The Force

The force

Today for our experiment we found out if the air from the hair dryer could lift a ping pong ball.

You Will Need:

1.A hair dryer.

2. A ping pong ball.

To start off you need to hold the hair dryer as still as you can and slowly place the ping pong ball on top. Then the ping pong ball will go up and the reason it goes up and not to the side is because the force around the hair dryer allows the ball to only go up. But when we put two balls on the hair dryer one of the balls would push the other one off. If one person blows the ball while the hair dryer is on it will not fall off. But if three or more blow on it it would fall off.

Balloon Experiment

                         ~Science~

What happens when air gets hot? Today I will do five paragraphs about our experiment that we did today. The first paragraph will be about what you need,the second one will be about how to immerse in hot water,The third one will be about observation,the fourth one will be about particles and how the heat caused movement,and the last one will be about expanding.

1.You will need half a bucket of cold water and half a bucket of HOT water, two balloons,and  two used plastic bottles. You need to put the balloons on top of the plastic bottles and carefully with tongs you put one bottle in the bucket with hot water on it’s side and the balloon will expand. If you put the other bottle in the cold water It will do nothing and that it called a state of  Inertia.

2.To make this science project you need to immerse the bottle in water. If you don’t know what immerse means it means when you surround something or someone with an object. The steam is rising into the bottle and then it goes into the balloon because it has no where else to go,and it makes the balloon expand. If you leave it in for too long it might pop.

3.On the day we did the experiment we needed to observe the experiment or I wouldn't be able to tell you all this stuff that I’m telling you right now. If you don’t know what observe means it means to sit down and kind of study it or watch it for a long time.

4. The balloon inflated in the hot water because the hot steam raised in the the bottle and the steam had no where else to go so it had to go into the balloon and that's how the balloon inflated. With the cold water one It didn't move and again that is called a state of inertia.

5.The Balloon expanded because the hot air in the bottle had nowhere else to go.So it had to go in the balloon. And that's how the balloon expanded.
