Description:

Dielectrics inserted between the plates of a capacitor will make the capacitance go up. This is because the dielectric causes the voltage to go down.

Recipe and
Location:

Adjustable Parallel Plate Capacitor
Power Supply
Photometer
Dielectric Sheets
Leads

None

Notes:

This one is hard to do, especially if the sheets get charged.

The photometer measures the voltage. Thus the reading will go down when the sheet is inserted meaning the capacitance goes up.
