Results from Newton's Lab... who says getting hit in the head can't help you?

After a long time I was able to have fun with pulleys and loads. We were to differentiate between mass and force with acceleration. There were 5 different cases we were to follow and produce results. These are the results that I collected with my group :) 

Data collected from the 5 cases

The tower is falling down... falling down

So last week we did another fun activity: constructing a tower. I should mention its not as easy as it sounds with limited tape and newspaper, yet again. That was all we received with even less time! My group and I started with cylinders for the base and for the top we rolled the rest of the papers and stuck it on the top. However, the top was ending up with more weight. Thus, it kept bending :(  We tried repeatedly to fix the problem but it's not like we had any more materials to strengthen the base. Then out came Mr.Chung and said time out. We tried to improve it even after time was up :P well until Mr.Chung was judging our (if you can even call it that) tower... So now it is evident that we were unsuccessful. But all creators fail at some point or the other right? I take this in the positive way and I know what I would have to do to produce better results next time :)

How it all started...

so yeah it won't stay down :P

How High Can You Go?

Ever wondered if there are structures taller than our own CN Tower? Well in reality the CN tower is ranked around the 100's for tallest structure. At number 1 we have Burj Khalifa with an enormous height of 828 m (2717 ft.) What has enabled this structure to maintain such a grand height? Usually when designing a building the main considerations to create a successful building is:

1. The use of strong, unbreakable materials
2. The shape. Usually we see buildings decrease in width from top to bottom. This increases stability. Of course we can't forget the triangles. It had been put into our heads since grade two that it is the strongest shape out there!
3.Weight can be another factor. We can't have a heavier top than bottom... The base should have the most mass.
4. Having a low centre of gravity which minimizes risks and difficulties

Burj Khalifa - Tallest Structure in the World!

What Goes Up Must Come Down!

   We have now started a new section in our unit in kinematics : projectile motion. It seems very complicated at first but eventually you get the hang of it. These are the answers from 1-9 in the projectile motion worksheet.
