Have you ever noticed how things around us move in different ways? Some things move in a straight line, while others might turn, roll, or bounce. They also move at different speeds, which means some things move faster or slower than others. For example, a cheetah runs much faster than a turtle crawls, and a person kayaking moves slower than someone on a jet ski.
We can describe how fast or slow something moves using words like “fast” and “slow.” But did you know we can also measure speed? To figure out the speed of something, we need to know two things: how far it traveled and how long it took to get there.
Let’s imagine a car that travels 60 kilometers in one hour. To find out the car’s speed, we use a simple formula: speed equals distance divided by time. So, we divide 60 kilometers by one hour, and we find out that the car’s speed is 60 kilometers per hour.
We can measure speed in other ways too, like meters per second. For example, if a sprinter runs 100 meters in 10 seconds, we can find the sprinter’s speed by dividing 100 meters by 10 seconds. This gives us a speed of 10 meters per second.
Isn’t it cool how we can measure how fast things move? Now you know how to calculate speed, just like a scientist!
Thanks for learning with us! Remember to keep exploring and discovering new things every day. See you next time!
Speed Detective: Go outside and observe different moving objects like cars, bicycles, or people walking. Choose one object and estimate how far it travels in a certain amount of time. Use a stopwatch to time it and then calculate its speed using the formula: speed = distance ÷ time. Share your findings with a friend or family member and compare the speeds of different objects you observed.
Race Track Challenge: Create a small race track at home using toy cars or marbles. Use a ruler to measure the length of the track. Have a race and time how long it takes for each car or marble to reach the finish line. Calculate the speed of each racer and determine which one was the fastest. Discuss why some racers might be faster than others.
Speed Story: Imagine you are an animal that moves at a certain speed, like a cheetah or a turtle. Write a short story about a day in your life, describing how you move and what you see around you. Use your imagination to include details about your speed and how it helps you in your adventures. Share your story with your class or family.

Things around us move in many different ways. Objects can move in a straight line, turn, roll, and bounce. They also move at different speeds. Speed describes how fast or slow something moves. For example, a running cheetah moves much faster than a crawling turtle, while people kayaking move much slower than a jet skier.

We can describe speed using words like “fast” and “slow,” and we can measure speed too. To calculate speed, you need to know how far an object traveled and the time it took to travel that distance.
Let’s say a car travels a distance of 60 kilometers in one hour.

Speed equals distance divided by time. We can find the speed of the car by dividing 60 kilometers by one hour. The speed of the car is 60 kilometers per hour.

We can also measure speed in meters per second. For instance, a sprinter runs a distance of 100 meters in 10 seconds. We can find the speed of the sprinter by dividing 100 meters by 10 seconds, which gives us a speed of 10 meters per second.
I’m not quite that fast, but I have to run. See you next time!
