Hands-on lab (please help with this I don't even have these items)
Materials:
Tape measure
Timer
Marble
Tape
Purpose: investigation.
Part 1: You will measure the speed of a marble an alternative surface and graph it.
Put a piece of tape on flat, smooth ground.
Measure the amount of time it takes for a marble to go to 1m (1m = 100 cm)
Part 2: You will measure the speed of a marble an alternative surface and graph it.
Put a piece of tape on a different surface (sidewalk, low pile carpet, cardboard, or crinkled aluminum foil
Measure the amount of time it takes the marble to go 1m or stop moving.
Procedure:
1. Set up the materials and find a flat, smooth surface to conduct the experiment on.
2. Place a piece of tape on the ground and measure out a distance of 1 meter (100 cm) using the tape measure.
3. Place the marble at the starting point (0 cm) and release it. Start the timer as soon as the marble begins to roll.
4. Record the time it takes for the marble to reach the 1-meter mark on the tape.
5. Repeat steps 2-4 at least three times to ensure accuracy and calculate the average time it takes for the marble to travel 1 meter on the flat, smooth surface.
6. Next, choose an alternative surface such as a sidewalk, low pile carpet, cardboard, or crinkled aluminum foil.
7. Place a piece of tape on the alternative surface and measure out a distance of 1 meter.
8. Repeat steps 3-5 for the marble on the alternative surface and record the time it takes for the marble to travel 1 meter or stop moving.
9. Compare the average times it takes for the marble to travel 1 meter on the flat, smooth surface versus the alternative surface.
10. Create a graph comparing the speeds of the marble on the two different surfaces.
11. Analyze the data and draw conclusions about the impact of surface smoothness on the speed of the marble.
Also I forgot to ad you ned to write a hypothesis to
Hypothesis: I predict that the marble will roll faster on the flat, smooth surface compared to the alternative surface. This is because the smooth surface will create less friction and resistance, allowing the marble to travel faster.
Write it like a 9th grader would write, thank you.
Hypothesis: I think the marble will go quicker on the flat, smooth surface than on the bumpy surface because there will be less stuff slowing it down when it rolls.

I'm sorry, as a text-based AI I am not able to physically conduct experiments. But I can help you set up the data table with the headings for each trial:
