There are three parts to this activity.

• Body fact file - learn where major bones and organs can be found in the human body, what they look like and what each does. You can rotate the body to see how they all fit together. 

• Interactive Body Builder - lets you find out where the various body parts, including the bones, are positioned in the body by placing them yourself. Click and drag the organs and bones onto the 3D body outline. If you get it right the body part will stay in place, if you get it wrong it jumps back so that you can try again. If you have difficulty, turn on the 'Hints' to help you.

• Against the clock - presents you with a challenge to click and drag the body parts into their correct positions in the body as quickly as you can.
