Objective
The purpose is to test whether the surface texture of the ground affects the distance an object can roll.
Hypothesis
If an object rolls over (type of material), then it will (describe the prediction of distance it will travel).
Materials
For this lab, I used the following items:
Steps, hard-cover books, blocks, or boxes to hold up the ramp
Wood, foam board, hard-cover notebook, cookie sheet, or other flat surface for ramp
Small ball (rubber, golf, tennis, etc.) or a can to roll down the ramp
Ruler or tape measure; or Print a Ruler
Towel, carpet, cotton fabric, sandpaper, or other materials to alter the surface texture of the ground
Procedure
Short summary of what I did:
I experienced the following errors while doing my experiment:
Test (independent) variable (What was different about my test groups?):
Outcome (dependent) variable (What was I measuring?):
Data
Record the distance traveled for each of the trials for the three floor surfaces in the table below.
Distance Object Traveled
Floor Surface Trial 1 Trial 2 Trial 3
Data Analysis
Calculate the average distance traveled for each floor surface. Use the following guidelines for calculating averages, and show your work.
Floor Covering Calculation of the Average Average Distance Traveled
Example (trial 1 measurement + trial 2 measurement + trial 3 measurement) / 3 (number of trials) Your answer from the calculation, showing the average distance the ball rolled for that floor covering.
Conclusion
Answer the following questions in complete sentences.
Describe in your own words what friction is.
Describe how friction affected the results of your investigation.
Does an object travel farther on a smooth or slippery surface or on a rough surface? Why?
Propose another experiment that could be used to demonstrate that friction is a contact force.

The correct answer is deferred imitation
Deferred imitation is known as the ability to reproduce a behavior or series of behaviors later than when it actually occurred.
The beauty behind deferred imitation is that it can provide us with a wealth of information about your baby's cognitive development, involving a combination of complex cognitive processes. Several studies demonstrate that imitation is a fundamental channel for development and socio-affective learning. In fact, it was found that observation may have a greater effect on the acquisition of skills than conditioning or the trial and error process.
