   Question 26

   A group of students test how far a toy truck rolls on four different flat surfaces: concrete,
   grass, gravel and sand. They give the truck a quick push and let it roll across each surface.
   They measure how far the truck rolls before stopping.



   To improve the results, the students create a list of changes that other students should make
   when repeating the experiment:



   Always use the same truck.

   Use a ramp to let the toy truck roll down onto each of the flat surfaces.

   Use the same methods to measure the distance the toy truck rolls every time.

   Collect data three times for each type of surface.



   Choose two of the tips from the list. In your Answer Document, explain why each tip helps
   improve the results of the investigation. (2 points)
