Science lunar vs solar eclipse

I noticed that each phase of the moon is different. Some are half full, full, 1/4 full, 3/4 full and other.
We see different parts of the moon each night because the moon is moving around but earth is moving the other way.

I cant answer this question because I never did a moon model

Maybe making a 3-d ball and coloring the parts of the moon in black representing the dark side of the moon

A lunar moth is a month measured between successive new moons (roughly 29¹/₂ days).

Radical planes take shape

As we go one step to the future, we see amazing things. Right now we will see future planes. Scientists have already created the future planes! They have reduced the pollution, noise and  fuel of each new plane. Now some of these planes are not exactly for how they say traveling. Some of the planes are very flat just like the ones in the U.S army.
Here are some pictures of them:






All of these planes are not fake. It was said that these planes are not fake by the U.S army and also Nasa. Many of these planes are extremly fast that they travel almost 300 mph per hour! Scientists say that these planes are not yet ready to be released to the world because they have not fully tested them yet. But when I look at them, they seem funny and not quit safe. Like that plane in the last image and the second last plane.

Tsunamis

Tsunamis

Tsunamis are the most dangerous natural disasters. They destroy anything in their way and also carry float-able objects with it. There are many tsunamis happening every year and they come in different sizes. Every single tsunami kills hundreds of lives and scientists are still trying to figure out on how to save people. Tsunamis knock down houses and the people that survive become homeless. But what are Tsunamis? Just as I said in the beginning, tsunamis are a part of natural disaster. They are a huge chunk of wave that gets bigger when they move forward. Then they fall down when they are close to land and send water charging at the people and buildings. How are Tsunamis caused? Tsunamis are usually caused by earthquakes that happen at the bottom of the sea floor (people call it the seabed) or they are caused by very strong winds. The way tsunamis are caused by earthquakes is that the seabed floor cracks and the floor moves up very fast that the waves go up as well and start to get bigger. The effects that are on people and animals are that they will drown if they stay in the tsunami too long or they will die if they hit something hard when they are inside the tsunami. The best thing to do when a tsunami is coming your way is that you should quickly get inside your house so that the tsunami wouldn’t carry you. Also the buildings and houses have effects too. When a strong tsunami hits in, the tsunami can knock the buildings and houses down that they will also fall on people. The approximate estimate of how many people die in a year is between 25,000 to 150,000. Scientists have created this new technology called the tsunami generator. It has been engineered and developed by the Engineering and Physical Sciences Research Council. Or people call it the EPSRC in short. This generator creates waves and also mini tsunamis. This only works when you add water to the generator. You may ask yourselves why this is helpful. This is helpful because this helps the scientists to study the waves on how they behave, how and when do they form and how powerful is a tsunami. In the future, scientists will make something like a barrier or anything else that will save lives for all the people. In conclusion on how to stay safe, here are some tsunami survival tips: number 1, when you are in any coastal areas always be alert for tsunami warnings. Number 2, Plan an evacuation rout that will take you to safety. Number 3, Know the warning signs when a tsunami is about to hit in: rapidly rising waters and rumbles in the sea.  Number 3,  Never stay close to the shore when a tsunami is coming. Number 4, be sure you take some survival supplies if you are in danger. Finally number 5 ,  never return to a affected coastal area unless authorities say it is safe. So that's all. The worst thing is when you live next to the beach.

Create your lab: Waves

Science

What happens when you drop a small and light object into the water? What happens when you drop a big and heavy object into the water? What kind of waves will these objects make?
What I am sure of is that light and small objects make small waves that quickly disappear. Bigger and heavier objects make bigger waves that last longer. Because The bigger the object, the bigger the wave and the bigger the wave, the longer it lasts.

What you need for this:
1. plastic pan
2. water
3. heavy and light objects
4. ruler
5. timer

Fill up the plastic pan of water. Next find some light and heavy objects in your house. Drop either the light or heavy object into the water. Pay attention on what waves does the object make. time how long the wave lasts and measure the height quickly.

Here are my observations:
small rock: height 0.1 mm, time: 2 seconds
dragon statue: height 0.5 mm, time: 4 seconds

When I dropped the small rock into the water, it made a small splash. it lasted for only 2 seconds and its height was 0.1 mm. The dragon statue made a big difference. it made a big splash and the wave lasted for 4 seconds and its height was 0.5 mm.

I saw that the relationship was that how did the small rock and dragon statue react when they hit the water. They both made different waves because the small rock is small and the dragon statue is big.

So in conclusion, Objects with different kind of weight and different size make the wave either big or small.
I did have some errors while doing this. When I was dropping the objects into the water, they made the splashes too quickly and I couldn't get the height. Next time I should use a different strategy of how to measure the height of a wave.
I also have one final question. What happens when you drop the small and light object and the big and heavy object at the same time? Would they make the wave bigger or would it just be the same? 

