A biology teacher has come up with a unique way to keep her classes interested while she teaches them about science.
Debby Heerkens, a biology teacher at the Groene Hart Rijnwoude school in the Netherlands, has her classes enthralled as she teaches about the body's internal organs and the skeleton.
And her method couldn't be more simple.

In the video, which was shot while Debby was teaching, she takes off her top layer of clothes to reveal a spandex body suit covered with an accurate representation of the body's organs.
She then teaches her class while pointing at different organs, allowing her pupil's to see exactly where each one is located on a real human body.
Debby originally discovered the educational body suits while browsing online, and immediately checked with her school's director about whether she would be able to use them in her classes.
 
  She was given the go-ahead, and promptly introduced the suits into her classes, allowing her pupil's a more 'interactive' learning experience.
Debby told a Netherland's news site: "I saw someone walking in the muscle leggings last year.
"You're always looking for ways to trigger students and teach classes so that they remember [the lessons].
"I told the director that I had bought the suits, and he liked it too."
And now pupil's in Debby's class are already asking when their next body suit lesson will be.
A spokesman for the school said: "With Mrs Heerkens there is always something special!
