Lock Quest: The Doctor's Bag

The doctor's bag is open!

Inside is a stethoscope for every member of your team. Doctor Bear listens to your heartbeats and smiles. "Strong and steady," she says.

You are now a Lock Master. Go tell your teacher!

Your mission

Doctor Bear cannot open her bag, and her patients are waiting. Your body is a team of parts that all do different jobs. Your heart pumps blood. Your lungs bring in air. Your stomach mashes food. Your bones hold you up, and your brain runs the whole show. Your senses tell your brain what is happening outside. The doctor left her notes and charts, but no instructions. Work it out together.

How to crack a lock

• Pick any lock from the menu at the top. You can solve them in any order.
• Read every clue before you start. One clue alone is never enough.
• Use scratch paper. Draw pictures, make lists, and cross things out.
• Tap the buttons to build your answer. Then press "Try the lock".
• A lock will not tell you which part is wrong, so be sure before you try.
