Roller Coaster

Roller coaster #1

The aim of this project is to make a working roller coaster.

Session 1

In my first lesson we had to make a design of a roller coaster with a loop and a hill and have it all most finished by the end of the lesson.  My design by the end of the lesson looked like this:

This is the video witch I watched to get some more info on my design.


Session 4

I was sick for 3 sessions so I missed out on quite a bit.

This lesson I joined  a group to make a roller coaster, they have all ready started building but they needed to finish their design to start building. We kept on trying work out a design out that would work.

Finally we worked one out. 

I didn’t get any thinking down because we were thinking of it for the whole lesson.




Session 5

we changed our design again because the spiral around the back would not build up enough momentum  to do the loop so we changed the starting point much hire.

I used a bull clip and a little bit of bluetac to start off with but it did not hold the pipe so I had to put a lot more on like you can see on the picture. It still dose not hold for a long time because all the bluetac made the bull clip even more heavy.


Session 6

We had to change our design again because the bluetac would just not hold so we changed it to some thing that would be at the bottom of a roller coaster when we join it.

This is a photo of the almost finished product.

This is a video of it working.



Session 7

we had to change the design because we wanted a loop in the roller coaster so we got a box and stared building. I had to completely change my design because the box was way taller than the box we use to have


This was the box when it was done we had a loop witch was quite dificled because we had to have a massive drop to make the loop. The loop only worked with a little marble not a normal sized one another issue was getting the funnel in the right place so the marble could  go right though it.


You wont be able to see the marble even if I put it as slow as it can go. 🙁

Next we are going to join our roller coaster with another group so we can finish it.


Session 8 

To day we joined groups with another working roller coaster. We have to use a small marble so it can make it around the tight terns.In total we have tow loops and one jump. WE had to use a small bit of a bigger pipe and some things to holed the big pipe and the tow other pipes together.


we have to take it apart because it takes up tow much space.

Session 9



This lesson we spent most of the time brain storming ideas to make it go back up to the top of the roller coaster but we decided to have an tube which comes out of the loop and get’s elevated bye a bottle and jumps in tow the end of the bottle. [we cut the end off of the bottle] It took a few tries to get it working but we did it!

We had an ecserbishin today showing everyone’s roller coasters off. We had to set out all our designs out to show what and how we did it. I liked Alex’s group the best because they used centripetal force to make there loop work and they had a really cool roller coaster.



We named our roller coaster SMASH DOWN 2.0 because it had a really big drop and it all ways worked.



I really enjoyed this project because I learnt lot’s of things like centripetal force is where a invisible force  comes from the middle and pushes you out. I really liked building roller coasters because they gave me a good challenged for the term and they are really fun! We also had lot’s of fun presenting them to each other and coming up with cool names. I liked it because we had to make major decisions  to make the roller coaster work like re designing and building again and going back to the stage befor to make it work.

Welcome to your new Digital Portfolio


Welcome to your College Digital Portfolio! A Digital Portfolio is like having your own website. It is a place for you to learn about being an active and responsible digital citizen by creating a portfolio of your best work to showcase and share with others. Through the creation of a blog, you will be able to write regular reflections and share your learning journey through photo and video with your teachers, parents, each other and possibly even experts from all around the world.

For more information and support, speak to your teacher, explore, play and learn from each other! Learn how to publish your first post by visiting Publish your First Post. After that see what you can do! Visit the Edublogs User Guide for more help developing your new online space.

There are so many ways in which to use your space, for example:

  • Documenting and reflecting on your learning, passions, and interests, both in and out of school
  • Curating and highlighting work for your Student-Led Conferences
  • In some instances, your teachers will also ask you to submit, reflect and comment on other students work in this portfolio

That’s enough to get you going. Your Digital Portfolio should be a fun, enriching and rewarding way to explore, find or create your place in the world. Good luck!
