Brownian motion - physics experiment
Brownian motion - physics experiment
http://www.fizik.si Brownian motion is the seemingly random movement of particles suspended in a fluid. Molecules of water move faster if the water temperature is higher. In the warm water the ink spreads faster. In the cold water molecules move slowly so the ink also spreads slowly. This is physic...

Buoyancy-cool science experiment
http://www.fizik.si Buoyancy-cool science experiment This video shows how the melting of ice changes the buoyancy force on the ice cube. Ice cube melting reduces their buoyancy and gravity is dominated force until a drop of water drops from the cube. At this point the lift force is greater than the...

Electric discharge - science experiment
http://www.fizik.si Flames are ionized gases and in some cases plasmas. The fact of being plasma or not, depends on the flame temperature and the burning material. A negatively charged baloons attracts positive ions in the lighter flame. The consequence of this is that the electric force between bal...

Under-cooled water - Science experiment
Under-cooled water - Science experiment
http://www.fizik.si In all study books we can find data that under normal conditions water freezes at temperature 0°C. This experiment shows us how the water can be under-cooled. We achieve that at less than -4°C the water is still in liquid aggregation. Yet a tiny change causes the phase change. ...

Science experiment - how to boil water with ice - Science experiment
http://www,fizik.si The experiment shows the dependence of the boiling point from the pressure. Fill a glass gourd with warm water and turn it over. Put an ice cube on the top. The ice cools the air in the gourd. The pressure of the air decreases and this causes repeated boiling of the water.

Ice and salt - science experiment - Science experiment
http://www.fizik.si When the salt (NaCl) is added to ice, sodium and chlorine separate. Ions of chlorine ally to molecules of water, what causes breaking of molecule forces that hold together the ice crystal. The energy needed for breaking these forces comes from water and this causes the temperatur...

Temperature of CO2 - Science experiment
http://www.fizik.si We've measured the temperature of dry ice - carbon dioxide. The temperature is in degrees Celsius.
Gadolinium - Science experiment
Gadolinium - Science experiment
Gadolinium is unique for its high magnetic moment and for its special Curie temperature (above which ferromagnetism vanishes) lying just a room temperature (293.2K), meaning it could be used as a magnetic component that can sense hot or cold. www.fizik.si

Heat conduction - physics experiment
http://www.fizik.si Wooden and metal pedestal stand in hot water. Since metal is a better heat conductor than wood, the ice cube on a metal pedestal melt faster than the ice cube on wooden pedestal. This is physics experiment for science project. http://www.fizik.si Lesen in kovinski podstavek po...
Heated glass - electric conductor - physics experiment
Heated glass - electric conductor - physics experiment
http://www.fizik.si Led diodes are connected to batteries and to a glass rod. There is a gap between two wires on the glass rod, so electric current can't run through the circuit. When the glass rod is heated, it starts to conduct electric current. Led diodes light up. This is physics experiment f...

Liquid nitrogen projectiles - physics experiment
Liquid nitrogen projectiles - physics experiment
http://www.fizik.si Film can is filled with liquid nitrogen and closed with a lid. Inside the can nitrogen is boiling and producing vapor. The pressure inside is increasing fast. When the pressure is high enough, the can explodes. This is physics experiment for science project. http://www.fizik.si...

Table tennis ball in liquid nitrogen - physics experiment
http://www.fizik.si A table tennis ball with two small holes is filled with liquid nitrogen. When the ball is placed on the table, it starts rotating, because of the nitrogen vapour. This is physics experiment for science project. http://www.fizik.si Žogico za namizni tenis preluknjamo ter jo na...
Magnetic Levitation - physics experiment
Magnetic Levitation - physics experiment
http://www.fizik.si Superconductor is cooled down using liquid nitrogen. When a magnet is placed over it, it levitates due to the expelled magnetic field from the superconductor. When superconductor warms up, the magnet falls down. This is physics experiment for science project. http://www.fizik....
Boiling water at lower air pressure - physics experiment
Boiling water at lower air pressure - physics experiment
http://www.fizik.si Water boils at lower pressure if the outer air pressure is lower than normal. Pump the air out of the container, so the air pressure in the container decreases. At a certain value (depending also on the water temperature) the water starts boiling. This is physics experiment for ...

Curie temperature - physics experiment
http://www.fizik.si This experiment shows that magnetic properties of the substance depend on the temperature. Magnet drags the iron swing. When the candle warms up the swing to a certain temperature (Curie temperature), the swing looses it's magnetic properties and the magnet doesn't draw it any m...
