Community flowerpots: read minutes around the clock

An activity at a community garden starts at 2:00 and runs for 5 minutes. Change the controls and explain what the animation reveals.

Predict what will happen, press Play, then pause and explain what changed. Every control also works without playback.

A twelve-hour analog clock is used. AM/PM and calendar dates are not specified. The animated duration is measured in whole minutes, with normal hour-hand movement.

Understand what you are seeing

The idea behind the motion.

An activity at a community garden starts at 2:00 and runs for 5 minutes. The minute hand completes one revolution in sixty minutes while the hour hand moves continuously. Crossing the twelve mark on the minute hand can change the hour without resetting elapsed time. After 5 minutes the clock reads 2:05. A clock reading is a position in a twelve-hour cycle; the duration records how much time passed.

A relationship to keep

2:00 + 5 minutes = 2:05

Read the symbols alongside the explanation. A diagram shows the relationship; the assumptions tell you when it applies.

  1. STEP 1

    Read the starting situation

    An activity at a community garden starts at 2:00 and runs for 5 minutes. Identify what each number measures before changing a control; the worked example refers to these starting values.

  2. STEP 2

    Follow the mathematical change

    Move the timeline to advance elapsed minutes. Read the minute hand first and notice the hour hand's movement between numbered hours. Pause on an intermediate frame and compare the picture with the live readouts.

  3. STEP 3

    Explain and test the relationship

    After 5 minutes the clock reads 2:05. A clock reading is a position in a twelve-hour cycle; the duration records how much time passed. Change one input, predict its effect, and test whether the same relationship still works.

Your turn to explain

Make a prediction. Test your reasoning.

Community flowerpots: use the original situation. An activity at a community garden starts at 2:00 and runs for 5 minutes. What would the clock read five minutes after the planned end?

Use the values specified in the question. Reset restores the initial values for this investigation.

Compare your explanation

2:10. Add five to the elapsed duration, carrying sixty minutes into the next hour when necessary.
