Science Fair

I just had my eighth grade science fair at my school, and my experiment was quite interesting.

My partner, Jenny, and I observed the differences between the reactions of two kinds of bar soap when microwaved for a certain time. The two bar soaps we microwaved were Dial, and Ivory.

First, we microwaved each soap for one minute, and the second time for two minutes.  The Ivory soap puffed up like Souffle, and the Dial soap flattened like a pancake.

Why did this happen? When Ivory soap is being made in the factory, air is pumped into it, resulting in several air bubbles inside the soap. When the soap is microwaved, the air molecules gain more Kinetic energy, and move faster and farther apart from each other, causing the soap to expand. This demonstrates Charles’ Law, which states “As the temperature of a gas increases, so does its volume.”

The Dial soap, on the other hand, does not contain as many air bubbles. Therefore, it just melted and flattened onto the plate.

Day 7: World Records

Hi everyone!

It is day 7 of the post a day challenge.

For this post, i’m going to list a few interesting world records.

Largest flower: Rafflesia, 80 cm in diameter.

Largest rabbit: Ralph, a rabbit which weighs just under 55 pounds.

Largest horse: Big Jake, a Belgian Gelding. He weighs 2600 pounds, and stands at 82.75 inches.

Fastest aircraft: Space shuttle. It’s top speed is 28,292 km/h, or 17580 mph.

Cool, right?

Thank you,

Day 3: Bird Flu Outbreak

Hello everyone.

It is day 3 of the post a day challenge.

In this post I will talk about Bird Flu, and the outbreak in China.

What is the bird flu? The bird flu is a viral infection directly transmitted from chickens to humans. Transmission of bird flu between humans has not yet been confirmed. If there is an outbreak of bird flu, humans can get infected by contact with infected chickens. People could also catch bird flu by consuming  eggs or poultry which are not fully cooked, or touching someone who has the bird flu.

The most recent outbreak of bird flu was in China. Earlier this year, several people were infected by bird flu. The H7N9 bird flu outbreak started in March, and has infected 130 people, and killed 37. The overall death rate during the outbreak was estimated to be 36%.

After closing the majority of live animal markets in China, the outbreak came to an end. Now it is assumed that the bird flu virus had been infecting people by contact with birds.

Day 2: Cloud Bursts

Hi everyone!

This is day two of the post a day challenge! Not running low on ideas just yet!

Today I am going to talk about something other than photography or animals. The topic of this post is cloud bursts.

For those who are not aware of what a cloud burst is, let me explain. A cloud burst is a severe amount of precipitation, which is sometimes combined with hail and thunder. Cloud bursts usually last only a few minutes, but can cause dangerous flash floods, killing, hundreds of people.

Analogy: Think of a cloud burst in analogy to someone dumping water out of a bucket onto a swarm of ants. What happens to the ants? They are swept away. That’s what happens to the people under a cloud burst.

Cloud bursts cover only a few kilometers, but can flood the whole area. The rain fall rate during a cloud burst is usually 100 mm per hour or more.

Cloud bursts occur around tropical thunderstorms. In tropical storms, there is more moisture. Another factor is the freezing level. Tropical storms typically have a higher freezing level . The water droplets cannot be frozen into hail stones, so they increase in size as water droplets, not hail stones. I the thunderstorm becomes weak, all the water will break through the storm all at once towards the surface of the cloud.

This is the point of which the thunderstorm falls apart. When the water reaches the surface of the cloud, a cloud burst is formed, and the thunderstorm is destroyed.

Personally, I think this is pretty interesting. I decided to make a post on this topic when I heard about a cloud burst which happened in Uttarakhand, a state in India.

Thanks you,
