More than half of schools have been forced to cancel science practical lessons because of kids messing about in class, a survey has found.
A total of 57% of schools said they had stopped at least one class because they were worried about kids getting hurt by things like acid or gas burners.
The survey was carried out by the Save British Science (SBS) campaign because it was worried kids were missing out.
It says practical lessons often inspire the scientists of the future.
"If there is a pupil who is known to behave badly, and cannot be removed, teachers do not want to take lessons which could involve acids or gas burners," an SBS spokesman said.
Other reasons
The survey also threw up other reasons for science practicals being cancelled.
These included lack of space, lack of equipment and classes being too big.
