Stop-motion

There is a type of video called stop-motion; stop motion is a ton of photos played fast and that forms a video. I tried out an app called stop motion studio. Stop motion studio is an easy cheap app that you can use to take pictures on, and once you are finished you can play the photos together as a video, you can also adjust the speed of the film. and you can add sound effects, green screen backgrounds, titles, and more. I had purchased the pro version of the stop motion studio because if you don't the app will only allow you to use the camera and the photo playback. I love that I can use the greenscreen because it sometimes helps when I don't have a good background. Here is a film with legos that I did earlier: 

 

Spread and Adoption of the Wheelbarrows - History of Inventions - Lesson 31

The most common type of wheelbarrow used today by China is a type of wheelbarrow where the wheel is in the middle of the wheelbarrow. Here is a picture of that: 

The center wheel design is also used for carrying people around on it, and it could hold up to six people on it! Some of the Chinese wheelbarrows had sails on them for easier pushing/pulling if it was a big load and if they were going a long way, here is a picture of that: 

The Europeans had probably come up with the idea of the wheelbarrow by themselves because there is no trace of the Europeans getting the invention of the wheelbarrow from China. I find interesting that China had used sails on their wheelbarrows for helping them to push or pull it around.

iPhone 11

About a week ago, an iPhone 11 arrived in the mail. It had was bought by my uncle. It is for my grandpa and grandma who is going to move back to Lake California. Once it came in, I logged into my Grandpa's Apple ID, and then I had started setting up the iPhone. The iPhone 11 does not have an actual home button like most other types of iPhones, but instead, you just swipe up on the screen and does the same thing as a home button, if you don't know what a home button is, it is the button on the bottom of the iPhone (shown in the image below)

The reason why it does not have a home button is that the screen fills up the whole front of the iPhone 11. The iPhone 11 also has some other perks, most of the different iPhone versions don't have. But I am still figuring those out. 

Wheelbarrow - History of Inventions - Lesson 31

A wheelbarrow is a tool used for agriculture, and construction, it is meant for moving sand bricks weeds, etc. It benefited the workers because you wouldn't have to use a horse to pull a carriage to transport materials if it is a short distance. After all, it would take to long to hitch up a horse to a wagon for just a small range. It was also useful because it was small enough for going in tight spaces rather than a truck that could only move around in bigger areas, and the wheelbarrow helped with the health because it prevented backs from being broken. A Chinese man named Zhuge Liang (181 AD - 234 AD) was the first to invent the wheelbarrow, he had invented it for moving war supplies around quickly when he was in war with a rival clan who were fighting for the throne. It was used a couple of times for people who could not walk basically as a wheelchair.

Sailing Before the Compass - History of Inventions - lesson 29

Before the compass, many people had to rely on landmarks for sailing. The Polynesians sailed around there own area by using the stars to tell them where they were, and they also used waves to tell where land is because the waves get affected by the islands. The Europeans used landmarks, the stars, and the familiar winds that blew by them as they were sailing. It was almost impossible for most people to sail in the winter because it was always cloudy and you couldn't use the stars to tell you where you were. In that case, you could end up in entirely different countries. I think it is pretty interesting how the Polynesians used the waves to tell them how near they were to land.
