Body Systems Bluff is a free printable science game for Year 7 (ages 11 to 12), in Key Stage 3. Players match each organ to its body system, or bluff. It is for 3 to 6 players, takes about 20 minutes and needs only paper, a pencil and scissors. Page 2 gives the grown up notes, help, a stretch idea and the answers.
It comes from the Mini Minds Hub, the free library of printables from Jaques of London, the British games and toy company that has been making games for families since 1795. Print both pages, use page 1 for play and keep page 2 for whoever checks. Black and white printing works well.
What is on the sheet
Page 1 gives you cards to cut out and use. Each card shows an organ from the human body, such as the heart, lungs, stomach, brain, kidneys or skull. Players link organs to the body systems they belong to. Sometimes a player may bluff, so the group has to decide whether a match is true. The talk and the reasons matter as much as the points.

Organs and body systems
Living things are organised in levels. Cells are the basic building blocks. Similar cells form tissues. Different tissues join to make an organ, and each organ has a job to do. A group of organs that work together to carry out a bigger job is called a body system. Year 7 science introduces this idea of cells and organisation.
A bluff game suits this topic well. To spot a false match, players cannot just remember a name. They have to think about what an organ does and which job it helps with. Explaining why a match is wrong is a strong way to check understanding. It also shows how the systems of the body depend on each other.
Quick facts about the body
- Cells are the basic building blocks of all living things.
- Similar cells working together form a tissue.
- An organ is made of different tissues that work together to do a job.
- A body system is a group of organs that work together.
- Body systems do not work alone. They depend on each other to keep a person alive.

This sheet supports the area below. It is matched to the published England framework. Please check it against your own school plan.
| Framework | Subject or area | Strand | Year |
|---|---|---|---|
| National Curriculum (England) | Science | Biology: cells and organisation | Year 7 |
What children will be able to do
- I can name some organs and say what they do.
- I can match organs to their body systems.
- I can spot a wrong match and explain why.
Ideas to help players decide
- Think about the jobBefore choosing a system, ask what job the organ does for the body. The job is a better clue than where the organ sits.
- Think in teamsA body system is a team of organs. If you know one organ in a team, ask which other organs might work with it.
- Say the names aloudRead the system names out loud before you start. Hearing them helps players link each organ to a group.
- Challenge with whyWhen a match looks doubtful, ask the player to give a reason. A good reason is more convincing than a confident voice.
Key words
- OrganA part of the body made of different tissues that does a particular job.
- Body systemA group of organs that work together to do a bigger job for the body.
- TissueA group of similar cells that work together.
- CellThe basic unit that all living things are made of.
- FunctionThe job that something does.
- BluffTo say something that may not be true, hoping others will believe it.
How to use it
- Print both pages. Page 1 is for the players. Keep page 2 for the grown up who checks.
- Cut out the cards. Read the rules out loud together, so everyone plays the same game.
- Gather 3 to 6 players. Read the system names aloud first, then start. A round takes about 20 minutes.
- If players disagree, check the answer page. Talk about why a match is right or wrong.
- Come back another day and play again. Repeating a familiar game builds confidence.
Help, stretch and game ideas
If it feels too hard
Read the system names aloud first. Then take one organ card at a time and ask, "What does this organ do?" Say the job in one short sentence before choosing a system. Play with the cards face up for a round, so no one has to guess.
To stretch confident children
Add a point for naming a job the organ does. Players can also try to explain how two body systems work together. Ask them to give a reason for every bluff they spot, not just say that it is wrong.
Make it a game
Play a second round and try to remember the matches. Before you check, see who can recall the most correct matches from the first round. Take turns being the person who reads and checks the answers.
Talk about it
- Which body system does this organ belong to, and what does it do?
- How did you decide that a card was a bluff?
- How do two body systems work together?
- Which organ was hardest to place, and why?
- What clue makes a bluff easy to spot?
- If you could explain one organ to a younger child, which would you pick?
Take it off the page
Draw a body outline
Draw a simple outline of a person on a large sheet of paper. Draw or stick organ names where you think they belong. Compare with a science book afterwards.
Make your own bluff cards
Write a true statement and a false statement about an organ on separate cards. Swap with a friend and sort them into true and bluff.
Body systems talk
Choose one body system. Take two minutes to explain to a family member what it does for the body, without using notes.
Who it is for
Parents
Play the first round alongside your child, and let them lead the second. Ten to fifteen minutes is plenty, or play for about 20 minutes with a group. Ask why, not just which. Page 2 has the answers if players disagree.
Teachers
Use it as a starter, plenary, early finisher task or table activity linked to cells and organisation. It needs no preparation beyond printing and cutting. Page 2 gives support and stretch ideas for mixed ability groups, so you can match it to your plans.
Home educators
Print it as part of a wider science plan and pair it with books and everyday talk about the body. It works well for brothers and sisters, and again a few weeks later as revision. Short, focused rounds work better than one long session.
Where this fits
In Key Stage 2, children meet the human body in pieces. They learn about skeletons and muscles, the digestive system and the circulatory system. Body Systems Bluff builds on that by asking Year 7 learners to link organs to the systems they belong to.
Later in Key Stage 3, learners go into more detail about how organs and systems are structured for their jobs. Being able to name organs, say what they do and link them to a system gives a firm base for that work.
Check it worked
Ask these when the sheet is finished. Listen for the reasoning, not just the answer.
- Which body system does this organ belong to, and what does it do?
- How did you decide that a card was a bluff?
- How do two body systems work together?
Questions parents and teachers ask
- What age is Body Systems Bluff for?
It is written for Year 7 (ages 11 to 12), in Key Stage 3. It supports the cells and organisation strand of National Curriculum science in England. Older or younger children can play too, with extra help or a harder challenge.
- How long does the game take?
It takes about 20 minutes. Play a shorter round if time is tight, or add a second round if players want more. Short rounds work better than one long game, so stop while everyone is still enjoying it.
- How many people can play?
The game is for 3 to 6 players. A parent can play with one or two children, and a teacher can run it with a small group at a table. Take turns being the person who reads and checks.
- What do children practise?
They practise linking organs to the body systems they belong to. They also practise recall, scientific vocabulary and giving reasons. Spotting a bluff means explaining why a match is wrong, which is a good sign of real understanding.
- What if it feels too hard?
Read the system names aloud first. Then take one organ at a time and ask what job it does. Play with the cards face up for a round. Page 2 has further ideas for children who find it difficult.
- Where are the answers?
The answers are on page 2, which is for the grown up. Use them to settle any disagreement. Ask players to explain their reasoning before you reveal the answer, so they think it through rather than just guess.
- Is it free and screen free?
Yes to both. It is free to print for home and classroom use, and it needs only paper, a pencil and scissors. It prints well in black and white on plain A4, so there is no need for colour ink.
