. Plastic soft drinks bottle
5. Bowl

Procedure:
1. Stand the bottle upright in a bowl. Pour the hot water into it and leave it for a short time.
2. Screw the top on the bottle. Lay the bottle in the bowl and pour ice and cold water over it. Then stand it up.
3. The bottle collapses! As the warm air inside the bottle cools, it exerts less pressure. The air outside is stronger and crushes the bottle.

A Hat & Chalk

Players sit in circle and the leader begins by passing a ball to the player on their right while saying “this is a cat”. The person will ask, “a what?” and the leader replies “a cat”. The second player the passes the ball to a third player and says “this is a cat” and the third player will reply “a what?” and the question gets passed back to the original leader. Each time the ball goes as far as one more player, and then the question returns to the leader. (everyone has to say “a what?” all the way back to the leader and then “a cat” all the way back to where the ball was before it can be passed on again). Start a hat going the other way for a challenge.

Kuzit

Players stand in a circle. One player is in the middle with a ball. While music is playing the centre person passes the ball back and forth between players. When the music stops the player who last touched the all must run around the circle and get back to their spot before the person in the centre can name all the colours the runner is wearing. If they name all the colours they then switch places with that player. An alternative instead of playing music is to get the group to sing a song together.

Clothesline

players are formed into teams of equal numbers. Each person at the front of the line is given a roll of cord with a spoon attached to the end. At a signal, the front person takes the spoon and puts it down their top and pants, the next person takes the spoon and cord and puts it up their pants and top. This goes on, until the whole team is connected. Hey collectively move to a line 50 feet and reverse the sequence to get the spoon back to the roll.

Bed Sheet Ping Pong

Form two teams. Each team holds an opposite end of a bed sheet. A ping pong ball is placed in the middle of the sheet. The object is to get the ball to fall off of the other teams side, for a point. The sheet can be raised and lowered as needed but remind the players to be careful not to “launch” the ball as they will be very

Back Words

Divide the group into teams of 5 people each with pencil and paper. Call out a word which has four or more letters. Each team writes the word vertically down the left side of the paper, and on the right side write the word vertically backwards. Then they have to fill in between the letters to form new words.

Hungry Animals

Players are divided into different animal groups. Each group has a “collector”. In the playing area there are “treasures” (i.e. Bean bags, candies) which animals try to find. Once treasure is found, the animal makes their

Cone guard

Toe teams compete by passing a ball between team members to the opposite end of the playing area. When a team member drops a pass or it is batted away, the other team takes over that spot. The object is to hit the other team’s pylon with the ball. Players cannot encroach on a three foot diameter goal area which a goalie stands in. If the goalie touches their pylon the other team is given a point.

Confusion

Players stand in a circle and face each other with hands raised waist high. A ball is thrown to one person who in turn throws it to another and so on to establish as pattern. Once you’ve caught the ball, put your hands down until everyone has caught the ball. The key point is to remember the person you threw the ball to. When the ball gets back to the person who originally started it, the same sequence is repeated. To add excitement put in a couple more balls and speed things up. Try doing it backwards too.

Clap It

All players sit in a circle except for one player who stands out of hearing and faces away from the group. Quietly the group picks out something someone is wearing and the first player returns to the group. As they walk around the circle the player’s clap, louder when he is near and quietly when they are far away. Once the right person is located, the object must be found the same way as they more their hands about the person’s body looking (listening) for the object.

Belt Loop Ball

Divide the players into teams of 10 people. Each team competes with itself to ‘play’ the game successfully. It is fun to have different players make up each team every time the game is repeated. Each team stands in a straight line; they are tied together by passing the rope through the left loop of every player’s belt. The object of the game is to guide a soccer ball (players use only their feet) from one side of the playing area to another. However, the only players who are allowed to kick the ball are those holding one of the two ping-pong balls. Every time the leader calls “SWITCH” the people holding the ping-pong balls pass them on to different members of their team. Only one kick per time holding the ping-pong ball is permitted. After each team becomes adept at completing the run across the playing area, competitions between teams can be organized.

Hop Along

Players stand in pairs face to face. They then lift their right leg straight up and allow their partner to grab it under their left arm. In t his position they must hop to a designated spot and then run back to allow the next pair to go. This game may be done in threes or fours and also it can be done as a relay race.

Circle of Stone

Players sit in a circle with one in the middle. A second player steps in and the two sit face to face. Without touching them, the second player has six seconds to make the first laugh. If successful, the second player becomes the stone and a new challenger steps forward.

Battle For Freedom

The majority of players crouch on the floor pretending to hide an object which only one player actually has. Five “Freedom Fighters” run from player to player asking, “have you got the Rhune?” as soon as they locate the Rhune, they attempt to hit the two Warlock Lords, (use a foam ball) who in turn have been trying to hit the freedom fighters from the start of the game. Once a player is hit they are immobilized.
