Everyone can collect data
ICT P5 Term 2, Theme 3: pp. 8–13
GoalExplain how many small records become useful data, and plan a safe litter walk on paper.
New words
data · facts we collect, such as counts, places and kindsrecord · one note about one thing you foundupload · to send a record from your device to a shared place on the internetlitter · rubbish left on the ground where it should not be
Explanation
One person walking along a street cannot count all the litter in a town. But if many people each write a short note about what they find, the notes together make a big picture. This is collecting data. A phone app can make it easy. It takes a photo, saves the place where you are (satellites in space tell the phone where it is), and asks the kind of litter: paper, plastic, metal or glass. Then the record is uploaded and joins thousands of other records. Children can do this at school, but always with a grown-up. Wear gloves, never touch anything sharp, wet or medical, and tell the grown-up at once. Do not put faces or house addresses in a photo.
Take a photo→Save the place→Choose the kind→Upload the record
Worked examples
Youssef finds three plastic bottles near the school gate. With his teacher he records one note: the place, the kind (plastic) and the number (3). One small record is ready to upload.
Group A finds 12 items and group B finds 8 items. The teacher adds the two records: 12 + 8 = 20. Small records add up to bigger data.
Salma sees broken glass in the grass. She does not touch it. She steps back and tells her teacher, who deals with it. Safety comes before data.
Class activity
Plan a litter walk on paper. Draw a table with four rows: Who comes with us (a grown-up and two friends)? What might we find? Which tools do we need (gloves, pencil, a tally table)? How will our numbers help (for example, to decide where a bin is needed)? Fill it in with a partner. Then draw a tally table with three columns: paper, plastic, metal. Pretend you walked around the school yard and make a tally of your own.
Practice
1
What does a phone app save with each photo of litter?
The place, and the kind of litter.
2
Two groups find 15 and 9 items. How many items are there in all?
24 items (15 + 9 = 24).
3
You see a sharp or wet item on the ground. What do you do?
I do not touch it. I tell a grown-up.
4
Look at the picture. Which one is safe to wear on a litter walk? Say the letter.
