Objective

By the end of this lesson, you will be able to use statistics to analyze and interpret data related to your RC cars.

Materials and Prep

• RC cars
• Stopwatch or timer
• Pen and paper

No prior knowledge is required for this lesson.

Activities

1. Measure the speed of your RC car:

   • Set up a race track with a designated start and finish line.
   • Use a stopwatch or timer to measure the time it takes for your RC car to complete a lap.
   • Repeat the process multiple times and record the times.

2. Analyze the data:

   • Calculate the average lap time by adding up all the recorded times and dividing by the number of trials.
   • Identify the fastest and slowest lap times.
   • Calculate the range by subtracting the slowest lap time from the fastest lap time.

3. Create a bar graph:

   • Use the recorded lap times to create a bar graph, with the x-axis representing the number of trials and the y-axis representing the lap times.
   • Label the bars and add a title to the graph.

Fifth Grade Talking Points

• "Statistics is a branch of mathematics that deals with collecting, analyzing, interpreting, and presenting data."
• "In this lesson, we will use statistics to analyze the data we collect from our RC car races."
• "We will measure the speed of our RC car by timing how long it takes to complete a lap."
• "By repeating the process and recording multiple lap times, we can get a better understanding of the car's performance."
• "We will calculate the average lap time by adding up all the recorded times and dividing by the number of trials."
• "We will also identify the fastest and slowest lap times to see the range of performance."
• "Lastly, we will create a bar graph to visually represent the lap times and compare the different trials."