Meteor kills hundreds in central Russia

Around 9:20 am, People have seen a bright light that blinded everyone. When the light was gone, There was a meteor! it was headed straight to central Russia. It was enormous and exactly the size when you are looking at the sun. But the confusing part was when the meteor was falling, all of a sudden the meteor disappeared. The meteor has killed about 950 people and 46 of them are right now in the hospital. But not only did the meteor killed the adults, it also killed about 204 kids! The meteor also hit a part of Kazakhstan and also Moscow. Scientists predict that the meteor was going 1,500 km per hour and traveled about 930 miles. But nobody cannot figure out how did the meteor got so small all of a sudden. But there is prove. The meteor was going at the speed of 1,500 per hour and it went so fast that it got on fire and soon it vaporized, The explosion created giant shock waves and waves that destroyed all the buildings in its wave and send people flying. Mr. Putin the doctor promised that all the injured people that survived the meteor crash but got hurt will get medical treatment. But he is going to need a lot of doctors to do that or else the people will die. A lot of houses were lost and destroyed and nobody knows how long it will take to build new ones. Also nobody knows where the people will live (that is if they survived) In the link below shows the video of the meteor. It is pretty cool!

Making waves

The Wave Project

Last week on Friday we did a wave project. That means we were testing on how waves react to solid objects and floating objects. The guiding questions are:

1.     When water is dropped from a pipette into a pan of water, how does the wave behave?

2.     What properties does a mechanical wave have?

3.     How do waves interact with each other and with solid objects in their path?

 

My answers to these questions

1.     First, the drop from the pipette makes a quick splash, then it creates small waves that begin to grow when they expand and disappear or continue when they hit objects. But they bounce off only when they hit something plastic.

2.      A mechanical wave is a wave that requires a medium through in which to travel.

3.     Depends, when 2 waves interact with each other, they make a splash and stop. When they hit a non still object, they carry it along. But when waves hit a still object, 2 things can happen: 1. The wave will pass the still object and go around it, 2. If the wave has enough power, it can knock the still object down and maybe carry it along.

My hypothesis is that waves can be stopped by strong objects but not moving ones.

 

Do you wish to try this too? Great! Here is the list of steps for this experiment:

1.     Water

2.     Modeling clay (2 bars)

3.     Ripple tank (plastic or metal)

4.     2 plastic droppers

5.     Paper towels

6.     Cork ( or small Styrofoam ball)

 

Safety: When doing this experiment, be sure to keep away from any electronics or move them so you or nobody gets hurt thank you.

Here are the directions:

1.     Fill the pan with water

2.     Fill the plastic droppers and then release drops 10cm high. You can do this in the middle, in corners, at the ends or anywhere.

3.     You can also try to do this with 2 droppers. You know what they say: Double the item, double the fun!

4.     After you do this, place a cork, 2 sticks of clay or a Styrofoam ball into the pan. Then fill the droppers with water and see how the waves react to the objects.

5.     Final step: gently place the paper towel on top of the water so it could float. Then fill the droppers with water and see if the towel sinks or floats.

 

These are my observations when I was working with my partner:

 

When I was dropping water into the pan, the drops made tiny waves and bounced off of the walls. But when I and my partner did this with 2 drops at the same time, the waves crushed into each other and turned direction. With the cork it was different. When I was dropping water, the waves hit the cork and disappeared but the cork moved a little. This happed every time when I dropped water somewhere else. When I used the towel it was fun. The towel was floating on the water and when I dropped water, the towel didn’t even sink! The best part was when I used the clay. The clay sticks made good defense barriers and blocked the small waves.

 

So in conclusion, waves can be stopped by still objects or when waves hit each other.

My hypothesis was correct and it truly is because barricades can stop giant or small waves.

 

And here are 2 pictures that you can follow too if you didn’t understand the rules. The second one is just how I was supposed to do this:

strange mutated sea animal

The nuclear explosion that happened in Japan and spread across the world happened a long time ago. Many animals got born differently, humans got born differently and almost everything got born differently because of the nuclear explosion. But one day some scuba divers while they were exploring the depths of the oceans found a blue creature that was also mutated when the nuclear explosion spread. It was a sea animal with blue skin, four legs and four tentacles on each leg (or mabye even more). Also the creature had some marks on its back and had two small eyes and one big shaped like a nose in the middle. When the scuba divers brought it to the shore, the creature just froze for a while. Then it slowly moved its head around to see where it is. Then the creature looked at one of the scuba divers and made a slow blink. The scuba divers took a picture of it and it looks like this:


Strange isnt it? People say it is a sea slug but it isnt. Nobody knows what this thing is but it creeps people out, just like the first picture on the left. It is indeed a beautiful creature and I like it too. Can you guess what this mutated creature is that got caught in the nuclear explosion?
