Research Questions Student 1: Slippery or Sticky: Which Surface Creates More Friction? 1)How does the surface type - smooth, rough, textured affect the friction produced when objects slide or move across it? 2)How can you design simple experiments using everyday materials to measure and compare the frictional forces generated on different surfaces? Student 2: Friction in Action: Investigating the Effect of Surface Area on Sliding Resistance 1)How does the surface area of an object in contact with a surface impact the frictional force experienced during movement? 2)What conclusions can be drawn about the effect of surface area on the force required to move an object across different surfaces? Student 3: Friction Fighters-Exploring Ways to Reduce Friction in Everyday Life 1)What are some everyday scenarios where friction is helpful and hindering? Explain simple methods or materials to reduce friction in common situations, like sliding doors, playground slides, or skateboard wheels Student 4: History of science friction
