On the December 1st, we did a challenge to make a boat and make it move across the basin. The boat needed to hold one marble. The boat also had to move by the wind. I was put into a group of three. We only had 15 minutes to make the boat. We used paper and cut them into pieces and we also used cardboard, tape and a stapler.
The first thing that went well is that it moved really quickly. But really, I think it didn’t really go well. Our group succeeded the challenge but some parts it didn’t go well. Firstly, the sail was tilted because the tape that held the sail wasn’t strong enough to hold the big large sail. Secondly, the boat almost sank because the water got into the cardboard on the bottom of the boat (as you can see from the picture). I found it difficult because there was only 15 minutes to create the boat. It was also hard because it also took time to decide what the design will be. I can improve on to our group’s boat by making the base of the boat bigger so the sail can be stable. We should have use the plastic bag to cover the cardboard. For this activity, I enjoyed looking at other group’s boats because it was really different from our design.
Long time ago at Africa, people from other countries was competing to take over the land. They had a meeting of what country will take how much land at Africa, but they the other country was still fighting. So each country, they sent a explorer to take over the land. Other counties did the same thing too. Countries tried to take over Africa with explores. Over 500 tribes from many other countries tried to take over the land of Africa. Some countries accomplished to take some part of Africa and some didn’t. The country who accomplished to take part of the land used it as mines to find diamonds and emerald. They also found a type of ore called Coltan. This ore helps make phones like I phone, I pad and Mac.
People around the world tried to get the land of Africa because at Africa, there is many resources than other lands and country. People around the world want to get more resources than other countries. So it means that the countries are competing each other.
This happened for many times and finally all the country now decided the space were equal. If you go to google maps and look at Africa, the most borders are straight.
Long time ago, some of the first robots were made. The robot helped people. Some of the robots are a water collector. When the electricity was invented, a robot that looked like a doll helped people writing words, sentences, and even a story.
Now, High-Tech robots do everything. Some robots help car company make cars faster. Unlike the old robots, they are automatically controlled. They are also reprogrammable so they can do many different things. Some robots are at Hospitals. They help the nurse and the doctor for when surgery is needed. Some robots work at your house. A automatic floor cleaner cleans the floor instead of your parents using the mop every week.
These robots were made because it is faster than the humans doing work. It is also easier because it can help other people. It can be also used at school for educating other students around the world.
This invention helped everyone and everything to get faster and easier for the humans around the world from babies to elderly.
Our class was really busy this week ( the last week ). We have been working on our assembly and also the robotics.
For the Assembly, the Central Idea for the Grade 4 was WWA ( who we are ) , People learn different things in various ways. That means people have many ways to learn one thing. For example, 2 students wanted to learn the multiplication. One student learned the multiplication by writing them on a piece of paper. That student is a verbal linguistic learner ( people who learn buy reading and writing ). The other student searched a video for multiplication learners. The student sang a multiplication song out loud. That student is a Musical learner ( A person who learn easily by singing, etc ). These words that describes a person is named “Multiple Intelligences”. Also when making our scripts, we were the first ones to present the assembly. It took me a long time because I had to also perform the French Horn ( instrument ).
Our class has been also working on our Robotics skills. We learned a lot of things like making the robot move, turn, beep the tones, draw/write on the LED screen and other cool coding skills. Next week we our going to have a dance off our robots.
