Workshops for Schools
Tensile testing workshop
Tensile Testing
Who: Y11 (high ability) - Y12 Physics
How many: 20 students
Duration: 1-1.5 hours
Students will work in groups of 4 to measure the tensile strength of different materials using a simple tensile tester kit. Each group will plot stress/strain graphs for the material and use these to determine Young’s Modulus. Values for Young’s modulus will be compared to standard values and the experiment evaluated.
Solar cells workshop
Solar Cells
Who: Y10-12
How many: 20-30 students
Duration: 1-1.5 hours
Students will work in pairs to construct a dye sensitised solar cell using a range of dye sources. The students will measure the voltage of their cells at different intensities of light and compare results for different dyes. Results will be discussed and the science behind the solar cell explained. Students will be asked to put forward ideas for further research in this field and their ideas will be linked to current research on solar cells in the department and in other HEIs.

Electrifying Experience workshop
An Electrifying Experience
Who: Y8-10
How many: 20-30 students
Duration: 1-1.5 hours
Students find out about the very invention that marked the birth of a new branch of chemistry, called electrochemistry: the “voltaic pile”. Students will build their own voltaic pile and investigate the effect of the number of cells on the voltage of the battery. Research in this area will be introduced and discussed.
Chocolate workshop
Investigating Materials Using Chocolate
Who: Y8-10
How many: 20 students
Duration: 1-1.5 hours
Students investigate the properties of materials to include hardness, density, and fracture energy using different chocolate. Students put forward ideas to make an ultimate chocolate bar and this is related to microstructure of materials and the effect of alloying.
