Transformer experiments - For non-specialist physics teachers

(0)
Attached is everything you will need to teach a lesson (with a class practical or demonstration) on transformers. Using a multimeter that can measure AC voltage (available at places like Maplins), and a set of transformer coils (available from Phillip Harris) students measure the voltage across the primary and secondary coil of a transformer. Included are student instructions, guided questions, and teacher set up instructions. PLEASE MAKE SURE YOU HAVE A MULTIMETER THAT CAN MEASURE AC VOLTAGE BEFORE PURCHASING! See cover image for all equipment you will need!

A worksheet aimed to teach students how to convert from Kelvin to Celsius and vice versa. Students have to calculate the surface temperature of planets in the Solar System, and then plot a graph of distance from the Sun v temperature. Then use the graph to answer questions.

Resistivity/Resistance investigation - Length vs. Resistance of pencil graphite

(0)
I made a PowerPoint a few years back on how to make a resistor with pencils. Here are (differentiated) instructions explaining to students how to carry out the investigation. Included is the original publisher file if you want to edit it. If you don't have publisher a PDF is also included! To do this experiment you will need a digital multimeter that can measure resistance.
