Answer:Here are some guide questions along with suggested responses:### Guide Questions1. **What part of the wood helped the ball to roll faster?** - The smooth surface of the wood likely helped the ball to roll faster by reducing friction. A polished or flat area allows for less resistance against the ball's motion compared to rough or uneven surfaces.2. **When another hollow block or thick book was added, how fast did the ball roll?** - The addition of another hollow block or thick book may have altered the incline or surface of the ramp. Depending on the height and angle created, the ball may have rolled faster or slower. If the incline increased, the ball would likely roll faster due to gravity; if it became less steep, the speed might decrease.3. **What science ideas can you formulate based on the activity?** - This activity illustrates concepts such as gravity, friction, and momentum. The speed of the ball is influenced by the ramp's incline (gravity) and the surface texture (friction). Additionally, the mass of the ball and the objects used can affect its rolling speed and distance, demonstrating principles of motion and energy transfer.
