Sefton Central Labour MP Bill Esterson joined staff and pupils at St Michael's High School as they welcomed a Lab in a Lorry to the school.
Budding physicists got the chance to try out a range of experiment in the eight-wheel lorry.
Lab in a Lorry is an interactive mobile science laboratory which is staffed by practising scientists and engineers.
The lorry travels around schools and gives pupils the chance to carry out experiments.
Bill Esterson, who himself had the chance to watch some of the young St Michael's scientists in action, said the lorry is a good supplement to the classroom learning already provided in schools.
Bill said: "The facilities available to young people in schools now really is excellent. But what the Lab in a Lorry provides, is an opportunity for the pupils to experiment outside of the classroom and school laboratories, under the guidance of scientists and engineers.
"The young people I met were clearly very impressed by what they saw. And I was impressed by the skills they showed during the experiments.
"The equipment in the Lab in a Lorry really is excellent and the activities are fascinating.
"I wish we had a Lab in a Lorry when I was at school."
Bill said the scheme could help Britain find its next generation of scientists and volunteers.
Bill said: "There is a shortage of young people going into the sciences at the moment. We need more people becoming engineers.
"Lab in a Lorry is a particularly good scheme because it gets young people interested in science.
"By letting young people get hands on experiences of science, it can spark their interests and they can then go on to pursue that in their career.
"I'd like to thank St Michael's headteacher Dr Simon Hulme, Louise Butcher from the Institute of Physics, the Lab in a Lorry team and the pupils for allowing me to come along and see the young scientists in action."
