In my investigation I used an AirPods case and I slid it on five different surfaces.
1. Cutting board
2. Placemat
3. Tinfoil
4. Book
5. Shirt
I set up the cutting board as a ramp and I slid my AirPods case down it. With all the other objects, I put them on top of the cutting board to the AirPods case could slide down them. For the book, however, I set it up as a ramp by itself.

In my investigation I used a toy car. And the surfaces I used were:
1.) T-shirt
2.) Placemat
3.) Book
4.) Cutting board
5.) Folder
I kept my test fair by measuring my ramp and making it the same height every time.
Here are my pictures=

When I did my experiment  I kept the table, the whitebord, the paper, the cutting board and the dishtowel at the same angle and I also always used the same pencil for all of the tests. The length of everything was always the same as well.

When I was doing my experiment I kept three things the same to make sure that the experiment was the same; the length of the ramp; the angle and the object that I used to move (an eraser.)

I slid an eraser against the floor, a cutting board, paper, a yoga mat, and my table

In my in yes ligation this was the first slope I used. Then I placed a resin pencil case on it measured the time. Then I placed different matirals like cloth or cardboard and tested the same thing.

in my investigation I used AirPods case and slid them among five objects:
1) a mirror
2) bed
3) carpet
4) paper
5)desk

here are some pics of my experiment:

To do this experiment I placed the end of my ruler at the starting spot of the case and then flicked the case on top of the selected surface. Then I measure how much the case moved, and repeat. I tried my best to make sure that the same amount of force on every attempt.

In my investigation I tilted a 32 centimeter box on a 45-degree angle and let the empty glasses case slide down.  To make sure it was a fair test I kept the angle the same,used the same case and let the case time go from the same point each time.

In our investigation we rolled a toy car over a piece of cardboard, a carpet, a T-shirt and wood. We didn't get the chance to take pictures, however the it rolled the furthest on the cardboard, which was 70 centimeters.  In each experiment we flicked the car across the material. We made sure that it always had the same amount of pressure released when flicked. The surface would be laid flat on the ground.

I placed a tennis ball alongside a ruler. Then I flicked the tennis ball with the same finger each time and measured the time it took for the tennis ball to traverse the distance. The surface was 180 degrees meaning that it was flat.

When I did my experiment I used this
30 cm surface
180 flat surface
I used the same tennis ball each time

When I carried out my experiment I kept the following things the same to make sure it was a fair test:
1. The length of the ramp
2. The angle of the ramp
3. I used the same lego car each time
