Data Journey Mapping Worksheet

Year 5 Science – Digital Systems

Digital devices collecting and sending data

🎯 WALT & Success Criteria

We Are Learning To: understand how digital systems collect, process, and transmit data from one device to another.

I can:

Explain how a digital device collects data (e.g. steps, heart rate)

Show the flow of data using arrows between devices

Use sequencing words: first, next, then, finally in my explanation

(Extension) Describe how data travels over the internet

Tick each box when you feel confident! ✅

📱 Part 1: Label the Device Cards

Each box below represents a device or component in a digital system. Write the correct label inside each box. Choose from: Smartwatch, Smartphone, App, Server

💡 Hint: Think about what collects the data first, then where it goes next!

1. This device is worn on your wrist and collects data like steps and heart rate.
2. This handheld device receives the data from the wearable via Bluetooth.
3. This software on the handheld device organises and displays your data in charts and graphs.
4. This powerful computer stores large amounts of data from many users over the internet.

🗺️ Part 2: Map the Data Journey

Draw arrows between the device icons below to show how data flows through the system. Then write a sequencing word on each arrow from the word bank.

Word Bank:   First  |  Next  |  Then  |  Finally

💡 Draw your four devices as labelled boxes. Connect them with arrows in the correct order. Write a sequencing word on or near each arrow.

5. Which device collects the data? Circle your answer.

Server

Smartwatch

App

Smartphone

6. Which of the following best describes what the server does? Circle your answer.

It collects steps and heart rate from your body

It displays data in charts on your screen

It stores large amounts of data from many users

It sends Bluetooth signals to your wrist

7. What type of connection does a smartwatch typically use to send data to a smartphone?

USB cable

Bluetooth

Satellite

Radio tower

✏️ Part 3: Explain the Data Journey

Use the sentence starters below to write a paragraph explaining the data journey in your own words. Try to use all four sequencing words!

8. Complete the paragraph using the sentence starters as a guide:

First, the data is collected by ___________________________________________

Next, the data is sent to ________________________________________________

Then, the data is processed by __________________________________________

Finally, the data is stored on ____________________________________________

Now write your full paragraph here:

⭐ Extension: How does data travel over the internet to reach the server? Write 2–3 sentences describing what you found out.
