Laboratory work lies at the heart of science studies . Most of the intermediate and secondary schools have their own science labo ratories . There are a few exceptions such as Beersheba where a , central laboratory serves several schools . On the whole , the equipment in the science laboratories is adequate , except in physics for the highest grades , 11 and 12 . Modern physics is taught in these grades . This calls for sophisticated and costly equipment which is not now available in sufficient supply . The repeated budget cuts have caused a shortage of disposable equipment and have compelled the schools to have more and more pupils in the laboratories at anyone time . This results in a reduced effectiveness of science laboratory work .
