At most of my schools we did science as 'Combined Science' that's to say physics, chemistry and biology as a single unified subject.
For instance we learnt about ohms law, series and parallel connections playing with battery DC cells, motors, lights and some pre-assembled modules.
For biology we used Microscopes to see very small particles from minerals, plants and small bugs.
We also dissected parts inluding very small mammals.
For physics we used bunsen burners to heat up various compounds taking care not to set fire to our desks or us as well being careful with gas .We also learned about energy and how a moving object can gain it.
We had to write up all our experiences properly with clear conclusions in our exercise books in neat handwriting.
