Year 5

Hi we are Kama, Darren, and Max from 5B. Today, we are going to talk about our drama musical production.

The drama musical production is about panji tales.

Every Thursday for these past weeks in art and music lessons we have been practicing for our drama production. We also made our own lines. In the first week, we practiced acting and singing. After a week the main actors in the first scene practiced singing in the music class. After we finished practicing the first scene, we moved on to the 2nd scene and after they finished they also practiced singing. After we finished practicing all the scenes, we all got roles for finding background pictures, background music, props and the backdrop.

Ibu Primi and Ibu Nadya taught us how to perform and sing better. Ibu Primi told us that we need to look at the crowd while performing and Ibu Nadya told us how to sing while doing movements like it's a musical.

Everyone participated and worked hard.

5B’s Math Investigation

Angles

What are the types of angles?

There are 3 essential angles, The right angle which must be 90 degrees exactly, the acute angle which can be anything under 90 degrees, and the obtuse angle which can be anything over 90 degrees. There is also one more angle which is the straight angle and it must be exactly 180 degrees.

What have we learned this week about angles?

This week, year 5B has learned how to create angles using protractors.

To create an angle, you have to write a dot/point anywhere around your paper and line it up with your protractor. After that, write down another dot/point based on which degree you want to make the angle. For example, you want to make an acute angle and you want to make it 60 degrees. After lining up the protractor with the point/dot, you find the number 60/60 degrees on the protractor and write another dot on the spot. Then connect them to make an acute angle. There, you’ve made an angle!

Converting measurements

During these 2 weeks, we learned about how to convert measurements like km to m or mm to m. If we use the staircase of measurements, to convert down, you have to multiply. To convert up you have to divide.

How does this work?

So if we want to go from km to him you have to multiply by 10. If we go from km to the dam we have to multiply by 100, then the farther you will convert it will add 10. So from 10, 100, 1000, 10000, 100000, 1000000, etc. 1 step = 10, 2 steps = 100. Just add a 0 every 1 step you go.

Converting

So if we want to convert down from 1 km to m, you must know that 1 km = 1,000 m. Next, you will multiply by 1000. So, the equation is 5 km = ???? m.

So you will do this below,

1000 (staircase) x 5 (km) = 5000 (m)

So the answer is,

5 km = 5000 m.

Circles

What are circles and how do you measure them?

One of those questions is easy to answer.

What are circles? This week we learned about circles and we learned that a circle is a shape that can still be folded in half from any angle and still be the same and can have as many fractions as you like.

Now, the more complicated question: how do you measure a circle? To do that you need Pi. Pi is when you divide the circumference (that means half of a circle) by the diameter (meaning that it is half of the half), and the answer is always Pi or 3.14……. It goes on forever.

A pi is an irrational number, meaning that it can’t be written as a fraction.

22/7 has an answer that is similar but not the same as pi.

The circumference of a circle is C = 2 X Pi(3.14) X R

The R stands for the radius of a circle, it’s kinda like the 4th fraction of a circle.

You can get the area of a circle by plugging its radius into the equation

A = Pi(3.14) x R2

Pi = 3.1415926535……….

Lines

What are lines, what are types of lines, etc.

We started to learn about lines on September 15, 2022.

There are 8 types of lines that we learned and it is a horizontal line, vertical, straight, curved, parallel, perpendicular, ray, intersecting line, line, and line segment.

What are the types of lines?

Lines are when there are two points but both never end. Line segments are lines that have an ending and a start. A ray is a line that has a starting point but never ends. Parallel lines are two lines that never intersect like an equal sign. A horizontal line is a straight line that goes from left to right or right to left. A curved line is a type of straight line with a bent.

It was challenging to understand in some parts during math, but after practicing we understood and we were able to solve all the problems and tasks.

Year 5 UOI 2 Project - Simple Machines and Scientific cxForces

The Introduction

We are Nathan, Anka, Katherine, Eden, and Daniya from year 5B. Today we will talk about the year 5 project and what we have done so far. We will also share what we have learned about while doing this project.

What is the aim?

In this project, we had to create and design a working machine. The main idea is to create a project about connecting simple machines to make complex machines.

What are we doing?

In this project, we tried to find a problem in our daily life. Then, we brainstormed and found a complex machine as the solution to that problem. After that, we used the scientific method to organize our information. We also designed a 3D model. Then, we created an actual model. After that, we shared what we did to other people.

The IB learner Profiles We Used

We were thinkers because we had to think about what we are going to do and the materials we needed
We were knowledgeable because we did research and took notes
We were communicators because we had to ask each other when we had to use the hot glue gun and the box cutter
We were risk-takers because we had to do it ourselves
We were principled because we had to be careful with some dangerous things we had to use

What is this Unit about?

In this unit, we learned about simple machines and how they worked together to make complex machines. We did a project about complex machines, and we had our separate work. For example, some people did a project about pulleys, wheels, axles, and inclined planes. We made projects about simple machines and how they can become complex machines. We are going to have an expo about our projects and we will show how our projects work and why we are doing this.

What did we learn while doing the projects?

We learned to be careful while handling sharp objects and also while handling a glue gun. We also learned a lot about our projects by doing research and also learned about how people use the scientific method. We learned a lot about what we needed to do for our projects and also about how to be independent when constructing our projects. We understood our projects very well.
