Right now, sitting still, your body is still busy. What jobs do you think it is doing this second?
Hands up one job you can name. We will find out how those jobs are run by teams inside you.
Today's words: organ — a body part with one clear job. body system — a team of organs that share one big job.
Watch this example with the heart card. The heart's job is to pump blood around the body. Even though it sits in the chest near the lungs, we sort it by that pumping job, not by where it sits.
When we sort organs, we sort by the job the team does, not by where the organ sits in the body.
Here are our five teams: Breathing (brings oxygen in), Circulation (moves blood around), Digestion (breaks down food), Movement (bones and muscles that move us), and Control (brain and nerves that send messages and control what the body does).
In your group, sort every organ card onto one of the five team mats. Read the job on each card. Put the card with the team that does that job. If you disagree, say why before you place it.
Look at the interactive on the board. Ten organ cards appear: lungs, windpipe, heart, blood vessels, stomach, intestines, bones, muscles, brain, nerves.
Call out which team each belongs to: Breathing, Circulation, Digestion, Movement or Control. We will place them together and check our table sorts.
Sort the organs into body systems
On your Investigation Journal page, make a quick record of the sort we agreed.
Fully label three teams: write the team name, the big job it does, and the organs that belong in it. For the other two teams, write the team name and at least one organ each. Use your sorted cards to help you.
When your group has three full teams down, hand your mats to the front so we can use them next.
