INTRODUCTION In this activity, students should be able to design ways to obtain the speed of each member of the group and decide how to use these values to determine who among them walks fastest. INTRODUCTION Guide Questions: 1. What quantities did you measure for your data? 2. How did you combine these quantities to determine how fast each participant was walking? 3. How did you use the result to determine who walked fastest? HYPOTHESIS Speed is expressed here in meters per second (m/s). To support their conclusion of who walks fastest, students will first gather data. They will measure the total distance travelled and the time taken to travel and divide the distance travelled by the time of travel. HYPOTHESIS O Students will conclude that the fastest participant was the one with the highest computed value of distance over time. HYPOTHESIS O Students will eventually learn that speed is term used to describe how fast an object/person is moving and it is obtain through dividing total distance travelled by the time taken to travel and mathematically expressed as S = d/t where S stands for speed, d stands for distance travelled and t stand for time taken to travel. HYPOTHESIS O The manipulated variable is time and distance. O The responding variable is speed. MATERIALS O Meter stick O Ribbon O Timer (Cellphone) O Paper O Pen PROCEDURE 1. Start by choosing a spacious place to walk straight. 2. The students will be grouped into 6. Each group must choose a pair to represent them and the rest of the members will observe and record data. 3. Mark on the ground the starting line. All participants must start from the starting line at the same time. PROCEDURE 4. Upon receiving the go signal, all participants must start to walk as fast as they could. The other members should observe closely as the participants walk and determine who walks fastest. 5. Repeat step 4 but this time, the students will collect data to support their conclusion and discuss within their group how they are going to do this.

The students measured the total distance travelled and time taken to travel the distance which is the required quantity to solve for the speed. CONCLUSION O To obtain speed, total distance travelled is divided by the time taken to travel. It is mathematically expressed as S= d/t, Speed = distance /time. The one with the highest computed value of distance over time or speed is the fastest.
