To Show Expansion and Contraction of a Solid when Heated
This video shows how a solid object expands when heated and contracts when cooled. This is experiment OP23 on the Junior Cert Science Syllabus.
This video demonstrates how a gas expands when heated and contracts when cooled. This experiment is OP23 in the Junior Cert Science syllabus.
This video shows how to conduct an experiment to verify Ohm's Law. This is experiment OP50 on the Junior Cert Science Syllabus. Heat transfer by convection, radiation, conduction Reflection of Light in a Plane Mirror Magnetic field of a bar magnet Conductivity of Solutions
We look at the electrical conductivity of several solutions. Substances include tap water, distilled water, sodium chloride, hydrochloric acid, sodium hydroxide, sugar, vinegar, ethanol, and barium sulfate. The solutions are mixed to approximately the same ratios. The tester is a pair of stripped copper wires at line voltage in series with a 25W incandescent bulb. The probe is rinsed in distilled water between each test.
