Picture of Paper Roller Coasters :)
As a science teacher, this is the best project I do all year.  I have yet to come across a project where students are more engaged.  They want to come after school to work on it, they ask to take the project home to work over the weekend, students are shocked when the class period has come to an end, and they all want to skip their next class to continue working.

The purpose of this project is to reinforce Newton's Laws of Motion through roller coaster physics.  The objective is to have a marble take the GREATEST amount of time to get from the top of the first hill to where the coaster ends. 

This instructable has also been submitted into the paper contest.  I know the competition is fierce so please vote for me!

Students will demonstrate ability to:

Plan and Create a paper roller coaster 
Evaluate and test and retest their roller coaster
Analyze how to best manipulate the forces of friction and gravity
Explain the difference between potential energy and kinetic energy
Calculate problems involving free fall
Create tracks to better understand centripetal force

This assignment can be easily differentiated... make the goal time longer, make the base smaller, limit the amount of paper or tape...

Below is a roller coaster I created as an example for my students.  The video starts with an explanation followed by a test run (around the 1:50 mark).  I tried to incorporate as many features as possible onto one sheet of card stock.  The last step has a video of a paper roller coaster I created a few years ago that includes an elevator.

Did you do one pack of card stock per group? I'm loving this as an idea for my Physics classes...

I teach physical science and my students started this project today. It is the first time I've tried it. I am giving each group 35 sheets of cardstock. I told them this is their "budget". If they need more they will have to buy their own. I am not sure how far 35 sheets will go; I'm on a budget myself.

I know card stock can be pretty expensive (especially the 110#). I used a big paper cutter and cut the sheets into thirds for them. 100 sheets sounds about right. I like the idea of putting them on a budget. Let me know how it goes and please send me any questions. Good luck!!

Thank you so much!

I cut the card stock into thirds so I only used about 3 reams for around 60 students. I had plenty of paper left over for whole sheets to be made into funnels and time wasters too. The hardest part is tape. The kids fly through it. When I was teaching in a public school I asked the kids to bring in rolls of tape from home. The way I set up the videos makes it really easy to flip the class. Have them watch for homework so they know what to do when class starts. The best thing for them to build on is foam core poster board, but cardboard works well too. The projects take up a fair amount of room so I need my students to move them from the lab tables to the floor at the end of class. The base needs to be firm so they can move them. Finally, to keep the room from becoming a total disaster, I tell the students that anything that falls off of their base is fair game. Other teams can take tracks, corkscrews, time wasters, supports... If they are on the floor. They're just not allowed to steal something off the base from another team and say they found it. There are so many variations to the project. Good luck and have fun. Let me know if I can help in any way.

Hey, sorry it took so long to get back to you. I usually try to keep students in groups of 2 or 3. When I taught on a 90 minute block schedule I would give them about 4-5 full class periods. Now that I'm teaching 45 min. classes, I give them about 10 class days. It's a long project. Often times, students will totally trash what they started and rebuild (where it becomes most clear to me that they are learning from mistakes).
