6D MOVIE!

   Hiya guys! Here's a short movie about Term 3 of grade 6D! this video lags, a LOT. I stayed up all night just to finish this... and it's finally finished! So here, enjoy! :D

Experiment: Changes In Material

   
   On Science, we were all divided into groups to do an experiment about the changes in material. I was in one group with Alia, Marcella, Keven and Isa. How did we do the experiment you ask? Well we used different kinds of materials and mix them with other kinds of materials. Some of the changes are reversible while others are irreversible.

    
 
 I remember us burning sugar and turning it into a caramel-like substance. Though, there was one problem, we couldn't peel off the burnt sugar off the spoon! We also did a chemical change; mixing baking soda with vinegar! Oh, how much i hate the smell of the vinegar.

We had so much fun doing this experiment! 

Here are some links related to the changes in material:

Trip To The Farm

For our grade 6 field trip, we went to the Beth Shalom Organic Farm! We were told to observe how to do asexual reproduction in plants and we even did it ourselves.

Here are some pictures!

    
This picture was taken when we were still in the bus on our way to the organic farm! It was quite a bumpy ride though with everyone around it felt like nothing happened. As we waited in the bus, we were so eager to get out and explore the world of plants! 

   
     Once we made it there, we were split into groups. I was in group 3, if I'm not mistaken. Every group went to different parts of the farm. Every path we took was surrounded by plants, though it is a plant farm, so there's no doubt that plants would be everywhere!

     
      By the look on my face, you could tell that I kind of felt uneasy when it comes to picking plants right from the soil! In this picture, we were told to pick dicotyledonous plants. At first, i doubted that the plant i was holding was a dicotyledon, though the farmer told me i was correct, and now i'm pretty sure it is!

 

 

 

 

       Here's a picture of the two classes, 6D and 6E combined! Now that i look at it, there were so many kids roaming that farm.

Making Electric Circuits

For our science project, we were assessed to make an electric circuit.

For me, making an electric circuit isn't so hard. once you understand how to make one, it's easy. I learned a lot more about electric circuits and now i understand how to make one work and how to not. Both parallel and series circuits are not that hard to make. I loved doing the project.

Gravitational and Frictional Forces

          Gravitational force is a force that can act at a distance from an object and it is the force of attraction between things and the Earth. It pulls things downwards to the centre of Earth. The strength of the force depends on different places and the distance between and object and Earth. The closer, the greater. It causes water to flow down and pulls a diver into the water. We have weight because of the gravitational force. As we move away from Earth, our weight decreases.

         Frictional force is a force that opposes motion. It's produced when two surfaces rub against each other. These are the effects of frictional force:

• slow down/stop moving objects.
• Prevent an object from starting to move.
• affect the movement of objects in different surfaces.

         There is a greater frictional force on rough surfaces than on smooth surfaces, so objects move more slowly on rough surfaces than on smooth ones.
         Air resistance is the frictional force acting on things through air. It pushes against a moving object and slows it down.
         Water resistance is the frictional force acting on things through water. It acts the same with air resistance, but with water. It's difficult to walk/run on water because of the water resistance slowing us down.
          Frictional force can be useful. They can also cause problems.

Frictional force is useful because:

• It helps us grip/hold on things.
• Prevent objects from slipping from each other.
• Helps to slow things down.

It can also cause problems by making objects:

• Wear out.
• Slow down.
• Overheat.

         There is a way to reduce friction between surfaces. We can use lubricants, rollers and wheels to help reduce friction. Less friction helps machines last longer. Rollers and wheels help us to carry heavy objects around.

           For science, we made a parachute to see air resistance!

Annual Project

It was the annual project week! The group and I had to make a architectural miniature for our science annual project. Since my group's topic was China, we had decided to make a miniature of the great wall of China! It took longer than we thought it would to make the Great Wall of China.

Here are the steps:

-First, we cut a big piece of cardboard into pieces that will then be formed into the walls.

-Second, we made a tiny house.

-Then, we painted the tiny house and the walls.

-After that, we stick them together, the walls side by side to make a long "great wall".

-Finally, we decorated the ground with pieces of green wrapping paper as grass.

  And it's done!

Once it was done, our miniature was displayed in one big room, along with the other groups' miniatures. It really looked amazing, i can tell!

My reflection:
By doing this project, i improved my cooperative skills. I did learn to be more responsible with the task i am given. I know how to identify the Physical and Chemical changes and see the difference.

The Math and Science Fair

At my school, there was a Math and Science Fair. All the works and projects  the students made were displayed in one big room, just like a museum! Each class went there to have a look around at the displayed works. There was even a stand where they display robots, kung fu fighting robots! There were so many unique stuff displayed in the fair. It was fun, i can tell.
