Sorting humans

We are all humans – but no two people are exactly the same.

People of all ages are humans with the same body parts.

All humans

All people are humans. We are similar in many ways: we all have a head, two arms, two legs and the same organs inside. We all need food, water, air and sleep.

Ways we differ

People are also different from each other. We have different heights, eye colours, hair and hand sizes. Even twins have different fingerprints.

Some differences come from our parents, like eye colour. Others come from how we live, like how strong our muscles are.

Collecting data

Scientists collect data to compare people. You could count how many people in your class have brown, black or other colour eyes. Show your data in a tally chart and a bar chart.

A bar chart makes it easy to see which group is biggest. Always label the axes and give the chart a title.

Sorting with questions

We can sort people using yes/no questions. Can you roll your tongue? Is your handspan more than 15 cm? Each question splits the class into two groups.

What I learnt

I know that humans are similar and different in many ways.
I can collect data and show it in a bar chart.
