Designing an Experiment:
First I will create a blue print of my roller coaster. Then I will decide upon the independent variables, dependent variables and constant variables. I will understand the hypothesis and make prediction. Then I will go ahead and design my experiment

What are the factors that you would consider while making a marble/ ball roller coaster?
The most important factors are

1. The kinetic energy
2.The potential energy
3. Gravity
4.drag
5.Friction

If you had to make a roller coaster game using your learning about measurements, what would be the main elements of your game?

The main measurements will be the height in cm and angle of the slope in degrees ,the mass of the marble etc.. Since marbles can't go in loops I will make a wavy track that goes up hill and downhill.

What would be the most exciting part of this experiment?

The most exciting part of this experiment is that I can share it with my friends and can play with and steadily fix all its bugs

If I were to create a roller coaster,
The main factors are the conditions of the track, Size of the track, material of the roller coaster, size of the marble and the amount of friction between the track and the marble. I can make it interesting by making children to build their own tracks. The main elements can be the ball and roller coaster. the most exciting part of the experiment is going to be testing and building the roller coaster ride. The most important thing to consider is going to be safety. Kids below 10 years must be guided by their parents.

If I were to create a roller coaster, some of the factors I would consider are I distance it would go, the speed I want so its safe and exciting at the same time, the weight of the carts.

# data[].attributes.body
If I had to make a roller coaster the factors i would consider are the length and height of the ramp, whether it is possible for the ball to complete the roller coaster, The design of the roller coaster, And I will have to consider the size of the ball and make the size of the track accordingly. My favorite part of making this would be timing different balls and seeing which one goes fastest.

# data[].attributes.body
1. roll the ball farther and farther and then see how much power it takes to roll it to the start.
2. playing it and getting new results

3.how much power, what marble, the track will be plastic

I would choose a proper place. Type of marble, length of the track and the roller coater, materials, decorating it with proper safety. And proper density for the track and the roller coaster because if the roller coaster is to heavy then the track is going to break.

# data[].attributes.body
If I were make a roller coaster game we have to measure the density of the ball/ marble and I need to measure the length and width of the track. Also I think that if i did this experiment in real life my favorite part will be the part where i actually test it out and see if it works.

If I created a roller coaster, I would use

If I were to create a roller coaster game, I would. Firstly, I would make the track for marbles the track 1 cm wide with 3 tracks and it will be 2 meters long.
I would make a wood track with it being smooth enough for the marbles. It will cover the bottom, left and right parts of the marbles with wood walls so wind doesn't affect the marble.
The most exciting part would be a loop where the marble will be pushed with bumpers to get enough speed to go up the loop (all tracks meet here).
Lastly there is a timer and if you can blow your marble to increase speed, you may just get a fast time on the track.

Q1: What would be the most exciting part of this experiment?

A1: The most exiting part would be designing creating and decorating

Q2: What are the factors that you would consider while making a marble/ ball roller coaster ?

A1: The first thing I would consider is what am I making the coaster out of. Is it wood ,plastic, Foam etc. What size or weight is the marble. What is the length of each track , how high are the slopes, Will the marble be in a miniature cart or just roll on the tracks, How will the marble climb the slopes etc.

# data[].attributes.body
I think the most exiting part of the experiment would be testing it. i think the factors i need to consider is how the roller coster would be shaped and how the conditions of the track be like.

# data[].attributes.body
If I were to make a roller coaster game, there would be a lot of factors that I would have to conser. I would have to consider the material of my game, the length of the slopes and the time it takes for the marble to finish the roller coaster. To make it more fun and interesting for others, I would like them to create the game and I would give them all the necessary materials. I would also keep copies of the ready made game.  There would be different routes for the marble to tke and the person who figures out the best route and has all 5 marbles to finish the coaster would win the game. I would make sure all the materials are the same and the mass of each person's marble is the same too.

# data[].attributes.body
If I was going to create a roller coaster game the main elements of this coaster is going to be the distance it goes and the length of the slopes and the time it takes to finish the project. The most exciting thing is going to be the slopes and the decoration. The people on the coaster will be given an item and if you don't loose it at the end of the ride you will be rewarded

If i created a roller coaster I would make it go forward for 15m and then there would be a loop which is 20m then they will go up for 28m and come down for another 28m. I would also have to measure the ball which i could make 800g. Personally I think the most exciting part would be the testing to see how the marble will go.
