Applying a voltage difference across a conductor and measuring the current flowing through a resistor allows the resistance of the conducting material to be determined.
Year 12 student Ryan Phillips from Villanova College, Brisbane, used an electric bar heater in front of the solar panel. Making and testing a catapult - the trebuchet A catapult is any kind of device that shoots or launches a projectile by mechanical means. A small "spud" potato gun may or may not be a firearm depending on whether it can cause a bruise.
The fascinating thing about hydraulic jumps is that astronomers use them as models for white holes. But as Mohamed said " You could investigate the conditions and reason under which it becomes non-ohmic.
You could look at height or time of flight vs initial mass of water, pressure, nozzle area, mass of rocket. For instance 18 year old Eesha Khare of California developed a supercapacitor that can recharge a mobile phone battery in less than a minute.
For instance, if you put the end of a metal bar in a fire the rod will have a high temperature at the red hot end but the temperature will be lower at the other end close to your hand.
No metal rods in your lab - then unscrew a retort stand - that will do. Water discharge from a leaky bucket Whether its at hole in a dam wall or a leaky urn in the tuckshop - leaks are annoying.
One of the things you may need to measure is the speed of the projectile and this can be tricky. This increases the likelihood of electron collisions and decreases the current through the conductor.
These are the 16cm long pencils being used.
My thanks to Caitlin Ramsay for her help. The lift force acting on a rocket in flight is usually pretty small. The technique depends on the heat loss to the surrounding fluid from an electrically heated wire.
Therefore, the potential energy is transferred into rotational kinetic energy and to translational kinetic energy of the projectile.
